Abstract

The invention belongs to the technical field of marine diesel engines, and particularly relates to a marine diesel engine main propulsion control device which comprises a diesel engine assembly, a monitoring assembly and a propulsion assembly, the diesel engine assembly comprises a diesel engine body, and a diesel engine controller is arranged on the outer side of the diesel engine body; an oil supply pipeline communicated with the diesel engine body is connected to the side wall of the diesel engine body, and the input end of the oil supply pipeline is connected with an external oil tank. The output end of the diesel engine body is connected with a clutch, the output end of the clutch is connected with a motor, and the motor is connected with a propelling assembly through a reduction gearbox. The monitoring assembly comprises a monitor, and the monitor is connected with the diesel engine controller and the motor and used for monitoring the states of the diesel engine body and the motor. According to the method, the performance defect of single inversion is overcome by adopting a multi-step generalized inverse method, the position holding capacity of the dynamic positioning ship is improved, and the problem of propeller saturation in constraint thrust distribution is solved.

Description

technical field [0001] The invention relates to the technical field of marine diesel engines, in particular to a main propulsion control device for marine diesel engines. Background technique [0002] The marine diesel engine propulsion power module is mainly composed of single or multiple diesel engines, gearboxes, couplings, shaft motors and other equipment. Port operation tugboats driven by pure diesel engines have low thermal efficiency; based on the characteristics of port operation tugboat operations, the main engine is often in low-load conditions, and compared with the required power, fuel consumption and emissions are higher; oil energy costs are high, and emission pollution is large; it cannot meet Environmentally friendly development and air emission policy requirements, so hybrid power has become a new mainstream method. [0003] With the development and progress of society, higher technical requirements are put forward for the propulsion power module of marine ...
