摘要
通过对岭澳一期给水泵配置方案的最终确定过程及其实际运行情况回顾,在对目前国内外核电站给水泵配置进行研究的基础上,对几种典型的配置进行了技术经济比较和分析。在综合考虑经济性和可靠性后认为:2×50%汽泵+2×25%电泵方案优于2×75%汽泵+1×50%电泵方案。如果电动给水泵电机的容量可以从原来的10MW提高到14～15MW,电压等级从原来的6.6kV提高到11kV,单台电动给水泵的容量就可达75%,则3台电泵的方案也可以考虑采纳。
After reviewing the selection of the feed water pump configuration for Ling＇ao I Nuclear Power Station and its operation, and based on the study results for several feedwater pump configurations which have been used in domestic and foreign nuclear power stations, several typical feed water pump configurations are compared and analyzed technically and economically. Considering the economics and reliability, we think the configuration of 2 × 50% turbine driven feedwater pump plus 2 × 25% electrical driven feedwater pump is better than that of 2 × 75% turbine driven feedwater pump plus 2 × 50% electrical driven feedwater pump. If the capability of one motor of feedwater pump can be increased from 10MW to 14 - 15MW and the voltage can be increased from 6.6kV to 11kV, the capacity of one electrical driven feedwater pump can reach 75% of the total capacity, then the configuration of 3 × 50% electrical driven feedwater pump is also accepted.
