摘　　要：由于中压配电网存在结构复杂、测量系统不全等问题,工作人员很难进行有效的减损工作。因此,文章提出一种基于广度优先的前推回代精准线损计算方法。该方法根据实际的馈线数据,将馈线拓扑进行分层,以层为单位利用前推回代法计算馈线损耗。通过实例分析得到:文章提出的计算方法具有精确的计算结果,通过指导完成对线路改造,合理利用资源,有效解决线损率偏高的问题,具有良好的应用价值。Due to the complex structure and incomplete measurement system of medium voltage distribution networks,it is difficult to carry out effective loss reduction work.Therefore,an accurate line loss calculation method of first push back substitution based on breadth optimization is proposed.This method divides the feeder topology into layers based on actual feeder data,and calculates feeder losses using the forward backward substitution method on a layer by layer basis.Through case analysis,it is found that the calculation method proposed in the article provides accurate results.By guiding the completion of line renovation,rational utilization of resources,and effectively solving the problem of high line loss rate,the proposed method has good application value.
