The invention provides a transformer substation integrated charging station and a control method thereof. A voltage transformation system, a dynamic reactive power compensation device and a charging system compatible with various power supplies are arranged in the charging station. The dynamic var generator (SVG) arranged in the transformation system can not only compensate inductive reactive power, but also can compensate capacitive reactive power. DC voltage led out by the dynamic reactive power compensation device can be collected to a DC bus of the integrated charging station, so that each port connected with the bus is correspondingly configured to provide current input for a DC/DC converter of a charging pile, and a charging gun outputs a DC charging electric signal to charge an electric vehicle.
本申请提供一种变电站一体式充电站及控制方法。本申请的充电站内设置有变压系统、动态无功补偿装置,以及兼容多种电源的充电系统。本申请中,变压系统内所设置的动态无功补偿装置(static var generator,SVG),既可以补偿感性无功,也可以补偿容性无功。该动态无功补偿装置所引出的直流电压能够汇集至一体式充电站的直流母线,从而通过母线所连接的各个端口相应被配置为为充电桩DC/DC变换器提供电流输入,从而通过充电枪输出直流充电电信号实现对电动汽车进行充电。
