摘要:
漏电流的准确计算对于保证人身和设备安全是非常重要的。由于非线性电力电子器件的广泛应用,配电线路的漏电流为交直流混合复杂信号,目前的计算方法难以精确计算。为此,提出了一种结合全相位傅里叶变换的方均根值算法。以漏电流仿真值作为基准值,根据采样数据的方均根值、基准值以及全相位傅里叶变换的计算值来计算配电线路的漏电流,高效准确。算例证明了算法的准确性与有效性,为配电网漏电流的准确计算提供了一种新方法。
Abstract:
Accurate calculation of leakage current is very important to ensure personal and equipment safety. Due to the wide application of nonlinear power electronic devices, the leakage current of distribution lines is a complex mixed AC/DC signal, so the current calculation method is difficult to calculate accurately. Therefore, a square mean root-value algorithm combining all phase Fourier transform is proposed. Taking the leakage current simulation value as the reference value, the leakage current of distribution line is calculated according to the square mean value, reference value of sampling data and the calculated value of all phase Fourier transform, which is efficient and accurate. The calculation example shows the accuracy and effectiveness of the algorithm, which provides a new method for the accurate calculation of leakage current in distribution network.
