Jiangyin Huaxin Steel Cable Co., Ltd. produces thick zinc-coated prestressed steel wire, stranded wire and other steel wire, bar steel, steel wire metal products and stainless steel sheet materials.
Power Quality Problem
In the production process, the harmonic content of the power grid is relatively large, the power quality is poor, and the original reactive power compensation equipment has poor effect and low power factor. Therefore, there is a need to control reactive power.
On-site passive harmonic filter was put into use, which compensated some reactive power and improved power factor, but the compensation effect was not obvious, and the power factor was still low after compensation.
On-site harmonic current is mainly 5th, 7th, 11th and 13th harmonic. After installation YTPQC-AHF and YTPQC-SVG, the THDi is reduced to below 5% and the power factor is increased to 0.99.
