中文摘要 | 本論文使用時間步距耦合有限元素狀態空間(TSCFE-SS)模型技術,以評估脈波寬度調變(PWM)載波頻率及電壓驟降對變速驅動器之感應馬達特性影響。本計畫中應用Ansoft-EM軟體之時間步距耦合有限元素狀態空間(TSCFE-SS)技術功能模擬出由於電機之磁能電路結構及繞阻設計安排所引起磁性非線性及空間諧波成分、變頻器電力電子開關切換所導致時間諧波成分、時間諧波及空間諧波間之合成交互作用等效應。變速驅動器之感應馬達性能模擬結果顯示與電流、轉矩平均值、電壓驟降息息相關。此外,本論文將計算關於脈波寬度調變(PWM)及電壓降對感應馬達的歐姆電阻及鐵心損失之影響。 |
英文摘要 | In this paper, a Time-Stepping Coupled Finite-Element State-Space (TSCFE-SS) method of Ansoft-EM software package is used for assessing the effects of pulse width modulation (PWM) excitation on characterization of induction motors in adjustable-speed drives. The technology applied in this paper is capable of modeling the effects of magnetic non-linearities and space harmonics due to the machine magnetic circuits’ topology and winding layouts, time harmonics resulting from power-electronic switching of inverters, as well as the synergistic interaction between these time and space harmonics. The simulation results of performance of induction motors in adjustable- speed drives are shown to correlate well with current waveforms and torque averages. Furthermore, the paper investigates consequent effects of geometry or magnetic circuit and PWM excitation on ohmic and iron core losses in induction motors. |
