摘　　要：针对0.4 kV配电网负荷波动性,采用分时段无功补偿优化模型改善配电网运行质量。基于配电网日负荷曲线构建了无功补偿优化分段模型,然后根据配电网网损灵敏度和电压偏移指标建立了无功补偿点筛选方法,并通过分析多优化目标对所有模型进行求解,在配电网负荷分段和负荷曲线分段点下确定最优无功补偿优化方案。以IEEE 33节点为例对构建的无功补偿优化模型进行仿真分析,验证了所构建模型的有效性。Aiming at the load fluctuation of 0.4 kV distribution network,the time-based reactive power compensation optimization model is used to improve the operation quality of distribution network.Based on the daily load curve of distribution network,an optimized segmentation model of reactive power compensation was constructed.Then,according to the network loss sensitivity and voltage offset indexes of distribution network,a reactive power compensation point screening method was established.By analyzing multiple optimization objectives,all models were solved.The optimal reactive power compensation optimization scheme was determined under the load segment and load curve segmentation point of the distribution network.Taking IEEE 33 node as an example,the constructed reactive power compensation optimization model was simulated and analyzed,and the effectiveness of the constructed model was verified.
