Sažetak
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.
