                      特高壓

                      特高壓是指電壓等級在交流1000千伏及以上和直流±800千伏及以上的輸電技術,具有輸送容量大、距離遠、效率高和損耗低等技術優勢。2004年以來,國家電網公司聯合各方力量,在特高壓理論、技術、標準、裝備及工程建設、運行等方面取得全面創新突破,掌握了具有自主知識產權的特高壓輸電技術,并將特高壓技術和設備輸出國外,實現了“中國創造”和“中國引領”。截至2019年6月,特高壓建成“九交十直”、核準在建“三交一直”工程,已投運特高壓工程累計線路長度27570公里、累計變電(換流)容量29620萬千伏安(千瓦)。特高壓交流和直流分別榮獲2012年度、2017年度國家科技進步特等獎。特高壓輸電通道累計送電超過11457.77億千瓦時,在保障電力供應、促進清潔能源發展、改善環境、提升電網安全水平等方面發揮了重要作用。
