  •   本論文旨在研究一台單相感應發電機併聯至市電運轉之特性,使用之數學模型包含單相感應發電機之暫態及穩態模型。本論文在市電併聯型單相感應發電機之穩態研究方面,分別針對發電機的轉速、激磁電容值、市電端電壓、市電電壓之頻率、傳輸線阻抗、發電機之磁化電抗對系統特性之影響做一詳細之討論;在動態研究方面,則針對感應發電機瞬間連接市電以及與市電解聯時的起動暫態電流特性、對系統及感應機所造成之影響等做評估分析。論文的實驗是使用實驗室一部由直流馬達所驅動之1/3馬力、110/220 V、60 Hz、4極、額定轉速1730 rpm之單相感應機來完成,由所量測的結果與理論模擬結果相互比較,以驗證所使用電機模型、參數的可用性以及所分析結果之正確性。

      This thesis analyzes characteristics of a single-phase induction generator (SPIG) connected to a utility grid. Both transient and steady-state equivalent-circuit models of the studied SPIG are established.

      The variations of rotor speed, capacitor value, utility grid voltage, frequency of utility grid voltage, line impedance, and machine magnetizing on steady-state performance of the studied SPIG are investigated. Dynamic characteristics of the studied SPIG subject to a sudden connection to and a sudden disconnection from the utility grid are examined.

      Experimental results obtained from a 1/3 hp, single-phase, 110/220 V, 60 Hz, 4 poles, rated speed of 1730 rpm induction machine driven by a DC motor are compared with the simulated results to validate the effectiveness and feasibility of the proposed models and the analyzed results.
