摘　　要：变电站供电半径对中低压配电网的经济运行具有重要的影响,合理的变电站供电半径规划可以大大提高配电网的电能质量,并减少规划投资。文章以单位供电面积年投资费用最小为目标函数,建立变电站供电半径优化模型,研究变电站经济供电半径求解算法。建立基于线路电压损失约束的变电站供电半径模型,并对优化计算得到的经济供电半径进行电能质量校验。通过实际电网数据的测算,验证算法的准确性和合理性,计算结果可为地区配电网规划提供借鉴。Substation power supply radius has an important impact on the economic operation of medium and low voltage distribution network.Reasonable substation power supply radius planning can greatly improve the power quality of distribution network and reduce planning investment.In this paper,taking the minimum annual investment cost per unit power supply area as the objective function,the optimization model of substation power supply radius is established,and the algorithm for solving substation economic power supply radius is studied.The model of substation power supply radius based on line voltage loss constraint is established,and the economic power supply radius obtained by optimization calculation is verified by power quality.Through the calculation of the actual power grid data,the accuracy and rationality of the algorithm are verified,and the calculation results can provide reference for regional distribution network planning.
