“…In [17] authors illustrate the influence of time synchronization error (TSE) on the modal analysis and damage detection and concluded that TSE has a strong impression on the mode shape detection, damage localization, and damage discovery. [18] analyses the effect of clock synchronization loss on the synchro phasors-bases applications. Experimental evaluations demonstrate that a phase angle monitoring system expresses an erroneous power system state and operating time of an anti-islanding protection application also gets disturbed due to loss of timesynchronization signal input to PMUs.…”

Precise time synchronization becomes a vital constituent due to the rigorous needs of several time-sensitive applications. The clock synchronization protocol is one of the fundamental factors that can define the quality of communication. Our study starts with a brief discussion on the application domain of precise time synchronization and comes with an in-depth study of the synchronization with the main focus on the IEEE 1588 Precision Time Protocol (PTP). We have compared the well-known synchronization techniques and conclude that the PTP is the most appropriate answer to robust clock synchronization though challenges are there that requires thoughtful efforts and modification in the current version. The working mechanism and main components of the PTP network are discussed. We have established a testbench using commercially available devices and development boards to evaluate the PTP performance under different configurations. Major sources of synchronization error and other aspects contributing to precision are examined. This paper discussed numerous approaches that could enhance the performance of the PTP protocol. Structures for PTP based wireless clock synchronization required by advanced applications has also been discussed. In the end, paper focuses on the main industrial application areas in which PTP plays an important role, including WLAN, optical data centers, Smart grid, IEC 61850, etc. We conclude the paper by identifying the future trends and research directions for PTP based clock synchronization.

“…The loss of time synchronization signal due to intentional interference can be considered as a jamming attack on the physical layer (GPS receiver) [28]. In order to investigate the impact of loss of time synchronization signals (GPS / IRIG-B) on synchrophasor-computation by PMUs from different vendors, RT-HIL simulation was carried out by utilizing PMUs from 4 different vendors.…”

This paper experimentally assesses the impact of time synchronization spoofing attacks (TSSA) on synchrophasorbased Wide-Area Monitoring, Protection and Control applications. Phase Angle Monitoring (PAM), anti-islanding protection and power oscillation damping applications are investigated. TSSA are created using a real-time IRIG-B signal generator and power system models are executed using a realtime simulator with commercial phasor measurement units (PMUs) coupled to them as hardware-in-the-loop. Because PMUs utilize time synchronization signals to compute synchrophasors, an error in the PMUs' time input introduces a proportional phase error in the voltage or current phase measurements provided by the PMU. The experiments conclude that a phase angle monitoring application will show erroneous power transfers, whereas the anti-islanding protection mal-operates and the damping controller introduces negative damping in the system as a result of the time synchronization error incurred in the PMUs due to TSSA. The proposed test-bench and TSSA approach can be used to investigate the impact of TSSA on any WAMPAC application and to determine the time synchronization error threshold that can be tolerated by these WAMPAC applications.
