基于新能源接入的直流牵引供电系统
摘要：
本发明提供一种基于新能源接入的直流牵引供电系统，该基于新能源接入的直流牵引供电系统包括：至少两个牵引变电电路，至少两个牵引变电电路并联设置；每一个牵引变电电路均包括太阳能板和升压电路；其中，太阳能板与升压电路的第一端连接；升压电路的第二端与车辆电能的输入端连接；升压电路用于对太阳能产生的直流电压的电能进行升压处理，得到预设直流电压的电能，并将预设直流电压的电能输入至车辆电能的输入端。本发明提供的基于新能源接入的直流牵引供电系统，降低了城市轨道交通的运营成本。
摘要（英）：

The invention provides a new energy access-based DC traction power supply system. The new energy access-based DC traction power supply system comprises at least two traction power transformation circuits, wherein the at least two traction power transformation circuits are arranged in parallel, each traction power transformation circuit comprises a solar panel and a boost circuit, the solar panel is connected with a first end of the boost circuit, a second end of the boost circuit is connected with an input end of vehicle electric energy, and the boost circuit is used for boosting electric energy of a DC voltage generated by solar energy to obtain electric energy of a preset DC voltage and inputting the electric energy of the preset DC voltage to the input end of the vehicle electric energy. With the new energy access-based DC traction power supply system provided by the invention, the operation cost of urban rail transit is reduced.
