In this paper

the application of proportional resonance control strategy on compensation voltage control is studied deeply with distributed synchronous series compensator as study object and the feedback control of compensation voltage as the study subject. In view of the features of distributed synchronous series compensator

the time domain analytical expression the tracking error of compensation voltage is takenas the base to explore the design method of parameters of the compensation voltage controller. It is shownby the experimental result that use of proportional resonance control strategy can assure safe and stable op-eration of the distributed synchronous series compensator and obtain high precision compensation voltage.
