300MW机组阀切换负荷波动原因分析

Analysis on the Cause of Great Load Fluctuation of Valve Switchover

针对300MW机组DEH系统阀门切换时出现负荷大幅度波动的现象,从流量特性曲线、运行方式等方面进行分析并提出解决问题的方法。

The writer analyses the wide fluctuation of the load when the valve of DEF system in 300MW unit switch over from the aspects of flow characteristic curves and the operation methods. Meanwhile the solutions are proposed by him.
