Abstract
U ovom diplomskom radu su na eksperimentalnoj razini analizirane MPPT metode za PV sustav sa silaznim istosmjernim pretvaračem, programabilnim trošilom i baterijama. U analizi su razmatrane dvije izravne MPPT metode (P&O i IC) i dvije neizravne MPPT metode (metoda konstantnog napona i metoda fiksnog faktora vođenja). Najprije su opisane osnovne značajke i vrste PV modula te utjecaj promjene osunčanosti i temperature na karakteristike snage PV modula. Nadalje je opisan silazni istosmjerni pretvarač i režim rada koji je korišten u analizi, a potom su obrađene korištene MPPT metode i njihovi algoritmi. Zatim su pomno opisani svi elementi i parametri korišteni za realizaciju laboratorijske makete. Kao emulator PV modula korišten je programabilni istosmjerni izvor, dok je za simulaciju opterećenja korišteno programabilno AC/DC trošilo kojemu su paralelno spojene olovno-kiselinske baterije. Model upravljačkog algoritma napravljen je u MATLAB Simulinku, uz korištenje odgovarajućih blokova iz dSpaceove biblioteke za akviziciju mjerenih signala i generiranje upravljačkih PWM impulsa, koji omogućuju izvođenje algoritma u realnom vremenu pomoću kartice DS1104. Na samom kraju su prikazani i prokomentirani snimljeni dinamički eksperimentalni odzivi za razmatrane MPPT metode i pripadajuće statičke karakteristike te su usporedbom dobivenih rezultata utvrđene najperspektivnije MPPT metode za razmatrani sustav.
Abstract (english)
In this graduate thesis, MPPT methods for a PV system containing a DC-DC buck converter, programmable electronic load, and batteries are analyzed at the experimental level. Two direct MPPT methods (P&O and IC) and two indirect MPPT methods (constant voltage method and fixed duty cycle method) were considered in the analysis. First, the basic characteristics and types of PV modules are described, as well as the influence of the variation in irradiance and temperature on the respective power characteristics. The DC-DC buck converter and the corresponding operating mode used in the analysis are further described, followed by the discussion of the considered MPPT methods and the respective algorithms. Then all the elements and parameters used for the realization of the laboratory model are carefully specified. A programmable DC source was used as an emulator of the PV module, whereas a programmable AC/DC electronic load was utilized to simulate the load, to which lead-acid batteries were connected in parallel. The control algorithm was created in the MATLAB Simulink environment by using the appropriate blocks from the dSpace library to acquire the measured signals and to generate the PWM pulses, which allow for real-time execution of the algorithm using the DS1104 card. Finally, the dynamic experimental responses recorded for the considered MPPT methods and the corresponding steady-state characteristics are presented and commented on, whereas the most promising MPPT methods for the considered system are determined by confronting the obtained results
