Operator Training Simulator (OTS) logics development using LUA programming language scripts
September 20, 2016
In recent decades, many studies have been developed about operator training systems. Many of these systems, called OTS (Operator Training Simulator) simulate the operating environment of one or more substations. This study aimed to modernize the training standards in order to obtain better results in the operation of the Electric Power System.
Using the simulator, the operator can perform a variety of activities from their daily duties, through a friendly interface that is as close as possible to the operating environment of a substation, from the location of the field equipment, as well as control room panels, existing controls and protections. The graphical interface was developed in HTML and SVG languages, and with the use of JavaScript in scripts, it was possible to establish an interface between web servers and viewers. Like most substations often undergo improvements and / or expansions, it becomes very laborious to remake or adapt the simulation systems. One of the ways found to facilitate the adequacy is through scripts that perform control functions and protection of the installation. So in this simulator, we developed a script in Lua language. Lua is a powerful programming language, fast and light, designed to extend applications. It is used for logical, operators, scenario generation, protection and control and also in supervisory systems and computer games.
The script file “script.lua” is loaded and executed automatically by the web server during startup. Within this script should be a function “ScriptCycle” defined by the user, which will be called periodically while the “Webserver.exe” is running. Some APIs (Application Programming Interface) provided by the server are, for example, “hmi_write_point”. Functions have also been developed, such as automatic tap control for voltage regulation and logic for interlocking switches and circuit breakers.
Using this methodology, changes in the system database are not necessary (SCADA or HMI), not compromising the operation of the installation.

OSHMI – Open Substation HMI
November 5, 2015
Here is the link for the HMI software https://sourceforge.net/projects/oshmiopensubstationhmi/ It’s a third release candidate, not fully tested, but I think it’s very usable. Some things might change until the official 3.0 release. The source code is available via a Mercurial repository. Simply download, install and follow the instructions present in c:\oshmi\release_notes.txt. Have fun!
Process Bus
November 2, 2015
In recent years in Brazil, some companies are testing a new solution for substation automation. The bus processes has as objectives reduzier costs and improve system performance. Some equipment had unwanted behavior, requiring some review process, with updates and review of safeguards. Despite these percausos, the result so far has been satisfactory.
OTS in Workshop

OTS – Operator Training Simulator
January 15, 2015
Operator Training Simulator (OTS) is a computer-based training system that uses a dynamic simulation to play an substation environment. Usually integrated with an emulator of the process Distributed Control System (DCS).
This type of software is a tool used in classrooms for training of a substation functionality, and can be used for training at distances. This simulator has a graphical interface developed in HTML and SVG language. Through the use of scripts is possible to establish an interface between servers and viewers.

OSOTS – Screens
November 12, 2014
The OS-OTS (Operator Training Simulator Open System) provides the following screens:
- Simulator, which is the main interface of the program, where the panels are available for manipulation.
- Substation: where are represented the equipments present in a power substation.
- Instructor (New): module for monitoring the activities and scenario generation.
Soon more information.
