摘　　要：论述了统一电能质量调节器的基本拓扑结构和串、并联变流器的工作原理,提出基于广义瞬时无功功率理论的检测方法和控制策略,为矿区生产提供绿色电源的低压电网电能质量补偿技术。仿真结果验证了统一电能质量调节器对改善矿区低压电网电能质量的可行性与有效性。The paper discusses the basic topological structure of the unified power quality conditioner （ UPQC ） and the operation principles of series and shunt converter. Detection methods and control strategies based on the extended instantaneous reactive power theory are proposed, which provided a power quality compensation technology of low voltage power network with green power supply for mine production. The simulation results verify the feasibility and effectiveness of UPQC in improving power quality of mine low voltage power network.
