According to the project experience of the first relocatable static VAR compensator（RSVC） in China applied in Jiangxi power grid， some methods of project design are put forward. A new 220 kV voltage control strategy with 10 kV voltage limit is presented here to meet the requirement of transformer substation voltage control. For realizing the relocatable system， the distributed monitoring system and compact valve body design are applied. By the analysis of experimental and operational data， some beneficial principles and attentions are drawn when RSVC is applied. The conclusions will be good for the implementation of SVC in China power grid.
