Research on flexible excitation system applied to improve transient stability characteristics of the receiving-end power grid

Zhejiang dianli, 2022
The transient forced excitation of the traditional excitation system used for synchronous condenser is limited and unmaintainable. A flexible excitation system can improve the crest value of transient forced excitation and maintain the forced excitation ...
