一种同频异步核相检测方法及其应用

Single Frequency and Asynchronous Phase Sequence Detection Method and Its Application

在分析国内传统核相试验方法存在不足的基础上,提出了一种基于同步基准相位偏移量的同频异步核相检测方法。分析了同频异步核相检测方法的工作原理及实现方法,该方法基本消除了干扰对核相结果的影响。试制出的同频异步核相装置,在上海市电力公司浦东供电公司的应用,验证了该技术可以实现对相同或不同电压等级的电源之间的异步核相。

A new single frequency and asynchronous phase sequence detection method applied in power systems is proposed due to the lack of study on analytic traditional phase detection method in our country. The principle and realization of the new method are presented, the results of the new method prove the signals will not be affected by the changing frequency in the power system. The single frequency and asynchronous phase sequence detection device applied in Pudong Power Supply Company of SMEPC, is tested that the method succeeds in asynchronous phase sequence detection for the same or different voltage levels.
