热电联产机组协调控制策略的改进
摘要
以广州旺隆热电厂110MW热电联产机组为例
分析了热电联产机组电负荷与热负荷的耦合关系。在该机组协调控制策略中
增加了前馈回路
使机组既能很好地适应热负荷和电负荷的变化
达到在最大经济效益下的安全运行
并改善了机组重要参数的动态性能。
Abstract
Taking the 110 MW cogeneration units in Guangzhou Wanglong Thermal Power Plant as an example
the coupling relationship between electric load and thermal load of cogeneration units has been analysed.In the coordinated control strategy of said units
a feed forward circuit has been added
making the unit can perfectly suit to variation of thermal load and electric load
achieving safe operation under maximum economic benefit
and the dynamic performance of important parameters concerning said units has been improved.
