Abstract

The invention relates to a power control system and a power adjustment method for a drag suction dredger, and belongs to the technical field of dredging engineering. The power control system for the drag suction dredger comprise a power calculation, analysis and control unit, a middle / low-voltage power station, a generator, a dredging equipment signal acquisition unit, a propelling device signal acquisition unit and a power supply mode control unit. The power adjustment method for the drag suction dredger comprises the following steps that: the middle / low-voltage power station, the generator,the dredging equipment signal acquisition unit and the propelling device signal acquisition unit respectively acquire digital signals and equipment state signals of the middle / low-voltage power station, dredging equipment and a propelling device; and the power calculation, analysis and control unit performs processing and analysis calculation on the acquired signals to determine the total power required for dredger construction. The system configures a power supply mode automatically to keep the high-efficiency dredging operation of the drag suction dredger. The system and the method have theadvantages of simple structure, automatic control, reasonable power distribution, intelligent operation, high dredging efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of dredging engineering, in particular to a power control system and a power adjustment method of a trailing suction dredger. Background technique [0002] The power control system and power adjustment method of a trailing suction dredger are important control systems to ensure the dredging construction of a trailing suction dredger. The conventional dredger power management system mainly has the functions of remote control start and stop of generator sets, automatic grading and unloading, automatic unloading and other functions, and detects the ship power station. When the load of the ship exceeds the rated power of the main engine and power station, the power management control system automatically Limit / reduce the power used by ship equipment to ensure the safe operation of generators and power stations. [0003] With the development of modern shipbuilding technology, frequency conversion speed regulati...
