测量阻抗轨迹和阻抗继电器性能的研究

为了精确计算测量阻抗随过渡电阻变化的轨迹，本文利用解析分析的方法对双端系统不同故障类型下送、受端正反向故障时的测量阻抗轨迹进行了详细的计算分析，并以姆欧继电器和四边形特性的距离继电器为例简要分析了其稳态动作行为。本文所得到的测量阻抗随过渡电阻变化的轨迹为分析阻抗继电器的动作行为提供了理论依据，对距离继电器的设计制造部门也具有一定的指导作用。

Research of the Measured Impedance Trajectory and Distance Relay Performance

To exactly acquire measuring impedance trajectory changing with fault resistance, using analytic method, this paper calculates the trajectory of the sending end and the receiving end for a forward or reverse fault in detail in a two-source-system under different fault types, and analyzes the steady state operating performance of Mho relay and distance relay with quadrangular characteristic. The measuring impedance trajectory changing with fault resistance can be regarded as theoretical basis for analyzing the operating performance of impedance relay.
