Research on Active Harmonic Compensation of Ship Photovoltaic Grid-connected Inverter
With the increasingly prominent problem of ship pollution and the increasingly strict greenhouse gas emission restrictions,a lot of research has been carried out in the shipping industry to combine solar energy with traditional energy to provide power for ships.However,the output of photovoltaic power generation has random and intermittent characteristics,and ship photovoltaic grid-connected inverters often cannot output at rated power,resulting in dynamic capacity surplus.On the other hand,with the increasing proportion of power electronic equipment and nonlinear loads in ship power grids,the problem of harmonic pollution in ship power systems becomes increasingly serious.To address the aforementioned issues,this article conducts in-depth research on integrating active harmonic compensation technology into marine photovoltaic grid-connected inverters,utilizing the remaining capacity of marine photovoltaic grid connected inverters to actively compensate for harmonics in the ship's power grid.
