Abstract

An embodiment of the invention provides a method and a system for monitoring a fan and a wind turbine monitoring system, wherein the fan monitoring system comprises a fan monitor, a linkage module and a video monitor. The fan monitor is used for receiving an alarm signal sent by a fan controller installed on the fan and sending the alarm signal to the linage module, and the alarm signal comprises alarm time and a fan logo; the linkage module is used for analyzing the alarm time and the fan logo in the alarm signal and sending the analyzed alarm signal to the video monitor; and the video monitor is used for determining fan image information matched with the fan logo and the alarm time according to the fan logo and the alarm time and displaying the fan image information and can solve the problem of hysteresis of a wind turbine monitoring mode.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind turbine monitoring method and system, and a wind turbine monitoring system. Background technique [0002] With the development of the wind power industry, the safe and stable operation of wind turbines has attracted more and more attention. Due to the relatively remote geographical location and harsh conditions of wind farms, once a fault occurs, not only the maintenance cost is high, but also the power generation will be affected due to downtime, causing huge economic losses. Therefore, installing a monitoring system on wind turbines can help maintenance personnel to detect unit failures as early as possible and carry out maintenance in a planned way, thereby improving the utilization rate of the unit and extending the life of the unit. [0003] During the operation of the fan, once an overspeed phenomenon occurs, it will seriously affect the safety and rel...
