西霞院水电站机组备用水源变频器控制系统改造

Improvement of Inverter Control System for Standby Water Source of Xixiayuan Hydropower Station

西霞院电站4台机组共用一套备用水源系统,机组技术供水系统使用备用水源供水方式时,主要依靠3台备用水源泵提供动力水源,采用变频器控制方式有效避免各台机组供水量和供水压力不均衡问题,并且节约大量厂用电,有利于技术供水系统的安全稳定运行。

Four units of Xixiayuan power station share a set of standby water source system.When the technical water supply system of the unit uses the standby water source water supply mode,it mainly relies on three standby water source pumps to provide the power water source.Adopting the frequency converter control mode can effectively avoid the imbalance of water supply quantity and water supply pressure of each unit,and save a lot of plant power,which is conducive to the safety of the technical water supply system Stable operation.
