提出了一种新的配电系统供电能力数学模型。首先，基于N一1安全准则给出了包括配电系统最大供电能力、变电站供电能力、网络转移能力和可用供电能力等供电能力相关指标的定义。其次，建立了最大供电能力模型，该模型分为最大供电能力子模型和负载均衡子模型，将其转化为线性规划问题后，逐次求解得到最大供电能力并达到主变压器负栽均衡分配。最后，通过算例验证了模型的有效性，提高了解析计算最大供电能力方法的精度。

A new supply capability model for distribution systems is proposed. Firstly, based on N- 1 safety criterion, definitions are given to the related indices including the distribution system maximum supply capability, substation supply capability, network transfer capability, available supply capability, etc. Then the maximum supply capability model is developed and divided into two parts, the maximum supply capability sub-model and the load balance sub-model. After the problem is transformed into one of linear programming, the maximum supply capability is obtained by step by step solution and the balanced distribution of the main transformer loads is attained. Finally, a case study is given to verify the effectiveness of the proposed model and improves the analytic calculation accuracy of the maximum supply capability.
