摘要
本文对电力系统自动化装置时钟统一的要求与现状做了分析和阐述,对于GPS在时钟统一问题上的应用做了可行性研究。结合WGX电网故障信息处理系统研制中时钟统一的具体实现,本文介绍了GPS信号用于电网微机保护装置时钟校准的应用设计,目前这一应用已开始投入现场运行,效果良好。
The requirement and current state of clock synchronism of automatic devices in power system are analyzed and described,and a feasibility study is made on the application of GPS in clock synchronism.Linking with the concrete realization of clock synchronism in the development of WGX electric network fault information processing system,this paper introduces how GPS signals are used in clock calibration of microcomputer-based protective devices in power network.Now this application has been used on site with good result.It is geting more and more interests from power operational departments.
