A Cooperative Decision Algorithm to Enhance the Wireless Link Connectivity of the Offshore Wind-Turbine Power System with Wireless Networks

Abstract

In general, the condition monitoring system (CMS) with wireless sensor network (WSN) and the wireless USB (WUSB) could be considered as a promising technique to manage the future offshore wind-turbine (WT) power system wirelessly for fully employment of wireless multimedia services. However, it still needs a highly reliable solution to tackle with the wireless link breakage problem caused by offshore capricious climate condition as well as by obstacle of wireless devices. Therefore, in this paper, we suggest a cooperative decision algorithm as to guarantee higher reliability of the supervisory control and data acquisition (SCADA) & CMS’s fault diagnosis monitoring operation of the offshore WT power system with WSN-WUSB network. We apply a cooperative decision algorithm for recovering the wireless link disconnection and providing a new link path, based on the proposed Orphan Notification message protocol. This algorithm can intelligently select the transmission path with the better channel conditions and thus, improve the reliability of the network. Simulation result shows that the proposed scheme effectively enhances the wireless link connectivity and the overall network performance.
