500kv變電站畢業(yè)設計

1、長春工程學院畢業(yè)設計（論文）摘要本畢業(yè)設計是500kV（50022035）變電站工程電氣部分初步設計。其中500kV、220kV側采用GIS方案，為了保證供電的可靠性和一次性滿足遠期負荷的要求，按照遠期負荷規(guī)劃進行設計建設，從而保證變電站能夠長期可靠供電。根據畢業(yè)設計任務書的要求，綜合所學專業(yè)知識及變電站設計相關書籍的有關內容，設計過程中完成了主變選擇、電氣主接線的擬定、短路計算、電氣設備選擇、配電裝置的規(guī)劃、繼電保護和自動裝置的規(guī)劃和

2、防雷保護的規(guī)劃等主要工作。并且繪制了一套電氣圖紙（電氣主接線圖、平面布置圖、配電裝置斷面圖）。關鍵詞500kV變電站GIS方案電氣主接線配電裝置AbstractThisgraduatedesignthesisisa(50022035)kVadecliningtopresstochangetogivegetanelectricshockanelectricitypartsoffirststepsdesign.Fthesakeofdepen
