The invention provides an engine starting control method of a tandem type hybrid power system. The engine starting control method comprises the steps: a generator controller sends a starting instruction to a generator according to the starting instruction of a unit coordination controller; the generator controller controls the generator to drag the engine to reach a preset rotating speed at a preset dragging speed; the generator controller acquires working parameters when the engine reaches a preset rotating speed; and the generator controller determines that the engine is successfully startedaccording to the working parameters reaching the preset working parameters and controls the generator to be separated from the engine. According to the engine starting control method of the tandem type hybrid power system, the step of starting the engine through a starter is omitted, the cost of the tandem type hybrid power system can be reduced, and meanwhile the risk that the generator flames out the engine under pressure when the engine is started can be reduced.
本发明提供了一种串联式混合动力系统的发动机起动控制方法,包括步骤:发电机控制器根据机组协调控制器的起动指令向发电机发送起动指令;发电机控制器控制发电机以预设拖动速度拖动发动机达到预设转速;发电机控制器获取发动机达到预设转速时的工作参数;发电机控制器根据工作参数达到预设工作参数确定发动机起动成功,发电机控制器控制发电机与发动机分离。本发明的串联式混合动力系统的发动机起动控制方法取消了通过起动机起动发动机的步骤,可以降低串联式混合动力系统的成本,同时,可以降低发动机起动时发电机将发动机压熄火的风险。
