中文摘要 | 暫態穩定度控制之目的,在於針對電力系統中即將失去同步的機組,迅 速採取有效的控制措施,以避免系統失去穩定。電力系統暫態穩定度控制問題除 需設計一可靠的控制器外,控制器最佳位置之選定,亦是一件相當重要的課題。 本論文中將發展一套控制器最佳位置選定的方法,首先提出一種新的全域擾動 法,以觀察每部發電機受擾動後之振盪模式。在新的全域擾動法中,發電機之擾 動量,除以各發電機慣性常數為比例基準外,亦考慮發電機運轉點之影響程度, 以克服傳統方法中,因運轉點差異所形成之非均等擾動。其次,提出以速度差為 基礎的同行機組辨識(coherency identification)準則,並以每一部機組之速度差為輸 入圖樣,發展以可適性共振理論(adaptive resonance theory,簡稱ART)網路實現K一 平均演算法之同行機組辨識方法,將多機電力系統分解成數個次系統 (subsystems),以分析各機組問的影響程度。並以此作為選定控制器最佳位置之參 考依據,以減少冗長的搜尋時間。此外,因本文所提之同行機組辨識法僅需每部 機組的速度資料,故可適用於不同動態特性的發電機,使其在電力系統動態等效 分析上深具應用價值。 為評估本文所提方法之實用性,本研究以兩個多機系統:34部機組的臺電系統及 10部機組的新英格蘭系統為模擬測試之對象。經由一系列的模擬和驗證後,其結 果令人相當滿意。 |
英文摘要 | This study was based mainly on the published domestic and international researchpapers referred to HFC-134a . A simulation method of subtituting R-12 by the similar set ofenvironmental conditions was employed to make a theoretical study . In this way we hoped tobe familiar with the new refrigerant and enhance the ability to apply it in technologicaldesign once it is introduced in the future. When the results of thermodynamic property analyses were compared,it was foundthat general property of the new refrigerant was very sinilar to that of currently used in R-12refrigerator. And it was proved that direct substitution of R-134a in the R-12 refrigertor wasfeasible, however , the pressure of condenser was higher , the pressure difference becomeswider , the total heat of condenser was increased and the coefficient of performance wasredued . In the other words , to achieve the same refrigeration capeity , the one with newrefriant would consume more energy than that of R-12. |
