摘要

本論文旨在推導出雙饋式可變速抽蓄機組之數學模型表示式，以應用於動態模擬分析。採用線繞式交流激磁轉子之改良型感應機模型以及磁場導向控制理論，作為雙饋式可變速抽蓄機組之模型研究與分析。藉由分離控制轉子交軸電壓及直軸電壓，獲得輸出有效功率及無效功率。然後以旋轉電機的搖擺方程式為基礎，結合轉子轉動慣量迴轉運動方程式推導其動態特性。最後，進行時間領域模擬，並與實例比較分析動態特性，以驗證本模型之正確性。

This paper derives the mathematical models of doubly-fed adjustable-speed pumped storage units (DFASPSUs) to be utilized in the dynamic simulation analysis. It adopts the improved induction machine model with AC excitation on the wire-wound rotor as well as the field-oriented control theory for the study and analysis of DFASPSU models. First, the rotor excitation voltage is separated into two components, i.e., the q-axis voltage and d-axis voltage, so as to control both of the output active and reactive powers. Next, a dynamic model of DFASPSU is derived using the swing equation of rotary electric-machine and the equation of motion of rotor rotating mass. Finally, computer simulation is carried out to compare its results with practical examples in terms of dynamic characteristics for verifying the correctness of the proposed models.
