Description

Wind wave fusion power generation platform and anti-overturning rapid balancing system
Technical Field
The utility model relates to the technical field of renewable energy source utilization, in particular to a wind wave fusion power generation platform and an anti-overturning rapid balancing system.
Background
The wind energy is generated under the action of air pressure gradient due to unbalanced pressure in the atmosphere caused by uneven heating of all parts of the earth surface by solar radiation, namely, the kinetic energy generated by air flow is generally shielded by no barrier at sea, the wind speed is higher than that of the land, the wind shear is smaller, the turbulence intensity is small, the stable leading direction exists, the annual utilization period is long, the available wind energy at the sea 10km offshore is 2-3 times that of the land, in addition, the offshore wind power does not occupy land resources, and is close to the electricity load center for coastal use. The coastline of China is 18000 kilometers in length, islands are numerous, huge offshore wind power resources are reserved, and the total reserve of 10m high wind power resources in deep-line sea areas such as 50m offshore areas of China is estimated to be about 8.83 x 108kW, and the technical development amount is 5.70 x 10 8 The development potential of wind power in the deep sea area is more unlimited in kW.
For a semi-submersible platform type floating fan, the gravity center design is lower than a floating center, the floating body has self-stabilizing property, the water plane is smaller, so that the wave load is smaller, but the wind tilting moment easily causes larger platform pitching under the rated wind speed due to the higher elevation of the top wind wheel. According to the inquiry of the working characteristic parameters of the floating fan at home and abroad, the maximum inclination angle of the floating fan in the working state is generally required to be less than or equal to 10 degrees, and the maximum inclination angle in the limiting working state is generally required to be less than or equal to 15 degrees. The wave and wind acting together on the floating wind turbine platform can cause the floating wind turbine base body to be subjected to larger load, and meanwhile, the base body is caused to be in a larger overturning danger, and the floating wind turbine is in an abnormal working state in the state. The traditional fan floating foundation stability design generally adopts a method for reducing the waterline area, increasing the space between upright posts of a semi-shallow floating foundation, reducing the center of gravity of a platform or improving the floating center of a floating body to increase the anti-overturning restoring moment, but the method often brings about that the floating body structure is subjected to larger bending moment load, and higher requirements are put forward on the strength design of a semi-submersible platform; and secondly, the gravity center is adjusted by adjusting the ballast water distribution so as to change the moment distribution and adjust the inclination angle, but the response of the method is lagged, and the adjusting speed is low. The area of the south China sea area is wide, the wave and wind power resources are rich, the water depth is deep, the ocean environment is severe, typhoons are frequently generated, the response amplitude of the shaking motion of the floating wind wave fusion platform is more severe under extreme sea conditions, and the power generation efficiency and the safety of the floating fan are seriously affected. Therefore, how to design the floating type shaking response amplitude reduction is a key technology for designing the deep-open sea floating type wind wave fusion platform.
The utility model patent number 202320776671.1 discloses a wave energy floating type offshore wind turbine foundation type which mainly comprises a floating body, a central shaft tube, a connecting rod piece, a steel frame, a power generation device, an anchor chain, a tension leg structure and the like. The bottom of the central shaft tube is provided with the tension leg structure, and the floating body basically only performs heave motion around the central shaft tube under the action of waves and water flow, so that horizontal motion is not generated, the overturning effect of the waves and the water flow on the fan foundation is reduced, and the overall stability of the fan foundation is improved.
However, in the comparison document 1, the adopted central tube vibration water column wave energy device and vibration water column compressed air do work, the central Guan Zhen dynamic water column wave energy device can reduce the overturning effect of waves and water flow on a fan foundation, is passive and has low response speed, and the gravity center is adjusted by adjusting the ballast water distribution so as to change the moment distribution and adjust the dip angle, but the method has the advantages of lag response and low adjustment speed, is not suitable for deeper water depth, and is also used in the conditions of severe marine environment, typhoon frequently occurrence and extreme sea.

Namely, in the utility model, wave energy is captured by the up-and-down movement of the wave-absorbing floating body on the semi-submerged upright post; because a plurality of hydraulic components are arranged between the wave-absorbing floating body and the upright post, the effect of converting wave energy (kinetic energy) into hydraulic energy is realized.
In detail, in the utility model, wave energy is captured by the up-and-down movement of the wave-absorbing floating body on the semi-submerged upright post, and meanwhile, the impact force of waves on the floating fan base body is converted into the up-and-down vertical movement force of the wave-absorbing floating body, so that the wave load of the waves on the floating fan base body is reduced; secondly, because a plurality of hydraulic components are arranged between the wave-absorbing floating body and the upright post, and a far-distance force arm exists between the wave-absorbing floating body and the center of the floating fan, the floating force of the wave-absorbing floating body in waves can be rapidly increased or reduced by adjusting the PTO hydraulic damping (comprising back pressure adjustment and hydraulic cylinder quantity adjustment) between the wave-absorbing floating body and the upright post on the semi-submerged upright post, so that the state of a fan main body platform is rapidly controlled through the action of the floating force and the force arm, and the capsizing under extreme sea conditions is prevented.
In some embodiments of the present utility model, the platform rapid balance control system comprises at least three hydraulic assemblies 6, and the hydraulic cylinders 7 of the hydraulic assemblies 6 are communicated with an energy conversion system through pipelines, and the energy conversion system comprises a plurality of energy storage tanks. Preferably, the plurality of accumulator tanks includes at least one low oil pressure accumulator tank 10 and a plurality of high oil pressure accumulator tanks 13;

