摘要
在电力系统中,采样数据的同步性越来越受关注,现代网络技术的发展为数据的传输提供了极大的方便,同时数字信号处理器(DSP)的发展为数据采集系统提供了强有力的硬件基础。文章给出了基于DSP的数据采集系统,采用全球定位系统(GPS)授时技术对系统进行同步处理,处理后的数据通过TCP/IP网络协议转换模块传到Internet上。由于数据被打上了时间标签,为数据的再处理、分析等提供了便利条件,为电力系统的广域测量提供了保障。
In power systems, the synchronization of sampled data is paid more attention, and data transmission is very convenient along with the development of network technology, At the same time digital signal processor （DSP） offers strong hardware foundation for data acquisition system. The paper gives a data acquisition system using DSP and GPS, where GPS is used to the clock synchronization of system, and the disposed data are transmitted to Internet by TCP/IP network protocol conversion module, Because the data are marked on time label, it gives a great of convenience on data analysis and aftertreatment, and it gives ensuring for wide area measurement in power system,
