Description
Technical field
The utility model relates to weather environment monitoring field and wind power generation field, is specifically related to a kind of wind speed and direction calibration system.
Background technology
Wind is the very large new forms of energy of a kind of potentiality, 18 beginnings of the century, sweep away the once violent strong wind of Great Britain and France two countries, wiped out 400 wind-force mills, 800 houses, 100 churches, more than 400 sailing boat, and having thousands to come to harm, large tree is uprooped in 250,000 strains.Only set and opinion with regard to pulling out, wind has just sent 10,000,000 horsepowers (namely 7,500,000 kilowatts within the several seconds; One horsepower equals 0.75 kilowatt) power have the people to estimate, the wind resource that can be used to generate electricity on the earth approximately has 10,000,000,000 kilowatts, almost is 10 times of present whole world hydropower amount.The present energy that obtains of the annual coal combustion in the whole world, only have wind-force in 1 year the energy that provides 1/3rd.Therefore, all take much count of both at home and abroad utilizing wind-force to generate electricity, tap a new source of energy.
The kinetic energy of keeping watch is transformed into mechanical kinetic energy, again mechanical energy is converted into electric power kinetic energy, Here it is wind-power electricity generation.The principle of wind-power electricity generation is to utilize wind-force to drive the air vane rotation, sees through booster engine with the speed lifting of rotation again, impels the generator generating.According to present windmill technology, approximately be the gentle breeze speed (degree of gentle breeze) of three meters of per seconds, just can begin generating.Wind-power electricity generation forms one upsurge just in the world, because wind-power electricity generation does not need to use fuel, also can not produce radiation or air pollution.
Wind-power electricity generation is very popular in countries such as Finland, Denmark; China also advocates energetically in the west area.Miniature wind power generation system efficient is very high, but it is not only to be comprised of a generating head, but the mini system that certain scientific and technological content is arranged: aerogenerator+charger+digital inverter.Aerogenerator by head, turn, empennage, blade form.Every part is all very important, and functions is: blade is used for accepting wind-force and transfers electric energy to by head; Thereby empennage makes blade obtain maximum wind energy facing to the direction of the wind comes from all the time; Turn and to make head rotate neatly to realize the function of empennage adjustment direction; The rotor of head is permanent magnet, and the stator winding cutting magnetic line produces electric energy.
In general, force 3 wind just has the value of utilization.But from the angle of economical rationality, wind speed just is suitable for generating greater than 4 meters of per seconds.According to surveying and determination, one 55 kilowatts wind power generating set, when wind speed was 9.5 meters of per seconds, the output power of unit was 55 kilowatts; When 8 meters of wind speed per seconds, power is 38 kilowatts; During 6 meters of wind speed per seconds, only have 16 kilowatts; And during 5 meters of wind speed per seconds, only be 9.5 kilowatts.As seen wind-force is larger, and economic benefit is also larger.
In China, the medium and small wind power generation plant of existing many successes is in running now.
The wind resource of China is very abundant, and the mean wind speeds in most areas are all at per second more than 3 meters, particularly northeast, northwest, southwest plateau and offshore islands, and mean wind speed is larger; Some places, the 1 year time more than 1/3rd all was the strong wind sky.In these areas, the development wind-power electricity generation is up-and-coming.
Therefore, at the scene of wind-power electricity generation, generally all arrange a kind of can measuring wind and aerovane, measure wind power plant's wind speed and direction on the same day, the coefficients such as the output electric energy of rough calculation generating plant.In the weather environment observation process, a plurality of places also can arrange the surveying instrument of wind speed and direction,
The wind gage aerovane plays vital effect for wind power generating set.Show as the most intuitively 2 points: 1) if aerovane breaks down or during measured deviation, the running that directly has influence on wind power generating set and the situation of exerting oneself (make wind power generating set head inaccurate to wind).2) wind gage breaks down or during measured deviation, easily reports wind power generating set power and wind speed not to be inconsistent fault; Simultaneously inaccurate if there is surveying wind, for the startup of wind power generating set, excision all can be influential.
Use relatively large mechanical type wind speed, aerovane in the wind power generating set that my company uses at present.And there are wear phenomenon in mechanical type wind speed, aerovane in the process of using, and according to Application standard, should carry out regular demarcation to equipment in the process of using.But because this work is not carried out in the restriction of the conditions such as scene, only breaking down at wind speed, aerovane directly more changes jobs when damaging.
In view of the importance of wind speed, aerovane and my the company characteristics of wind power generating set maintenance work at the scene, carry out designing and developing of wind speed, aerovane calibration record instrument.By the use of on-the-spot wind speed, aerovane calibration record instrument, in the wind energy turbine set line service, add the testing of wind speed, aerovane.Further improve wind power generating set operational efficiency and wind energy turbine set generating capacity.
In long use procedure, this wind instrument can break down unavoidably, inaccurate phenomenon appears measuring, but be difficult to determine from the data of measuring instrument itself whether this surveying instrument inaccurate phenomenon occurs measuring, the calibration system that so just needs a kind of wind speed and direction measuring instrument, data on the on-the-spot wind instrument are calibrated, in time change out of order wind instrument.
