Background technique
Wind energy power is a kind of technology and a device with fastest developing speed in the new and renewable sources of energy field; Annual growth reaches 35%, is the best countries of Wind Power Utilization such as Germany, Denmark, three countries of Spain, Germany; Wind-power electricity generation accounts for 3% of total electric weight, and Denmark surpasses 10% of total electric weight.Whole world wind-power electricity generation accumulative total in the end of the year 2007 will reach 8,300 ten thousand kilowatts, and wherein 5,800 ten thousand kilowatts in Europe.3,200,000,000 kilowatts of China's wind energy contents, 2.5 hundred million kilowatts of can develop electric motor power, whole nation accumulative total is installed 200,000 of small-sized wind power generators, accounts for 0.11% of national electric power electric motor power, and compares a certain distance in addition abroad.But wind-power electricity generation year increases all about 50%.At present the storage means of big capacity electric energy is to build the pump up water method storage of electrical energy in power station of secondary.
Consult Fig. 1; Big-and-middle-sized wind power generation method in various countries and electricity generating device are at present; Obtain the kinetic energy of natural wind with wind wheel; Be transformed into the mechanical energy that wind wheel rotates; Through speedup box (because generator requires rotating speed higher; Wind speed round is lower) drive generator, need processing such as rectification, the inversion user that just can be incorporated into the power networks under the situation that the electric energy that obtains from generator has, the composition of generator set is as shown in Figure 1.
This generator set is in order to ensure the demand of generator for electricity generation; At first be to guarantee the wind wheel smooth running through mechanisms such as fixed pitch stall-adjusted and the adjustings of feather angle on the wind wheel; If the wind wheel rotating shaft is a horizontal positioned; For guaranteeing that wind wheel always is in state down with the wind; Also has a wind plant; What have uses tail vane, and what have takes turns with the cabin.The applied generator of wind-power electricity generation can be an asynchronous induction generator; Software grid-connecting apparatus through thyristor control networks; Also have with coil wound rotor induction generator, double fed induction generators, synchronous generator or the like, these all are to be the generator of wind generator set design manufacturing specially.Because the rotary speed unstabilization of this transmission system is fixed, also to be equipped with frequency converter.Be the generator variable speed, the constant frequency The Application of Technology.For the runnability of the wind-driven generator of present operation and follow the tracks of the practical operation situation of the 1500KW wind-driven generator that Datang genco (Jilin Province) buys German Endy Co., Ltd and Zhuo Lun company co-production and the data of consulting relevant wind-power electricity generation, find that there is the problem of the following aspects in present wind-power electricity generation:
1. can not make full use of wind energy.The characteristics of natural wind are that wind speed, wind direction change at random cause very big difficulty to wind-power electricity generation; It can bring impact to transmission system; Wind wheel also will be followed wind direction and changed and change; Fixed and the huge impact of the rotary speed unstabilization that brings for fear of the rapid change of wind energy is so have to way such as utilizable wind energy employing feather and fixed pitch is run off.Especially this variable propeller pitch device need change the angle of wind wheel blade over against wind direction under the situation that wind wheel rotates; The complex structure rate of fault is very high, because it is in wheel hub, and the root of blade; Rotary bearing must be special the manufacturing, and with other wind-driven generators can not be general.For the fixed pitch wind wheel is to be utilized in wind energy big the time, and the wind wheel blade shape makes it wind energy and runs off and reduce thrust, increases rotational resistance and reaches the steadily purpose of rotation of wind wheel.This in a word method can not all be transformed into mechanical energy pouncing on the wind energy that obtains in the natural wind energy to greatest extent.
2. the changeable energy with sudden change of natural wind is delivered to the very big step-up gear of inertial force, generator; They can not absorb the impact energy of frequent appearance; So must destroy the component of this system; Such as more than the 30 typhoon power generator of Datang genco in Jilin Province's from Germany's purchase; Operation was that gear-box damages less than 3 years all, reached the degree that can not repair.
3. this wind-power electricity generation must have regulator control system, and comprising wind speed round, electric energy frequency adjustment and regulator control system could guarantee power generating quality like this, and the regulation and control of these two parts not only complicacy but also reliability are relatively poor.
4. the electric energy of wind-power electricity generation can not store, as long as send electric energy, just is incorporated into the power networks and supplies with the user, and especially in low power consumption, the electric energy that sends runs off in vain.Very uneconomical.This also is the common common problems that exist in present all power station in the world.
5. it must be special-purpose that this generator set manufactures and designs; Because the parts that he adopted are not universal components; And the tall and big heaviness of equipment; So cost of material, technology cost, transportation, installation, maintenance, etc. user cost all very high; All must be special-purpose from wind wheel, speedup box to generator, even the product of different manufacturers all can not exchange with a kind of model power.
6. utilize to build the pump up water method in power station of secondary and store jumbo electric energy and exist the construction period long, the condition harshness needs the high mountain of water and water, expense ten minutes costliness.
Existing in a word wind power generating set exists two large problems: one is the rotating speed problem, and many effort of doing for the problem that overcomes it sacrifice that costs a lot of money was not only carried cost, and wind energy also will run off; Another problem be exactly the transmission system of generator set be a rigid system, can not absorb natural wind impact jumpy and system vibration, operation brings potential safety hazard to system, is the main root that accident takes place frequently.
