Selection and analysis of current limiting reactors for generator branch circuits of pumped storage power station

Abstract

Starting from theoretical basis and engineering practice, this article derives a calculation formula for the reactance percentage of current limiting reactors that is in line with engineering practice, intuitive and easy to understand, and convenient to use. Taking the Qingyuan Pumped Storage Power Station as an example, the main process of selecting current limiting reactors was analyzed, and the main technical indicators of current limiting reactors were calculated. The selected parameters such as voltage drop and maximum temperature were verified to ensure that they meet the requirements of the specifications and practical engineering needs.
