本文針對單翼大撓性太陽帆板衛星，建立了撓性衛星動力學模型，在此基礎上，研究了地球捕獲、剛體衛星三軸姿態穩定、充液衛星三軸姿態穩定問題。On the base of the fujian power system that has the special configuration of " large power generator with small power system " in 2000, constructs power system models of fujian and fujian interconnected with other parts, does a lot of calculation and analysis and simulation, researches the security mechanism and rule of the fujian special power system interconnected with large power system. the above connection can keep security and stability and can make obvious benefits, but when the transmission power reach to excessive quantity the main power grid will increases interconnected flow - in or flow - out exchange power load. the power operation state tended to instability ; the infirmable interconnection make s the damp infirmable
本文以2000年前後具有「大機組小電網」特殊結構的福建電力系統為背景，建立了福建電力系統及其與外部互聯的數學模型，開展大量的模擬計算分析，研究了「大帆組小電網」電力系統與大容量電力系統互聯偏弱的安全穩定性的機理和規律：前述互聯可以安全穩定運行，取得顯著效益，當傳輸功率達到一定量后，主網架增加了送出或吸收互聯交換功率的負載，系統運行狀態向穩定性水平有所下降的方向轉移；聯絡偏弱使阻尼偏弱，聯絡線小幅低頻振蕩和大幅低頻振蕩易被激發，聯絡線一旦重載斷開，系統高周或低調嚴重。Stability analysis and design of steel roofing of qingdao international sailboat center
