摘　　要：电站循环水泵前池水位相对水源地水位下降,对汽轮机冷端系统安全性和经济性运行产生重要影响。通过定量分析和定性分析相结合,分析计算循环水泵前池水位下降对汽轮机冷端系统运行经济性的影响量,明确了对汽轮机冷端系统运行安全性影响的判定标准。形成了一套简便、实用的分析计算方法,对循环水取水系统存在的问题进行量化分析,同时为同类型循环水取水系统的设计选型工作提供了指导建议。Water lowering of the power station circulating water pump forebay compared to local water level influences the safety and economy of the steam turbine cold-end system. Through quantitative analysis and qualitative analysis ,the analysis of impact of water lowering of the circulating water pump forebay on the economic performance of the steam turbine cold-end system,clearly put forward decision criteria for operating safety of the steam turbine cold-end system. A set of simple and practical calculation method is developed, applied to the quantitative analysis on the problems existing in the circulating water system, at the same time provides guidance advice for the work of design and selection of circulating water system of same type.
