摘要
为解决智能变电站数字化装置采样大容量问题,提出一种通用、可配置、高性能装置类平台。此平台采用外设组件互连标准扩展(PCIe)高速总线作为专用采样通道,解决采样瓶颈问题,同时融合直接内存操作(DMA)、低压差分信号(LVDS)等关键技术,提升了整体数据交换能力。实际工程应用表明,该平台能够解决采样大容量及实时数据交换问题,并且使用更方便,应用更广泛,取得了良好的效果。
A generic, configurable and high-performance device platform is developed for large capacity sampling of the smart substation digital device. This platform solves the sampling bottleneck problem by using PCIe bus as a special sampling channel, and greatly enhance the overall data exchange capability through the key technology of DMA and LVDS. Engineering application shows that the platform is effective and convenient in large capacity sampling and real-time data exchange.
