This article introduced the steady-state and transient voltage control strategy of ±200 Mvar STATCOM in China Southern Power Grid from the perspective of the actual operation of STATCOM. Then set a typical single-phase ground fault as an example, analysis the transient waves during the startup and reactive power output characteristics detailed with the help of substation recorded waves in 500kV BEIJIAO substation. The results proved that STATCOM can give a reliable and rapid response in grid fault, reflecting a good reactive support capability.
