Problems solved by technology
At present, a small number of domestic ships have begun to adopt diesel-electric hybrid power devices, but the diesel-electric hybrid power devices involved can only operate in some of the above four modes, and most of the core equipment in the system are integrated by foreign manufacturers Supply
As for how to realize the automatic control of the parallel propulsion of the shaft motor and the diesel engine, it is even more difficult, and there is no corresponding real ship application so far.

Description
technical field [0001] The invention relates to ship power device technology, in particular to a ship diesel-electric hybrid power device. Background technique [0002] There are four main working modes of the diesel-electric hybrid power plant based on the application of PTO / PTI reversible shaft motor: one is that the diesel engine drives the propeller while driving the shaft motor to generate electricity (the motor operates in PTO mode, replacing the ship power station for the whole ship’s power supply) ; Second, when the diesel engine fails or low-noise navigation, the shaft motor is powered by the ship power station and runs in electric mode (ie PTI mode) to propel the ship to sail; third, when cruising at low speed, a diesel engine drives the propeller of the shaft system to run at the same time, Drive the shaft motor of this shaft system to run in PTO mode, supply power to the shaft motors of other shaft systems, and make them run in PTI mode, and then drive the propel...
