牵引变电所电容补偿容量及补偿方式对电压的影响

The Influence of Capacitance Compensation Capacity and Compensation Modes on Voltage in Traction Substation

指出了目前许多铁路牵引变电所仍采用固定无功补偿,阐述了补偿容量是在95%最大概率负荷条件下确定的,在大负荷的情况下不满足功率因数0.9的要求。计算了最大负荷方式下的电容补偿容量,并分析了不同补偿容量、不同补偿方式下的电压偏差情况。

Fixed reactive compensation is still adopted in many railway traction substations. It is elaborated that compensation capacity is confirmed under the condition of 95% peak load probabilistic, which doesn＇t satisfy the request of power factor 0.9 in peak load. This paper calculates the capacitance compensation capacity in the peak load, and analyses the deviation of supply voltage with different compensation capacity and modes.
