Abstract-Clock synchronization is a prerequisite for the realization of emerging applications in various domains such as industrial automation and the intelligent power grid. This paper surveys the standardized protocols and technologies for providing synchronization of devices connected by packet-switched networks. A review of synchronization impairments and the stateof-the-art mechanisms to improve the synchronization accuracy is then presented. Providing microsecond to sub-microsecond synchronization accuracy under the presence of asymmetric delays in a cost-effective manner is a challenging problem, and still an open issue in many application scenarios. Further, security is of significant importance for systems where timing is critical. The security threats and solutions to protect exchanged synchronization messages are also discussed.

“…Song and Kang Lee published an application framework for the PTP standard, the purpose of this paper was to provide a prototype application system. [5] In recent years, the study of PTP Stack has been branched out into different projects in the Open Source Community, the Linux PTP project was one of them. The Linux PTP Project support both software and hardware timestamping, the Linux kernel version 3.0 or newer is required, the subsystem of the PTP Hardware Clock (PHC) driver framework and userspace Application Programming Interfaces (API) was merged into the Linux kernel since version 3.0, the kernel of most of Linux distribution have the need for upgrade.…”

“…We have to resort to a newer and more precious synchronization method and system. IEEE1588 is known as the Precision Time Protocol (PTP), it has been adopted by International Electromagnetic Committee (IEC) as IEC61588 standard, been developed with the following aims [2,3,4]: a. To enable system-wide synchronization of clocks in sub-microsecond range in measurement and control systems implemented with current advanced technologies, its' synchronization algorithm is shown in fig.…”

By reviewing the application status of traditional clock synchronization methods and architectures under different protocols in a comparative way in China, this paper analyzes the application of IEEE1588 protocol in power dispatching automation and puts forward new clock synchronizing schemes in electricity dispatching communication network based on IEEE1588 protocol (or Std. IEC61588) and proposes some futuristic research fields referring to IEEE1588 protocol in power dispatching automation. New schemes have better clock synchronizing precision, featuring in low implementation cost compared with other clock synchronization schemes. At the same time, it will effectively lower system resource requirements, relieve current excessive reliance on GPS clock source, mitigate data fetching and exchange congestion. It will shed light on building domestic power dispatching networks under the PTP protocol as well as constructing smarter power grid both at home and abroad in the future. This work is supported by North China Electric Power University, Sifang & Huaneng Power System Control Co., Ltd and Zhuhai Power Electricity Supply Company in SMART SYNCHRONOUS DEVICE RESEARCH BASED ON IEC61850 AND IEEE 1588 project, which involves a wholesale research in clock synchronization of power dispatching communication networks and developed China’s first set of smart clock synchronization devices, including the clock synchronization handler CSE6000 (briefly introduced in part v) and corresponding kilomega Ethernet switch. Our research results have reached the advanced level at home, and we are applying for a patent protection accordingly.
