大型抽水蓄能交流励磁机组发展的必要性及功能介绍

The Necessity of PSP Ac Excitation Unit Development and Function are Introduced

抽水蓄能电站具有调峰、填谷、事故备用功能等,而作为电力系统中的一个重要环节。由于交流励磁机组的种种优点而在国外被广泛的实用,并且新建的抽水蓄能电站中,交流励磁机组所占的比例越大越大,而国内抽水蓄能电站目前还全部是直流励磁机组。本文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进提供一些参考。

Pumped-storage power station has the function of peak shaving, filling valley, emergency, etc., as an important part of power system. Due to the Ac excitation unit widely practical abroad, and the new pumped storage power station, the greater the greater the proportion of Ac excitation unit, and domestic pumped storage power station are all is the Dc excitation unit. In this paper, based on the characteristics of Ac excitation unit and pumped storage and combined with actual application situation of abroad in pumped-storage power station adopts Ac excitation unit shall meet the functional finishing summed up, for domestic pumped storage power plant Ac excitation unit in advance to provide some reference.
