摘　　要：常规的转供负荷能力评估分析方法以负荷恢复率为主,评估结果与实际工况不符。因此,需要设计配电线路的转供负荷能力评估分析方法,建立配电线路转供负荷能力评估指标,将转供后节点电压是否越限与线路传输容量是否过载作为评估指标,评估转供负荷能力。确定配电线路转供负荷的随机潮流,将负荷随机性与波动性考虑在内,预测负荷随机变化,从而确保负荷能力评估的准确性。基于此,本文采用算例分析,验证了该方法的评估效果更佳,能够应用于实际生活中。The conventional evaluation and analysis method of transfer load capacity is mainly based on load recovery rate,and the evaluation results are inconsistent with the actual working conditions.Therefore,it is necessary to design the evaluation and analysis method of transfer load capacity of the distribution line,establish the evaluation index of transfer load capacity of the distribution line,and take whether the node voltage exceeds the limit after transfer load and whether the transmission capacity of the line is overloaded as the evaluation indexes to evaluate the transfer load capacity.The random power flow of the distribution line transfer load is determined,the load randomness and fluctuation are considered,and the random change of load is predicted,so as to ensure the accuracy of load capacity assessment.Based on this condition,this paper uses a calculation analysis to verify that the this method has better evaluation effect and can be applied to real life.
