Offshore wind turbine state monitoring system and method based on wireless sensor network

Abstract

The invention discloses an offshore wind turbine state monitoring system based on a wireless sensor network. The offshore wind turbine state monitoring system comprises a plurality of state monitoring sensor nodes which are used for acquiring and processing information and transferring the information to cluster head sensor nodes, a plurality of the cluster head sensor nodes which are used for acquiring and processing the information transmitted by all the state monitoring sensor nodes in a cluster and transferring the information to a master control center and the master control center which is arranged at the bottom of a tower tube of a wind turbine, wherein the plurality of the state monitoring sensor nodes are respectively arranged on blades, a transmission system and the tower tube of the wind turbine; and the plurality of the cluster head sensor nodes are respectively arranged on a wheel hub, an engine room deck and the joints of all the sections of the tower tube of the wind turbine. The system has the advantages of convenience and quickness in layout, comprehensive monitoring, high-efficient communication and the like, and can facilitate fault early warning and service life prediction of the offshore wind turbine under the unattended situation, be conductive to providing a scientific basis for preventive maintenance of the wind turbine, reduce the fault incidence rate and further reduce the maintenance cost of the wind turbine.

Description

technical field [0001] The invention relates to a state monitoring system and method of an offshore wind turbine based on a wireless sensor network, which can realize real-time monitoring of the health status of key components of the offshore wind turbine. Background technique [0002] Due to the abundant offshore wind resources, it has many advantages such as large power generation, long power generation time, no noise restrictions, no land occupation, and large-scale development. At the same time, offshore wind power is generally close to the traditional power load center, which is convenient for local consumption and avoid Therefore, with the continuous advancement of wind power technology, vigorously developing offshore wind power has become a new trend in the development of the wind power industry. However, although offshore wind resources have more development potential than onshore ones, the environmental conditions are very harsh. Maintenance requires the use of spe...
