Active Harmonic Compensation

With the continuous improvement of photovoltaic power generation technology, people has higher requirement on the performance of the photovoltaic inverter. Currently, PV Inverter Grid process of the home and abroad, because the inverter put DC power into AC power frequency electric use the inverter principle and PWM control technology inevitably produce harmonics problems at the sine wave inverter formed. According to this kind of harmonic interference problem, the adaptive in-place active harmonic compensation technology were proposed, this effectively suppress the harmonic pollution to power network, solved the PV inverter output harmonic and reactive power problems, effective purification of power grid, filled the domestic and foreign photovoltaic inverter without output current harmonic compensation gap.

In this paper, a single-phase grid-connected photovoltaic (PV) inverter topology consisting of an H-bridge circuit, an inductive filter and a transformer interfacing the grid is considered. To improve the quality of the grid current and eliminate low order harmonics caused by the inverter’s dead time, a strategy of adaptive harmonic compensation method is proposed, and the parameters related are designed. The experiment results show that the proposed method has a good effect to mitigate low order harmonics and can improve the quality of current injected to the grid.
