摘 要:小水電集中上網(wǎng)地區(qū)電壓問題嚴重,水電機組進相運行可以為電網(wǎng)提供一定的無功支撐。研究了小水電進相運行對電網(wǎng)的降壓效果,分析了進相運行對電網(wǎng)網(wǎng)損的影響,提出通過適當安排小水電進相運行,參與地區(qū)電網(wǎng)無功電壓調(diào)節(jié)等方法,來提高小水電集中并網(wǎng)地區(qū)電壓管理水平,改善電能質(zhì)量。
關鍵詞:進相;小水電;無功電壓;電網(wǎng)損耗

Abstract: The voltage problems of concentrated grid connected areas of small hydropower are serious. The leading phase operation of hydroelectric generating set could provide certain reactive power support for the power grid. This paper researched on the reduction voltage effect of the power grid from the small hydropower leading phase operation, analyzed the impacts of leading phase operation on the grid loss and proposed to properly arrange the small hydropower leading phase operation with participation in the reactive voltage regulation of regional power grid, to improve the voltage management level of concentrated grid connected areas of small hydropower, together with the power quality.
Key words: leading phase; small hydropower; reactive voltage; grid loss
