随着钢铁工业的发展,电弧炉单台容量不断增加,在电力系统中造成大的冲击,致使波形畸变,产生高次谐波,从而给电力系统,通讯设施和电气设备带来危害。高次谐波的危害也越来越引起人们重视。目前,我国正加强对谐波的测试研究,已着手制定谐波和电压闪变的标准,并加快无功静止补偿装置的研制步伐。 With the development of the iron and steel industry, the single capacity of electric arc furnace is increasing, causing a big impact in the power system, resulting in distortion of the waveform and generation of higher harmonics, thereby damaging the power system, communication facilities and electrical equipment. Harm of higher harmonics is also attracting more and more attention. At present, our country is strengthening the testing of harmonics, and has started to set the standard of harmonic and voltage flicker, and speed up the pace of development of reactive static compensation device.
