Research of Single-Device Test Based on Relay Protection Simulation and Training System

This article put forward a Single-device test method based on the protection Tester and the relay simulation training system, and it takes advantage of the board as a real-time source, network sampling value message and GOOSE Subscribe publish using of Visual C + + programming language, which acts on the simulation of the actual protection device, the dynamic display logic process and the secondary circuit protection action signal and it is with the actual logic of the protection device. This article discusses the design of the simulation system, as well as virtual protection principle library brief simulation, the software uses a flexible, simulation results are accurate and reliable, clear and intuitive. It is available relay operating personnel training, so that by the trainees can go deep into protection device internal device deep principle.

The Interactive Display Design Tool: An Application Program for Part-Task Simulation Development

Traditionally, part-task simulation development has involved large amounts of time and effort. This was due to: 1) the inherent complexity of designing real-time software; 2) difficulty of converting dea/concept into specific software engineering requirements/specifications; 3) the need for extensive interconnected computer systems (both graphical and non-graphical). There are 3 activities involved in the creation of a part-task simulation: 1) the physical display format; 2) the definition of the input (Simulation Logic); 3) the definition of the response to the inputs (Display Logic). The Interactive Display Design Tool (IDDT) was a concerted effort to allow parts of the external interface to be created directly by interface designers, rather than software engineers. The original version of IDDT allowed the designer to interactively create and modify display formats. The current capability of IDDT allows interface designers to partially create and modify display and simulation logic. This paper discusses the specific methodology used within IDDT: display lists and look-up tables, and cites examples and capabilities of the tool. In conclusion, specific instances of significant savings in time and effort required for part-task simulation creation are given.
