摘要
提出了交流采样技术中采样领界的选择原则。导出了交流采样频立与所考虑高次谐波之关系。按我国公用电网谐波含量限制,研究了交流采样频率对各谐波功率测量的影响。最后分析了交流采样技术的适用范围。
The adoption Principle of sampling frequency for alternating signals is proposed in this paper. The relation between sampling frequency and considered harmonic power is derived.Based on the limitation of harmonics content in China's power systems, the influence of sampling frequency for alternating signals on measurement of harmonic power is discussed. Finally the suitability of sampling technology for alternating signals is analyzed.
