本文针对府谷某煤化有限责任公司拟建设的2×33000kVA硅铁电炉,提出了合理的无功补偿设计方案并予以实现。由于硅铁电炉的功率因数较低约为0.70左右,且在生产时会产生少量的高次谐波,因此合理配置硅铁电炉的无功补偿装置是极为重要的。本文按电压等级分类针对目前的高压并联电容补偿装置、中压并联电容补偿装置、低压并联电容补偿装置的优缺点进行比对,最终为该公司确定了合理的无功补偿设计方案。
Aiming at the 2 × 33000 kVA ferrosilicon furnace proposed by Fugu Coalification Co., Ltd, a reasonable design scheme of reactive power compensation is proposed and implemented. Due to the low power factor of ferrosilicon furnace of about 0.70, and will produce a small amount of higher harmonics in the production, it is extremely important to properly configure the reactive power compensation device of ferrosilicon furnace. According to the voltage level classification, this paper compares the advantages and disadvantages of the current high-voltage shunt capacitor compensation device, medium voltage shunt capacitor compensation device and low voltage shunt capacitor compensation device, and ultimately determines the reasonable reactive power compensation scheme for the company.
