Abstract
U radu su predstavljena opća načela te principi rada asinkronih motora. Prikazana je izvedba te analiza matematičkog modela kaveznog asinkronog motora u trofaznom sustavu. Izvedene su, korištene i analizirane posebne transformacije trofaznog u dvofazne sustave u svrhu laganije sinteze simulacijskog modela, čime se postiže manja kompleksnost samog matematičkog modela reduciranjem reda pripadajućih diferencijalnih jednadžbi i njihovih parametara. Polazište i sama implementacija zadanih transformacija u dvofazne sustave izvodi se prema principu regulacije nezavisno uzbuđenih istosmjernih motora. Korištenjem transformiranih parametara dvofaznih sustava provodi se sinteza modela asinkronog motora kao i potrebni modeli po principu vektorske kontrole asinkronog motora bez mjernih elemenata brzine vrtnje te struje rotora. Koristeći Matlab/Simulink, simulirane su i analizirane prijelazne pojave zaleta motora u praznome hodu, udarac nazivnog tereta te uzastopni udarci od 30% te do 70% nazivnog tereta nakon zaleta u praznome hodu te dinamičko kočenje istosmjernom strujom nakon zaleta u praznome hodu.
Abstract (english)
This thesis represents the root essentials and working principle of an induction motor as well as representing and analysis of squirrel cage induction motor mathematical model in three-phase system. Observing the complexity of three-phase system, three-phase to two-phase system transformations were derived and introduced in order to attain simpler synthesis of simulation model by diminishing complexity of a simulation model, i.e reducing order of differential equations and their corresponding parameters. Major idea and reference of analysis, deriving and managing special transformations to two-phase systems was arrived from fundamental regulation of separately excited direct current motors. Using two-phase transformation models, synthesis of induction motor model was shown. Using Matlab and its integrated component Simulink, induction motor transients like no load machine starting, performance under nominal load, performance under continuous load change with 30% and 70% of nominal value and DC injection braking are being simulated and measured.
