摘要
智能变电站技术仍处于发展阶段,但它是变电站建设的必然趋势。目前,中国智能变电站数量较少,实际运行管理经验较常规变电站欠缺。由于智能变电站自身的特点,给运行值班人员的学习理解带来一定困难。过程层网络是智能变电站的重要基础,直接关系到全站数据采集和开关控制的可靠性和实时性。以新建220 kV彩虹智能变电站为例,介绍了智能变电站保护、测控、智能组件配置,分析了各典型间隔保护、测控、智能组件之间的网络连接及信息传递。对彩虹智能变电站的网络剖析可以给运行值班人员对智能变电站设备的运行操作提供一定参考。
The study of smart substation is in progress, but it is an inevitable trend to the further development of substation constructions. The quantity of smart substations is still low at present in China, and it is lack of the experiences in operation and management of smart substations, so operators also face many challenges in study and understanding. Process layer net-working is an important base of smart substation. The composition, information transmission and network connections of process layer networking are introduced taking 220 kV Caihong smart substation for example. Network analysis of this smart substation provides a reference for operation and manipulation of smart substation.
