智能变电站二次设备配置方案研究

Intelligent Substation Secondary Equipment Configuration Scheme

按国家电网规划,高电压等级新建变电站项目均按智能化变电站建设实施。而目前投运以及在建的智能化变电站中,主要二次设备配置方案以及设备选型也各不相同。以海北500 kV智能化变电站为工程实例,在网络架构配置、保护跳闸方式、互感器选型、时钟对时以及一次设备在线监测等方面进行了方案比较与研究,为其他智能化变电站的建设提供了参考。

According to the national power grid planning, the project of high voltage level new substation will be built as intelligent substation. As for the current intelligent substations in operation or under construction, the current oper- ation and in the construction of intelligent substation, the main secondary equipment configuration and equipment se- lection are also different. This article takes the Haibei 500 kV intelligent substation for example to compare and study many considerations about the scheme such as the framework of network configuration, protection tripping mode, transformer,clock timing and on line monitoring of primary equipment,which provides a good reference for the con- struction of other intelligent substation.
