一种带补偿计量的防强磁窃电方法

Anti-Strong Magnetic Stealing Method with Compensation Metering

针对强磁窃电,提出一种带补偿计量的防窃电方法。根据分析窃电补偿原理及计量方法,推导强磁窃电判断的依据,提出带补偿计量方法。根据电流互感器的误差可计算窃取电量,并进行追回。仿真结果表明:直流偏磁增大,电流畸变更加严重,计量误差增大,从而验证本防窃电方法检测有效性。

The compensation measurement method of anti-theft tape is proposed by strong magnetic interference.By analyzing the principle and measurement method of electric theft compensation,analyzing the judgment basis of magnetic theft,the measurement method with compensation is put forward.According to the error of the current Transformer,the stolen electricity can be calculated and recovered.The simulation results show that the detection effectiveness of this method is verified by the increase of DC partial magnetism,the more serious distortion of current and the increase of measurement error.
