摘要:
针对配电网中存在单相负载或冲击性负载导致系统三相电压不平衡现象严重的问题,提出了一种基于新型级联多电平稳压控制技术,介绍了其主电路拓扑结构、等效数学模型,并设计了分段控制器。PSCAD 仿真结果表明,所设计的控制器结合了模糊控制自适应、鲁棒性强及PI 控制稳态精度高等优点,稳压控制性能好;新型级联型多电平稳压控制技术可实现电网与负载的有效隔离,提高了系统稳定性及带载能力。
Abstract:
Due to the three-phase voltage unbalance caused by single-phase load and impact load existed in distribution network, it proposed a novel cascaded multilevel regulated voltage control. Its main circuit topology and equivalent mathematical model were introduced, and the composite segmented controller was designed. PSCAD simulation results show that the controller combines the merit of good adaptive and robustness of fuzzy control, and high accuracy of PI control in steady state, which has good regulated voltage control performance. With this novel cascaded multilevel regulated voltage control method, it can achieve an effective separation between grid and load, by which the system stability and load capacity are improved.
