摘要
Abstract
As a high-precision time synchronization technology for distributed network, IEEE 1588 is very important for the construction of smart substations. Firstly, the principle of time synchronization of IEEE 1588, which gives the time synchronization process and the synchronization compensation algorithms of two link delay measurement mechanisms, is presented; then the time-related measurable contents during the synchronization of intelligent components, including the time synchronization accuracy of precision time protocol （PTP） utilizing intelligent components as master clock or slave clock, the sampling uniformity and output time of sampled value （SV） message and the response time and output time of generic object oriented substation event （GOOSE） message, are proposed; finally, the time-related parameters for the main transformer protection and monitoring intelligence component of UDT-531 are tested and analyzed. The results show that the measured time parameters of UDT-531 could basically meet the needs of IEC 61850 standard, thus the feasibility of the proposed time measurement approach is verified.关键词
