600MW火电机组发变组保护装置的现状探析

Analysis on the Current Situation of the Protection Device of the Generator Transformer Unit of 600MW Thermal Power Unit

目前我国运行的火电机组中,600MW及以上容量等级机组逐渐取代300MW等中小容量机组,成为电力系统中的主力,其安全稳定运行,对电网的重要性与日俱增。因此,相应保护装置的安全稳定运行,对电力系统的安全,具有重要的意义。本文针对目前600MW火电机组发变组保护装置的现状进行了分析,对装置运行中存在的问题进行了讨论,并对下一步的发展方向进行了探讨。

Among the thermal power units currently operating in China,600MW and above capacity class units have gradually replaced 300MW and other small and medium capacity units,becoming the main force in the power system,and their safe and stable operation has become increasingly important to the power grid.Therefore,the safe and stable operation of the corresponding protection device is of great significance to the safety of the power system.This paper analyzes the current status of the protection devices of the generator transformer unit of 600MW thermal power units,discusses the problems existing in the operation of the devices,and discusses the next development direction.
