低压配电网降损中无功补偿技术的运用

Application of Reactive Power Compensation Technology in Low Voltage Distribution Network Loss Reduction

在电力行业追求高效、节能的大背景下,低压配电网降损中的无功补偿技术应运而生的。随着电力需求的不断增长,低压配电网的损耗问题日益突出,为提升功率因数、降低线损并改善电网的电压质量,采用静止无功发生器(Static Var Generator,SVG)和晶闸管投切电容器(Thyristor Switch Capacitor,TSC)等设备的混合补偿方案,并结合MATLAB仿真模型进行验证。SVG+TSC混合补偿方案进一步提升了电网性能,将电压波动范围降低到±1.5%,线损率降低到2.0%,并减少了350 kvar的无功功率。实验数据充分证明了无功补偿技术在优化电力系统运行、降低能耗方面的显著效果,为企业和区域发展带来了更大的经济效益。

Under the background of pursuing high efficiency and energy saving in power industry,reactive power compensation technology in low-voltage distribution network loss reduction came into being.With the increasing power demand,the loss problem of low-voltage distribution network is becoming more and more serious.In order to improve power factor,reduce line loss and improve the voltage quality of power network,a hybrid compensation scheme of Static Var Generator(SVG)and Thyristor Switch Capacitor(TSC)is adopted,which is verified by MATLAB simulation model.SVG+TSC hybrid compensation scheme further improves the power grid performance,reduces the voltage fluctuation range to 1.5%,the line loss rate to 2.0%,and reduces the reactive power of 350 kvar.The experimental data fully prove the remarkable effect of this technology in optimizing the operation of power system and reducing energy consumption,and bring greater economic benefits to enterprises and regions.
