SVPWM Strategy Applying in Shunt Power Quality Controller

SPQC is a new kind of power electronic device, which can restrain harmonic dynamically, In order to verify the method applying in SPQC. the principle of SVPWM strategy is presented in detail and a novel SVPWM algorithm is proposed. Then a simplified method to calculate the operating time of each vector is offered and the way of judging sector is used,which avoids the nonlinear calculating .Moreover, the simulation models of SPQC are built up based on the strategy by power systems block of MATLAB/SIMULINK and the waveforms are given. The theoretical analysis and simulation results show that SVPWM control can decrease the total harmonic distortion. It indicates the validity and feasibility of the strategy applying in SPQC.
