摘要
Abstract
SHEPWM has the advantage of eliminating the selective harmonics by optimizing switching time sequence. In this paper, an accurate method is used to calculate the initiate value of switching angles. At first, switching angle values of the phase a are obtained by use of MATLAB function ' fsolve'. Then, switching angle values of the phase b and c can be got according to the characteristic of three-phase symmetry. At last, the SHEPWM simulation model based on MATLAB/SIMULINK is established and applied to the direct voltage control D-STATCOM system. Simulation results show that the system can not only stabilize the voltage at the PCC (point of common coupling) bus but also effectively eliminate the selective low harmonics of the inverter’s output voltage.关键词
