摘　　要：通过测量电抗器的端电压和端电流,参考CPU提供的标准正弦和余弦函数,从而提取电压与电流的有功和无功分量.根据基波电压和电流的相位关系,推导出电抗器损耗计算公式.由于损耗计算值每个周期波动较大,将每周期计算结果利用巴特沃斯滤波器去抖后,实测结果表明,相角误差小于0.72度,损耗波动值小于0.2%,说明该方法切实可行,测量结果准确可靠.According to the standard sine and cosine functions provided by the CPU,it is necessary to calculate the active and reactive components of the fundamental voltage and current by measuring the reactor terminal voltage and current. According to the phase relationship between the fundamental voltage and current,reactor loss formula can be deduced. Due to the loss calculation value for each cycle fluctuations,it is necessary to limit the calculating result waved of the reactor loss by using the digital Butterworth filter. Test results show that the error of the phase angle is less than 0. 72 degree,the error of the fundamental loss is less than 0. 2%,indicating that the method is feasible and the measurement results are accurate and reliable.
