摘要
分析了低压配电网谐波的产生根源和危害,阐述了谐波的基本性质和测量方法,推荐采用数理统计的方法对谐波进行测量。采用加装无源电力滤波器、隔离变压器和有源谐波调节器等综合措施,有效抑制谐波的产生,减小影响范围,提高了系统运行稳定性,降低了电能损耗。
Analysis was made to tile generating root and harm of low-voltage power distribution network, describing the basic char- acter and measurement method of harmonic and recommending mathematical statistics method to carry out measurement for harmon- ic. Adoption of passive power filter, isolating transformer and active harmonic regulator etc synthetic measures effectively suppressed harmonics and reduced the area of influence, having raised the stability of system operation and reduced power energy loss.
