摘要
智能变电站的建设,推动了交换机技术和网络通信技术的发展。文章从数据报文交换、协议功能及硬件需求3个方面深入阐述了智能变电站对交换机技术的需求,提出了一种能够适用于智能变电站的高速数据通信交换装置研制方案,详细介绍了其软、硬件的设计架构及各软件模块的作用。与原有技术相比,新的高速数据通信交换装置简化了硬件设计方案,提高了网络吞吐能力,减少了报文驻留延迟,实现了SV报文延迟测量功能,为研制第三代智能变电站专用交换机提供了一个切实可行的解决方案。
The development of smart substation has promoted the development of switch technology and network communication technology. This paper presents the requirements of the smart substation to switch technology from three aspects： data packet switching, protocol function and hardware requirements. Then, a design scheme of high speed data communication switching device suit for smart substation is proposed, and its hardware design, software architecture and the function of each software module is introduced in detail. Compared with the original technology, it simplifies the hardware design scheme, improves the network throughput, reduces the delay of the packets, realizes the SV packet delay measurement, and provides a feasible development plan for the realization of the third generation switch of smart substation.
