The response of unit 50 to incident waves will depend upon, and to a great extent can be controlled by, the physical properties of the unit as, for example, the length of the yoke and raft; overall raft length; beam of the raft; mass of the raft; moment of inertia of the raft; impedance represented by power conversion equipment, hinge friction and hydrodynamic quantities such as added mass and damping. DESCRIPTION OF THE PREFERRED EMBODIMENT Unit Deployment Referring initially to FIGS. Thus, the voids and walls of the upper layer possess geometries designed to facilitate their lateral distribution of downward forces imparted to a very localized, and relatively small, central portion of the upper surface of the flotation module. 12. Power can be collected at a central control point to transform from onboard electrical generation levels to high voltage transmission over the longer distance to shore, thereby reducing line losses and increasing the economic efficiency of the system.

As previously described, the power generation system 10 includes an array 20 of units 50 deployed about the central transmission platform 14 as shown in FIGS. Instantaneous wave height and period can be defined for any segment of the record as shown in the referenced figure. While a preferred embodiment of the invention has been shown and described, modifications thereof can be made by one skilled in the art without departing from the spirit of the invention. 6. The power extraction device incorporates a control element that allows the power extraction impedance to be varied for maximum power extraction efficiency, thereby allowing maximum efficiency of power generation over short invervals of time. The power absorption efficiency of unit 50 is increased by increasing the moment of inertia to match more closely the response function to the spectral density function. The parameters listed define the wave configuration of unit 50 and in particular raft 70. The design process is one of examining the effect of each of the parameters on the unit response function operator and selecting that configuration that provides the most efficient system 10. Initially a configuration is selected for testing where the length of the raft is one-half the average wave length for the wave field, allowing a large amplitude of pitch, and the length of the yoke is one-fourth the average wave length.

The physical parameters of unit 50 are selected to maximize the power absorbed per the structural size of the unit such that the most economical system is realized. The label on the ordinate, response function R(f), given in kilowatts per meter squared, is the power absorbed by the unit. The floats are connected together by hinges as to form what is defined as a “Hagen” array. Crujido de rodilla sin dolor . 11. Power can be transmitted through the mooring system in a form that allows 360 degrees rotation of the array. Array 20 will generate a maximum of 60 megawatts of electricity and distribute approximately 180 gigawatt-hours of useful energy annually. Wave energy is absorbed by the hydraulic actuators which are responsive to the relative motion between the yoke and raft in such a way that the relative motion is employed to transfer energy to a hydraulic system.

The illustrated flotation module 260 floats adjacent to the surface 261 of a body of water. By creating and/or utilizing an inertial mass with an average density close to, and/or only slightly greater than, that of the water in which the embodiment floats, the mass of the inertial mass can be relatively great while its net effective weight can be relatively low (since the surplus in its weight over that of the water which it displaces is relatively small). A described above, waves in the real sea environment are made up of a complex mixture of waves which are described by the power density spectrum. As is hereinafter described in more detail, this is accomplished by determining the spectral density function of the typical waves for that region and varying the physical parameters of unit 50 to obtain an optimum response function of unit 50 to the typical waves making up the wave field.

The response function of the unit 50 is the power absorption measured at the hydraulic actuator as a function of frequency. Greater control of the natural frequency is possible by varying the moment by hull shaping. The buoy mass is sufficiently large to restrict the energy transmitted to the buoy to be less than 5% of the total useful energy absorbed by unit 50. The buoy requires sufficient buoyancy to hold up the weight of the frame and cylinder of buoy assembly 300. The cylinder contains water for added mass. Each absorber unit 50 includes one or more buoyant members such as floats or rafts 70 connected to a mooring means 300 by means of a mooring yoke 60 and allowed to move in response to the motion of the waves such as wave 22 in wave field 12. The extracted energy is converted onboard the raft 70 into useful energy such as electrical energy.

3. The mooring means 300 includes a large buoy 302 ballasted to represent a resistance to the vertical forces imposed on mooring means 300 by yoke 60. Across the hinge line 90 at the raft-yoke interface, conversion means 110 mounted on raft 70 and yoke 60 are driven by the relative motion between yoke 60 and raft 70. Conversion means 110 includes hydraulic actuators 120 which displace hydraulic fluid into accumulators 162 which are pressurized.

After the optimization of raft 70 and yoke 60, the mooring buoy 300 motions under the influence of the power train and mooring forces are considered. Como quitar dolor de rodilla . 367. This would tend to create a significant opposing torque that would tend to preserve a horizontal alignment of the buoy and prevent its rotation so as to maintain the relative position of the inertial mass 361 along the buoy’s inertial mass alignment axis.

FIG. 10 is a sectional view of the mooring buoy of the mooring system of FIG. The valve’s top plate 2803 covers, and/or potentially covers, two holes or orifices, e.g. In this embodiment, inertial mass 581 can have net weight greater than that of restoring weight 578. In an equilibrium configuration, e.g.

The bow and stern have been raked to increase the deck length so that the deck 140 is longer than the hull 209 at the waterline. 20. The hull 209 has a sloped or rake bow and stern at 207, 208 respectively to reduce the drag of water due to the velocity of the hull and to avoid loss of energy by making waves. Compartments 200, 202 extend above deck 140 and over the waterplane line of hull 209 to enhance the movement of inertia. U.S. Pat. No. 3,758,788 discloses an energy conversion system where buoyant structures are connected together by pivotal structures and bellows which are activated by movement between the buoyant structures.
