摘要
清洁能源对可持续发展战略的实现具有重要意义。针对清洁能源光伏发电并网分相电流控制存在的问题,研究提出了一种基于电力电子变压器的分相电流复合控制策略。采用分相电流调控方式,以变换器输出的负载电流,向单相牵引负载供电,减小电网中各节点间的不对称。仿真实验结果表明:通过研究提出的基于电力电子变压器的复合控制策略,在电网侧电压大小不一致的情况下,通过调节逆变器的输出,仍能获得期望的交流电压。研究的成果在清洁能源光伏发电领域具有广泛的应用前景和重要的实际意义。
Clean energy is of great significance for sustainable development strategies.For the problem of the gridconnected split-phase current control of the photovoltaic power generation of clean energy,this study proposes a hybrid control strategy of split-phase currents based on power electronic transformers.This paper adopts the splitphase current control method to supply power to the single-phase traction load by the load current output by the converter,so as to reduce the asymmetry among nodes in the grid.Simulation results show that the proposed com⁃posite control strategy based on power electronic transformers can still obtain the desired AC voltage by adjusting the output of inverters under the condition of inconsistent voltage on the grid side.The results of this study have broad application prospects and important practical significance in the field of the photovoltaic power generation of clean energy.
