Problems solved by technology

In addition, for engineering ships, the torque required by the propeller and its reverse resistance during the reversing process are closely related to the ship's speed, the angle between the course and the flow direction, and sea conditions at that time. There will be a big difference in the fuel consumption of engineering ships

Embodiment Construction

[0013] In order to make the structural layout, implementation process and beneficial effects of the system of the present invention more clearly displayed, further explanations will be made below in conjunction with relevant diagrams.

[0014] An oil-electric hybrid reversing control system suitable for engineering ships such as figure 1 As shown, the bridge reversing control system estimates the reversing resistance of the ship according to the actual sea conditions and the actual reversing speed of the ship, and then compares it with the predetermined resistance to select which reversing mode to use, and then controls the main propulsion unit and the electric reversing control unit through signal connection The two are respectively connected to the diesel engine and the reversing motor through signal control; the two ends of the engine are respectively provided with No. 1 clutch 1 and No. 2 clutch 2; wherein No. 1 clutch 1 is connected to the gearbox, and then connected to th...

Abstract

The invention provides a gas-electric hybrid reversing control system applicable to an engineering ship, and belongs to the technical field of ship power. The hybrid reversing control system comprises three ship reversing modes including a pure electric reversing mode, a diesel-power charging mode and a diesel-electric hybrid mode, and is composed of a bridge reversing control unit, a main propulsion control unit, an electric power reversing control unit, an engine, a clutch, a gear box, a propeller, an alternating-current and direct-current bus, an AC / DC rectifier, an inverter, a lithium battery energy storage unit and a reversing electromotor. According to the gas-electric hybrid reversing system, the ship reversing mode can be determined according to different reversing speeds and different degrees of ship reversing resistance under windy and wavy sea conditions, so that load fluctuations and fuel consumption increase caused by changeable working conditions in the reversing process are restrained effectively; and meanwhile, the reversing maneuverability and reversing capability of the engineering ship can be improved effectively through the application of different reversing modes.

Description

technical field [0001] The invention relates to an oil-electric hybrid reversing control system suitable for engineering ships, belonging to the technical field of ship power. Background technique [0002] At present, the domestic and foreign research fields on the oil-electric hybrid ship power system are more focused on the process of the ship's forward driving, and the research and application of the ship's hybrid sailing in the reverse state is still very rare. In the course of daily engineering practice, there are often some engineering ships that frequently use reversing conditions to carry out related operations, such as port tugboats carrying out reversing towing operations on the towed ships, and ships traveling on the opposite bank in inland rivers frequently drive forward and reverse without turning around The situation of going back and forth between the two sides of the strait and so on. Therefore, it is very necessary to add the oil-electric hybrid mode for th...
