A CAN Bus Based System for Monitoring and Fault Diagnosis in Wind Turbine

A CAN based architecture is designed for the purpose of intensive monitoring and fault diagnosis in wind turbine. It provides a full automation system. CAN (Controller Area Network) Bus is a high speed serial data bus with high transmission rate. CAN Bus interface technique with an integration of electro-mechanical subsystems that embeds network control systems is proposed along with ARM controller to monitor and diagnose the problems in the wind turbine application. CAN BUS will enable the data transmission between two units at the same time without any disturbances. The data transmission time is increased with this CAN protocol. ARM core1 runs with CAN and LPC2148 as wind turbine unit to which sensors are connected and ARM core2 as Fault diagnose and monitoring section. A discussion about weather condition (WC) monitoring and generation voltage (GV) display is also added in this design. Data acquisition node collects the sensor data through CAN protocol. This technique reduces the possibility of fault and increase the monitoring of wind turbine.
