| Summary: | 碩士 === 國立臺北科技大學 === 自動化科技研究所 === 105 === The development of smart grid industries has grown rapidly in the past decades. During the operation of power system, accurate time synchronization is essential to ensure that the normal operation of the power system. When a failure occurs, recording the event with accurate timestamp is important for further analysis. Time synchronization system can be used to synchronize the time between various devices, so that the time among different devices can be synchronized.
A common time synchronous technology used in the power system is IRIG-B. The time synchronous technology relies on the signal received by GPS receivers. The synchronized timestamp is applied during an occurrence of an event in power system. A PPS signal can be generated from the synchronized system. The PPS signal can be used for synchronous phasor measurement technology.
Wireshark is used to capture packets in order to verify correctness of the time synchronous packets between different devices. The PPS signal generated from the synchronized clock is also used to generate an accurately frequency synchronous sampling.
