蓄能电厂静止变频启动装置启动失败问题研究

Starting failure of static frequency converter for pumped-storage power stations

随着现代大电网的不断发展,大型抽水蓄能电厂以其快速、有效、经济、可靠的特点,在电网的调峰填谷中扮演着重要的角色。抽水蓄能机组一般采用静止变频器作为启动设备,具有启动速度快、启动容量大、工作可靠性高、维护工作量小等优点。本文试分析惠州蓄能水电厂A厂机组投产初期,频繁出现静止变频器启动失败的原因,并提出解决方案。

With the continuous development of large modem power grids, large-scale pumped storage power stations with the characteristics of high effciency, economy and reliability play an important role in adjusting grids peak and valley load. Static frequency converter （SFC） is generally used aa a boot device on pumped storage units, with the advantages of a launch speed and capacity, high operational reliability and small maintenance workload. This paper analyzes the cause of frequent starting failure of static frequency converter during the early operation and proposes corresponding solutions.
