分析某电厂二期1000MW机组给水泵汽轮机的控制策略和控制逻辑优化情况,介绍小机超速保护、METS电源失电保护等硬回路的设计、实施及调试中遇到问题的解决办法,通过对给水泵汽轮机的控制逻辑及电气回路的分析,阐述给水泵汽轮机的控制优化情况。%This essay analyzes the control strategies and control logic optimization of the feed-pump turbine of the IO00MW unit in the second-stage construction of a power plant. Besides,it introduces the over-speed protection of the turbine as well as the designs and the solutions to the problems in the implementation and debugging of the hard circuits such as the power-loss protection of the METS power source. Based on the analyses of the control logic and electrical circuit of the feed-pump turbine, this essay also expounds its control optimization.
