摘要:

針對傳統的時(shí)鐘同步方法已經(jīng)無(wú)法適應新一代電力系統對時(shí)鐘同步提出的更高要求,引入了一種能達到亞微秒級同步精度的1588v2時(shí)間同步技術(shù),可以完全滿(mǎn)足新一代電力系統中數字化變電站等電力二次終端設備高精度時(shí)間同步的要求;在對OTN和PTN進(jìn)行同步技術(shù)分析的基礎上,提出了基于OTN+PTN統一同步網(wǎng)絡(luò )組網(wǎng)模型的應用場(chǎng)景,探討了1588v2時(shí)鐘信號在混合網(wǎng)絡(luò )中的傳遞方式,并在現網(wǎng)中進(jìn)行了時(shí)間同步性能測試驗證,時(shí)間精度優(yōu)于±100 ns;研究結果表明,基于1588v2時(shí)間同步技術(shù)的OTN+PTN組網(wǎng)模型能夠滿(mǎn)足電力系統業(yè)務(wù)的同步需求。

Abstract:

As the traditional clock synchronization technique has been unable to meet higher requirements of clock synchronization in new generation of power system, this paper introduces a method of 1588v2 time synchronization technology,which could reach sub-microsecond level of synchronization accuracy and completely meet the requirements of higher time synchronization precision proposed by power two terminal equipments such as digital substation in new generation of power system. Based on Synchronization Technology Analysis of OTN and PTN, it puts forward the application of the unified synchronous network model based on OTN and PTN,discusses the transmission mode of 1588v2 clock signal in the hybrid network, tests and verifies the synchronization performance of the existing network,time accuracy is better than ±100 ns. The research results show that OTN and PTN network model based on 1588v2 time synchronization technology can satisfy the synchronization requirements of power system operation.
