泗阳二站反向发电运行方式选择的研究

THE RESEARCH OF INVERTED POWER GENERATIONOPERTION WAY SELECTION FOR SIYANG SECONDPUMPING STATION

关于“泵机组反向发电运行”，还没有见到专门的研究，本文从水力资源入手，通过各种运行方式的比较和经济分析，论证了泗阳第二抽水站反向发电采用电机不变极运行方式的合理性，并且阐述了“电机变极运行时发电效率比不变极运行时高得多，并不等于其发电量大得多”这一容易引起混淆的观点。

The research about″pumpsets operating in inverted power generation″ has not be seen today.With the analysis of water resources, the comparison among the all kinds of operation ways and economic ben-efit,the rationality of SIYANG PUMPING STASTION Ⅱusing the sarne poles operational way when itruns in inverted power generation is demonstrated in this paper. The opinion of ″ the generation efficiency ismore higher when synchronous motor operates with the changed poles than with the same poles, but it's notequal to that it's totall generation aniount is more greater than the same poles operation way″ is also expound-ed in the paper.
