并评估相应运行风险。仿真结果表明

基于全过程的自动校核方法能够较为真实地反映实际电力系统发生故障后的动态过程

更好地发现由于保护和限制定值缺陷导致的问题

实现优化控制对象

为电网的安全运行分析和决策提供支撑。

Abstract

The generators’ grid related protections and limitations do have some problems

such as the conservatism and mismatching of settings of protections and limitations

and the coordination between these protections and limitations and power systems. Based on full dynamic simulation

an automatic checking method of generators’ grid related protections and limitations is proposed. It can be used to check the dynamic performance of protections and limitations of generators in different fault operation modes to evaluate the operation risk of power system. Simulation results show that the method is able to reflect the dynamic performance of electric power system after a fault more realistically. It can be an effective tool for the stability analysis and optimization control of power systems.This work is supported by State Grid Corporation of China (No. XTB1120136s640).
