Description

                 This paper is a CAN-based architecture designed for the purpose of monitoring and fault diagnosis of wind turbines. CAN is a Message-based protocol designed specifically for Automotive, later Aerospace, Industrial automation, and Medical equipment. CAN interface module is used to communicate the monitored parameters between the wind turbine and the control center. During the transmission of the data from one node to another node, a disturbance occurs. To avoid these disturbances we propose the CAN protocol.


INTRODUCTION

In this project, we declare the system with ARM and CAN protocol to monitor and diagnose the problems in the wind turbine application. The project deals with the data transmission between two units at the exact time without any disturbance. The data transmission time is increased with the CAN protocol. ARM core1 runs with CAN and LPC2148 as wind turbine units to which sensors are connected and ARM core2 as Fault diagnosis and monitoring section. A discussion about weather condition (WC) monitoring and generation voltage (GV) display is also added to this design. The data acquisition node collects the sensor data through the CAN protocol. The basic view of this technique is to reduce the possibility of fault diagnosis and increase the monitoring of wind turbines.
