110 kV变电站增设无功补偿装置方案设计

Scheme Design of Adding Reactive Power Compensation Device in 110 kV Substation

中条动能110 kV变电站配电线路较多,平均月用电量在3000万kW·h,功率因数保持在0.91~0.92。为保证该站功率因数达0.95,从电容装置的安装位置、容量、电压、控制方式等角度进行分析,确定了补偿装置主要参数后,并对该站功率因数达到0.95后所产生的效益进行计算分析。

There are many distribution lines of 110 kV kinetic energy substation in Zhongtiaoshan,and the average monthly electricity consumption is 30 million kW.h/month,and the power factor remains at 0.91-0.92.In order to ensure that the power factor of the station can reach 0.95,this paper analyzes the installation position,capacity,voltage and control mode of the capacitor device.After determining the main parameters of the compensation device,the benefits generated by the power factor of the station reaching 0.95 are calculated and analyzed.
