PIC Mictrocontroller
Abstract— Wind energy has emerged as one of the most important and economical renewable energy source. The generated electricity is from the air currents flowing across the earth's surface. Today, electricity generating wind turbines employ proven and approved technology, and provide a sheltered and reliable energy supply. Wind Turbines are located in remote areas mostly, where there are rigid environmental conditions. There is a great obligation to monitor the turbines to detect impending failures. This paper aims at monitoring the wind turbine parameters and intimation at the impending failure conditions. Wind turbine monitoring system collects the parameters such as Speed, Temperature, vibration, voltage and current from the essential

The data are periodically updated to the control center. Depending on the data that has been collected from the monitoring system, manipulations are done and the fault control system makes the decision of location and the type of fault that has occurred in the wind turbine. In case of any abnormal conditions, we can automatically shutdown the turbine for a period of time, till the parameters become normal. We use CAN Network to communicate between the Wind turbine and the control center . PIC Mictrocontroller is used for monitoring and control operations and it uses a master-slave configuration.The GSM Module is used to intimate the owner with an SMS when abnormal conditions occur and indicate the fault type.

Wind energy has undergone a remarkable expansion in modern times. As wind farms are aging, their operations and maintenance issues are gaining significance. The wind …show more content…
The LM35 does not require any apparent calibration to contribute suggestive accuracies of ±1⁄4˚C at room temperature and ±3⁄4˚C over a full −55 to +150˚C temperature range. Low cost is guaranteed by precision and calibration from the bottom level. The LM35’s low output impedance, linear output, and precise inherent calibration make interfacing to readout or control circuitry especially easy. It can be used with single power supplies, or with plus and minus supplies. As it stands off only 60 µA from its supply, it has very low self-heating, less than 0.1˚C in still air. The LM35 is graded to operate over a −55˚ to +150˚C temperature
