It can serve for synchronous spinning reserve , load following , frequency control and synchronous condenser operation . due to the difficulty of quantitative calculation , the typical cases on dynamic function of pumped storage plant are qualitatively analyzed in this paper 抽水蓄能電站具有運(yùn)行靈活、啟動(dòng)迅速的特點(diǎn),其在電力系統(tǒng)的動(dòng)”態(tài)效益主要表現(xiàn)在緊急事故備用、負(fù)荷跟蹤、調(diào)頻和同步調(diào)相上。
Static benefits are generated from peaking and valley - filling , which are further divided into capacity benefits and coal saving benefits . dynamic benefits come from its fast starting and flexible operation , including frequency regulation , synchronous condenser operation , fast coverage of steep load gradient and synchronous spinning reserve . as for the calculation of static benefits of pumped storage plant , the alternative coefficient method is normally adopted at present 目前在抽水蓄能電站的靜態(tài)效益計(jì)算中,一般采用替代系數(shù)法,即用抽水蓄能電站的裝機(jī)容量乘以容量替代系數(shù)( 1 . 05 1 . 1 )計(jì)算抽水蓄能電站的替代容量;用抽水蓄能電站的發(fā)電量乘以電量替代系數(shù)( 1 . 05 )計(jì)算替代電站的發(fā)電量,再根據(jù)循環(huán)效率的大小計(jì)算抽水蓄能電站的燃料消耗。
