摘　　要：在电力系统发展过程中,窃电行为不仅会产生巨大的经济损失,还会引起火灾,影响电力公司的安全运行。为此,设计了基于无迹卡尔曼滤波的反窃电自动化检验系统。构建检验系统模型,根据模糊逻辑函数,计算卡方验证匹配参数。利用离散算法建立检验设备的系统状态方程和系统测量方程,加权处理信息噪音干扰。分析无迹卡尔曼滤波动状态,计算均方误差值,实现反窃电自动化检验。实验结果表明,基于无迹卡尔曼滤波的反窃电自动化检验系统准确率在98%以上,可保证电力公司的安全运行。In the process of power system development,electricity theft will not only cause huge economic losses,but also cause fire,affecting the safe operation of power companies.For this reason,an automatic anti stealing inspection system based on unscented Kalman filter is designed.The test system model is constructed,and the chi square verification matching parameters are calculated according to the fuzzy logic function.The discrete algorithm is used to establish the system state equation and system measurement equation of the inspection equipment,and the information noise interference is weighted.Analyze the fluctuation state of the unscented Kalman filter,calculate the mean square error value,and realize the automatic inspection of anti stealing electricity.The experimental results show that the accuracy of the anti stealing automatic inspection system based on the unscented Kalman filter is more than 98%,it can ensure the safe operation of the power company.
