中文摘要 | 本文主要探討單、三相感應電動機、保護電驛和變壓器在諧波電壓源下之影響, 其中包含因諧波使得電驛可能的誤動作,變壓器、感應電動機額外增加之損失及溫昇,並進 一步推算電動機溫昇與壽命老化之關係。變壓器、感應電動機諧波域之數學分析模式已建立, 以驗証及預測其受諧波影響之實際響應,本研究採用電子計算機去控制多功能電源產生器, 以產生實驗所需之諧波電壓,經由測試結果顯示,感應電動機在不同組成之諧波電壓源下, 可利用權重諧波因數評估諧波所造成之影響;而在總電壓諧波失真率10%以下,機電式電 驛受諧波電壓之影響可忽略,其餘測試結果亦在本文詳述之。 |
英文摘要 | This paper will discuss effects of harmonic voltage on the operation of induction motors, protection relays and power transformers. It covers the possible misoperation of protection relays, the additional losses, temperature rise characteristics of power transformer and induction motor which are caused by harmonics. Furthermore, life deterioration of induction motors can be estimated. To verify and predict the actual response of harmonic effect an analytic mathematics model in harmonic domain is established, A PC-based Universal Programmer/Controller is being utilized to generating harmonic voltage. It shows that the effects of different combination of harmonic voltage source to induction motor can be evaluated by weighted harmonic factor. The protection relay with negligible effect for THDv lower than 10% have been observed. The more detail testing methods and results also have well described in this paper. |
