标准摘要
[中文适用范围]： 本部分IEC 61000（技术报告）提供了非正弦条件下各种电功率量及其相互关系的定义，旨在明确功率因数的两个组成部分：由于基波频率下电压和电流之间的相位差引起的基波功率因数，以及由于电压和/或电流畸变引起的非基波功率因数。本报告仅适用于单相系统。本报告提供了以下三种情况的定义：电压和电流均畸变的一般情况（第5条）；假设电压为正弦且电流仅含谐波分量畸变的情况（第6条）；电压和电流均为正弦的特殊情况（附录A）。附录B提供了关于基波有功因子的信息，该因子用于描述设备作为负载或发电机的行为。 [外文原描述]： IEC TR 61000-1-7:2016(E) provides definitions of various electrical power quantities and the relationship between them under non-sinusoidal conditions, in order to give clear information on both components in the power factor: - the fundamental power factor, which is due to the phase difference between the voltage and current at the fundamental frequency, and - the non-fundamental power factor, which is related to the distortion of the voltage and/or current. This Technical Report is applicable only to single-phase systems.
