本文讨论的同步测量技术有潜力成为实时监控系统的支柱。由于电力需求不断增加、互联数量不断增加、可再生能源的渗透以及能源市场条件的放松管制，现代电力系统的安全可靠运行成为一项越来越具有挑战性的任务。因此，世界各地的电力公司都感受到了对实时广域监测、保护和控制 (WAMPAC) 系统的需求。同步测量技术（SMT）有潜力成为该系统的支柱。使用 SMT 的主要优点是 1) 来自广泛分散位置的测量可以与全球定位系统 (GPS) 时钟同步，2) 可以直接测量电压相位角，这在技术上迄今为止是不可行的，3) 能源管理系统 (EMS) 应用的准确性和速度成倍提高。
This article deals with the synchronized measurement technology that has the potential of becoming the backbone for real-time monitoring system. The secure and reliable operation of modern power systems is an increasingly challenging task due to the ever-increasing demand for electricity, the growing number of interconnections, penetration of variable renewable energy sources, and deregulated energy market conditions. Power companies in different parts of the world are therefore feeling the need for a real-time wide area monitoring, protection, and control (WAMPAC) system. Synchronized measurement technology (SMT) has the potential of becoming the backbone of this system. The major advantages of using SMT are that 1) the measurements from widely dispersed locations can be synchronized with respect to a Global Positioning System (GPS) clock, 2) voltage phase angles can be measured directly, which was so far technically infeasible, and 3) the accuracy and speed of energy management system (EMS) applications increases manifold.
