Description
Technical field
The utility model relates to a kind of power of fan prediction unit of power industry.
Background technology
Wind is the new forms of energy that a kind of potentiality are very large, 18 beginnings of the century, sweep away the once violent strong wind of two countries of Great Britain and France, wipe 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 strain.The only opinion with regard to pulling out tree, wind has just sent 10,000,000 horsepowers (7,500,000 kilowatts within the several seconds; One horsepower equals 0.75 kilowatt) power have people to estimate, on the earth, can be used to generating wind resource approximately have 10,000,000,000 kilowatts, be almost 10 times of present whole world hydropower amount.The energy that at present the annual coal combustion in the whole world obtains, 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, then 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 air vane rotation, then sees through booster engine by the speed lifting of rotation, impels generator generating.According to current windmill technology, be approximately the gentle breeze speed (degree of gentle breeze) of three meters per second, just can start 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 the country such as Finland, Denmark; China also advocates energetically in west area.Miniature wind power generation system efficiency is very high, but it is not to be only made up of a generating head, but one has the mini system of certain scientific and technological content: 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 can make head rotate neatly to realize the function of empennage adjustment direction; The rotor of head is permanent magnet, and stator winding cutting magnetic line produces electric energy.
The wind resource of China is very abundant, and the mean wind speeds in most areas are all per second more than 3 meters, particularly northeast, northwest, southwest plateau and offshore islands, and mean wind speed is larger; Some places, 1 year more than 1/3rd time was all strong wind sky.In these areas, existing many successful medium and small wind power generation plants are in running now, and development wind-power electricity generation is up-and-coming.
The defect of wind-power electricity generation maximum is unstable, wind-power electricity generation itself has undulatory property, intermittence, low energy densities, the feature such as uncontrollable, thereby wind power be also fluctuation, intermittently, system must consider to leave enough standby power supplies and peak in the time of operation, can be normally to customer power supply during with guarantee wind-powered electricity generation undercapacity, this has just increased the difficulty to electrical network planning and scheduling.Wind power prediction becomes ingredient indispensable in electric system, but very fast owing to changing throughout the year, makes Various Seasonal, different weather phenomenon make Exact Forecast wind field wind regime become comparatively difficulty.But the size of wind-force meets certain meteorology, weather, Seasonal Regularity, by wind energy turbine set generated energy being carried out to the Accurate Prediction in short-term and mid-term, can significantly reduce electrical network spinning reserve capacity, thereby effectively reduce wind generator system cost, and dispatch reliable foundation is provided for operation of power networks.
Based on needing above, the special the utility model that proposes.
Utility model content
The utility model provides a kind of power of fan prediction unit, to realize the effective prediction to wind-powered electricity generation unit wind-power electricity generation.
The technical solution of the utility model is: a kind of power of fan prediction unit, comprise the meteorological data collection device at least being formed by wind transducer, wind sensor, described meteorological data collection device is connected with power conversion device, and described power conversion device is connected with output unit.
Further, described power conversion device by the power conversion device in spring of connection parallel with one another, summer power conversion device, autumn power conversion device and winter power conversion device form.
Further, spring, power conversion device was connected with the first gauge tap; Summer, power conversion device was connected with the second gauge tap; Autumn power conversion device connect with the 3rd gauge tap and winter power conversion device connect with the 4th gauge tap.
Further, meteorological data collection device also comprises humidity sensor and/or temperature sensor.
Further, described wind transducer, wind sensor, humidity sensor and temperature sensor are connected with power conversion device through optical-fibre channel respectively.
Further, described output unit is made up of display screen.
Further, described power conversion device is connected with power supply.
Further, described power conversion device is connected with storer.
The beneficial effects of the utility model are: adopt the utility model just can utilize the meteorological data collection device being at least made up of wind transducer and wind sensor to gather the weather information at wind energy turbine set place, the weather information prediction that utilization collects draws the generator power of wind turbine, realize the effective prediction to wind-power electricity generation, and then can be according to the formulation generation schedule that predicts the outcome, reduce electrical network spinning reserve capacity, for operation of power networks scheduling provides reliable foundation.More particularly, by spring in parallel, summer, autumn, winter power conversion device is set, realize Various Seasonal application different capacity conversion equipment prediction generating efficiency, to improve the object of accuracy of forecast.The utility model is simple in structure, effect is remarkable, is suitable for promoting the use of.
