火电机组甩50%负荷试验操作浅析

Analysis on Operation of 50%Load Rejection Test of Thermal Power Unit

对于火电机组甩负荷试验,高压旁路控制是一个重点。实例呈现未设置快开保护功能的小容量启动旁路如何手动控制旁路开度,该做哪些准备,以完成机组甩50%负荷试验。同时,阐述甩50%负荷试验前及试验中的注意事项,以期为同类型启动旁路机组甩负荷试验提供参考。

High-voltage bypass control is a key point in load rejection test of thermal power units.This paper presented an ex-ample of how to manually control the bypass opening of small capacity start-up bypass without quick opening protection function,and what preparations should be made to complete the 50%load rejection test of the unit.At the same time,the matters needing attention before and during the 50%load rejection test were described.It can be used as a reference for load rejection test of the same type of start-up bypass units.
