化工厂谐波分析与治理

Harmonic Analysis and Disposal in Chemical Plant

近年来变频器因为其驱动电动机系统节能明显、调节方便等特点在化工系统中得以越来越多的应用,但同时因为它非线性的工作方式产生的高次谐波给电网系统带来了一定的影响,对其他电气设备造成损害,其危害已不可忽视,在实际的谐波治理过程中,应因地制宜选择合适的谐波治理方案。

For the energy saving and easily adjust,there are more and more frequency converters applied in chemical plant,but nonlinear distortion bring too much high level harmonics to electric network,do harm to other electric equipment.We need to deal with harmonics for its hazard,there are several ways to handle,but in practice,we should choose the most effective and economical proposal.
