鑒於研究文獻中,估計感應馬達的磁化電抗均需使用額外的感測器、有限元素分析法、頻譜分析法或遞昇加壓測試法,並非簡單而有效的估測方法;而為建立電力系統模型,需要現場實際估測一台感應馬達時,常面對因為馬達製造時未先行量測,價格昂貴,無法安裝額外感測器,或變頻/變電壓方式不易進行,而無法進行非線性模型的研究模擬。
基於上述現實問題,估測一台現成的馬達參數及模型的建立,對於工業界而言,常造成困擾,尤其是面對電力系統的暫態分析時,可能會因為馬達運轉於飽和區,線性模型常無法提供精確的模擬而造成偏差的結論,甚至誤導。因此,本論文針對上述的想法,主要分成二部分:
首先,針對感應馬達模型模擬中的磁化電抗估計提出簡單而實用的方法,以便應用於中/高壓感應馬達現場實際估測,以達到分析該感應馬達運轉特性的目的。再根據馬達製造廠所能提供的測試數據,將一個實際線上使用高壓馬達進行模型化,並利用電路耦合的方式與電力系統連接,避免傳統使用數學演算式模擬馬達所造成無法直接結合電力系統其他元件的缺點。
其次,當高壓馬達突然喪失電源時,在不同的起始條件及運轉情形下,本論文針對轉子慣性產生的發電機效應加以評估,提出高壓馬達/發電機效應產生時所造成的影響及各種運轉參數變化情形,比較在不同的線路電容存在狀況下所造成的差異性,並藉著與實際紀錄器產生的電壓波形印證比對,以釐清少見的無電源孤島系統中殘存過電壓的現象。
Saturated reluctance identification of induction motor can be implemented by additional sensor, finite-element method, spectrum analysis, or step voltage test in the research accounts. But it is not easy to implement in the field evaluation when we need to build up the power system model, because of the factory parameter absent, expansive cost, extra sensor installation, or variable voltage and frequency.
To be concerned with practicality, it is always inconvenient to build up simulation for the end user. The linear model of motor can’t provide the simulation answer accurately when models run into saturated during power system transient. Accordingly, this thesis discuss two paragraphs as following:
First, This thesis introduces a simple and practical method base on the manufacturer instruction manual to estimate the saturated reluctance of high / medium voltage induction motor in modeling. And we can analyze the motor dynamic characteristic by using the induction motor d-q-0 model directly, in place of traditional mathematical power equations.
Moreover, we can evaluate the motor-generation reaction because of the rotor inertia due to loss of voltage. To identify the discrepancy between numeral situations what the line capacitor existed or not. Besides, we can explain the existing voltage after power system break down by comparing the simulation result with recorder chart.
