浅谈柴河水电站直流系统的改造

Brief Discussion on DC System Rebuild of Chaihe Hydropower Station

蓄电池直流操作电源是一种独立的电源,它与电力系统的运行方式无关,在出现电网事故的情况下,它依然可以对继电保护、自动装置和事故照明设施供电,因此,具有很高的供电可靠性。直流系统的稳定,关系到整个电站的安全运行。柴河水电站在2015年的增效扩容改造中更换了直流系统,消除了之前直流系统由于年久超负荷运行所带来的安全隐患,保证柴河电站的安全稳定运行。

Battery DC operational power supply is an independent power supply.It has nothing to do with the operation mode of the power system.It can still provide power for relay protection, automatic devices and emergency lighting facilities in the case of grid accidents.Therefore, it has high reliability of power supply.The stability of DC system is related to the operation of the whole power station.Chaihe Power Station replaced DC system during the efficiency and capacity expansion improvement in 2015, thereby eliminating the potential safety hazards caused by the overload operation of DC system in the past, and ensuring safe and stable operation of Chaihe power station.
