Abstract
U ovom radu prikazane su strujno-naponske prilike laboratorijskog mrežnog fotonaponskog sustava. Rad se sastoji od teoretskog i praktičnog dijela. U teoretskom dijelu opisan je mrežni fotonaponski sustav, te način na koji se sunčeva energija provodi do distribucijske mreže. U praktičnom dijelu rada provedena su mjerenja snage fotonaponskog modula s istosmjerne i izmjenične strane, te je napravljena njihova usporedba. Uz pomoć mjernih rezultata prikazani su dijagrami uz koje se nalaze i njihova obrazloženja. Mjerenja su provedena u vremenskom periodu od pet dana, s tim da jedan dan nedostaje zbog poteškoća s mjernom opremom. U preostala četiri dana nalaze se prikazi i sunčanih i oblačnih dana, što se jasno vidi iz predloženih dijagrama. Dok je kod dijagrama sunčanih dana karakteristika obla, bez velikih oscilacija, kod oblačnih dana karakteristika je šarolika, to jest s velikim oscilacijama. Osim toga, također se vidi da istosmjerna i izmjenična snaga nisu jednake, što je rezultat DC/AC pretvorbe te gubitaka koji se javljaju u pretvaračkim komponentama.
Abstract (english)
This paper presents the current-voltage conditions of the laboratory network photovoltaic system. The work consists of a theoretical and practical part. The theoretical part describes the network photovoltaic system and the way solar energy is applied to the distribution network. In the practical part of the work, measurements of the photoconductor power of the DC and AC side were performed and their comparison was made. With the help of the measurement results, the diagrams and their explanations are presented. The measurements were carried out over a period of five days, with one day missing due to difficulty with the measuring equipment. For the remaining four days, there are views of both sunny and cloudy days, as can be seen from the accompanying diagrams. While in the diagram of sunny days the characteristic is rounded, without large oscillations, on cloudy days the characteristic is variative, that is, with large oscillations. In addition, it is also seen that DC and AC power are not equal, as a result of DC / AC conversion and losses occurring in converter components.
