摘　　要：GPS授时以其精度高、所受干扰小、实时等优点而在授时工作上有着广泛的应用前景。本文研究了具有定时功能的GPS-OEM芯片RS232输出和1PPS输出的特点及应用,并提供了在电力系统功角广域测量中用其实现精确授时的方法,可用于改进传统的授时模式。GPS timing has the merits of high precision, antidisturbance, around-the-clock broadcasting and so on. So it will be widely used in timing. This paper makes research on the characteristics of GPS-OEM chip for timing and provides the methods of how to use it realizing timing in wide area powerangle measurement system in power system. These can be used in improving the conventional mode of timing.
