Abstract

The invention relates to a condition monitoring device for a slidably yaw system of a wind generator. The condition monitoring device comprises a data collecting device used for acquiring signals of a yaw mechanism; a data collecting card used for receiving the signals monitored by the data collecting device; an upper computer used for receiving and processing the signals transmitted by the data collecting card; a transmitting module used for transmitting the data processed by the upper computer; a computer used for receiving the data transmitted by the transmitting module and storing and analyzing the data through a software. According to the arrangement, changes of relative parameters are monitored during yaw, drive torque of a yaw motor is calculated, work state of the yaw system of a wind turbine is timely judged, safe running of the wind turbine is guaranteed, location of a fault of the yaw system is accurately judged, and maintenance of the wind turbine is supported.

Description

technical field [0001] The invention relates to a state monitoring device for a sliding yaw system of a wind power generator. Background technique [0002] The sliding yaw system of a wind turbine generally consists of three parts: a yaw control system, a yaw mechanism, and a twisted cable protection device. The yaw mechanism is composed of a yaw motor, a yaw reducer, a yaw gear, and a yaw claw. [0003] The yaw control system compares the measured wind direction and wind speed signals with the direction of the nacelle. If the conditions for yaw movement are met, a yaw command is issued, and the yaw motor starts to start yaw. During the yaw process, the yaw mechanism generally maintains a constant yaw speed. In the yaw mechanism, the large yaw gear is fixed on the tower, and the yaw reducer is fixedly installed on the base of the nacelle. The yaw motor drives the yaw pinion to rotate through the yaw reducer, and the yaw pinion meshes with the yaw large gear to push the na...
