Abstract :
According to the traditional p-q theory had many problems, the improved p-q method is studied in this paper. The distorted voltage is transformed to ideal voltage through the space vector. Harmonic suppression and reactive power compensation are finished under the distorted voltage by use of three-phase four-wire four-leg active filter. Comparing to the traditional p-q theory, the simulation results show this method is effective.
