In this paper,the leakage current is predicted by establishing the historical database of leakage current and the prediction model based on the similarity of historical data.The leakage current is predicted by analyzing the correlation of eigenvalues affecting the leakage current,selecting similar data in the historical database,and calculating the fitness between similar data and prediction data.The simulation results show that the prediction model based on the historical database can accurately calculate the leakage current of street lamp lines under different working conditions,with less error from the actual leakage current and strong applicability.
