智能变电站交换机选型

Ethernet switch selection in smart substation

国内智能变电站当前进入全面建设阶段。以太网作为智能变电站的基本通信网络可看作是全站的神经中枢,以太网交换机的作用凸显,成为智能变电站的关键性部件,它的性能直接影响到变电站、乃至智能电网运行的可靠性。结合智能变电站的特点分析了智能变电站交换机的应用需求,介绍了为实现上述应用所需交换机的技术性能,从可靠性、实时性、时钟同步模式、组播管理能力、安全性等方面阐述了选型要求,为提高智能变电站自动化系统的可靠性提供意见和参考。

Smart substation has entered fully construction phase in China. As the basic communication network, Ethernet is the nerve center of smart substation. Ethernet switch, whose performance directly affects the reliability of smart substation and smart grid, becomes the key component in the smart substation. Combined with the features of smart substation, the applying requirements and technology of smart substation Ethernet switch were analyzed. The requirement was clarified from different aspects such as reliability, real-time, clock synchronous mode, multicast management ability and security, which provides references for improving the reliability of smart substation automation system.
