1、500kV變電站無人值班綜合自動化控制系統(tǒng)改造研究摘要進入21世紀以來,電力系統(tǒng)芷向高參數(shù)、大容藿、超高雒快速發(fā)展,500kV宅弼毫形成環(huán)弼笄或雋我國憊潮鵑主弼粲。遺著邂力體嬲改葦豹逐濠渫入和山農(nóng)電力系繞奴模鮑不叛擴大,500kV電鄹建設(shè)和運行管理中的許多具體問題需要我們加以研究和解決。本文針對山東500kV電網(wǎng)目前建設(shè)和運行管理狀況,甜500kV變電站無人值班練臺蠢動傀系統(tǒng)設(shè)計與安現(xiàn)避行了深入的研究。本文先在憨結(jié)了當蘸由衷毫囂500kv變毫始靜逡行管理狀璦轉(zhuǎn)基礎(chǔ)上,對山東500kV變電站實施無人值班綜合自
2、動化系統(tǒng)的可行蝕和必要性進行了分析,并對500kV變電站無人值班綜合自動化系統(tǒng)的實現(xiàn)進行了規(guī)劃。然后對實現(xiàn)500kV變電站無人值班的綜合自動億系統(tǒng)滋行了設(shè)計和實施,對500kV交電菇無入值班綜合舀動純系統(tǒng)黔主按制戇及分控剃站遴行了主要系統(tǒng)的懿各秘實現(xiàn),包撂實現(xiàn)500kV變墩站天人德班的輔助系絞如變電站的在線監(jiān)測、調(diào)度自動化系統(tǒng)及運彳予監(jiān)控中心的輔助決策等的構(gòu)成避行了分析。娥后給出了500kV變電站綜合自動化系統(tǒng)無入值班的運行監(jiān)控中心、集控站及操作酞的運行管璃模式,戳適應(yīng)500kV變電站綜合自耱伍系統(tǒng)集中靛按
