Introduction This is a step by step guide for creating a simple substation and overcurrent protection application using

the Helinks STS software.

Step-by-step guide

Getting started

1. Start Helinks STS by clicking on the icon on your startup screen or desktop.

2. When the first screen comes up, you can choose where to save your workspace and what to name

it. For the purposes of this presentation, the project is called FMTP WS.

3. The screen you shall see now is the dashboard. From here you have access to various aspects of the

tool such as single line diagram, system diagram, and communication. Please choose Single Line

Diagram by clicking on the icon.


http://www.fmtp.se/






Single Line Diagram

Once in the Single Line Diagram, you can design the substation you have in mind. This guide shows you how

to design the sample substation presented.

4. First, select “Substation” From the Substation tab on the right hand side of the screen. Then create

a box in the white field and name the substation AA1.


http://www.fmtp.se/






5. Select “Voltage Level” from the “Substation” tab on the right hand side. Create a box and name it

“J1”. In this example, there are two voltage levels due to the presence of a power transformer.

6. There are 5 bays in this example. One bay is under voltage level J1 and represents the feeder on the

incoming line. Other bays contain equipment inside the substation on the other side of the

transformer. To create a bay, click on “Bay” under the “Bay Type Library”. Like how substation and

voltage level were created, a bay can be made also. Name the first bay Q01.


http://www.fmtp.se/






7. Now, create another voltage level called “J2” and while that is selected and highlighted, create 4

other bays with the names Q02 to Q05.

As you have understood, the hierarchy is important in the structure of the substation. In order to ensure

bays are under the correct voltage level or in general, an equipment is properly placed under a bay or a

voltage level, you can check children of each bay or voltage level by right clicking on it and choosing “select

children”. In the picture below, you can see all the children under voltage level J2 highlighted which

includes Bays Q02 to Q05.


http://www.fmtp.se/






8. From the right hand side under “Bay Type Library” choose Bus Bar and create two Bus bars named

Bus Bar A and Bus Bar B. When you choose Bus Bar, you can drag it on the canvas to lengthen it.

Notice that Bus Bars don’t necessarily belong to a particular bay.

9. To place a power equipment, you can choose one from the right hand side under the “Power

Equipment” tab. As it was stated before, remember which equipment belongs to which bay. Select

the bay and when it is highlighted, then place the equipment on the canvas. The whole single line

diagram should look like the picture below. As you can see, each bay is highlighted with a different

color to differentiate between them. The equipment needed for this example are: Breakers,

Disconnectors, Power Transformer, and Feeders.

Also from the right hand side you can choose “Electrical Connection” to draw lines and connect

equipment to each other.

Function Specification Diagram

Function specification diagram is where you have access to logical nodes and can design various

applications for a corresponding bay, voltage level, or substation and assign functions to IEDs.

10. For the purposes of this guide, double click on bay Q03. The screen should resemble the picture

below.

As it can be seen, various appropriate logical nodes are already appointed to the breaker and disconnectors

accordingly. In this screen, you can create new functions for the bay such as protection, measurement, etc,

and you can populate them with different proper logical nodes. The logical nodes can be selected on the

right hand side under the tabs “IEC 61850-7-4” which show different editions of the standard.

In this example, we will assign an IED in Bay Q03 and one in Bay Q04. An overcurrent protection function

will be assigned to Q03 with the according logical nodes: PTRC, PTOC from edition 1 of IEC61850-7-4 which

is the first IEC 61850-7-4 tab.


http://www.fmtp.se/






11. To create a new function, simply click on “New Function” under the tab “Functions”. Then, on the

canvas, create a small box and name it “Overcurrent Protection”.

12. Open the tab “IEC 61850-7-4:2003” and choose the logical nodes “PTRC” and “PTOC”. Then place

them inside the “Overcurrent Protection” box.


http://www.fmtp.se/






13. Under the IED tab on the right hand side of the screen, choose “virtual”. Create a box on the canvas

and name it “IED 1”.


http://www.fmtp.se/






14. All the functions of the bay would have to be assigned to the IED if it is set for this particular bay.

Click on the “Connections” tab, then choose “Assign Device”. You will see an arrow on the screen.

Hover the arrow on the “IED 1” box, click and hold the mouse button, then hover it on one of the

functions, specifically the header. Release the mouse button and a line should be drawn from the

function to the IED. If you do it for all the functions here, the screen should look like below:


http://www.fmtp.se/






15. Go back to the Single Line, choose the bay Q04, create an IED called “IED 2” and assign the existing

functions to the IED. In this example, there is no need to create any other functions for this bay.


http://www.fmtp.se/






To create a communication application between bays, with the virtual IEDs in place, you can either import

an ICD file from a real IED, map the logical nodes placed in the function specification diagram, and create

the communication that way OR place generic IEDs, create the logical nodes needed and map them

accordingly and then create communication application.

