The invention provides a power distribution method of an energy storage type rail train non-contact traction power supply system. The power distribution method comprises the steps of determining the coupling state of a primary side coil and a secondary side coil; when the coupling state is normal, before pulse width modulation is carried out in the train running process, obtaining the rectification output voltage of a power module PU, and starting the PU with the first ratio between 1 and a first ratio threshold value according to a preset power variation limit value; starting the PU of whichthe first ratio is between a second ratio threshold value and 1 according to the product of the first ratio and a preset power variation limit value; controlling the output power of the PU of which the second ratio is 1 and the third ratio threshold value according to a preset power variation limit value, and controlling the output power of the PU of which the second ratio is 1 to keep unchanged so as to carry out power distribution on each PU; and acquiring the required power of the system, and when the required power is not greater than the sum of the system power determined according to theoutput power of each PU and the power of the vehicle-mounted energy storage equipment determined through the fuzzy reasoning rule, ending the power distribution.
本发明提供了一种储能式轨道列车非接触牵引供电系统的功率分配方法,包括:确定原边线圈和副边线圈的耦合状态;当耦合状态正常时,在列车行驶中进行脉宽调制前,获取功率模块PU的整流输出电压,按照预设的功率变化量限值启动第一比值处于1与第一比值阈值之间的PU,且按照第一比值与预设的功率变化量限值的乘积启动第一比值处于第二比值阈值与1之间的PU;按照预设的功率变化量限值控制第二比值处于1与第三比值阈值的PU的输出功率,且控制第二比值为1的PU的输出功率保持不变,以进行各PU的功率分配;获取系统的需求功率,当需求功率不大于根据各PU的输出功率确定的系统功率与通过模糊推理规则所确定的车载储能设备的功率之和时,结束功率分配。
