Abstract

In order to verify the compensation effect of high voltage static var generator. The system structure of cascaded H-bridge is adopted. The bipolar CPS-SPWM and monopole frequency doubling CPS-SPWM modulation modes are compared by simulation. The instantaneous reactive power detection principle is derived theoretically. The reactive power can be compensated quickly by using monopole frequency doubling CPS-SPWM modulation mode and instantaneous reactive power detection. Using Matlab/Simulink to build 10kv High-voltage SVG, the fast and accurate reactive power compensation is realized under the switching of inductive reactive power and capacitive reactive power. The reliability of the design is verified by simulation.
