Summary/Abstract: With the emergence of Smart Grid technologies, the wide area measurement systems show potential in securing the reliability of the power grids by using real-time centralized data collection over hundreds or thousands of kilometers. The strict requirements for sub-20 ms one-way delay of these systems impose numerous challenges to the process of accurate network delay measurement. In this paper, a test bed for one-way delay measurement in wide area measurement systems is proposed. The test bed is based on system clock synchronization to the Coordinated Universal Time (UTC) via Global Positioning System(GPS) receivers and Network Time Protocol (NTP) servers. In order to evaluate and bound the measurement error, two experiments have been performed in accordance with the IETF RFC 2679 standard. The results show low relative errors and allow accurate reporting of the one-way delay measurements.
