چکیده
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.

Time synchronization of a Commercial Seismometer through IEEE-1588
Seismometers use a GPS signal for time synchronization and the seismic data are collected, time marked and stored. The precision of the time marks is a key parameter for the location and magnitude of an earthquake.Land seismometers are implemented with an internal GPS receiver where only an external antenna is needed for time synchronization. This paper presents the implementation of the time s...
متن کاملPacket Delay Estimation Algorithm Against FIFO Waiting For Asymmetric IEEE 1588 System
Performance in IEEE 1588 synchronization depends on several related factors. Among them, the symmetry of packet delay is the most basic one. But most existing networks could not provide symmetry packet delay between master and slave clocks. From research we found that, FIFO waiting during packet transmitting is one of the main reasons that lead the asymmetry. This paper puts forward a packet de...
