本發明屬于電廠時間(jian)同步網絡(luo)，具體涉及一種適用于電廠數(shu)字化控制(zhi)系(xi)統的高可靠時鐘授時系(xi)統。

背景技術：

1、精確(que)的(de)時(shi)間(jian)頻率同步(bu)是智(zhi)慧(hui)電(dian)網(wang)的(de)關鍵支撐技(ji)術(shu)。基(ji)于(yu)衛星的(de)授(shou)時(shi)技(ji)術(shu)由于(yu)具有廣泛(fan)的(de)覆蓋范圍、便捷的(de)接入(ru)及(ji)高(gao)效(xiao)的(de)性(xing)能(neng)，已經成為了當前電(dian)力系統的(de)主(zhu)流(liu)授(shou)時(shi)方(fang)式。然而，由于(yu)衛星授(shou)時(shi)技(ji)術(shu)采用(yong)無線電(dian)傳(chuan)播測距體制，故而在諸如發電(dian)廠(chang)這類復雜(za)電(dian)磁環境(jing)條件下，衛星授(shou)時(shi)信號易(yi)受阻擋、干擾，進而導致電(dian)廠(chang)內(nei)時(shi)鐘(zhong)同步(bu)體系的(de)紊(wen)亂，影響系統的(de)精準運作。

2、現有的(de)技術路線多是通過(guo)(guo)部(bu)署多套衛星授時(shi)裝置作為(wei)冗余(yu)(yu)配置，以降低(di)衛星授時(shi)信號(hao)中斷的(de)概(gai)率。然而(er)，由于存在過(guo)(guo)多的(de)冗余(yu)(yu)資源，增加了(le)(le)系統維護(hu)的(de)復(fu)雜(za)度(du)和運營成本，限制了(le)(le)其廣泛適用(yong)性。此(ci)外(wai)，即(ji)使增設了(le)(le)多路冗余(yu)(yu)資源作為(wei)備份，但(dan)是這些裝置同(tong)樣暴露于發電廠復(fu)雜(za)的(de)電磁背景(jing)中，仍舊面(mian)臨著被相同(tong)環境因素影(ying)響的(de)風險。

技術實現思路

1、本(ben)發(fa)明的(de)目的(de)是(shi)提(ti)供一種適用于電廠數字化控制(zhi)系統的(de)高可(ke)(ke)靠(kao)(kao)(kao)時(shi)(shi)鐘(zhong)(zhong)授(shou)(shou)時(shi)(shi)系統，通(tong)過架構優化后的(de)時(shi)(shi)鐘(zhong)(zhong)授(shou)(shou)時(shi)(shi)系統的(de)可(ke)(ke)靠(kao)(kao)(kao)性(xing)大幅提(ti)升，使(shi)得系統同(tong)時(shi)(shi)具(ju)備避免(mian)衛星(xing)授(shou)(shou)時(shi)(shi)信號(hao)丟失、錯誤的(de)影響，溯源到標準時(shi)(shi)間，獨立自(zi)主守時(shi)(shi)，自(zi)動和(he)人工切換，適配(pei)不同(tong)用戶的(de)能力，有效滿(man)足(zu)電廠時(shi)(shi)鐘(zhong)(zhong)系統的(de)可(ke)(ke)靠(kao)(kao)(kao)性(xing)、健(jian)壯性(xing)、可(ke)(ke)用性(xing)、準確性(xing)、安全性(xing)等(deng)需求(qiu)。

2、本發明的技術方案如下：一種適用于(yu)電(dian)廠數字化(hua)控制系統(tong)的高可靠時(shi)鐘授時(shi)系統(tong)，包括：衛星授時(shi)分(fen)系統(tong)、時(shi)間溯(su)源分(fen)系統(tong)、自主守時(shi)分(fen)系統(tong)、時(shi)間服務分(fen)系統(tong)以及(ji)監控管理分(fen)系統(tong)；

技術總結
本發明屬于電廠時間同步網絡技術領域，具體涉及一種適用于電廠數字化控制系統的高可靠時鐘授時系統。衛星授時分系統用于接收標準的衛星授時信號，輸出同步后的時間給時間服務分系統；時間溯源分系統接收來自不同授時系統的標準時間，將接收到的標準時間傳送到遠端，并與自主守時分系統的時間進行比對，測量出自主守時分系統時間相對于標準時間的偏差，將偏差輸出給監控管理分系統；時間服務分系統接收衛星授時分系統和自主守時分系統的時間信息，進行質量評估，并將評估結果傳給監控管理分系統，根據監控管理分系統的控制信息或自身對輸入時鐘質量評估的結果，選擇輸入的時間信息，并轉化為用戶需要的時間信息格式輸出。有益效果在于：系統同時具備避免衛星授時信號丟失、錯誤的影響，溯源到標準時間，獨立自主守時，自動和人工切換，適配不同用戶的能力。
