Description
Technical field
The utility model relates to a kind of wind speed measuring device, the wind speed measuring device when relating in particular to a kind of wind-powered electricity generation unit operation.
Background technology
The wind speed measuring device of wind power generating set employing at present mainly contains two kinds, and a kind of is at blower fan cabin afterbody anemoscope to be installed, and another kind is near upright anemometer tower wind power generating set.The mode that use is installed anemoscope at blower fan cabin afterbody under the static situation of blower fan, can accurately be measured the wind speed of blower fan position; When blower fan normally moved, because the influence of the turbulent flow that the wind wheel rotation produces, the wind velocity signal that anemoscope is measured can not correctly reflect the actual value of the wind speed of blower fan position.There is following defective near the measuring wind speed tower is built in use wind power generating set mode: the first, and it needs extra construction cost; The second, the wind speed of the position of measuring wind speed tower can not really replace the wind speed of wind power generating set position.
The utility model content
The purpose of this utility model is to overcome the above-mentioned defective that prior art exists, when a kind of wind-powered electricity generation unit operation is provided, can accurately measure blower fan position wind speed wind speed measuring device.
The technical solution of the utility model is: it comprises the wind wheel of responding to wind speed, the blade angle sensor that is used to measure the wind wheel blade angle is installed in the rotating shaft of the servomotor in the wind wheel wheel hub, controller in the output terminal of blade angle sensor and the wind wheel wheel hub is connected, on the slip ring in the wind wheel wheel hub wind speed round sensor is installed, the output terminal of wind speed round sensor is connected with generator, the inverter of being located in the tower tube is connected with generator by cable, inverter gets access to grid, and the wind speed round sensor is connected with controller with inverter.
During fan operation, the tach signal that the wind speed round sensor produces, the power signal that blade angle signal that the blade angle scrambler produces and inverter produce is by wired or radio to controller, and controller goes out the actual wind speed of blower fan position according to these calculated signals.
The utility model utilizes the member of blower fan own and disposes suitable accessory and realize that the wind speed of blower fan position detects, avoid rotating the air speed error that the influence of air-flow is caused by wind wheel, measurement data is accurate, help improving generating efficiency, reduce blower fan load, for the optimal control of fan operation provides the basis.
Description of drawings
Fig. 1 is the utility model embodiment wind speed measuring device synoptic diagram.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to Fig. 1, present embodiment comprises the wind wheel 1 of responding to wind speed, the blade angle sensor 2 that is used to measure the wind wheel blade angle is installed in the rotating shaft of the servomotor in wind wheel 1 wheel hub, controller 7 in the output terminal of blade angle sensor 2 and wind wheel 1 wheel hub is connected, on the slip ring 3 in wind wheel 1 wheel hub wind speed round sensor 4 is installed, the output terminal of wind speed round sensor 4 is connected with generator 5, the inverter of being located in the tower tube 6 is connected with generator 5 by cable, inverter 6 gets access to grid 8, and wind speed round sensor 4 is connected with controller 7 with inverter 6.
During fan operation, wind wheel 1 rotates, wind wheel 1 drives wind speed round sensor 4 by slip ring 3 and rotates, wind speed round sensor 4 produces the required synchronous speed signal of measuring wind speed, pass to controller 7, the rotation of wind wheel 1 simultaneously drives generator 5 and rotates, the electric power that generator 5 produces sends electrical network to by inverter 6, the power signal that is used for measuring wind speed that inverter 6 will measure sends controller 7 to, blade angle sensor 2 sends the needed blade angle signal of measuring wind speed to controller 7, controller 7 is according to the tach signal that collects, power signal and blade angle signal just can calculate the wind speed size of blower fan position.
Below just specifically describe an embodiment of the present embodiment, a preferred demonstration example.The present embodiment protection domain has more than and is limited to described embodiment.All and technical scheme present embodiment equivalence all belongs to protection domain of the present utility model.
