基于IEC 61850的继电保护单装置测试仿真方法

his article put forword a new method of relay protection single device test simulation based IEC61850, it uses the Visual C++ programming language to take advantage of the board as a real-time source, network sampling value message and GOOSE Subscribe publish ,which acts on the simulation of the actual protection device to dynamic display the logic process and the coordination of secondary circuit protection action signal and the actual logic of the protection device. This article discusses the design of the simulation system of single device test, 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.
