Question

Positioning of wind turbine depending on wind speed using microcontroller

Answer 1

In this study, a microcontroller based data logger for measuring wind speed andwind direction has been designed. The designed system uses the Atmelmicrocontroller family which consists of sensor inputs, a microcontroller and adata storage device. The system was designed and developed to measure the windspeed and direction with the help of anemometer and wind vane sensorsrespectively. The results were stored in an Electrically Erasable ProgrammableRead Only Memory (EEPROM) for post process analysis. The collected data weretransmitted to a PC through an RS-232 serial interface, and were processed usingthe 208W Data logger support software. Wind speed and direction measured bythe microcontroller-based data logging system were analyzed using line graphs,scatter correlation charts and wind roses. Wind speeds were measured at 9.00a.m, 12.00 noon and 5.00 p.m using fabricated sensors and also at JKUATmeteorological station. The correlation indices of microcontroller–based datalogger instrumentation system data and JKUAT meteorological data weredetermined. The correlation indices for the corresponding three times werecalculated as 0.997, 0,997 and 0.999 respectively. Thus the wind speed measuredby the fabricated sensor was found to correlate strongly to the to the JKUATMeteorological datasheet. Wind rose analysis revealed that the wind direction wasfairly consistent from between 180

Answer 2

Answer:

rughly 35.5 degrees

This translates in a maximum conversion of 38.5% of the wind force into rotational motion. Therefore, the blades should be tilted at an angle of roughly 35.5 degrees from the oncoming air stream to obtain the optimal amount of energy using flat blade windmills.
