Brazilian Electrical Power System

13th International EPCC Workshop Bled, Slovenia, May 2015

OTS in Brazil

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



-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.

Graphic Interface

-Point List: Substation point list. Example: *Digital States of circuit breakers and switches *Measures *Commands *Protection events -Calc List: Calculations for active power, reactive power, apparent power, and others.



Data Base



LUA Script

-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;



LUA

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



Functions

-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!

Objective

-High performance of the developed logic in Lua Language; -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 control for protection transfer and others, new arrangements, simulation application in company.
