分析了微网高渗透率对配电网电能质量的作用机理,包括对配电网电压及电流质量的作用机理。通过分析对比原有电能质量调节器与微网并网逆变单元的相似性,完成了微网高渗透率下配电网电能质量调节器的定制,并对其系统结构与控制原理进行了详细的分析。采用一种改进型的复合指令电流合成算法,实现了微网高渗透率下配电网电能质量调节器的复合控制。仿真与试验结果验证了该方案的可行性和有效性。
A detailed analysis of the mechanism for the high permeability of micro grid was given in the distribution network ,including the voltage quality and current quality. By the analysis and comparison of the similarity between the original power quality conditioner and the grid-connected inverter unit, this paper customized the power quality conditioner for distribution network with the high permeability of micro grid, and analyzed the structure and control principle of the system. Using an improved synthesis algorithm of compound instruction current, it realized the compound control of the power quality conditioner. A theoretical analysis with complete simulation and experiment of the system was presented to prove the exeellent performance of the proposed technique.
