Abstract: According to the requirements of quickly and reasonably formulating load transfer measures after

distribution network failure at this stage，a reliability evaluation scheme for fault transfer based on K-fold verification was introduced. Square up various power supply modes，according to the energy balance equation，the load transfer effect evaluation index was established. Taking the minimum power loss as primise，considering the multiple factors such as operating status，characteristics and the external environment，the equality and inequality constraint conditions of the distribution network fault transfer evaluation model were constructed. The K-fold verification data processing method was adopted to fully pre train the historical data and complete the fitting of key constraint parameters of distribution network transfer，which is convenient to compare with the subsequent possible fault information，and can minimize the preparation time of transfer plan. The dispatcher can draw up reliable transfer measures according to the comparison results and select the transfer path accordingly. It has certain reference value for the arrangement of the actual operation mode and the adjustment.
