Metoda merenja snage i energije vetra zasnovana na merenju na intervalu / Method of Power and Energy Wind Measurement based on Measurement on Interval

<p>U disertaciji je prikazan i predložen novi metod merenja snage<br />i energije vetra koji se bazira na stohastičkoj digitalnoj mernoj<br />metodi (SDMM), umesto do sada korišćene standardne sempling<br />metode (SSM). Standard za merenje brzine vetra predstavlja<br />anemometar sa šoljicama, koji na svom izlazu daje sinusni napon<br />čija su amplituda i frekvencija linearno zavisne od brzine<br />vetra. Kako su snaga i energija vetra proporcionalne trećem<br />stepenu brzine vetra, u tu svrhu se primenjuje generalizovan<br />hardver namenjen za računanje proizvoda tri ulazna signala. Zbog<br />niskog frekvencijskog opsega ulaznog signala izvršeno je<br />značajno pojednostavljenje hardvera mernog uređaja. Teorijskom<br />analizom, simulacijom, a potom i eksperimentom potvrđena je<br />hipoteza istraživanja, da se SDMM uspešno može koristiti za<br />merenje snage i energije vetra.</p> / <p>In this dissertation а new wind power and energy measurement<br />method, based on Stochastic Digital Measurement Method (SDMM),<br />was elaborated and proposed, to replace the commonly used Standard<br />Sampling Method (SSM). The standard for wind speed measurement is<br />a cup anemometer that provides a sinusoidal voltage on its output,<br />having the amplitude and frequency linearly dependent of the wind<br />speed. Since the wind power and energy are proportional to the third<br />degree of the wind speed, the general case hardware has been designed<br />for the product calculation over three input signals. The low frequency<br />range of the input signal allows for a significant simplification of the<br />measuring instrument hardware. By theoretical analysis and<br />simulation, and consequently through an experiment the hypothesis of<br />this research was confirmed - that SDMM can be successfully used to<br />measure wind power and energy.</p>
