“…Note that most of the functionalities listed in Table IV cover the areas of the power grid up to the substation. One significant modification to the grid with a stringent synchronization requirement is the wide area monitoring system (WAMS), supporting the use of synchrophasor measurements of timestamped harmonic power components for real time grid control [38], [39], [41], [42].…”

“…With an increasing number of Intelligent Electrical Devices (IEDs) (e.g., voltage regulators, protective relays, recloser controllers, various sensors, etc.) to smarten power grids, there is an increasing interest to distribute synchronized time in a cost-effective manner, for example by using PTP [39]. Equipping each IED with a dedicated GNSS module would be economically impractical [42].…”

“…NIST recently designed a testbed to verify the synchronization performance capabilities of PTP for power distribution applications, as depicted in Fig. 9 [39]. In this testbed, the ordinary clocks (OCs) synchronize with the grandmasters (GMs) interconnected via boundary or transparent clocks (BCs/TCs) with PTP hardware support.…”

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.

“…The conformance testing of ordinary clocks which realizes major common protocol functions was discussed in [11]. In [12], an IEEE 1588 testbed was established to check the character of the system and verify its devices accuracy. In order to evaluate the influence of synchronization accuracy caused by environmental temperature change and network load increased, the external factors influencing the synchronization system were tested by reproducible method in [13].…”

Original scientific paper As a synchronization method, IEEE1588 standard has been applied in substation, it should be tested and verified ensure synchronization accuracy and node interoperability. A comprehensive testing method for the IEEE1588 is proposed in this paper. Furthermore, IEEE1588 clock testing platform is built to support the proposed testing method. Based on the analysis of the clock synchronization error and the performance testing principle method, the accuracy and stability of master clock and slave clock were evaluated. Secondly, the conformance testing to adopt performance response was achieved by designed specific case, based on the above, and then to analyse the conformance implementation details. According to testing requirements, test bed designed. Finally, the experiment based on substation devices was carried out using the IEEE1588 clock testing platform. The feasibility of the proposed methods was further verified with the testing results.

Metoda sveobuhvatnog testiranja za IEEE1588 se predlaže u ovom radu. Nadalje, IEEE1588 platforma testiranja ure izgrađena je kao podrška predložene metode ispitivanja. Na temelju analize sinkronizacije pogreške ure i metode ispitivanja načela značajke, ocjenjene su točnost i stabilnost glavne ure i pomoćne ure. Drugo, ispitivanje usklađeno s normom za usvajanje odziva značajke je postignuto dizajniranjem konkretnog slučaju, na osnovi navedenog, a potom analizirati pojedinosti provedbe sukladnosti. Prema zahtjevima ispitivanja, dizajnirana je testna osnovna ploča. Konačno, pokus utemeljen na uređajima transfostanice proveden je uporabom IEEE1588 platforme testiranja ure. Izvedivost predloženih metoda dodatno je potvrđena s rezultatima testiranja.
