Heave compensation method of the invention can also be provided to be realized with heave compensation system according to the present invention is utilized
Same or similar advantage and preferred embodiment.The present invention provides a kind of absorbing load descending motion potential energy to be stored in accumulator
With the Active Heave Compensation System in the case of super capacitor, this method comprises: motor, generator, secondary component, accumulator,
Two different compensating coefficient incisions drop under a load and rise in super capacitor, controller and dynamic coupling device, secondary component
Two kinds of working conditions of corresponding hydraulic pump or hydraulic motor are changed to be used to convert hydraulic energy.
A kind of energy-saving winch type Active Heave Compensation System, when load needs to decline to compensate ship to its motion state
When caused influence, 10 output signal of controller makes 5 left position of reversal valve work, and secondary component 6 is at this time with the work of hydraulic pump
The discharge capacity made characteristic, and reduce unidirectional variable pump 3, which makes it only, need to meet the leakage of system.It loads at this time in the presence of its gravity
It moves downward, becomes the power resources of system, the transform linear motion of load is that rotary motion drives secondary component by winch
(pump) 6 rotates, and exports high pressure oil, and by controlling the discharge capacity of oil return motor 9, the torque of generator 11 and the opening of proportioning valve 8 are big
It is small, change system back pressure, realize adjusting to 6 revolving speed of secondary component (i.e. loading speed), and by the gravitional force equivalent of load
Be converted to electric energy and hydraulic energy is stored in super capacitor 12, in accumulator 7.
When load needs to rise to compensate ship to influence caused by its motion state, reversal valve 5 works in right position,
Secondary component 6 is at this time with the working characteristics of hydraulic motor, power needed for 15 offer system of engine, and unidirectional variable pump 3 is defeated
High pressure oil out drives secondary component 6, promotes load.The output control signal of controller 10 changes the discharge capacity of unidirectional variable pump 3, from
And the revolving speed of secondary component 6 is controlled, reach compensation purpose.Meanwhile accumulator 7 discharges the liquid recycled when last decline compensation
Pressure oil, the high pressure oil driving oil return motor 9 of release and co-axial connected generator 11 rotate together, and generator 11 generates electricity,
Hydraulic energy is converted into electric energy and enters the recycling that dynamic coupling device 16 realizes energy.
As shown in Fig. 2, being the work flow diagram of energy-saving heave compensation system and method for the invention.Specific workflow
Journey is as follows, and after hull displacement changes, controller 10, which receives detection signal and provides, executes order, true by detection signal
Fixed load needs to decline compensation or rises compensation.If load needs to decline to realize compensation, reversal valve 5 is placed in left position,
At this point, secondary component 6 is equivalent to the working characteristics with hydraulic pump, load realizes decline to reach compensation mesh under the effect of gravity
, while secondary component 6 exports high pressure oil to accumulator 7 and oil return motor, and hydraulic energy conversion is stored in accumulator 7,
Load opening of the decrease speed by proportioning valve 8, the discharge capacity co- controlling of oil return motor 9.
Further, when controller 10 determines that load needs to rise to realize compensation by detection signal, reversal valve 5 is placed in the right side
Position work, secondary component 6 is equivalent to hydraulic motor at this time, and controller 10 gives unidirectional 3 signal of variable pump, exports high pressure oil, driving
Secondary component 6 is converted hydraulic energy to mechanical energy to promote load.Meanwhile 7 mesohigh of accumulator is stored in when loading decline
It can discharge, pushing generator works after oil return motor, and the electric energy of conversion enters dynamic coupling device 16 and waits motor 15
It dispatches next time, in this way, being achieved that the recycling of system gravitional force, has saved a large amount of resource.
