摘　　要：介绍了隐极与凸极机组过电压保护、失磁保护等涉及网源协调运行的保护装置功能判据与整定配合,并针对其涉网保护出口方式、保护判据及整定配合等差异性进行详细分析,采用全过程仿真程序实施凸极机组失磁保护综合判据典型方案的案例仿真,研究了失磁保护与低励限制配合方法并进行实例验证。It was introduced that overvoltage protection,loss excitation protection of non-salient and salient pole synchronous machines relates to protective devices of network source coordinated operation for function and setting criterion. It was also analyzed in detail with difference among tripping way,protection criterion and setting coordination.Moreover,it was adopted as full dynamic simulation program to implement case simulation of the typical scheme of the comprehensive criterion for loss excitation protection. It was also carried out and verified of research on the coordination methods between loss excitation protection and low excitation.
