With the vigorous development of new energy sources, wind power generation technology has been developed rapidly. Due to the reverse distribution of wind energy resources and load centers, large-scale wind power transmission is inevitable. Using series capacitor compensation technology is an effective measure to complete large-scale wind power transmission, but may induce sub-synchronous oscillation...
