结合锦屏二级水电站水轮发电机的特性,通过对水轮发电机全面的内部短路分析计算、定量化的设计过程,完成了主保护配置方案的设计,保护方案性能优异。实现了水轮发电机保护无动作死区,而且对所有实际可能发生的内部故障有2种及以上不同原理的主保护灵敏动作,为大型水电站水轮发电机的安全运行提供了可靠保证。
Combined with the hydroelectric generator’s characteristics of Jinping II Hydropower Station, the design of the main protection configuration scheme is completed by the comprehensive internal short circuit analysis and calculation of the hydroelectric generator and the quantitative design process, and the performance of the protection scheme is excellent. The dead zone for the protection of hydroelectric generator is achieved, and the main protection sensitivity action of two or more different principles for all internal faults that may actually occur provides a reliable guarantee for the safe operation of the hydroelectric generator of a large hydropower station.
