| 摘 要： | 针对10 kV配电网外挂能力的评估，提出了一种针对该配电网外接最大负荷的计算方法，利用配电网各个负荷节点功率、电压数据求出网络全部节点电压、电流，并以负荷功率约束为条件求出外挂负载时配电网络分支电流的改变量，计算了外挂负载后各支路功率损耗，根据主变供电容量求出外挂负荷的最大能力。实例计算结果表明，该方法行之有效。

| Abstract: | As for assessment of 10 kV power distribution network plug in capability, this paper proposes a calculation method of distribution network for the maximum external load. Firstly, load nodes' power of distribution network and voltage data are used to obtain all nodes' voltage and current in the network. And then taking load power as constraints, changes of different branch's current of distribution network with plug load are calculated and the power losses of each branch are obtained. Finally, the maximum capacity of plug load is calculated according to the main transformer power supply. The results of example show that the method is feasible and effective. |
