300 MW火电机组仿真机给水调节方案的改进

An Improvement on the Feedwater Regulation Scheme for a 300 MW Thermal Power Plant Simulation Unit

针对仿真机调试过程中有关给水自动调节系统原控制方案存在的设计缺陷进行分析 ,提出了改进方案 ,对仿真机有关设计模块和程序进行修改后 ,给水调节系统调节品质大大提高 ,实现了原来不能实现的保护功能。后又在生产实践中得到进一步证实。说明了仿真机不仅能进行岗位培训 。

In the course of the adjustment test of a simulation unit the design defects of the original control scheme of a feedwater automatic control system were analyzed and on this basis an improved scheme was proposed. After a modification of the related design modules and procedures of the simulation unit the regulation quality of the feedwater regulation system has been greatly enhanced. This brought about the realization of a formerly unachievable protection function, which has been verified and confirmed in production practice. It is noted that the simulation unit can be employed not only to conduct on-the-post training but also possesses a highly effective adjustment-test function.
