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