摘要

针对仿真程序中继电保护模型的研究现状进行了综述，提出了继电保护模型的建模方法，进而构建了一个用于电网稳定计算的继电保护模型接口仿真平台。在PSASP中引入了距离保护模型，进行了暂态稳定仿真计算，仿真结果如实描述了线路后备保护的动作特性，表明引入继电保护模型能更真实地反映实际电力系统受扰动后的动态行为。

Abstract

By summarizing the development of relay protection model in power system simulation， the modeling method of relay protection is discussed. Furthermore， a simulation platform for relay protection model interfacing with power system stability calculation is developed. A distance protection model is introduced in PSASP and the transient stability simulation is completed. The results show that the simulation including relay model can describe the dynamic behaviour of power system after disturbance more factually than that without relay model.
