The invention provides a double-bus subway vehicle air conditioner load shedding control method which comprises the following steps: designing an existing AV380V bus into double buses, namely a first bus and a second bus; the TC1 vehicle SIV and the TC2 vehicle SIV are mounted on the first bus at the same time, and the M1 vehicle SIV and the M2 vehicle SIV are mounted on the second bus at the same time; the first bus and the second bus are connected in parallel through a bus contactor of the M1 vehicle; and two air conditioning units of each section of vehicle are mounted on the first bus and the second bus respectively, and air conditioner load shedding control logic is designed in combination with the states of bus contactors. According to the technical scheme, the technical problems that due to faults such as AC380V bus short circuit, a vehicle loses AC380V power supply, and air conditioner load shedding is controlled when a bus contactor breaks down are solved, the situation that the air conditioner is not subjected to load shedding or is not subjected to load shedding is avoided, the utilization efficiency of air conditioner equipment is improved, the comfort level of passengers is increased, and the service life of the passengers is prolonged. The SIV overcurrent fault is reduced, and the vehicle operation efficiency is improved.
本发明提供一种双母线地铁车辆空调减载控制方法,包括:将现有AV380V母线设计为双母线,分别为第一母线和第二母线;将TC1车SIV和TC2车SIV同时挂载在第一母线上,M1车SIV和M2车SIV同时挂载在第二母线上;将第一母线和第二母线通过M1车的母线接触器实现并联;将每节车两台空调机组分别挂载在第一母线和第二母线上,并结合母线接触器状态,设计空调减载控制逻辑。本发明技术方案解决了因AC380V母线短路等故障导致车辆损失AC380V供电以及在母线接触器故障时对空调减载的控制的技术问题,避免了空调该减载不进行减载和不该减载进行减载情况的发生,提升了空调设备的利用效率,增加了乘客舒适度,降低了SIV过流故障发生,提升车辆运营效率。
