摘要
针对不同补偿策略下统一电能质量控制器的功率变化问题,从UPQC与整个电力系统的功率交换的角度出发,建立了UPQC不同补偿策略下的统一功率模型,分析了不同补偿策略下UPQC串、并联补偿部分以及各补偿部分与整个电力系统的有功功率和无功功率的交换关系;提出采用最小视在功率补偿方式有效降低串联部分、并联部分和整个UPQC的视在功率,减小系统损耗并提高系统运行的安全性,仿真验证了最小化补偿策略的有效性。
Aimed at the problem of power variety of unified power quality conditioner under different compensation strategies, from the angle of power transform of UPQC （unified power quality conditioner） and the whole electrical system, the unified power model is established under different compensation strategies. The commuted relations of active power and apparent power between UPQC and the whole electrical system are analyzed. The minimum apparent i^ower compensation method is put forward to reduce the apparent powers of series part and shunt part and the whole UPQC, and decrease the losses of the system and improve its safety. The emulated results verify that the proposed method is right and feasible.
