Abstract
Matematičko modeliranje regulacijskih sustava u hidroelektrani se sastoji od opisa dijelova hidroelektrane pomoću nelinearnih diferencijalnih jednadžbi te uporabe programskog paketa Matlab/Simulink. Rad se sastoji od 5 glavnih poglavlja. Uvod obuhvaća prikaz opsega rada i temeljne pojmove vezane uz podjelu hidroelektrana te opis visokotlačne derivacijske hidroelektrane. U 3. poglavlju su detaljno razrađeni nelinearni matematički modeli svih elemenata hidroelektrane od zahvata do priključka na elektroenergetski sustav te temeljem tih matematičkih modela su definirane strukturne blokovske sheme simulacijskih modela na Matlab/Simulinku. U 4. poglavlju su detaljno opisani elementi HE Zakučac te su izračunati i prikazani svi ulazni parametri potrebni za simulacijski model hidroelektrane. U 5. poglavlju je ispitano ponašanje hidroelektrane pri skokovitim promjenama opterećenja u režimu sekundarne regulacije i u otočnom radu, te pri promjeni referentnog napona uzbude. Dobiveni rezultati simulacije prikazaju: dinamički tlak pred turbinom, protok kroz tlačni cjevovod i turbinu, brzinu vrtnje agregata, mehaničku snage turbine, radnu i jalovu snage generatora, napon, struju i kut opterećenja generatora
Abstract (english)
Methodology of mathematical modeling of dynamic control system in hydro power plant is made up of non-linear differential equations and use of software Matlab/Simulink. This work consists of five chapters. The objective of this work is elaborated mainly in the first part. Non-linear mathematical models of all elements in hydro power plants are detailed described at third chapter. The basic blocks of the simulation model are: tunnel, surge tank, penstock, water turbine, turbine governor, synchronous generator and excitation control. Hydro power plant „Zakučac“ has been described and input parameters are calculated and shown at fourth chapter. The fifth chapter is shown response of hydro power plant at load step changes in secondary control and island operation regime with changes in the excitation reference voltage. Simulation results show: dynamic pressure before the turbine , fluid flow through penstock and water turbine, generator speed, mechanical power of turbine, active and reactive power, voltage, current and load angle of generator
