Description

A kind of wind energy conversion system kuppe
Technical field
The present invention relates to wind turbine technology field, specially a kind of wind energy conversion system kuppe.
Background technology
Currently, wind energy conversion system needs external wind speed and direction information adjustment unit execution action to pursue maximum generating watt and machine Group protection.Therefore, it is necessary to accurately measure the parameters such as wind speed and direction to ensure unit safety operation and generated energy.
Existing unit is mainly upwind unit, and both wind wheel was located at cabin upwind.Existing wind measuring device is commonly installed In engine room cover, that is, it is under wind wheel at wind direction.Since wind is after wind wheel, energy is partially converted into the machinery of wind wheel rotation Can, and since the presence of blade causes survey wind different from wind speed and direction at practical wind wheel, this will influence unit allocation and judge, from And influence generated energy.
Existing anemobiagraph generally use is horizontally disposed, can only measure the variation of horizontal plane upwind, actual set is intricately There are the variation of vertical plane upwind under shape, need to measure whether wind-force in vertical direction, avoid underestimating wind load.
Invention content
The present invention is intended to provide a kind of kuppe of wind energy conversion system, can accurately measure wind speed and direction, and can also provide it The measurement of its environmental parameter.
Technical solution according to the invention, the wind energy conversion system kuppe, including kuppe, the kuppe is interior to be equipped with control Device, dynamic pressure manometer, static pressure manometer, wind wheel azimuth instrument and thermometer, controller connect power supply and output signal, and dynamic pressure is surveyed Pressure meter, static pressure manometer, wind wheel azimuth instrument and thermometer are separately connected controller;The front end of kuppe is protruded, and part is protruded Surface be provided with multiple holes, anemometer connector is installed, anemometer connector passes through pipeline and connects dynamic pressure manometer, multiple surveys in hole Bearing connector, pipeline and dynamic pressure manometer form anemobiagraph array;Be additionally provided with hygrometer in the kuppe, the hygrometer with Controller is connected;Wind wheel azimuth instrument obtains wind wheel azimuth letter using obliquity sensor, encoder or close to switch Number.
Further, the hole be set to the kuppe protrusion center of part and being arranged circumferentially along center.
Further, the hole circumferentially is externally provided with multiple holes.
Further, the hole has different opening directions.
The beneficial effects of the present invention are:Wind speed and direction can accurately be measured;By multiple sensor data analysis, realize Prediction to ice condition;Built-in controller realizes unified power supply, data output.

Specific implementation mode
With reference to specific embodiments and the drawings, the invention will be further described.
As shown, wind energy conversion system kuppe of the present invention, includes the kuppe 1 outside wind turbine hub.In kuppe 1 Interior to be equipped with controller 4, dynamic pressure manometer 5, static pressure manometer 6, wind wheel azimuth instrument 7 and thermometer 8, controller 4 connects power supply And output signal, dynamic pressure manometer 5, static pressure manometer 6, wind wheel azimuth instrument 7 and thermometer 8 are separately connected controller 4.Control Microcontroller, the electric signal of direct receiving sensor output may be used in device 4.The front end of kuppe 1 is protruded, and the surface of part is protruded Different location is provided with multiple holes, and anemometer connector 2 is equipped in hole, and anemometer connector 2 connects dynamic pressure manometer 5 by pipeline 3, Multiple anemometer connectors 2, pipeline 3 and dynamic pressure manometer 5 form anemobiagraph array.Hole has different opening directions, when a certain When wind speed and direction incoming blows to kuppe, the dynamic pressure manometer corresponding to different location hole measures Different Results, according to each measuring point Dynamic pressure and static pressure can calculate measuring point wind speed, wind direction can be solved by each measuring point wind speed.To improve the accuracy measured, The center of part is protruded in kuppe 1 and the circumferential direction along center is gathered hole, and different location can be with outside circumferentially disposed hole Equipped with multiple holes, the wind direction obtained is the vector of three dimensions, i.e., also includes not only on vertical plane comprising direction on horizontal plane Wind direction.Static pressure manometer 6 can be mounted on according to interior spatial structure in wheel hub, and dynamic pressure manometer 5 and static pressure manometer 6 combine Also have the function of measuring atmospheric pressure.
Hygrometer 9 is also provided in kuppe 1, for obtaining humidity parameter, hygrometer 9 equally with 4 phase of controller Unified power supply, data output are realized in connection.Wind wheel azimuth instrument 7 may be mounted in wheel hub, and measuring center and wind wheel are rotated It is axially coincident.Obliquity sensor, encoder or the close switch that wind wheel azimuth instrument 7 utilizes obtain wind wheel real-time azimuthal angle, lead to It crosses and obtains wind speed round with the azimuthal angle calculation of time change.Since wind wheel rotates, surveyed wind speed and direction is opposite wind wheel, because This measures wind wheel azimuth and rotating speed by wind wheel azimuth instrument, to obtain the wind speed and direction of opposite cabin.
The present invention calculates atmospheric density by thermometer and static pressure manometer measured value;According to the sound pressure difference and sky measured Air tightness calculates wind speed at measuring point;According to wind speed at measuring point and each point position and kuppe shape, opposite wind is calculated The wind direction of wheel;Wind wheel azimuth and wind speed round are obtained according to wind wheel azimuth instrument, the wind speed and direction of opposite wind wheel is converted into The opposite wind speed of cabin and the wind direction of three-dimensional, detection are comprehensively accurate.
