摘要
大量非线性、冲击性以及不对称负载设备广泛应用,产生的谐波引起电能质量指标恶化,干扰了电力设备及电气负载的正常运行。介绍了电网中产生谐波的电气设备以及谐波危害,对抑制谐波的措施进行了阐述,并针对化工企业广泛使用的变频器产生的谐波问题提出了应对措施。
A great deal of non-linear,impacting and asymmetric load equipment was applied so widely that the generated harmonics made power quality index deteriorated,interfering normal operation of power equipment and electric loads.Introduction was made to the equipment which generated harmonics in power grid and the harmonic harms.Measures were set forth to suppress harmonics.And counter measures were raised to solve the harmonic problem caused by widely-used inverters in chemical enterprises.
