摘要
提出了一种新型的由超级电容器储能模块、光伏阵列、升降压DC/DC变换器、双向DC/DC变换器、并联逆变器和能量管理系统组成的微网统一电能质量调节器,分析了主电路的基本结构,提出了调节器在并网状态下针对不同电能质量问题控制指令的生成,以及超级电容器和逆变器的连接模块、光伏电池对超级电容器充电模块的设计。仿真结果表明,所提出的统一电能质量调节器可以充分利用光伏电池发出的多余能量,通过超级电容器的快速响应能力,对微网中的多种电能质量问题进行有效治理。
A UPQC （United supercapacitor, photovohaie Power Quality Conditioner） is modules,Boost-Buck DC/DC proposed for microgird ,which is composed of converter,bidirectional DC/DC converter, shunt inverter and energy management system. Its structure is analyzed and it is proposed to generate the control instruction according to different power quality problems for grid-connected UPQC. The connecting module between supercapacitor and shunt inverter and the power charging module of supercapaciter are designed. The simulative results verify that,the proposed UPQC takes full advantage of the redundant power of photovohaic ceils and the rapid response capability of supercapacitors to solve various power quality problems of microgrid.
