摘要: 以有源电力滤波器为代表的电能质量治理设备多用于补偿本地负载产生的谐波及不平衡电流。随着配网中非线性负荷的大量接入,本地补偿的配置策略存在成本高、效率低的问题,出现了面向网络电能质量全局综合提升的关键点治理设备配置需求。首先,提出了一种基于层次分析法和模糊隶属度的电能质量数据全局评价方法,作为衡量治理设备配置效果的尺度;其次,以全局配置效果、总装机数量和装机容量为优化目标,以网络各节点谐波含量及不平衡度均满足标准为约束条件,通过多目标粒子群算法确定治理设备最优配置节点及容量的配置策略;最后,通过搭建含有分布式不平衡及谐波负荷的IEEE-18节点仿真模型,验证所提全局评价及设备配置策略对于网络电压谐波及不平衡综合优化的有效性和优越性。

Abstract: Power quality control devices represented by active power filter are mostly used to compensate harmonic and unbalanced current generated by local loads. With the massive access of non-linear loads in the distribution network, the local compensation configuration strategy becomes expensive and inefficient. Therefore, the device configuration strategy for global improvement of network power quality is necessary. Firstly, a global evaluation strategy for power quality indices based on analytic hierarchy process is proposed to evaluate the configuration effects of control devices. Secondly, taking the global configuration effects, the total number and capacity of control devices as the optimization goals, and regarding the harmonic distortions and unbalance degrees of the nodes satisfying the standard as the constraint condition, the optimal configuration node and capacity of each device is determined by multi-objective particle swarm algorithm. Finally, an IEEE-18 node simulation model with non-ideal loads is built to verify the effectiveness and superiority of the proposed global evaluation and power quality control device configuration strategy for the comprehensive optimization of network harmonic and unbalance voltage.
