The feedwater pump improvement project of steam turbine group 200mw in power plant has been implemented in 1998 摘要某发电厂于1998年实施了200mw汽轮机组的给水泵改造工程，将电动给水泵改为小汽轮机拖动的汽动给水泵。
In china , feedwater control system of most power plants can not be in automation at full range , especial during low load after synchronization 在国内,有相当一部分机组给水控制系统不能投入全程自动,尤其在并网后低负荷阶段。
The paper points out an intelligent full range feedwater control system , based on analyzing dynamic characters of feedwater system and fuzzy logic theory 本文通过分析给水系统的特点和被控对象的动态特性,总结国内机组投产以来出现的问题,制定出了切实可行的全程控制方案。
As per the contract , feedwater control system shall be in automatic mode at full range , and the requirement of drum level control index of feedwater control system is high 按照合同技术要求,一是给水控制系统必须全程投入自动;二是对给水控制指标(汽包水位)提出了较高的要求。
With the development of process control technology the requirements of automatic control level for generating unit are increasing rapidly . full range feedwater control system is one example 随着控制技术的不断发展,对发电机组自动化水平的要求也越来越高,全程给水自动控制系统就是其中之一。
