比相式阻抗继电器工作仿真研究

Operating Performance Simulation of Phase-Comparison Impedance Relay

采用MATLAB2016的仿真部分对比相式阻抗继电器的工作原理进行了仿真。距离保护是输电线路主保护之一,广泛应用于110 k V及以上的输电线路上。阻抗继电器是距离保护的测量元件,其工作特性决定了保护的工作原理和决定了保护整体的性能。该研究的目的就是研究比相式继电器的基本工作特性,以及它在各种工况情况下的工作情况,验证其基本工作原理,为分析保护性能提供理论依据和仿真数据。

The operating principle simulation of the phase-comparison impedance relay is carried out in this paper with MATLAB2016. The distance protection,one of the main protections of transmission lines,is widely used in 110 kV and above transmission lines. As the distance protection measuring element,the performance characteristic of the impedance relay determines the working principle and the overall performance of the protection. The purpose of this paper is to provide theoretical basis and simulation data for protection performance analysis by studying the basic characteristics of the relay and its performance under various working conditions to verify its basic working principle.