In some embodiments of the utility model, the rapid platform balance control system comprises a platform dip meter, a telex system and a hydraulic control system;
the platform inclinometer is arranged on the floating fan 14 and is used for adjusting the inclination angle so as to adjust the damping difference of the oscillating buoy type wave absorbing floating body.
In detail, setting the damping of the PTO refers to adjusting the number of hydraulic cylinders and the high oil pressure level behind the hydraulic cylinders, because for the wave energy device the force that impedes his movement can be referred to as damping force, it is by adjusting this damping force that the wave energy device wave absorbing float (the conical float moving up and down along the upright) will respond differently in the wave, in extreme cases it may correspond to a part of the fan base if the damping is large enough, at this time it will receive the maximum buoyancy, whereas if the damping is small enough it will receive the minimum wave force to move relative to the wave, thus always keeping the wave constant to the draft of the wave absorbing float, i.e. the wave absorbing float will not produce vertical buoyancy to act on the fan base at this time. Damping is adjusted so that the wave-absorbing floating bodies of the three upright posts fluctuate between the floating forces between the two extreme positions.
In the utility model, wave energy is captured by the up-and-down movement of the wave-absorbing floating body on the semi-submerged upright post, and meanwhile, the impact force of the wave on the floating fan matrix is converted into the up-and-down vertical movement force of the wave-absorbing floating body, so that the wave load of the wave on the floating fan matrix is reduced; secondly, because a plurality of hydraulic components are arranged between the wave-absorbing floating body and the upright post, and a far-distance force arm exists between the wave-absorbing floating body and the center of the floating fan, the floating force of the wave-absorbing floating body in waves can be rapidly increased or reduced by adjusting the PTO hydraulic damping (comprising back pressure adjustment and hydraulic cylinder quantity adjustment) between the wave-absorbing floating body and the upright post on the semi-submerged upright post, so that the state of a fan main body platform is rapidly controlled through the action of the floating force and the force arm, and the capsizing under extreme sea conditions is prevented.
In the utility model, wave energy captured by the wave absorbing floating body is converted into hydraulic energy mainly by adopting an oscillation float type wave energy capturing working principle and a hydraulic energy conversion mode.
A point of the edge of the top of the semi-submerged upright 4 is set as a point B, and a point above the wave-absorbing floating body 3 is set as a point A, wherein the point A and the point B are connection points of the hydraulic cylinder 7 with the wave-absorbing floating body 3 and the semi-submerged upright 4 respectively.
In the using process, under the action of waves, the wave-absorbing floating body 3 moves vertically along the semi-submerged upright post 4, meanwhile, the hydraulic cylinder 7 is driven to move between the point A and the point B, when the wave-absorbing floating body 3 moves upwards, the pressure between the points AB tends to be compressed, the hydraulic cylinder 7 needs to press oil in the cylinder body into the high oil pressure energy storage tank 13, and under the action of the high oil pressure energy storage tank 13, different grades of oil pressure are selected by combining the multidirectional conversion hydraulic control servo valve 17;
when the wave-absorbing floating body 3 moves downwards, the parts between the parts AB tend to stretch, and at the moment, the low-oil-pressure energy storage tank 10 is injected into the hydraulic cylinder 7;
repeatedly, under the action of waves, the wave-absorbing floating body 3 moves up and down to drive the hydraulic cylinder 7, so that wave energy of waves captured by the wave-absorbing floating body is converted into high-oil hydraulic energy.
In this way, the kinetic energy of the wave-absorbing floating body 3 can be converted into hydraulic energy, and the hydraulic cylinder 7 is placed above the water surface, so that the situation that the hydraulic cylinder 7 is easily corroded by seawater under water is avoided.
In addition, in the utility model, the rapid platform balance control system is used for realizing the anti-overturning effect, and the structure of the utility model is combined with the following detailed description:
the platform rapid balance control system comprises a platform dip angle measuring instrument, an telex system and a hydraulic control system; the platform dip angle measuring instrument is used for adjusting dip angle so as to adjust the damping difference of the oscillating buoy type wave absorbing floating body.
In the utility model, a platform dip meter is arranged on a floating fan 14, and the damping of a stand column wave-absorbing floating body 3 is adjusted by adopting a control strategy according to the platform dip meter on the floating fan 14; the control strategy is to adopt PID control, form control deviation according to given value and actual output value, form control quantity by linear combination of proportion, integral and derivative of deviation, and control the controlled object.
Damping of the wave-absorbing floating body 3 is mainly reflected in resistance force applied to push all hydraulic cylinders 7 to move when the floating body moves, and the damping force mainly comprises the number of the hydraulic cylinders 7 and the high oil pressure level behind the hydraulic cylinders 7; after the damping of the wave-absorbing floating body 3 is adjusted, the inclination angle of the floating fan 14 is monitored again, and feedback is completed. The method comprises the steps of setting a plurality of oil pressure energy storage devices with different grades in a wave energy device, and starting different oil pressures and the number of hydraulic cylinders to adapt to the impact load of waves according to different wave grades.
The principle of correcting the inclination angle of the platform by adjusting the damping of the wave-absorbing floating body is shown in figure 5, when the wave-absorbing floating body 3 is in a low damping state, the damping is smaller, the motion amplitude of the floating body is larger, the motion response is faster, and the floating force of the wave-absorbing floating body 3 to the upright post is smaller; similarly, when the wave-absorbing floating body 3 is in a high damping state, the motion amplitude of the floating body is smaller, the motion response is slower, the buoyancy of the wave-absorbing floating body to the upright post is larger, and in a limit state, the damping force of the wave-absorbing floating body is large enough, so that the buoyancy of the wave-absorbing floating body submerged in water is the maximum buoyancy.
Therefore, the damping of the wave-absorbing floating bodies of the stand columns of the platform can be controlled through the anti-overturning rapid balancing system according to the inclination angle of the platform, and the inclination angle adjustment of the platform can be rapidly realized by means of the buoyancy of the wave-absorbing floating bodies.
All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
