Modeling and simulation analysis of relay protection based on DIgSILENT

DIgSILENT (Digital Simulation of Electrical Networks)是一款专门用于电力系统的集成分析软件,继电保护仿真功能是该软件众多功能中的一项辅助功能。电力系统故障仿真可有效预判大面积的停电事故,能够最大程度的降低风险,提高电力系统运行的可靠性和安全性。以过流保护、双电源保护和距离保护为例,介绍了DIgSILENT平台下继电保护建模原理和具体过程,并通过仿真验证了该平台上进行继电保护仿真的有效性。

DIGSILENT (Digital Simulation of Electrical Networks) is an integrated analysis software for power systems in which Relay protection simulation is an auxiliary function. Power system fault simulation can effectively predict large-scale power outage accidents, and thus minimize risks and improve the reliability and safety of power system operation. In this paper, the overcurrent protection, dual power protection and distance protection are taken as examples. The principle and specific process of relay protection modeling under DIgSILENT platform are introduced. The effectiveness of relay protection simulation on the platform is verified by simulation.