The former method is the practical method where one has access to IEDs and designs the communication

according to the logical nodes the IEDs provide. However, if an IED is not accessible at the time, it would be

reasonable to create an IED based on the needs of the substation automation design and then buy an IED

compatible with the designed one. Hence, here the guide splits into two parts: practical method, and real

life method to reflect both situations. The steps are similar in many ways and differ in only a few, however

significant ways.

Practical Method

Import file

16. On this method, ICD files from existing IEDs will be transferred to the workspace. Go back to the

dashboard and click on the “Import” Icon.

17. For the purposes of this guide, we will import two ICD files from ABB REF 615 and Areva 5439 and

Siemens Siprotec. Just choose the according ICD file and press Open. Another prompt opens,

choose the following options and you should be able to upload the ICD files successfully.


http://www.fmtp.se/






System Diagram

18. Go back to the main screen and click on System Diagram Icon.

System Diagram is where you can configure the network configuration. As you can see, it has already been

updated with an ABB tab which is the result of the import of ICD file. In this screen, the network equipment

such as Sub network, HMI, IEDs, switches can be created from scratch. The ABB IED can be created by

choosing the icon from the ABB tab. The connection from the IEDs to the switch can be made using IEC

61850 Connection. For each connection, an IP address can be assigned. Since the IEDs are from ICD files,

the IP address will be assigned based on what is used in the file. The IEC 104 connection is used for HMI

communication.

In the end, the system diagram should look like the picture below.


http://www.fmtp.se/






19. Back on the Single Line screen, click on bay Q03 to move to the function specification diagram.

Right click the mouse button on the IED and choose “Implement IED”. Then choose one of the IEDs

placed in System Diagram. In this example, we choose REF 615.


http://www.fmtp.se/






20. The logical nodes present in the screen and assigned to the IED can be mapped to the ones already

inside the IED since we used an ICD file. It can be done by double clicking on the IED and choosing

the corresponding logical nodes. In this example, only PTOC and PTRC will be mapped.


http://www.fmtp.se/







http://www.fmtp.se/






As it can be seen, PHI.PTOC and TRP.PTRC were chosen in this IED. In each IED, various types of a particular

logical node exist with different prefixes. Based on the application for which they are being used, a specific

prefix will be chosen. The difference is in the signals they encompass and therefore the functionality they

represent.

21. Some logical nodes need to be defined for which purpose they should be used. Signal selection in

Helinks helps with that purpose. For this example, signal selection for PTRC will be shown. Right

click on PTRC and choose “Signal selection”.

Here, signals (or variables or attributes for the logical node) corresponding to the requirements of the

design will be chosen. Since PTRC is responsible for sending trip signals, we will choose Tr.general. It should

be noted that quality attributes of a signal will be automatically chosen by Helinks.

22. On the screen that is open, on the report tab, choose edit and then choose Tr.general which is a

status variable and click on the Add button to add the signal to selection.


http://www.fmtp.se/






Like it was mentioned before, most of the logical nodes placed in Helinks have proper signals already

implemented.

23. Back in Bay Q04, we will repeat the same steps to map logical nodes to the Siemens IED

implemented for this bay. There is no need to create additional functions since Siemens is on the

receiver end of the communication between Q03 and Q04. Practically, the logical node that

receives the message (or subscribes to it) is usually a generic logical node called GGIO. So, in this

step, we place a GGIO logical node inside the function for breaker CB4_1 based on how it was

explained before. Then, that is mapped to an instance of GGIO inside the IED.

Other logical nodes inside the breaker function can also be mapped which has been done like the picture

below.


http://www.fmtp.se/






Appropriate signals should also be chosen for GGIO to have the logical node act as one assigned to the

changing the breaker status or set for interlocking. In this guy, we refuse to delve that deep into this

process as it can be changed with each project.

With the implementation done, we can move on to create an application and design communication

between Q03 and Q04.

Application and communication design

24. Back on single line diagram, choose “Application” from the right hand side of the screen. Create a

box somewhere on the canvas and name it Protection Practical. You can also assign an AppID to it

in the properties menu.


http://www.fmtp.se/






Right click the mouse button on the application and choose “Open application”.

25. In this view, we can design the communication application. From the palette on the right hand side

of the screen, we choose sending and receiving functions. Sending is Overcurrent function from bay

Q03. Receiving function is CBR4 from bay Q04.


http://www.fmtp.se/






26. By right clicking on the sending function, you can choose which signal to use. In this application,

Tr.general from PTRC is used. Then by choosing “Medium Connection”, hovering the mouse over

the selected signal on the sending function and holding the button and creating a line to the

receiving function, we can effectively create a GOOSE message from Q03 to Q04. Once the mouse

button is let go, a signal on the receiving function should be chosen which for this example is an

attribute of GGIO.

