This paper make transient simulation using atp about 110kv transmission line , then extract the fault parameter and characteristic element from the result of simulation and generate training samples and testing samples 應用電磁暫態(tài)仿真程序( atp )對110kv輸電線路電力網(wǎng)絡進行暫態(tài)仿真,對仿真結果采用傅氏算法提取故障時的參數(shù)和特征量,生成用于神經(jīng)網(wǎng)絡訓練和測試的樣本。
A novel measurement and control system ( mcs ) used in hv flameproof switchgear has been established based on the 80c196kb single - chip microprocessor , by which electrical faults such as short circuit , over - load , over - voltage , open circuit , earth leakage and so on can be automatically distinguished and processed , and with the exception of this , the insulation degree of the double screen cables is monitored on - line . the operating condition and fault parameters can be displayed in turn with liquid crystal display 該系統(tǒng)能自動判斷短路、過載、過壓、欠壓、漏電等故障,并對高壓電纜的絕緣水平進行實時監(jiān)測,大屏幕液晶顯示器實現(xiàn)了電太原理工大學碩士學位論文網(wǎng)參數(shù)的輪流顯示,通過撥碼盤輸入系統(tǒng)各項整定參數(shù),真正實現(xiàn)了保護系統(tǒng)數(shù)字化。
Many protective and monitoring functions are integrated in the system , such as pilot circuit monitoring , earth - fault monitoring , short circuit protection , over - load protection , phase symmetry and phase loss monitoring , over voltage protection , under voltage protection , motor thermal monitoring and so on . all measuring results , fault states , fault parameters and error messages of six motors controlled by the sys tem are sent to the liquid crystal display module via the existing serial data connection 該系統(tǒng)能自動轉換控制方式,具有漏電、短路、過載、斷相、欠壓、過壓、過熱等保護功能,通過觸摸式液晶顯示系統(tǒng),不僅能顯示各路負荷的工作狀態(tài)和工作參數(shù),而且能記憶其故障狀態(tài)和故障參數(shù)。
