摘要(Abstract):
结合嘉兴发电厂二期工程的实际情况,讨论了大型发电机组非全相保护配置的必要性和重要性。对发电机非全相保护与线路重合闸、断路器本体三相不一致保护配合的相关问题做了进一步分析,指出发电机非全相保护存在的问题,并提出了改进建议。
According to the instances of Jiaxing power plant, the article discusses the necessity and importance of incomplete phase protection. Some problems are analyzed, such as reclosing of incomplete phase protection with line, and three-phase discrepancy of breakers. Then suggestions are put forward to solve these problems.
