摘要
城市轨道交通系统中,地铁列车会频繁启停,在启动时会消耗大量电能,而在制动时产生的能量约占牵引能耗的40%~50%。为了充分利用地铁制动能量及稳定直流接触网电压,逆变型地铁能量回馈系统得到广泛应用。通过对比逆变型地铁能量回馈系统的控制策略,发现直流电压偏差控制的效果明显优于单纯的功率控制,可更好地实现稳定直流接触网电压。
In the urban rail transit system,subway trains will start and stop frequently,and will consume a lot of electric energy when starting.The energy generated during braking accounts for 40%~50%of the traction energy consumption.In order to make full use of subway braking energy and stabilize DC catenary voltage,inverter type subway energy feedback system is widely used.In this paper,through the comparative analysis of the control strategies of the inverter type subway energy feedback system,it is found that the effect of the DC voltage deviation control is obviously better than the simple power control,which can better achieve the purpose of stabilizing the DC catenary voltage.
