抽水蓄能电站首机首次水泵启动工况试验研究

Experimental research on first unit's initial startup under pump condition of pumped-storage power station

迄今为止,国外一些大型抽水蓄能电站首机首次启动试验大多采用的是水轮机工况启动模式。这种工况模式往往会导致工程建设工期长及建设成本高,对工程建设方而言是一个很大的负担。为此,结合宝泉抽水蓄能电站的实际情况,对于将水泵工况作为该电站的首机首次启动模式展开了分析研究和启动试验。结果表明,对于电站上库没有天然来水或者是径流不足的大型抽水蓄能电站,将该启动方式作为一种正常的首机首次启动模式,非常有利于节约充水成本,缩短建设工期,使工程提前投产发电并发挥经济效益。因此,无论是从技术上还是从经济上来分析,水泵启动模式都应该是一种优选模式。

The operating condition of turbines has been nostly applied in first unit＆#39;s initial startup in foreign large - scale punped - storage power station so far. However,this node often leads to long construction period and high cost,laying a great burden for the project owner. Thus,in view of the actual situation of Baoquan Punped - Storage Power Station,the research and startup experinent are conducted for first unit＆#39;s initial startup node under punp condition. The results show that this startup node can be connonly used for the station without water in upper reservoir or lack of runoff,which is conducive to saving water filling cost and shortening construction period,so as to nake the project put into operation and generate econonic benefits ahead of tine. Therefore,the startup node under the operating condition of punp is preferable.
