An integrated control device for marine flywheel energy storage and anti-rolling

Abstract

The invention discloses an energy storage and stabilization integrated control device of flywheels for a ship. The energy storage and stabilization integrated control device comprises a forward flywheel, a backward flywheel, a forward flywheel controller, a backward flywheel controller, a system controller, an attitude sensor, a supercapacitor, a solar controller, a solar panel, a bidirectional inverter, an alternating current power supply / load, a bidirectional direct-current converter and a direct current power supply / load. By adopting a forward-backward flywheel structure, energy flows in the two flywheels in the stabilization process, and required external energy is extremely-low; when the ship steers, generated moments are mutually offset, so that the pitching is avoided, and driving resistance is prevented from being increased. A solar cell is utilized to generate power and the power is stored in the flywheels, so that the power can be supplied to the ship for performing stabilization control in a state that a ship main engine is not started; the flywheels are adopted to store energy, so that no secondary pollution is caused; the service life reaches 20 years or longer, and the safety and the reliability are guaranteed; a traditional storage battery is used as an emergency power supply, and the service life of the traditional storage battery is about three years; besides, a lithium battery has explosion hazard.

Description

technical field [0001] The invention relates to a marine dual-flywheel energy storage and anti-rolling integrated control device, which belongs to the technical field of ship control. Background technique [0002] The swaying of the ship has a great influence on the comfort and safety of the ship and the economy of the route. Generally, roll is the most likely to occur on a ship, and the roll has the largest swing amplitude, which has the most serious impact on the crew on board. Therefore, gyro precession anti-rolling devices are widely used in small ship systems. [0003] When the gyro stabilizer is working, the gyro rotor must first be accelerated to a very high speed by driving the motor. Usually, in order to reduce the resistance, it is necessary to pump a vacuum in the gyro. Then, through a hydraulic or electric drive system, the axis of the gyro rotor is driven to rotate back and forth around the horizontal axis of the ship, thereby generating a lateral gyro moment t...

AI Technical Summary

Problems solved by technology

Therefore, if the rolling period is long, the precession angular velocity must be reduced, so the anti-rolling effect will be limited

[0011] When the ship turns, the gyro stabilizer will generate a pitching moment to cause pitching, which is an undesirable effect, which not only makes the crew uncomfortable, but also causes additional driving resistance
