摘要
1 000 MW发电机组电压等级高、容量大,其继电保护受到非常多的关注.提出大机组保护的配置方案以及可能面临的问题,分析保护的容错原理和技术,介绍失磁保护、定子接地保护及转子接地保护的选型要求,认为保护装置硬件系统的冗余度是确保1 000 MW机组安全经济运行的重要措施.
The 1 000 MW generator has high voltage and large capacity, and its protections are paid much attention. The configuration and possible problems for the protection are proposed in this paper. The fault-tolerant principle and technology for the protection are analyzed, and the requirement of types selection for loss-of-excitation protections, stator ground protections and the rotor grounding protections are introduced. It is believed that the redundancy design of the protection hardware system is an important factor to ensure safety and economic operation of the 1 000 MW unit.
