以电气化铁道27.5kV侧电压损失计算电路为基础,对电气化铁道串联电容补偿装置容抗的选择范围进行了分析,对串补装置安装位置与最大提升网压的关系及其影响因素进行了研究,并对供电臂新设串补装置和新增串补装置的设置方案给出了建议。
Based on the voltage loss calculation circuit of 27.5kV side of electrified railway, the selection range of capacitive reactance of series capacitor compensation device for electrified railway is analyzed. The relationship between the installation position of series compensation device and the maximum increase of network pressure and its influencing factors are studied. And give a proposal for setting up a new series device of the power supply arm and a new series compensating device.
