Architecture (1) Architecture (2)

Summary of main NM advantages for the end users (1)

One centralized db/server <> several independent db/servers

• All users can use the same displays, will see and share the full system acquired, computed or substituted information + notes/tags/..

• Harmonization of DB & business rules becomes a constraint but :

It will improve the quality of database/procedures It will make operators more interchangeable

• A user can work from any console (even remotely), what he will see or can do depends only from its own DB user rights.

• All users will share the same set of historical data & logbook (one common DWH db)

• Backup system for national control center is fully synchronized/consistent with Master system

All functional units (EMS, DWH, ELCOM/TASE2, PCU’s…) are redundant X 4 (Online/standby/synchronized/synchronized)

• robustness & availability increased

PAS, SCADA, DTS functions integrated in the same system (one common database)

• Same GUI tool (WS500) for using these functions• Same process displays (station/flow schemes, …) are

used to support these functions• Database always consistent between SCADA/PAS

(common network model)• No longer ELCOM link in between with risk of failure Test system available (with real time link) to test a

new DB before putting it into production (step included in DB population work flow)

A real Datawarehouse (UDW) with more reporting possibilities and interfaces developements perspectives (rich API’s library)

One replicated SCADA & DWH server + Web server • IS500 SCADA (limited) GUI application available on

intranet (with several functional improvements <> old WCS)

User interface (1) User interface (2)


Set of std ABB displays (NMTAB) for displaying input and output data with functions such like AGC,PAS,ELCOM/TASE2,Control system,…) very detailed

Navigation in WS500 : Value select feature (display scada or PAS values) Zoom/layers/delcuttering functions are supported Overview window supported in zoom mode Advanced locate feature Dynamic functions keys Usefull Point information window (with up to 5

external keys available for each SCADA/PAS ID) Possible to apply different contexts (time select, DNC

mode, value select mode,..) in separated windows Possible to navigate through intranet WEB pages Possible to call an external application from a WS500

menu Possible to put a BMP/JPG in background of a

WS500 display. Auto filter of E&A lists based on navigation

Modern Look & feel of WS500 (GUI). WS500 is working under windows PC’s : Easier to exchange data with local PC (copy/past, save

file, export, …) Same navigation principles as in standard MDI windows

applications (minimize/maximize/… ) Possible to customize all toolbars/menus for the user Up to 6 24’ screens for an operator Powerfull tool “authority explorer” to manage user

rights for defining allowed operator actions and contents of event & alarms lists :

High granularity of allowed actions in WS500 Thousands of subsystems available (not only 9 zones !)

to define areas of responsabilities Possible to supervise and transfer roles between

operators Possible to define “MUST” roles Grid component “NMTAB” used in all tabular displays

(PAS, SCADA status lists, AGC, Control system, User defined displays….) very user friendly (sorting/filtering/exporting features…)

SCADA functions (1) SCADA functions (2)


Dynamic Network Coloring function• color equipments in process displays depending on the

current topology/energized state and according to different optional criteria (Node, voltage level, subsystem, island, …coulouring )

Limits management• Up to 5 levels of SCADA limits• Limit manager function can update dynamically SCADA

(& PAS) limit values (according to seasons, time or TM signal)

• Possibility to activate or deactivate the supervision of limits thresholds

Event & alarm processing More possibilities to categorize events/alarms (based

on point class, reason criteria, priorities concepts) and therefore more flexibility to :

to filter/extract them afterwards To define alarm summary lists

Rate of change/gradients limits Mobile alarm function (function sending sms/mails

automatically or manually)

Historical data (trending/time select/post

disturbance review/..)• No limit on historical period (up to 5 years)• Accuracy of 1s (by default) for all

measurands/indications • Play back function supported• Default trending (without need of any engineering) for

for all points available in WS500 display. SX reports • Possibility to define & use XLS reports refreshed with

RT and/or UDW data. Calculation• More flexibility (advanced programming language)

to define calculations (SPL)• User defined online ARTC (Matlab) calculations (based

on UDW or RT data)• Composite objets supported. • Generic interlock rules• Std Equipments statistics counters• Advanced ELIA station global indicators

SCADA functions (3) SCADA functions (4)


Operator actions• Sequence control supported • Edit tags & symbol operator notes (& notebook?)• Comments events• Define online and share with other users :

Filters to be applied to event/alarm lists Status lists

Possible to send several commands in // on objets related to the same PU

Apply button supported for commands Expiration delay supported for blocking actions Alarm Lists features Possible to color alarm records according to

categories& priorities of events Possible to see/distinguish “partially” acknowledged

alarms Alarm summary lists indicators in tool bars Communication with external partners

TASE2 protocol ssupporting controls/setpoints +

Acquisition• Feed back supervision on set point and incremental

controls• State change Jitter quality flag for indications AGC/ITS :• Fully standard tool <> customized calculations into

old SCADA field proven and more reliable.(TBC)• Set of standard displays very detailed• Design of std AGC function offers a lot of nice user

features, (difficult to be exhaustive) • Prodplan and ITS standard user interfaces (integrated

with WS500) allows the operator to navigate (and overwrite) scheduled data coming from Nxpro & Prores applications

• Full archiving into UDW of all relevant variables involved into AGC regulation mechanism. All these archive data available in trends/sxreports/….

PAS functions (1) PAS functions (2)


Real time sequence (NAC) : • Event triggered real time sequence• Validity time of output related to each EMS

application BTD : new function to identify suspected bad

measurands SE improvements: • 2 levels of limits for violations (75% & 100%) in line

with SCADA limits. (= project config)• In case of violations, “Orange” and “Red” colors are

presented on 1-L diagramas and in violation output displays

• In output displays, possible to see violations related to each control centers or to full ELIA network

• Beter performances SA improvements: • Possible to define load/unit rescheduling into outage

definition• Possible to define Remedial action schemes• User friendly SA dialog to edit online contingencies

• Automatic “propagation” of contingencies (propagation stops when a breaker is found) in line with new UCTE rules

• In case of violations, “Red” colors are presented in violation output displays

• In output displays, possible to see combined severities related to each control center or to full ELIA network

• Output display exists to show for each monitored equipment the sublist of contingencies that puts this equipement in violation.

• Beter performances SCA improvements: • Possible to simulate unbalanced faults (if data are

provided)• Possible to simulate line faults• Possible to have full post incident electrical state

presented in output display or on 1-L diagram for one specified fault

• Possible to have all bus CC results displayed at the same time on the 1-L diagrams

• Violations are on breakers (and not on buses)

LF save case (automatic SE savecases or manaul DPF save cases)

CIM/NSI file NPU database (based on a study date) (rem :

Equipment Outage scheduling function supported) Beter performances DPF : • LF comparison feature (DPF solution <> savecase)• 2 PAS limits (75% & 100%) with orange/red colors

presented in 1_L diagrams and in violation displays in case of violations

Possible to update DTS database very easely from RT (no longer need of several weeks of engineering work !)

Closed loop with AGC supported All types of relays can toggle an alarm indication into

SCADA when triggered Dedicated DWH for DTS (to support

trending/reporting,..) Possible to define in DTS MMI what are the variables to

be recorderd by FAST (for trending after the simulation) Some new improvements into the User interface (i.e

library of DTS base cases available in WS500)

Product evoluates due to other customer requests. Same SLA for PAS and for SCADA (support 24 X 7)
