摘　　要：该文采用建立泄漏电流历史数据库与基于历史数据相似性的预测模型方法来对泄漏电流进行预测。通过分析影响泄漏电流的特征值相关性,选取历史数据库中的相似数据,计算相似数据与预测数据的适配度来进行泄漏电流值预测。仿真结果显示,依托历史数据库构建的预测模型能够准确计算出不同工况下路灯线路的泄漏电流值,与实际泄漏电流误差较小,适用性强。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.
