摘　　要：针对现行距离保护动作性能的影响因素,利用PSCAD所搭建的仿真模型,研究分析了南瑞继保公司PCS-901系列产品距离继电器在过渡电阻和串补电容影响下的动作特性。研究结果对改善该系列产品距离保护动作性能具有指导意义,并对高压输电线路上保护的配置和应用具有参考作用。Aiming at the influence of the transition resistance and series capacitor compensation on the operating characteristics of current distance protection,a simulation model by PSCAD is built to make a simulation analysis about the Nari-Relays PCS-901 series products affected by various factors,based on the principle of distance relay of PCS-901 series products.The research results deepen the understanding of operating characteristics for commonly used relay protection and have referenced value to the configuration and application of relay protections in the high-voltage transmission lines.
