This thesis carries out studies aiming at the impact of load characteristics and on load tap changer on voltage stability 本文針對負(fù)荷特性和有載調(diào)壓變壓器對電力系統(tǒng)靜態(tài)電壓穩(wěn)定性的影響展開研究。
Powertransformers with off circuit tap - changer resp . on load tap changer ; main dimensions and accessories , 2000 to 10000 kva and up to insulation class 110 n 分別帶斷路分接開關(guān)或載荷分接開關(guān)的功率變壓器. 2000
The impact of load characteristics and on load tap changer on static voltage stability is analyzed with the methods based on v - q and v - p curves , and the phenomenon of voltage stability voltage instability and voltage collapse are studied with steady - state simulation . finally the thesis presents the essential explanations of both voltage stability and the mechanism of voltage collapse . xu yonghua ( electrical engineering ) directed by prof 通過電壓?功率曲線分析法定性分析了不同負(fù)荷特性和有載調(diào)壓變壓器對靜態(tài)電壓穩(wěn)定性的影響,并通過靜態(tài)仿真法從物理現(xiàn)象上研究了電壓失穩(wěn)和電壓崩潰現(xiàn)象,最后針對這些現(xiàn)象給出了關(guān)于電壓穩(wěn)定、以及電壓崩潰的本質(zhì)解釋。
