Description
Technical field
The present invention relates to wave-energy power generation technical field, be specifically related to a kind of direct-drive type point that is applied to and absorb Wave energy generating system
Long secondary, short preliminary linear electromotor.
Background technology
Point absorbs Wave energy generating system and refers to the electricity generation system much smaller than wave wavelength of the floating float size for capturing energy,
This system is commonly divided into direct-driving type and non-direct drive type.The float of non-direct drive type system connects pneumatic system, hydraulic system or gear
The speed raising apparatus such as case, then reconnect rotary generator.The volume of non-direct drive type system is little, but its intermediate link is complicated, fall
The reliability of low system and conversion efficiency.Direct-driving type system float is directly connected to linear electric generator, it is not necessary to any intermediary agency.
This system structure is simple, improves efficiency and the reliability of system.Absorbed as the point of electromechanical transformation apparatus by linear electric generator
Wave energy generating system is that direct-drive type point absorbs Wave energy generating system.
It is said that in general, linear electric generator can be divided into the various ways such as single side type, double-flanged end, four limit types, cylinder type according to structure.
For ensureing the active wires length of cutting magnetic field, linear electric generator is frequently with long secondary, the structure of short primary.At direct-drive type wave
In energy electricity generation system, in order to ensure that under extreme sea condition, linear electric generator is not damaged, the rated power of linear electric generator is selected to be much larger than
Wave power under extreme sea condition, therefore under normal sea situation, in the case of linear electric generator is operated in far below rated power.Root
Theoretical according to Electrical Motor, in the case of actual power power is less than rated power, input power is the lowest, motor decrease in efficiency
The fastest so that the universal inefficiency of wave energy linear electric generator, such as the absorption wave of point of China's Research Institute 10kW
Energy electricity generation system, its long-term work is under the wave of 3kW, and the phenomenon of this " low load with strong power " causes linear electric generator to be changed
Efficiency is the lowest.In the most all kinds of wave energy generating set of same problem the most common.
Summary of the invention
It is an object of the invention to overcome existing absorption direct-drive type wave energy electricity generation system cathetus generator power unmatched scarce
Point, proposes a kind of linear electric generator for short primary long secondary linear electric generator primary.
Present configuration is reasonable, uses stagewise, blocking design, has the advantage that operational efficiency in broad power band is high.This
Invention can be used for an absorption direct-drive type wave energy electricity generation system.
Linear electric generator primary of the present invention includes stagewise primary stator core and stagewise armature winding.
The present invention, in the case of not increasing motor materials cost, carries out segmentation, by whole section of primary stator ferrum to primary stator core
The segmentation in vertical direction of core and armature winding, constitutes Multi-segment primary stator core unit and armature winding unit.Every section of primary is fixed
Sub-iron core unit is formed by silicon steel plate stacking, has recessed at primary stator core unit at uniform intervals towards secondary side
Groove, the groove opened is primary stator slot.The adjacent bossing between primary stator slot is primary stator tooth.Each
Section armature winding unit embeds in the primary stator slot of corresponding primary stator core unit, forms one section of primary unit.Each
Section primary unit all can be regarded as can the linear electric motor primary of independent operating.Simultaneously take account of the sinusoidal rule of wave motion displacement,
Every section of primary unit is the most symmetrical for initial point with secondary center, and the length of every section of primary unit is not
With, the length of the primary unit being positioned at secondary centre position is the longest, the length of the primary unit that distance secondary centre position is the most remote
The shortest.Two the primary unit windings being arranged symmetrically with along secondary centre control break-make by a set of power electronic devices.
The primary of linear electric generator of the present invention is divided into multiple primary unit: adjusts according to the size of actual wave and puts into the primary list of generating
Unit's number, thus the effective winding length of regulator generator and then change electromotor copper loss, it is achieved the adjustment of generator rating power,
Specific works principle is as following: conventional electric generators is in the case of electric machine structure parameter constant, and rated power will not change,
And its under nominal power efficiency the highest, reason is, in the case of motor winding, iron core, permanent magnet material size are fixing,
The absolute value of partition losses is basically unchanged, and when output power of motor reduces, loss accounts for the ratio of output and increases, and makes motor
Under less than specified operating mode, efficiency declines.And correlational study shows, in the equipment of direct-drive type low cruise, electromotor copper loss
Accounting is bigger.
The present invention is the structure of the short primary of the stagewise blocking for short primary long secondary linear electric generator, and linear electric generator is tied
Structure can use conventional linear electric machine structure, such as single side type, double-flanged end, four limit types, cast etc..Linear generator secondary level can use
Conventional linear motor secondary structure, secondary excitation uses permanent magnet excitation, and magnetic steel array can use N, S pole uniform intervals array
May be used without HALBACH array etc..Primary, secondary is wrapped with motor case, plays sealing or supporting role.Primary,
Secondary and casing collectively constitutes a complete linear electric generator.
Operation principle of the present invention and work process are as follows:
Direct-drive type point is absorbed Wave energy generating system and is moved up and down under the effect of wave buoyancy by floating float, drags with forever
The straight reciprocating motion in motor of the secondary of magnet produces alternating magnetic field, and then induces electric current on the winding of primary iron core, many
Individual primary iron-core coil, according to being necessarily linked in sequence, forms stabling current output.During wave size variation, secondary Oscillation Amplitude is also
Can change therewith.
The present invention under the sea situation of normal rips, cut-offfing by power electronic devices, only make the primary unit close to center
Work so that effectively winding length is shorter, can reduce copper wastage, under ensureing that generator efficiency is not under rips sea situation
Fall;When wave increases, cut-offfing by power electronic devices, the primary unit work of order secondary centre when static,
Increase the length of effective winding, increase electromagnetic damping, it is ensured that while electric efficiency, make motor not damage because of billow.Namely
By controlling the switching of each section of stator winding, it is achieved the change of motor rated power under different sea situations.
The invention have the benefit that the present invention can well adapt to an application absorbing direct-drive type wave energy electricity generation system, gram
Take the problem that generator efficiency that in conventional power generation systems, " low load with strong power " brings is on the low side, in the situation guaranteeing that motor is not damaged by
Under, keep the generating efficiency that under different sea situation, motor is higher.
