珠江电厂 300MW 机组锅炉给水控制系统

Boiler feeder water control system for 300MW unit of Zhujiang electric power plant

本文通过对珠江电厂锅炉给水控制系统进行原理分析，可靠性论证，现场影响因素探讨，提出了要保证该系统长期稳定处于自动方式运行，对运行操作和检修维护的工作的必要要求。同时对大容量、高参数机组中采用调节级后压力来测量主蒸汽流量的方法，即Ｑ＝ｆ（Ｐ１）关系进行了讨论。

On basis of principle analysis,reliability demonstration,on-spot affecting factors of boiler water supply control system in Zhujiang electric power plant,this article puts forward necessary requirements to ensure the system in state of long-term stable automatic operation and maintenance to the system.It also makes discussion on Q=f(P 1)——measuring main steam flow with adjusting post-level pressure in large capacity,high value parameters units.
