1、基于PSCAD和MATLAB的電力系統(tǒng)電磁暫態(tài)仿真研究摘要電磁暫態(tài)的研究主要是針對電力系統(tǒng)出現(xiàn)故障時對系統(tǒng)參數(shù)進(jìn)行分析。本文根據(jù)電力系統(tǒng)的故障分析理論,運用電磁暫態(tài)仿真軟件PSCAD/EMTDC和系統(tǒng)仿真軟件MATLAB,以雙電源供電系統(tǒng)為模型分別對其進(jìn)行了單相接地、兩相相間短路及三相接地故障條件下的電磁暫態(tài)仿真分析,通過仿真結(jié)果比較,得出兩種仿真環(huán)境下的仿真波形幾乎一致,與故障分析算例基本吻合,這說明這兩種仿真環(huán)境都適用于電力系統(tǒng)的電磁暫態(tài)仿真,但在故障設(shè)置方面,PSCAD的設(shè)置更為靈活方便。同時,由PSCAD建
2、立一個簡單的交直流傳輸系統(tǒng)為模型,根據(jù)PSCAD-MATLAB接口技術(shù)原理,實現(xiàn)了接口環(huán)境下的電磁暫態(tài)仿真研究,這說明了PSCAD-MATLAB接口仿真技術(shù)在電磁暫態(tài)分析中的有效性。關(guān)鍵字:電磁暫態(tài);PSCAD;MATLAB;接口技術(shù)內(nèi)蒙古科技大學(xué)畢業(yè)設(shè)計說明書(畢業(yè)論文)ThesimulationstudyforelectromagnetictransientinpowersystembasedonPSCADandMATLABAbstractElectro-magnetictransientresearchmai