Before we verify whether the communication has been implemented correctly or not, we will move on to

the ideal method where an IED is made of specification.

Ideal Method In this method, an IED is made of specification related to the customer meaning that there is no ICD file

available and an ideal IED is created which contains all the logical nodes needed for a specific purpose. In

this example, bay Q05 will be assigned to such IED. An overcurrent function will again be created for this

bay and the communication should be between this bay and Q04. So, the ideal IED should at the very least

contain PTRC and PTOC. To do that, we should go back to System Diagram.

System Diagram (create IED) 27. Back on System Diagram, choose IED from Generic devices tab. Give it any name and connect it to

the switch using IEC 61850 connection.


http://www.fmtp.se/






28. Right click on the newly created IED_1 and choose “Data Model Editor”.

29. In this view, you have access to the contents of the IED. By expanding the names, move to Logical

Device. Here, you can add logical nodes to the IED as you see fit. Choose “new child” and “LN” by

right clicking on the Logical device or right clicking on a logical node and choosing “new sibling” and

“LN”. There, you can choose which logical node to add from a list presented for you. Create PTRC

and PTOC.


http://www.fmtp.se/






30. Now that the logical nodes are added to the IED. Go back to bay Q05. Here a virtual IED needs to be

created along with a new Overcurrent Protection function with proper logical nodes. Functions

need to be assigned to the virtual IED and it should be implemented to the IED created in the

system diagram. PTOC and PTRC should be mapped to the ones created inside the IED and lastly a

trip signal should be chosen for PTRC. All of this can be accomplished using previous steps.

Eventually Q05 should look like the picture below.


http://www.fmtp.se/






Application

31. On Single Line view, create another application and name it “Protection Ideal” with an appID. The

communication here is between Q05 and Q04 where a trip signal from Q05 will be transmitted to a

logical node for the breaker at Q04. The logical node in question is CILO (interlocking) which will

essentially result in changing the status of the breaker. This is for the ideal situation and shows the

difference between this scenario and the practical one.

By using past steps, you should be able to create the message and the communication application

should look like the picture below.

Creating communication Now that both applications have been created; it is time to set SCL communication to implement what has

been designed and verify if it has been designed correctly.

32. On the single line screen, click on the icon on top of the screen which says “set SCL communication

from specification”. You can also choose the one next to it to remove anything created previously

and start fresh. By clicking the icon and closing the popup messages, you can move to the next

step.


http://www.fmtp.se/






33. On the main screen (dashboard), choose

Communication.

Now, you can view information about GOOSE control blocks (gcb), inputs, data sets, etc. to verify your

communication design.

The picture shows that clearly two goose control blocks are made for ABB IED and the created IED. It also

shows which signal or variable is being transmitted along with the target logical node inside the Siemens

IED.


http://www.fmtp.se/






In the end, you can export the SCL file by choosing “export SCD, SSD” and this file can be imported to an IED

set for configuration or just used for analysis of the system.

Moreover, a PDF document can be created using the “Documentation” option to give a detailed report of

single line design, system diagram, communication, etc.

Hopefully this guide managed to help you understand how the standard 61850 is utilized inside Helinks and

more importantly how the standard itself is structured.

Advanced options In this section, which will grow, some advanced techniques that can be used with Helinks to streamline

doing a project from single line diagram design to communication establishment, will be discussed.

Function Library One of the ways that you can streamline the design with Helinks is to use the function library. Every

function which is created either by the software or by the user can be added to the library and later used in

different bays of the same project or even in different workspaces. In an example, you will see functions of

a bay added to the library and later used for a different bay.

For this example, we have a different workspace opened and new substation created which looks like the

picture below. You can change the voltage level to a number relevant to your project.


http://www.fmtp.se/






Add functions to the library

1. Double click on bay Q01 and open the function specification diagram, then create a new function

called Overcurrent.

2. For PTRC, choose the signal “Tr.general[ST]”.

3. One important issue to consider while working with the library is that every function, bay, signal

can be classified for a specific purpose. For example, every bay that is made in a project can be


http://www.fmtp.se/






named after a real bay configuration and it can be used later for other projects that might include a

similar bay.

To understand this concept, move back to the single line diagram, click on bay Q01 and in the

properties menu on the bottom, find “Template” and change it from “Default” to “Incoming Bay”.

Now, after adding the bay to the library, “Incoming Bay” will be available for further use.

