摘　　要：本文结合发电厂发变组保护的整定计算导则,分析发电机基波零序电压保护、断路器闪络保护、主变差动保护以及主变后备保护在整定计算中容易出现的问题;结合工程实际,提出了在工程中可能实现的解决方案;通过某典型火电厂发变组实际参数进行计算,验证了方案的正确性。Based on setting calculation principle of generator-transformer protection, possible problems in setting calculation of zero sequence voltage protection, breaker flashover protection, main transformer differential protection and main transformer backup protection are analyzed. Combine with engineering practice, a feasible solution is proposed, then the correctness of this solution is verified by anactual parameters of a certain power plant.
