摘要
提出了燃气轮发电机启动期间相间故障、定子接地、过激磁以及静止变频器直流接地故障的保护原理和算法,简单讨论了它们的整定计算问题,并对启动期间定子接地和主变差动保护的方案提出了改进措施。
This paper presents the protection principles and algorithms for phase-to-phase fault, stator winding grounding fault, over-excitation and DC grounding fault of SFC during starting-up of gas turbine generator. The problems of setting value calculation for these protections are simply discussed. Simultaneously, this paper brings forwards the improvement measures for stator winding grounding protection and differential protection of main transformer during starting-up of gas turbine generator.
