某型燃煤链条锅炉给水控制仿真建模

The simulation modeling about feed water control of a sort of coal chain boiler

综述了链条炉汽包水位三冲量串级控制系统的控制策略及仿真控制系统的建模特点,分析了仿真控制系统与实际控制系统整定参数存在不一致的原因,及系统存在积分饱和现象产生的原因和解决方法。运行情况表明,仿真控制系统有较高逼真度且有良好的控制品质。

This paper summarized the control strategy of drum water level three-element value cascade control systems, and the model ing characteristics of simulation control system. The reason for the inconformity between simulation control systems with practical con- trol system setting parameter was analyzed. Meanwhile, the reason and solution of integral saturation phenomenon in systems were pro- vided. Operation showed that the simulation control system had a high fidelity and good control quality.
