Automatic monitoring method for simultaneous line loss in intelligent distribution networks under heavy rainfall and flooding
The current conventional distribution network line loss monitoring methods mainly achieve the prediction of line loss rate by extracting line loss parameters,which leads to poor line loss monitoring due to the lack of control of line loss errors.In this re-gard,an automatic monitoring method for line loss of intelligent distribution networks under heavy rainfall and flooding disasters is pro-posed for the same period.The transmission line topology is analysed to clarify the causes of abnormal line losses,and the line loss data is dimensionally reduced and standardised.On this basis,a line loss sample characterisation system is constructed and the error between the theoretical and actual line losses is used to judge abnormal line losses.In the experiment,the proposed method is tested for accuracy.The experimental results show that the proposed method has a small relative error value when monitoring the line loss o-ver the same period,and has a more satisfactory monitoring effect.
