Abstract

U teorijskom dijelu rada, predstavljen je problem i rješenje proračuna tokova snaga. Opisane su osnovne metode proračuna Gauss-Seidel i Newton-Raphson u svojem matematičkom obliku i obliku koji se koristi u rješavanju problema tokova snaga. Opisane su i metode DLF (eng. Decoupled Load Flow) i FDLF (eng. Fast Decoupled Load Flow). U praktičnom dijelu, na IEEE test mreži 24,48 i 72 čvorišta, uspoređene su osnovne metode u pogledu brzine izvođenja jedne iteracije, ukupnog proračuna, te ovisnosti brzine o zadanoj točnosti. Provedeni su proračuni određivanja optimalnog faktora ubrzanja, te usporedba konvergencija metoda. Usporedba rezultata i preporuka korištenja, provedena je za istosmjernu metodu simuliranjem različitih pogonskih stanja koja su i komentirana.

Abstract (english)

The theoretical part describes problem and solution of load flow in power system. Basic power flow methods Gauss-Seidel and Newton-Raphson are described in their mathematical and practical forms. Also are described DLF (Decoupled Load Flow) and FDLF (Fast Decoupled Load Flow) methods. In practical part, IEEE test 24,48,72 node network is used to compare basic methods in terms of calculation speed: on execution of one iteration, entire calculation and on given accuracy influence. Also is analyzed optimal acceleration factor for every network, and convergences of methods. Comparison of the results and recommendations of use was performed for direct method (DC) simulating various operating conditions that are also commented.
