The invention discloses an undisturbed switching method for a marine hybrid power system, which is based on the marine hybrid power system comprising a diesel engine host, a clutch, a gearbox, a frequency converter and an asynchronous motor, and the frequency converter monitors the state of each device through a PLC (Programmable Logic Controller); according to the invention, through accurate control and strategy, current and voltage abrupt changes in the switching process are effectively reduced; through the smooth control process, the control mode is gradually adjusted according to the states of other devices in the monitoring switching process, additional mechanical impact and thermal impact on the devices are reduced, and the service life of the devices is prolonged.
本发明公开了一种船用混合动力系统无扰动切换方法,基于包含柴油机主机、离合器、齿轮箱、变频器和异步电机的船用混合动力系统,变频器通过PLC控制器监测各设备状态;本发明通过精确的控制和策略,有效减少切换过程中的电流、电压突变;本发明通过平滑的控制过程,根据监测切换过程中其他设备状态逐步调整控制方式,减少了设备额外受到的机械冲击和热冲击,延长设备的使用寿命。
