Přesná měření na fotovoltaické elektrárně pomocí elektronického wattmetru z pohledu vyhodnocení generovaného výkonu a účinnosti měniče

Abstract

This bachelor’s work deals with development of applications for the accurate measurement of electrical power generated by the photovoltaic power plant and evaluate the effectiveness of deployed converters. In the theoretical part of the thesis is an introduction to photovoltaic cells, inverters and virtual instrumentation. The application was used to evaluate the effectiveness of inverters Sunny Boy SWR 3000 for photovoltaic power VSB-TU Ostrava. For measuring were used Meters Yokogawa WT230. Data was stored in a file and subsequently evaluated. The work presents the results of measurements with an evaluation of the effectiveness of deployed inverters. The conclusion outlines the possibilities of further development of the application, which is due to the concept of virtual instrumentation easily extensible.
