典型110kV智能变电站一次电气系统设计

Primary Electrical System Design of Typical 110kV Intelligent Substation

智能变电站功能定位在于通过先进的信息、控制技术,提升变电站作为电网基础运行单元的智能化水平,实现作为电网枢纽的变电站的智能化管理,为建设智能电网打下坚实的基础。随着电力市场改革、优化营商环境、电网精益化管理等一系列政策的影响下,智能变电站是常规变电站的发展方向。本文以典型110 kV智能变电站为例,详细介绍了其一次电气系统设计及其关键技术。

The function orientation of Smart Substation is to improve the intelligent level of substation as the basic operation unit of power grid through advanced information and control technology,realize the intelligent management of substation as the hub of power grid,and lay a solid foundation for the construction of smart grid.With the influence of a series of policies,such as power market reform,optimization of business environment,power grid lean management,smart substation is the development direction of conventional substation.Taking a typical 110 kV intelligent substation as an example,this paper introduces the design of its primary electrical system and its key technologies in detail.
