【摘要】 针对郑州南牵引变电所功率因数异常过低的情况,本文根据统计电量和实测数据进行原因分析,指出长距离馈线上网电缆的容性无功对牵引变电所功率因数的影响,确定无功补偿电抗器的容量并计算理论补偿效果,阐述了一种利用电能质量分析仪记录数据分析电量和功率因数的方法,并分析了郑州东变电所电力负荷对馈线上网电缆容性无功的补偿作用。更多还原

【Abstract】 This paper aim at the abnormal situation that the power factor in Zhengzhou South traction substation is too low, and make an analysis of causes according to the statistical electricity quantity and measured data. This analysis points out that the capacitive reactive power of long-distance feeder network cable will make influence on the power factor of traction substation, due to this analysis, the paper determines the capacity of reactive power compensation reactor and calculates the theoretical compensation effect. The paper also provides a method to analyze the electric quantity and power factor based on monitored data by using power quality analyzer, and analyze the compensation effect of power load on the capacitive reactive power of feeder network cable in Zhengzhou East substation.更多还原
