摘要
Abstract
The configuration and design of generator-transformer unit relay protection in Pushihe Pump-storage Power Station is introduced herein. The relay protection has characteristics of two sets of protection system stand-by to each other, more reliable software switching, and independent operation without relying on monitoring system. For solving the problems discovered in the commissioning tests, the breaker tripping scheme during back-to-back starting process is optimized, the rotor one-point grounding protection equipment is re-selected, the right operation of stator grounding protection is analysed, and the copper grounding to unit control and protection board is also added. Hie experiences of commissioning tests can be as references to other pumped-storage power stations.关键词
