Poor energy, wave energy etc., wherein wave energy distribution the most extensively, reserves it is extremely abundant, energy-flux density height, in offshore and offshore
Qu Junke is obtained.
Wave energy generating set relates generally to the conversion process three times of energy: level-one is converted to absorption wave energy and is converted to certain
The mechanical energy of kind carrier；Second level, which is converted to, to be transmitted the mechanical energy of level-one conversion by certain mechanical energy form and switchs to stable
Energy；Three-level, which is converted to, is ultimately converted to electric energy for mechanical energy by generator.According to mechanical energy in conversion process of energy
Form, wave energy generating set is generally divided into three kinds of forms: oscillaton water column type, more unrestrained formula, oscillating float type at present.Wherein shake
It swings float-type and is referred to as third generation wave energy generating set, directly act on absorption using the oscillating body and wave that float or flood
Wave energy, high conversion efficiency, because float size corresponds to, incident wavelength is smaller, and be otherwise known as an absorption plant, can be in difference
It works under depth condition (especially the depth of water be more than 40m greater coasting area), these features make oscillating floater become offshore area
A kind of type for having much prospect of wave energy exploitation.
It is by the floats that are placed in water of one or more as acquisition device that point, which absorbs wave energy acquisition device, using with float
The hydraulic device or mechanical device of son connection convert hydraulic energy or mechanical energy for the potential energy of wave and kinetic energy, and then drive
Electrical power generators.However, the power capture performance of oscillating floater and unsatisfactory, heave type oscillating floater Wave energy converter
Average energy capture width ratio be 16%, only when the intrinsic frequency of Wave energy electric generator and wave basic frequency are not much different,
Ideal capture power could be obtained near the frequency.Traditional one freedom oscillation float is linearly caught can system wave power conversion
Device energy conversion efficiency under the conditions of anti-resonance frequency is very low, and capture width ratio is smaller, inhales to the energy of place wave field
Receipts utilization rate is low, and the manufacturing cost of equipment and cable is relatively high.Since China's wave has, the period is short, wave height is small, it is close to flow
The features such as low is spent, tradition is difficult to obtain increasing structure size merely in a manner of obtaining higher energy transfer efficiency good
Effect.
