Offshore wind power is safe and reliable,and resources are abundant.However,wind farms are generally distributed in harsh environment,and difficult to reach and frequent failures.Therefore,effective and reliable monitoring is the key to ensure normal operation of wind power generation system.In order to solve the difficult wiring and high cost of wired communication in offshore wind turbine condition monitoring system,we need to study wireless sensor network networking technology.This paper studies the monitoring process,monitoring parameters,wireless communication technology and corresponding wireless sensor network technology of offshore wind turbine state monitoring system,and improves it to ensure the normal operation of wind power system.First of all the energy constrained nodes of traditional routing protocols for this problem in the routing protocol,we proposed RPL load balancing routing algorithm based on improved residual level,improve the load balancing mechanism in the routing process,considering the two factors of node distance and energy,reduce the energy consumption and prolong the objective of network life cycle.Aiming at the problem of node of the current offshore wind turbine condition monitoring system in the deployment,study the existing node deployment scheme,so that the node coverage optimal performance for the purpose of introducing a particle swarm algorithm based on node deployment method,through the idea of particle swarm optimization algorithm,the design and implementation of node coverage performance optimal deployment scheme.At the same time,the improved algorithm in this paper,the design of the corresponding scene,using MATLAB simulation platform,respectively on the average energy consumption of nodes,the number of death nodes and node coverage simulation,verified the feasibility of RPL routing algorithm and particle swarm algorithm is applied to the offshore wind turbine monitoring system.This paper establishes a theoretical foundation for the design of wireless networking technology in offshore wind turbine condition monitoring system,and provides an important reference for better application of wireless sensor networking technology in condition monitoring system in the future.
