Brazilian Electrical Power System

13th International EPCC Workshop Bled, Slovenia, May 2015

OTS in Brazil

-Many companies are using systems for operatortraining;-Some companies have a dedicated training room;-Interface: panels or diagrams;-Focus: substation operator training and systemdispatcher;-Developed for electrical system transmission.



OTS

-Training-Certification-Recycling

-Created a model of Substation for simulation:*1 power transformer of 330/145 KV*1 transmission line of 330 kV*2 transmission line of 145 KV

-Uses an open source system.

Data Base

- Point list- Point Calc

The graphic interface (drawing) was developed in SVG language.


Graphic Interface

-Screen Viewer-Alarms Viewer-Events Viewer-Historical-Others



Data Base

-Point List: Substation point list. Example:*State of circuit breakers and switches*Measures*Commands*Protection events

-Calc List:Calculations for active power, reactive power, apparent power, and others.



Lua Script



Lua

-Lua was created at a Brazilian University.-Lua is a Languagem for games and automation applications; -Create many functions for control or devices; -Create functions for interlocking, lockout relay control, tap control; -Create a script in Lua Language for application;



Functions

-Processing Module (3 Keys);-Interlocking Switch;-Interlocking Circuit Breaker;-Processing Module Transformer;-Lockout relay(Bar and Transformer);-Others.



Example

-Interlocking Switch

-Seven entries: *State switch (this case 28)*State circuit-breaker (24-1 and 4)*State key local/remote 28*State of other switches*Switch alarms

-Result: the locking or unlocking of the switch command.



Example


OR

Switch 28: Command unlocking!


?

Example

-Interlocking Switch



Objective


SCADA/HMI OTS/DTS

Results

-High performance of the developed logic in LuaLanguage;-Easy to create new logics and controls;-Simplified expansion of the substation;-Software Reuse.

Problem in power flow: instability of measures.

Focus: solutions for power flow, create a logical controlfor protection transfer and others, new arrangements,simulation application in company.
