摘要 介绍了采用数字补偿技术,改善高压电能计量装置功率源输出信号波形失真度指标的一种有效解决方案。该方案基于表源一体高压电能计量装置实施,利用现代数字合成及高速数字采样技术,以逐点补偿方式修正功率源输出波形,使高压电能计量装置输出的波形信号失真度指标大幅改善,从而抵消因为升压器、升流器以及高压电能表等非线性负载导致功率源输出回路正弦信号的失真,减少因功率提供的信号失真度大而导致高压电能表检定过程中引入的不确定度误差值。通过采用数字补偿技术使得高压电能计量装置在额定功率输出状态下信号波形失真度优于0.3%。 The use of digital compensation technology is introduced to improve the waveform distortion of power source of high - voltage electric energy metering device, which provides a solution to improve the distortion index. The scheme is earried out based on high - voltage electric energy metering device with the integration of the meter and its power source. Using modem digital synthesis and high - speed digital sampling technology, the power source output waveform is eorl'eeted by the point by point compensation method, so that the distortion index of waveform signal output of high - voltage electric energy metering device is greatly improved. The nonlinear load such as booster, large emTent generator and high - voltage electric energy meter leads to the distortion of sinusoidal signal in the output circuit of power source, which reduces the uncertainty error of high - voltage electric energy- meter by reducing the distortion of the signal provided by the power. By using the digital compensation technology, the distortion of high - voltage electric energy metering device in the rated power output state is better than 0.3 %.
