Research And Development On Simulation Training System Of Relay Protection For The Hydropower

Simulation Training System of relay protection for the Hydropower just is developed for the relay protection work staff who was engaged in the Hydropower, trains them the ability of rapid judgment and troubleshooting according to alarm information and equipment movement situation, as well as familiar with relay protection principle and operation flow of the relay protection device.This paper introduces a power system protection simulation model based on logic judging method and presents a visual simulation software architecture, completed the development of Simulation Training System of relay protection for the Hydropower. Graphic model of electric power equipment is developed by Visual graphic 7.0 integrated environments. This method improves the development efficiency of Simulation Training System of relay protection for the Hydropower, and makes the processing of development focus on the simulation model of relay protection device and the method of simulation training. Aimed at various of protecting type, protection principle of relay protection device complex caused by simulating the complex problems, based on the relay protection principle and relay protection device results, this paper designed the protective device general simulation model. Protecting universal model can well realize line protection, bus-bar protection, circuit breaker protection, transformer protection, generator protection and other electric equipment protection simulation. Meanwhile, in the past, the relay protection device simulation model form the breaker tripped information table by manual, the modeling method not only trivial, but also still not flexible, this paper brings forward a new methods by using of electric network topology analysis information to automatically form breaker tripped information table, this method can process power grid structure changes, and the modeling method can face different main electrical wiring of hydropower station. The ideas and methods of paper already successfully applied in the simulation training system of relay protection for the Hydropower.The relay protection simulation training system is developed by the object-oriented language Delphi2007 under the Windows platform, and combines Access 2007 to manage the large data information of simulation training process. Through the application of hydropower project"Simulation Training System of relay protection for the Hydropower"essay that the relay protection simulation training system has a certain practical.
