| Summary: | 碩士 === 國立高雄第一科技大學 === 機械與自動化工程所 === 95 === This research aims is devoted to develop a maximum power point tracking and remote monitoring system. In fact, meter display is the only energy-generated information provided by traditional photovoltaic system. It lacks the functions of data recording and analyzing, and this remains a future obstacle. Therefore, developing a Data Acquisition System is an important issue. This proposed system could allow users to acquire and analyze historical record of the photovoltaic system without physical access. The thesis distinguishes that measured output power doesn’t operate in respect to its environment. In reality, it doesn’t come close to the maximum power point. This research uses protuberant-observation method to acquire the maximum power output of the photovoltaic system. The output power can be obtained by calculating the output voltage and current of the photovoltaic system. Furthermore, use the tendency of the output power as a performance index to adjust the duty cycle of the buck-boost converter to indicate the tracking to maximum power. The experimental results have proved that this photovoltaic system can be operated in the nearby environment of the maximum power point to improve the whole energy generated system efficiency by operating at different conditions.
