基于GPRS的電網GIC在線監(jiān)測系統(tǒng)的研究與實現(xiàn).pdf

1、華北電力大學碩十學位論文摘任石3七磁暴導致的地磁感應電流(GeomagieallyIndueedeurrents，簡稱exe)對電網的影響需要研究，實際測量是掌握電網GIC水平的直接手段，本文提出在己研制的GIC監(jiān)測裝置基礎上，開發(fā)基于GRPS的電網GIC在線監(jiān)測系統(tǒng)。在電網GIC在線監(jiān)測系統(tǒng)的設計中，利用GPRS技術實現(xiàn)了GIC數(shù)據的遠程傳輸，并將各自獨立的監(jiān)測站點的數(shù)據組織成數(shù)據網絡應用.NET技術完成了監(jiān)測系統(tǒng)后臺軟件的總體設計和

2、部分功能模塊的詳細設計。目前，開發(fā)的系統(tǒng)已經在實際電網運行使用，運行結果表明，本文設計和開發(fā)的監(jiān)測系統(tǒng)整體性能達到了預期的設計要求。關鍵詞:地磁感應電流，遠程數(shù)據傳輸，GPRS，在線監(jiān)測ABSTRACTThegeomagnetieinducedcurrent(GIC)，eausedbygeomagnetiestorms，willaffectthePowergrid.ThiseffectshouldbePaidattentiontoand
