摘要
分析当前1 000 MW超超临界发电机组除氧器水位调节系统不完善的两个主要原因,一是调节器参数整定没有做到科学化,二是可以避免的状态切换扰动没有针对性的逻辑设计。提出优化方法,一是给出除氧器水位自动调节器参数整定计算方法,二是无扰切换判断逻辑设计。
This paper analyzes two main causes of the imperfection of the water level regulating system of the deaerator of the current 1000 MW ultra-supercritical generating unit. One is that the parameter setting of the regulator is not scientific,the other is that there is no targeted logic design for the state switching disturbance which can be avoided. Two optimization methods are introduced as well. One is the method of calculation for the parameter setting of the automatic water level regulator of the deaerator while the other is the design of undisturbed switching logical judgment.
