提出了一种基于参考阻抗的多不平衡源责任分摊方法。建立了多不平衡源责任分摊的数学模型，定义了4个量化指标，给出了多不平衡源责任分摊的步骤，并且通过某三用户系统仿真模型和某钢铁厂10 kV供配电系统测试数据证明了该方法的有效性和合理性。最后，参考阻抗变化对量化指标的敏感性表明，该定量评估方法误差较小，提高了多不平衡源责任分摊的精确性。

A method of responsibility proration among multiple three-phase unbalanced sources based on the reference impedance method is proposed.A mathematical model of responsibility proration among multiple three-phase unbalanced sources is developed,four quantitative indices are defined,and the detailed implementation steps are given.The validity and rationality of the method are proved by a simulation system model with three users and the measured data of a 10 kV power system in a steel plant.Finally,the sensitivity analysis between reference impedance and quantitative indices shows that the error of the method is small owing to the improved accuracy of the responsibility proration among multiple three-phase unbalanced sources. <br> This work is supported by Major Science and Technology Projects of Qinghai Province(No.2012-J-A1).
