Abstract
The invention discloses an automatic wind-searching and over-wind-speed protecting control method for a wind driven generator. A PLC (Programmable Logic Controller) is used as a central control part and a wind indicator and an angle transducer are utilized to cooperate so as to realize the automatic wind-searching. A wind speed transducer is utilized to realize the functions of wind speed monitoring and over-wind-speed protection. According to the method provided by the invention, the wind driven generator can automatically search wind and the wind driven generator can be protected when the wind speed is ultrahigh, so that the stability and safety for electric energy output of the wind driven generator are increased.
Description
Technical field
The present invention relates to the wind powered generator control method field, be specially a kind of wind-driven generator automatic seeking wind and unnatural wind speed protection controlling method.
Background technique
Wind-driven generator is a kind of device that utilizes wind energy to generate electricity, and it is by installing rotating solid of rotation for head, be installed in blade on the head, be installed in empennage on the blade etc. and consist of, and the central shaft of blade is in transmission connection with head inside generator amature.During work, the effect of blade wind-engaging power is rotated, thereby realizes generator work generating.In the prior art, when change of the wind, generally be the direction of coming passive adjustment blade by being installed in empennage on the blade, this mode can't make the blade active accommodation to towards the direction over against wind-force, causes the unsettled problem of electric energy of wind-driven generator output.The too fast problem that causes the wind-driven generator inner member to damage of wind speed appears in simultaneously wind-driven generator work often, affects the safe operation of wind-driven generator.
Summary of the invention
The purpose of this invention is to provide a kind of wind-driven generator automatic seeking wind and unnatural wind speed protection controlling method, can't initiatively seek wind, the too fast problem that affects the wind-driven generator trouble free service of wind speed to solve the prior art wind-driven generator.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of wind-driven generator automatic seeking wind and unnatural wind speed protection controlling method, described wind-driven generator comprises head, be installed in the generator in the head, be rotatably installed in the blade of head one end, the solid of rotation of head motion is installed and is driven for head, the orientation adjusting motor of control solid of rotation motion, its Leaf central rotating shaft and generator amature are in transmission connection, it is characterized in that: on the described solid of rotation wind vane is installed, angle transducer, at wind-driven generator air velocity transducer is set, described wind vane, angle transducer, the signal output part of air velocity transducer, the control end of orientation adjusting motor accesses respectively a PLC, when described wind vane detects the wind direction angle and is A, wind vane is sent to PLC with the signal that detects, control orientation adjusting motor work when PLC receives the signal of wind vane, by orientation adjusting motor solid of rotation is rotated, simultaneously angle transducer detects that solid of rotation rotates and to the PLC transmitted, if angle transducer is T to the umber of pulse that PLC sends, when PLC detects the umber of pulse T=(A ÷ 5.9 that angle transducer sends to PLC) * 4 the time, PLC sends halt instruction to orientation adjusting motor, this moment, orientation adjusting motor quit work, solid of rotation rotates corresponding angle under orientation adjusting motor drives, finish the automatic seeking wind of head upper blade;
Default wind speed early warning value in the described air velocity transducer, when air velocity transducer detects outside wind speed more than or equal to default wind speed early warning value, air velocity transducer sends the unnatural wind speed signal to PLC, the backward orientation adjusting motor of unnatural wind speed signal that PLC receives air velocity transducer sends instruction, and the control orientation adjusting motor drives the solid of rotation lateral deviation to making the out-of-work angle of generator; Stop to send the wind speed early warning signal to PLC when PLC detects air velocity transducer, PLC control orientation adjusting motor drives the solid of rotation return, and generator is resumed operation.
The present invention uses PLC as central control unit; make solid of rotation drive head by wind vane, angle transducer cooperation and realize automatic seeking wind function; utilize simultaneously air velocity transducer to detect outside wind speed information; and by the motion of PLC control orientation adjusting motor drive solid of rotation, thereby realize stopping the function that the unnatural wind speed protection is carried out in generator work.
But the present invention makes wind-driven generator automatic seeking wind, and protects wind-driven generator when wind speed is too fast, has improved wind-driven generator electric energy output stability and Security.
