Abstract

Abstract: Reactive power compensators based on three-phase voltage source converters continuously absorb and output adjustable reactive power. The mathematical model of the three-phase voltage source converter in a direct quadrature (DQ)-frame is analyzed. A decoupling method of the DC-side voltage and reactive power is designed through the state feedback linearization controlling strategy in non-linear differential geometry theory, and the PI controller parameters are set. Finally, the control method is verified effectiveness by Electromagnetic transient simulation software PSCAD/EMTDC. Simulation results show that the developed control method possesses better steady-state and dynamic behavior. The power factor of the compensation point is improved significantly.
