摘　　要：随着电力系统大容量机组不断投入运行,对电气主设备保护提出了更高要求。对发电机内部故障主保护、定子绕组一点接地保护、转子绕组接地保护、变压器差动保护等研究热点问题进行了讨论,提出了主设备保护未来发展所需要做的重点研究工作。Along with many large - sized generators continuously going into operation in the power system, the requirements on protection for electric main equipments become more and more high. The research hotspots , such as main protection for generator internal faults, one point earth - fault protection for generator stator, rotor grounding fault protection and transformer differential protection, have been discussed in the thesis. In addition, the main study needed in the future development of electric main equipment protections also has been pointed out.
