摘要
智能变电站是智能电网中变换电压、接受和分配电能、控制电力流向和调整电压的重要电力设施,是智能电网"电力流、信息流、业务流"三流汇集的焦点,变电站智能化对建设坚强智能电网具有极为重要的作用。首先介绍了综合自动化变电站、数字化变电站、智能变电站系统的特点、架构,在此基础上探讨了两种智能变电站系统方案,并对智能变电站系统的关键技术及目前存在的问题进行了分析和探讨。
Smart substation is a important power device on converting to voltage accepting and distributing electric energy control power flow and adjusting voltage in Smart grid, and it is the focus of power flow information flow business flow in Smart grid. So, substation intelligent is very important to construct strong smart grid. First,this paper introduce to the distinguishing feature among integrated automation of substation analyzed,digital substation,smart substation. On this basis ,discussing two kinds of plan,analyzing and researching On the key technology of smart substation and the main problem that exists at present.
