Problems solved by technology

If the vibration status monitoring system of wind turbines is directly incorporated into the optical fiber ring network, part of the large-capacity data in the real-time monitoring process will easily lead to link congestion, which will cause great harm to the remote monitoring of wind turbines
If the optical fiber ring network is re-laid, the construction will be difficult, the cycle will be long, and the cost will be high

Abstract

The invention provides a monitoring system for the vibration states of wind turbine generators based on a wireless network and relates to the technical field of vibration monitoring of the wind turbine generators. The system comprises data acquiring units, a wireless transmission unit, a data processing and fault diagnosing unit and a remote fault diagnosis unit, wherein the data acquisition unitof each wind turbine generator is used for acquiring and processing a vibration signal on a transmission chain of the wind turbine generator; data communication is performed between the wireless transmission unit and the data processing and fault diagnosing unit; a wireless transmission network adopts a mode of combining a backbone network with a sub-network; the data processing and fault diagnosing unit is used for comprehensively analyzing and diagnosing real-time data and historical data of each wind turbine generator according a control strategy preset by the system; the remote fault diagnosis unit is used for realizing remote fault diagnosis. The monitoring system disclosed by the invention has the advantages that network congestion of the wind turbine generators which are putted intooperation and have no monitoring of the vibration states can be effectively avoided, the state monitoring efficiency of the wind turbine generators is improved, monitoring intensity is reduced and accidents and damage are avoided.

Description

technical field [0001] The invention relates to the technical field of wind turbine vibration monitoring, in particular to a wireless network-based vibration state monitoring system for wind turbines. Background technique [0002] The blades, gearboxes and other transmission components of wind turbines operate in extreme natural environments such as high temperature, severe cold, salt spray, and plateau all year round, and the nacelle is located at high altitude, making maintenance inconvenient. If the wind turbine condition monitoring and fault diagnosis technology is used, not only can the downtime be changed into a planned downtime, but the reduction of the downtime will avoid the expansion of the accident, so that the enterprise's maintenance management of equipment can gradually transition from faulty maintenance and planned maintenance to condition monitoring. preventive maintenance. Guarantee the safe and reliable operation of wind turbines, improve the modernization...
