300 MW机组给水泵自动并泵功能设计分析

Design Analysis of Automatically Combining Function of 300 MW Unit's Feed-water Pump

大机组给水泵手动并泵操作复杂 ,易造成汽包水位大幅波动。实现自动并泵功能对减轻运行人员劳动强度 ,提高机组的自动化水平及可靠性 ,具有切实的意义。本文从分析给水泵并泵操作过程中的一般性热力特点出发 ,根据其功能实现要素 ,提出自动并泵控制功能设计的初步方案。

Procedure of manually combing large size unit's Feed water Pump is complex and easy to cause much change of drum level.realization of auto combination can release operator and improve unit's Auto level and reliability.Analyzing the general thermal features in process of combining Feed water Pump,according to the conditions of its function,auto combination control function's primary scheme is presented in this article.
