Air supply automatic control optimization of 330 MW Units
摘要
针对某330 MW机组送风自动控制系统调节效果不理想、投运率偏低的问题
设计新的氧量均值计算方法和超前调节的送风自动控制策略。实际运行结果表明
新设计的送风自动调节系统能满足机组稳态及变负荷工况运行要求
有利于提高送风自动调节效果和投运率。
Abstract
For the problem of poor adjusting effect and low using rate of air supply automatic control system in a 330 MW unit
the new oxygen mean calculation method and advanced adjustment of air supply automatic control strategy have been designed.Actual operation results show that the new design of air supply automatic control system can satisfy the steady and variable load operation requirements. It can improve the air supply automatic control regulation effect.
