IEC 61850在智能变电站应用时采用网络结构分析

Analysis on Network Configuration Based on the Application of IEC 61850 in Smart Substations

不同的网络结构提供不同的网络性能,通过一些网络交换设备在一定程度上可以达到成本和冗余方面的预期。随着智能变电站的建设,网络在智能变电站中的地位越来越重要。文章从IEC 61850在变电站的站控层应用的角度,对网络结构进行了分析,对不同网络结构的优缺点进行了比较,理清了网络系统可靠性与网络结构之间的关系,对于建设高效、可靠的系统具有重要意义。

Different network architecture provides different network performance. By adding some network switch equipment, the expected target on both cost and redundancy can be reached. With the construction of the smart substations, network plays an even more important role. Based on the application of IEC 61850 at the control layer of substations, this article analyses the network architecture, and compares the advantages and disadvantages, and discusses the relationship between the system reliability and the network architecture. It has reference value for the construction of a efficient and reliable system.
