Abstract

Granice rada sinkronog generatora često se temelje na stacionarnom modelu koji koristi konstantne sinkrone reaktancije. Zbog zasićenja i krosmagnetizacijskog efekta u praksi su te granice promjenjive i ovisne o radnoj točki stroja. Izrađena je aplikacija u razvojnom okruženju LabVIEW za prikaz pogonske karte sinkronog generatora s promjenjivim granicama koje su eksperimentalno određene za generator snage 83 kVA. Rad aplikacije i njena funkcionalnost testirana je u laboratorijskim uvjetima pri promjenjivom naponu.

Abstract (english)

Operation limits of a synchronous generator are based on a steady-state model with constant reactances in d and q axis. Due to saturation and crossmagnetizing effect in real applications those limits are not constant and change as the operating point change. An application has been developed in LabVIEW that shows a P-Q diagram with variable operation limits. Those limits are experimentally determined on an 83 kVA synchronous generator. The application and its functionality were tested in a laboratory environment under different voltage levels.
