The embodiment of the invention discloses a double-wire system ground power supply network switching control method, relates to the field of aircraft power supply system design, and can enhance the reverse polarity fault detection and processing capability of a system, reduce the risk of short circuit of the system due to reverse polarity errors, and reduce the risk of accidents during conversion. Specifically, the positive electrode and the negative electrode of a ground power supply interface are respectively provided with contactors (contactor +/contactor-), and the pair of contactors are subjected to associated control, so that the safety when the ground power supply is put into a power grid can be effectively improved, and particularly, the reversed polarity fault detection and processing capability of the system is enhanced; the risk that the system is short-circuited due to reverse polarity errors is remarkably reduced, meanwhile, the two-wire system control strategy also guarantees stable conversion between power supplies of the power supply system in the state conversion process, and the risk that accidents occur during conversion is reduced.
本发明实施例公开了一种双线制的地面电源投退网控制方法，涉及飞行器电源系统设计领域，能够增强系统的反极性故障检测与处理能力，降低了系统因反极性错误而短路的风险，并且减小转换间发生意外的风险。具体在地面电源接口正极和负极分别设有接触器(接触器+/接触器‑)，通过对这一对接触器进行关联控制，可以有效提高地面电源投入电网时的安全性，特别是增强了系统的反极性故障检测与处理能力，显著降低了系统因反极性错误而短路的风险，同时，双线制控制策略也保障了状态转换过程中供电系统电源间的平稳转换，减小了转换间发生意外的风险。
