氢燃料电池动车组氢动力系统能量控制单元关键技术

Key Technologies of Hydrogen Power System Energy Control Unit for Hydrogen Fuel Cell EMU

以某型氢燃料电池动车组的氢燃料动力系统能量控制策略为例,系统地论述了氢燃料电池动力系统的能量管理策略和故障诊断策略,并通过系统联调对启停机、加减载及能量管理等控制功能进行验证。验证结果表明,所提控制方案可实现对氢燃料电池动力系统稳定可靠的控制,且实时性和跟随度较好,能够满足整车应用要求。

Taking the hydrogen fuel power system energy control strategy of a hydrogen fuel cell EMU(electric multiple unit)as example,the energy management strategy and fault diagnosis strategy of hydrogen fuel cell power system is systematically discussed,control functions such as startup/shutdown,loading/unloading and energy management are verified through system joint commissioning.Results show that the proposed control scheme can realize stable and reliable control of the hydrogen fuel cell power system,and the synchronicity and following feature are relatively good,satisfying the application requirements for the whole vehicle.
