为了真实的实时监测电网状态，越来越多的基于全球定位系统（GPS）的相量测量单元（PMU）被部署在电力系统中。然而，当某些不可控和不可预测的因素出现时，PMU内部的GPS接收机往往会失去信号锁定。为了解决这个问题，芯片级原子钟（CSAC）被提出来作为备份解决方案的时间同步本文。这是首次报道CSAC在电网中的应用。测试结果表明，CSAC可以作为GPS定时的可靠和准确的备份。
Global Positioning System (GPS)-based phasor measurement units (PMUs) are increasingly deployed in the power system in order to monitor the grid status in real time. Nevertheless, GPS receivers inside PMUs tend to lose signal lock when certain uncontrollable and unpredictable factors arise. To address this issue, chip scale atomic clock (CSAC) is proposed to be used as a backup solution for time synchronization in this paper. It is the first time ever reporting the utilization of CSAC in the electric power grid. Test results show that CSAC can work as a reliable and accurate backup for GPS timing.
