摘　　要：钢铁冶金企业为了降低碳排放,促进产业转型升级,在生产过程中大幅提高新能源的使用占比。但新能源在使用时容易出现电压波动、电能利用效率低、负序分量以及谐波等问题。因此,研究采用无功补偿技术和动态同步信号构建了动态同步无功补偿装置,用以优化电能质量。实验表明,该装置能够有效降低谐波电压含有率和谐波电流值,将电能利用率提升12.8%,废钢冶炼比例提升5.1%,而吨钢可比能耗下降22.94 kgce/t。该装置的应用使得废钢收得率提升8%,氧气消耗量下降15 m^(3)/t,功率因数从0.84上升至0.99。由此可得,动态同步无功补偿装置能够有效提高供电系统的稳定性,确保设备的安全运行,降低废钢冶炼成本,减少碳排放。To reduce carbon emissions and promote industrial transformation and upgrading,steel and metallurgical enterprises have significantly increased the proportion of new energy use in the production process.However,new energy sources are prone to voltage fluctuations,low energy utilization efficiency,negative sequence components,and harmonics during use.Therefore,a dynamic synchronous reactive power compensation device was constructed using reactive power compensation technology and dynamic synchronous signals to optimize power quality.The experiment shows that the device can effectively reduce the harmonic voltage content and harmonic current value,increase the electricity utilization rate by 12.8%,increase the scrap steel smelting ratio by 5.1%,and reduce the comparable energy consumption per ton of steel by 22.94 kgce/t.The device increased the scrap steel yield by 8%,reduced oxygen consumption by 15 Nm^(3)/t,and increased the power factor from 0.84 to 0.99.From this,it can be concluded that the dynamic synchronous reactive power compensation device can effectively improve the stability of the power supply system,ensure the safe operation of equipment,reduce the cost of scrap steel smelting,and reduce carbon emissions.
