Design of Wireless Sensor Network in SCADA System for Wind Power Plant

Wireless Sensor Networks (WSNs) is a novel technology, which is developed with the advancement of micro-electronic, computing, and wireless communication technology. WSNs has merits of distributed information processing, covering broadly, and remote monitoring and control. Considering the disperse deployment, wind power resource random and seasonal characteristic in wind plant, we apply WSNs to SCADA system for wind power plant in this paper, which conquers the lack of disperse distribution, difficulty of remote monitoring in wind plant. Considering node cost, resource demand and communication reliability, the hardware of sensor node and sink node are based on 80C51 and ARM chips respectively, and mu C/OS-II is selected as the ARM chip operating system. IDD-PC is adopted as routing scheme in wireless data transmission among nodes, which can balance node energy consumption, and be propitious to stability of the network structure. As to the energy limitation of WSN, the method of automatic compensating energy by wind generator is provided.
