摘要

文章对调相机和发电机的继电保护配置方案进行了对比分析

并结合调相机的启动方式分析了该过程对主保护的影响。最后建立单机无穷大系统仿真模型

分别对发电机和调相机的失磁故障动态过程和测量阻抗轨迹进行了仿真计算

讨论了失磁保护采用阻抗判据的可行性。

Abstract

The relay protection schemes of synchronous condenser and generator are compared and the differences are discussed. The influence of start-up process on main protection is analyzed combined with the start-up pattern. At last

singlemachine infinite system model is set up

the dynamic process and measurement impedance locus of loss of field fault is simulated and calculated. The feasibility of applying impedance criteria to loss of field protection is discussed.
