diplomsko delo univerzitetnega študijskega programa
Abstract
V diplomski nalogi je opisan šolski model sistema za proizvodnjo električne energije z rotacijskim strojem. Izpeljan je matematični model asinhronskega stroja, ki je uporabljen za simulacijo in kasneje vodenje. Dvostransko napajani asinhronski stroj, ki je z rotorske strani napajan z enosmernim tokom, se obnaša kot sinhronski generator. Predstavljeni so posamezni deli sistema za proizvodnjo energije, računalniško vodeno sinhronizacijsko stikalo, transformator za dvig napetosti in regulacijska zanka za regulacijo jalove moči. Predstavljeni so tudi problemi sinhronizacije sistema na omrežje in sinhronizacijska logika. Razložena so mogoča obratovalna stanja generatorja. Predstavljena sta algoritma avtomatske sinhronizacije sinhronega generatorja v omrežje ter regulacija jalove moči. Podana je primerjava med rezultati simulacijskih izračunov in rezultati meritev na laboratorijskem sistemu med stacionarnim obratovanjem in med prehodnimi stanji.

Secondary title: |
Laboratory Power Plant Model |
Secondary abstract: |
The thesis describes a laboratory realization of electrical power generation system based on a rotary electric machine. A mathematical model of an induction machine is derived to be used in the simulations and in control design. The doubly fed induction machine, whose rotor winding is supplied with direct current, behaves as a synchronous generator. Presented are individual parts of the discussed electric power generation system, computerized synchronization switch, transformer for voltage rise, applied reactive power control, synchronization logics and problems related with synchronization to the grid. Proposed are the applied algorithm for synchronization to the grid and a simple reactive power control algorithm. The results of measurements and simulations are compared for the steady-state and transient operating conditions of discussed power generation system. |
