摘要
随着船舶污染问题的日益凸显与温室气体排放限制的日趋严格,将太阳能与传统能源相结合为船舶提供动力,在航运业已经开展了大量研究.然而光伏发电出力具有随机性和间歇性特点,船舶光伏并网逆变器往往无法以额定功率输出,存在动态容量剩余.另一方面,随着船舶电网中电力电子设备及非线性负载的比重逐渐增加,船舶电力系统谐波污染问题愈发严重.为解决上述问题,本文围绕将主动谐波补偿技术融入到船用光伏并网逆变器中展开深入研究,利用船舶光伏并网逆变器的剩余容量对船舶电网谐波进行主动补偿.
Abstract
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.
