| Abstract | U ovome radu prikazana je primjena i usporedba P i PI algoritma u sekundarnoj regulaciji
frekvencije i djelatne snage elektroenergetskog sustava. Prvo su opisane vrste regulacije u
elektroenergetskom sustavu, te su navedene prednosti i nedostaci pojedinih razina regulacije
frekvencije i djelatne snage, s naglaskom na sekundarnu regulaciju.
Zbog mogućnosti usporedbe dvaju navedenih algoritama regulacije, razvijen je linearni
model elektroenergetskog sustava. Prikazani model se sastoji od jednog regulacijskog područja,
a svi njegovi sastavni dijelovi su detaljno opisani.
Na linearnom modelu elektroenergetskog sustava izvršena su simulacijska ispitivanja.
Napravljena je usporedba između P i PI algoritma sekundarne regulacije. PI algoritam se
pokazao boljim od P algoritma iz više razloga. Glavni razlog je da u potpunosti kompenzira
djelovanje poremećajne veličine, a osim toga oscilacije regulirane veličine nakon djelovanja
poremećaja su osjetno manje, te je brzina regulacije veća. |

| Parallel abstract (English) | This paper shows the application and comparison of a P and a PI algorithm in the load
frequency control of a power system. Firstly, categories of control in the power system are
described. Afterwards, the advantages and disadvantages of different levels of load frequency
control, with an emphasis on secondary regulation, are presented.
For the purpose of testing the two aforementioned control algorithms, a linear power
system model is designed. The presented model is composed of a single control area and all of
its components are explained in detail.
The simulation was conducted on a linear power system model, on which the comparison
of the P and PI control algorithm was obtained. The PI algorithm is superior to the P algorithm
for several reasons. In other words, the main reason is that the PI algorithm not only fully
compensates the effect of disorders, but the oscillations of the controlled variable are
significantly less perceptible after the disturbances, and the controlling speed is greater. |
