摘要
某滨海核电站循环水系统采用直流冷却方式,由于其取排水隧洞较长,投资较大,影响了循环水系统方案的选择,结合厂址的实际条件通过冷端优化对1机2泵定速、1机2泵变频、1机3泵定速三种方案进行了分析,考虑到电厂投运后需要调峰运行,综合技术比较,推荐1机2泵变频方案。
Direct current cooling method is adopted in the circulating water system of a coastal nuclear power plant,Due to its long intake and drainage tunnel and large investment,it affects the choice of circulating water system options,This paper analyzes the three schemes of 1 unit with 2 fixed speed pumps,1 unit with 2 variable frequency pumps,1 unit with 3 fixed speed pumps through cold end optimization combined with the actual conditions of the plant site,considering the need for peak shaving operation after the power plant is put into operation,comprehensive technology For comparison,a frequency conversion scheme of 1 unit with2 pumps is recommended.
