在電力系統(tǒng)的運(yùn)用中，時(shí)間同步是一種zui基本的應(yīng)用，也在不斷的更新技術(shù)以及工藝。但是在GPS和北斗衛(wèi)星授時(shí)系統(tǒng)中，由于設(shè)備的品牌不同，這就使得站內(nèi)、站與站之間的時(shí)間不能統(tǒng)一。在運(yùn)行的過程中，時(shí)間接受系統(tǒng)之間不能相互通用，這就會造成內(nèi)部之間的運(yùn)行不能準(zhǔn)確備份，難以保障整個(gè)系統(tǒng)運(yùn)行的可靠性。因此電力系統(tǒng)的設(shè)備更新要逐漸擴(kuò)展到發(fā)電廠、變電站控制中心、調(diào)度中心等，加強(qiáng)時(shí)間同步技術(shù)，并且要基于不同的授時(shí)源建立時(shí)間同步，而且要互為熱備用。
