20.500.12556/DKUM-36877 ELEKTRIČNI GENERATORJI ZA VETRNE ELEKTRARNE WIND TURBINE GENERATORS Električni generatorji so naprave, ki pretvarjajo mehansko delo v električno energijo. Električne generatorje delimo glede na obliko napetosti na sponkah na izmenične in enosmerne. S pomočjo programskega paketa Matlab/Simulink smo analizirali izmenični asinhronski generator v sklopu vetrne elektrarne priključene na omrežje, ki nam je zagotavljalo jalovo moč potrebno za vzpostavitev magnetnega polja v generatorju. Pri analizi smo kot spremenljivko uporabili hitrost vetra, opazovali pa smo naslednje parametre: delovno, jalovo in navidezno moč generatorja, hitrost rotorja, električni in mehanski vrtilni moment, električno napetost, električni tok, ter spreminjanje kota lopatic vetrne turbine. Electric generators are devices that convert mechanical work into electricity. According to the form of voltage at the terminals electric generators are divided into the AC and DC generators. By using Matlab/Simulink, we analyzed the AC induction generator within the wind farm that is connected to the network, which provide the necessary reactive power for excitation of the generator. In the analysis the wind speed was used as a independent variable, and we observed the following parameters: real, reactive and apparent power of the generator, rotor speed, electrical and mechanical torque, electrical voltage, electrical current and changing the angle of wind turbine blades. energija vetrna turbina generator energy wind turbine generator true true false [A.
