Abstract

V diplomskem delu je predstavljen asinhronski stroj, ki je uporabljen kot asinhronski generator v otočnem načinu delovanja. Za izračun parametrov sistema je bilo potrebno izvesti meritve objekta, kjer bo asinhronski generator uporabljen. Regulacija napetosti je izvedena s pomočjo Siemensovega krmilnika. Napetost sistema je preko transformatorja znižana na dovoljeno vhodno napetost krmilnika. Krmilnik ob znižanju merjene napetosti programsko vključuje komplet kondenzatorskih baterij za zagotavljanje standardne napetosti. Ob pojavu previsoke napetosti krmilnik izvede obraten proces in izklopi komplet kondenzatorskih baterij. Za regulacijo frekvence skrbi pogonski stroj, ki zagotavlja konstantne vrtljaje na osi asinhronskega generatorja. Prenos med pogonskim strojem in asinhronskim generatorjem je izveden preko dveh primerno izbranih jermenic in jermenov. Sistem je ustrezno tokovno in napetostno varovan.

Secondary title: THE USE OF INDUCTION GENERATOR IN THE ISLAND MODE
Secondary abstract: Here in this diploma, induction machine is examined. It is used as an induction generator in isolated network. For right parameters of machine, measurements of the facility were made. The regulation of voltage is made by Siemens controller. Basic voltage is transformed to lower level and connected to the input of controller. For constant level of voltage controller is connected or disconnecting with capacitor battery on the basis of input level. If the voltage is to low, controller is putting in a package of capacitor battery, otherwise the process is reversed. Regulation of frequency is made by a tractor, which provides constant torque to the shaft. Connection between the induction machine pulley and the prime mover pulley is made by pulley belt. System is appropriate current and voltage protected.
