中文摘要:
      抽水蓄能电站具有调峰、填谷、事故备用等功能,作为电力系统的重要环节。由于无级调速机组的种种优点而在国外被广泛的应用,在新建抽水蓄能电站中,无级调速机组应用的比例越来越大。其主要形式是交流励磁机组,而国内抽水蓄能电站目前还全部是直流励磁机组。根据交流励磁和抽水蓄能的特点并结合国外实际应用情况对在抽水蓄能电站中采用交流励磁机组应当具备的功能进行整理归纳,为国内抽水蓄能电站中交流励磁机组的推广提供一些参考。
英文摘要:
      Pumped-storage power stations with such functions as peak shaving, valley filling and emergency standby, serve as an important link in the electric power system and are extensively applied overseas because of many advantages of stepless variable-speed units, which makes up an increasing proportion among the newly built pumped-storage power stations. They are mostly AC excitation units, while all of domestic pumped storage power stations are using DC excitation units. Based on the characteristics of AC excitation and pumped storage and considering actual application situation in other countries, this paper summarizes the functions which the AC excitation units used at AC power stations should have, thus providing some references for the promotion of AC excitation units at pumped-storage power stations.
