3. SCADA/DMS system integrations with other existing SCADA and IT

system

As explained in the section 8 there are different IT/ERP and SCADA/DMS systems existing in utility.

The proposed solution has to share data with these applications. Opportunities of utilizing the

existing or planned infrastructures of the Utility shall be explored and utilized during implementation

of SCADA/DMS system. Space is available at the Baroda city (MGVCL) existing control room for

installing new SCADA/DMS system. Suitability of these spaces along with other requirements of

power supply, cooling, lighting etc. shall be studied by SIA before proposing the utilization to Utility.



3.1. Existing SCADA/DMS integrations at MGVCL

Existing SCADA/DMS System at Baroda City need to be integrated seamlessly with proposed R-

APDRP system ensuring maximum utilization of available resources at substations as well as control

centre . Best possible options assumed are given below for assisting the SIA, but SIA has to design

the correct integration solution broadly in line with the suggested option according the their proposed

system. However deviations are limited and the purchaser reserves the right to accept or reject the

integration solution proposed by the SIA during technical evaluation. Any additional hardware or

software required for this integration shall be purchased by the bidder.

3.1.1. Integration Option

There are 15 numbers of Substation RTUs and 21 numbers of FRTUs presently connected to the

existing Siemens make SINAUT Spectrum SCADA/DMS. These are communicating with the

control center in IEC 60870-5-104 protocol. Redundant communication server interface the RTUs

and FRTUs with the SCADA/DMS servers. Successful bidder shall integrate the existing system with

the new R-APDRP control center to extend all functionalities to the existing locations of the network.

A suggested integration method is given below:

Establish connectivity between Communication FEP servers of new R-

APDRP SCADA/DMS with the existing communication servers. Real time data communication

between the systems shall be established using any standard protocol for achieving read and write

functions from the R-APDRP system to the existing 15 RTUs and 21 FRTUs. Any hardware/software

addition required for the communication between the systems shall be done by the bidder. Selection

of protocol and overall integration shall be done in such a way that all performance and functional

requirements of the complete system are achieved as specified in the MTS. Suggested integration

architecture is given in Appendix B for the reference. Successful bidder has to execute any upgrade

or modifications required in the existing RTU /FRTU hardware/software to ensure that all signals are

connected to the RTU or FRTU for fulfilling all the DMS function as per the MTS. The exiting

SCADA/DMS signal list is given in the Appendix-A.

3.2. Integration with R-APRDP IT System

SCADA/DMS system shall exchange data with IT system using CIM/XML and IEC 61968 series of

standards. The system shall utilize an IEC 61968 and IEC 61970 compliant interface. The system

shall enable export of all data via a CIM-XML interface and shall utilize modeling from IEC 61968

as appropriate. This data exchange shall be done using SOA/ESB Enterprise Services Bus already

provided by ITIA, over Open XML Models defined by CIM/XML.

Data exchange between IT system and SCADA/DMS shall be over model neutral messaging services

and CIM/XML model based data exchange for real-time or historical data will be used. The following

standards as applicable will be used to achieve the above requirements: Messaging interfaces shall be

based on model neutral interfaces based on the IEC 61970-40X series for access to real-time and

historical data and use the IEC 61968-3 and IEC 61968-9 standards for messaging interfaces that are

model dependent for network operations and metering respectively. More over implementation shall

be based on the EPRI specification document, “Enterprise Service Bus Implementation profile

(1018795)”, which defines the implementation profile for IEC 61968 using technologies commonly

found on an Enterprise Service Bus.

Any non IEC-61968-1compliant interface part of the adapter may be interacting with SCADA/DMS

over:



� ICCP

� OPC

� ODBC

Min data exchanges are

• GIS data exchange between IT and SCADA/DMS

The GIS survey of the entire city distribution is conducted and saved as a part of IT

implementation. The updated GIS data is available in the IT GIS server. The same GIS data is

using for the SCADA/DMS application. The data exchange shall be in a common modem

(CIM-XML) data exchange format. The coding using for each distribution asset should be

same in all the application (IT, ERP, SCADA/DMS) in order to avoid the use of adaptors for

exchanging the data

• Breaker status data exchange

All the substation /RMU Breaker status, Tripping details, Tripping time and date will be

available in the Breaker status table associated with the SCADA/DMS application database.

This data has to exchange with the Customer care system of the IT part. This will be on

demand or by exception exchange. This information exchange also is in a common model

format like CIM.

• Daily Energy data.

The daily energy data of each feeder shall be stored in the SCADA/DMS database. This data

will be shared with the billing system of IT part. This Exchange will be on demand or by

daily.

• Load Priority table The SCADA/DMS have load feeder data containing Breaker name, number of consumers

connected to each breaker and load priority .This database will be shared by IT and

SCADA/DMS. The load priority information will be updated by the SCADA/DMS and

consumer data will be updated by the IT

3.3. Integration with SLDC System

Integration with State Load Dispatch centre (SLDC) for the state for exchanging relevant real time

data & scheduling data over ICCP shall be done by SIA. The data which has to be shared with SLDC

will be giving by the Utility at the time of implementation .Data requirement and bilateral agreement

with SLDC shall be done by the utility. SIA shall demonstrate the data integration to both owners of

SLDC and each DISCOM for approval of the function. Any hardware or software requirement shall

be met by the SIA.
