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.

Lua Script
13th International EPCC Workshop Bled, Slovenia, May 2015
Operator Training Simulator (OTS) logic development using LUA programming language scripts
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;

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.

Operator Training Simulator (OTS) logic development using LUA programming language scripts
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.
