電力同步網(wǎng)中，銫原子鐘和銣原子鐘為各區(qū)域電網(wǎng)管理中心和各大型電站的電網(wǎng)提供高精度時間基準。電力時間同步系統(tǒng)從2004年開始進入我國電力系統(tǒng)，主要應(yīng)用在電廠、變電站及電調(diào)中心，保障了電網(wǎng)安全穩(wěn)定運行。國家電網(wǎng)于2008年發(fā)布了《國家電網(wǎng)公司輸變電工程典型設(shè)計－變電站二次系統(tǒng)部分》標準，要求500kV、220kV變電站需配置時間同步系統(tǒng)。國家電網(wǎng)近年來還提出建設(shè)堅強智能電網(wǎng)的規(guī)劃，至2020年***建成統(tǒng)一的“智能電網(wǎng)”，而電網(wǎng)時間同步是實現(xiàn)智能電網(wǎng)信息同步的基礎(chǔ)和不可或缺的前提。2009年9月，國家正式確立“天地互備，以北斗為主的電力授時體系”，以擺脫對GPS授時的依賴，隨著北斗授時體系在我國的***展開和建設(shè)，我國電力系統(tǒng)對時間頻率產(chǎn)品的需求持續(xù)快速增長。信息時代的到來，高精度時間頻率已成為國家科技、經(jīng)濟、***、***和社會生活中至關(guān)重要的一個參量。四川NTP網(wǎng)絡(luò)授時衛(wèi)星授時設(shè)備/裝置批量按需定制</p><p

時間頻率設(shè)備（成都可為科技股份有限公司）從產(chǎn)品形態(tài)上，時間同步產(chǎn)品目前主要分為兩種：時間同步板卡及模塊、時間同步設(shè)備。時間同步板卡及模塊，一般以標準時間頻率信號為參考，產(chǎn)生、保持、分發(fā)系統(tǒng)或設(shè)備所需要的各種時間和頻率信號，通常在通信基站、***領(lǐng)域應(yīng)用比較多；時間同步設(shè)備，就是通常所說的時間服務(wù)器，一般通過接收北斗/GPS/標準時間信息，產(chǎn)生、保持時間頻率信號，并通過有線或無線方式進行接收或傳遞，為系統(tǒng)提供多種形式的時間和頻率信號，產(chǎn)品主要應(yīng)用于通信、電力、交通、**等領(lǐng)域。 </p> <p> 高精度授時是實現(xiàn)時間同步的關(guān)鍵，世界主要發(fā)達國家都高度重視授時系統(tǒng)建設(shè)。1957年，美國在東海岸建成了***個羅蘭-C導(dǎo)航授時臺鏈，開展利用長波進行無線電導(dǎo)航、授時服務(wù)；1973年，美國開始建設(shè)全球定位系統(tǒng)（GPS），1995年4月宣布達到全運行能力，1996年宣布GPS為軍民兩用系統(tǒng)。目前，由于北斗3代已在2020年正式投入組網(wǎng)運行，標志中國北斗與GPS授時成為當(dāng)前國際上將得到***使用的時間同步技術(shù)。四川時間服務(wù)器衛(wèi)星授時設(shè)備/裝置廠家現(xiàn)貨</p><p>
