摘　　要：针对电力保护和控制系统模型难以准确体现继电保护动作逻辑而导致模拟连锁故障困难的问题,阐述了基于继电保护和安自装置UD建模的连锁故障仿真分析方法,建立了继电保护和安自装置模型,在PSASP中进行了连锁故障仿真计算。仿真实例分析结果表明,基于继电保护UD建模的连锁故障仿真分析方法能够真实反映继电保护动作逻辑和电力系统全过程动态行为,实现连锁故障的仿真分析。Electric power protection and control system model fail to accurately present the action logic of relay protection, chain failures, therefore, are difficult to simulate. This paper introduces the simulation analysis of chain failures based on relay protection and security automatic equipment UD modeling, establishes relay protection and security automatic equipment model and carries out simulation calculation of chain failures in PSASP. Simulation results show that the simulation analysis of chain failures based on relay protection UD modeling reflects the real action logic of relay protection and dynamic action of electric power system and realizes the simulation analysis of chain failures.
