| 摘 要： | 通过分析统一电能质量调节器(Unified Power Quality Conditioner,简称UPQC)的工作原理,以最常用的左串-右并主电路结构为例,建立其基波稳态等效电路,对其能量流动关系进行分析.在此基础上,结合最小能量法论证推导串、并联侧功率需求公式,确定主电路的容量选取原则.最后通过实验验证主电路容量选取原则的合理性.

| Abstract: | Through analyzing the principle of unified power quality conditioner(UPQC),fundamental steady-state equivalent circuit taking the left series-right parallel structure as example is built.The relationship of energy flow is analyzed.The power demand formulas of series side and parallel side are demonstrated and derived on this basis of minimum energy method. The selected principle of main circuit capacity is determined.Finally,experimental results verify the rationality of the selected principle. |
