摘要：Previous harmonic suppression system is generally through the system detection for harmonic content in the system and corresponding harmonic frequency is obtained by active filter unit but in the opposite direction of harmonic signal to offset the harmonic wave of output voltage and current. This paper embarks from the internal system, according to the superposition theorem in the basic of the original, on the basis of improved droop control of a harmonic domain droop control strategy, finally through every harmonic controller output signal and fundamental domain prolaose controller output signal superposition for inverter input signal. This method from harmonic source in order tu reduce the system harmonic content, effectively reduce the use of filter equipment, improve the effiviency of the system, and increase the response speed of the system, to a certain extent, to reduce the harmonic THD has certain significance.