4. Go back to the function specification diagram and change the template for the Overcurrent

function from Default to “Overcurrent Function”. If you don’t change anything in the Template, the

default names will be assigned to the functions.


http://www.fmtp.se/






5. Another way to make it easier for elements to be added to the library is to change how each signal

is implemented. For this example, you can click on PTRC and view the signal list which should

include “Tr.general”. In one of the columns called “Text 1”, write down “<bay.name> Trip”.

<bay.name> is obviously a placeholder for the name of the bay that contains this type of signal and

the text afterward is whatever you can choose to write. You can view the changes in the pictures

below.

6. The next step in designing the substation automation would be to create a virtual IED, implement it

to a real one and map logical nodes. However, for this part of the guide, we will skip that step and

just create a virtual IED and assign functions to it without any implementation.


http://www.fmtp.se/






7. Now, right click the mouse button on the Overcurrent function and choose “Add function to

Library”.

Press OK on the window prompt.


http://www.fmtp.se/






As you can see from the picture below, it has been done successfully.

8. On the top of the page, on the tab, choose the icon for “invoke library manager”.

You can see that a function has been created in the library with the same name you made in the Template

of the function.

Moreover, to the right of the screen, you can see to which bay this function belongs and to which voltage

level. The bay is called “Incoming” which you named. The voltage is considered “H” according to the

standard for classifying voltage levels under letters. H for 33 kv.

Using the same method, you can add other functions to the library or you can even go back to the single

line diagram and add the bay to the library by right clicking on the bay and choosing “Add Bay to Library”.


http://www.fmtp.se/






Remember that this library is shared among your workspaces. Also, if you move back to the single line

diagram, you will see that “Incoming Bay” is added to the Bay Type Library.

This can be used later on for your designs. But if you wish to use this bay, it would be better for you to add

the bay to the library also by right clicking on the bay and choosing “Add bay to library”.

Use functions from library 9. By using Incoming Bay or just creating another bay and then adding the same equipment to it and

changing the default template to “Incoming Bay”, create bay Q02 as such.


http://www.fmtp.se/






10. Move on to the function specification diagram for Q02. As you can see from the function section of

the palette on the right side of the screen, the “Overcurrent” function is present.

11. Click on Overcurrent and add it to the canvas. Then you see that the same overcurrent function you

created and added to the library is placed on the canvas along with its logical nodes.


http://www.fmtp.se/






You can now add another IED and assign this function to the IED.

Function library with mapping to IEDs

In the previous section, we added the function to the library without mapping the logical nodes to a real

IED. The reason is that if that is done, then a different IED cannot be used for automatic mapping to the

same function but rather the same IED type should be used. Meaning: if you use one particular IED type for

logical node mapping and then add the functions to the library, they are interconnected.

However, if you have one IED type for your system or multiple bays with the same IED type placed in them,

you can use this part of the guide.

12. Before doing anything in the single line, import the ICD file for the IED you would like. Since you

have more than one IED type, you can either duplicate the same IED you have imported or import

the ICD file again. Then, create a simple network like below.


http://www.fmtp.se/






For this guide, we have two ABB IEDs; one for bay Q01, another for bay Q02.

13. Move back to the function specification diagram for Bay Q01, implement the virtual IED to IED_Q01

and map PTOC and PTRC logical nodes to the ones inside the IED.


http://www.fmtp.se/






14. Now, the logical nodes PTRC and PTOC in the Incoming Bay are mapped to REF615 IED. To add the

function to the library, you need to virtualize the IED. You can do that by right clicking on the IED

and choosing “virtualize” or using the virtualize all IEDs icon on the top.

The icon next to it is to implement the IEDs. After virtualizing, add the Overcurrent function to the

library and overwrite the previous one.

15. Move to the second bay, delete the overcurrent function since it has been changed or you can use

the right click mouse button on it and choose “update from library” and add it again from the

palette. Create a virtual IED and assign the functions to it.

16. Implement the virtual IED to “IED_Q02”. Since the Overcurrent function has been placed from the

library and was mapped to the REF615 IED, the logical nodes should be automatically mapped to

the IED ones.


http://www.fmtp.se/






You can repeat the same process for another similar bay with the same IED type and the same function

placed in it. It should be noted that all the existing functions for the equipment, such as the breaker,

disconnector, etc follow the same rules so you can create one bay with one IED and map all the functions,

then just create another bay in single line and just use the same functions and mapping by using the library.

To refrain from being too complicated, the guide will not delve deeper into these methods but rather it is

encouraged to read the guide, test the methods yourself and explore more comprehensively.

Hope that this guide has piqued your interest in trying new methods and options with this powerful tool.
