SAFETY SYSTEM OF WIND-POWERED GENERATORS AND DEVICES WITH PROPELLER BLADES Russian patent published in 2012 - IPC F03D7/04 

FIELD: power engineering.

SUBSTANCE: system comprises a group of sensors and a control unit. The group of sensors is made in the form of groups of receivers and transmitters forming a multilinked system to register deviation of spatial position of structure elements from a normal one and installed at elements of the wind powered generator structure. The control unit is made in the form of serially connected processing unit and analysis unit, at the same time the outputs of a group of receivers are connected to the first group of information inputs of the processing unit, the output of which via a wind powered generator computer is connected to organs of control and/or indication, and the second group of information inputs of the analysis unit is connected to the appropriate group of wind powered generator computer outputs. Groups of transmitters and receivers may be arranged on the first and second coaxial propellers of the wind powered generator. The processing unit may be arranged in the form of a group of serially connected amplitude detectors and analog to digital converters.

EFFECT: higher efficiency of the safety system by increasing its sensitivity, information value and expansion of functional capabilities.
