同步相量测量装置的一种异地校核方法

提出利用对晶振信号进行整数分频并结合GPS同步时钟生成相量测量装置(PMU)异地同步校核中基准信号的方法。通过分析可知，只要晶振频率足够高，生成的基准信号就有足够高的精度，而且信号的参量具有良好的可调节性。该方法可有效解决PMU测量网络中异地同步校核和自校核问题。

A GLOBAL CHECKING METHOD OF SYNCHRONIZED PHASOR MEASUREMENT UNIT(PMU)

This paper proposes a method based on the integral de-multiplication technique and GPS synchronized clock to generate the global synchronized checking reference signal of PMU. Analysis result shows that the reference signal can be highly precise and provide an adjustable performance if the given frequency of crystal is high enough. This method can effectively solve the problem of global synchronized checking and self-checking of PMU precision in synchronized measurement network.
