Lazer tabanlı sensörler kullanılarak rüzgâr hızı ve yönü ölçüm cihazı tasarımı

Rüzgâr hızı ve yönü ölçümlerinde çeşitli anemometreler ve yön belirleme cihazları kullanılmaktadır. Rüzgâr enerjisinden elektrik üretimi ve tahminleri için uygun maliyetli, hassas ölçüm aletlerine ihtiyaç duyulmaktadır. Bu çalışmada, lazer mesafe sensörleri, mikrodenetleyiciler ve bütünleşmiş elektronik devreler kullanarak bir anemometre tasarlanmıştır. Tasarım, ölçüm merkezinden sapan mesafeye göre rüzgâr hızı ve yönü ölçmektedir. Bu mesafe sayısal olarak hesaplanarak rüzgâr verileri elde edilmiştir. Mevcut tekniklerden farklı olarak tasarlanan bu yöntem, gerçek bir anemometre ile karşılaştırılmış ve hata analizi yapılmıştır. Hata analizi sonucu bağıl hata değeri 0.01685 olarak bulunmuştur. Bu çalışmada kullanılan yöntem, düşük maliyetli ve hassas bir anemometre tasarlama açısından önemli sonuçlar vermektedir.

Design of wind speed and direction measurement device using laser-based sensors

Different types of anemometers and direction determining devices are used in measuring wind speed and direction. Especially, low-cost and accurate measuring devices are required for the production and estimates of electricity generated from wind energy. Therefore, a design for an anemometer has been carried out using appropriate low-cost laser distance sensors, microcontrollers, and integrated electronic circuit equipment. The resulting anemometer from the design works based on the distance from the measurement center that changes according to wind speed and direction. The wind speed and direction data are obtained by digitally calculating this distance. By following a different approach than the existing techniques in measuring wind speed and direction, the data obtained in this method was compared with a real anemometer and an error analysis was performed. The relative error value was found to be 0.01685 as a result of the error analysis.
