摘要
介绍了用于研究电力系统动态等值在线测辨问题的测量装置,并对数据采集中共享存储器的实现方法进行了分析。该测量装置的核心是自带CPU和共享存储器的数据采集卡,插于工控机ISA扩展槽,数据采集卡通过共享存储器与工控系统机共享数据,大大提高了数据采集速度和数据缓冲容量。该装置经现场运行,效果良好。
The hardware and software of data acquisition system for power system on-line identification are introduced,and the technique using sharing-RAM in data acquisition system is analyzed.This data acquisition system is based on a data acquisition card with its own CPU and sharing-RAM,which will be set in ISA-bus of industrial control computer.Through the sharing-RAM,the acquired data are shared by data acquisition card and industrial control computer,in this way the acquisition speed and the volume of data buffer are highly improved.The practical operation result shows that the proposed system is satisfactory.
