摘要:
实时相量测量一直以来都是电力系统实现动态监测、保护及控制的难点，利用GPS技术的时钟信号的定时精度小于1μs，为DSP芯片TMS320LF2406A的电力系统相量测量建立相同的参考基准，对相应的实验数据进行分析，其测量精度较高、准确性较好，为电力系统快速的在线动态监控提供了重要依据，具有较好的应用价值。

Abstract:
The real-time measurement of phasor is a difficulty in power system dynamic monitoring, protecting and controlling. This paper uses GPS which can provide the clock signal times accuracy of less 1μs, to establish the same reference for measured TMS320LF2406A embedded DSP chip. The analyzed experimental data improves better precision and veracity. It is a significant evidence for the power systems in rapid, on-line and dynamic monitoring-controlling, and is valuable for practical use.
Key words:  GPS  embedded DSP chip  discrete Fourier transform algorithm  real-time phasor measurement
