在智能变电站环境下,自动调谐消弧线圈面临新的发展要求。结合IEC 61850标准的特征、智能变电站的通信特点和自动调谐消弧线圈的特殊功能,提出了应用于智能变电站的自动调谐消弧线圈的2种实现方案：一种方案是一次设备和二次设备集中布置,实现控制器的就地控制;另一种方案是一次设备和二次设备分散布置,控制器分为主控单元和智能测控单元2个部分,实现控制器的远程控制。分析了这2种设计方案的优缺点,提出在35kV以下智能变电站中应优先采用集中式结构的消弧线圈,该方案结构简单、成本低,技术经济性更好。

In order to better fit the development of smart substations,the auto-tuning arc-suppression coil（AAC） faces new development requirements.Two design schemes of AAC for smart substations are proposed,in consideration of the features of IEC 61850 protocol,communicational features of smart substation and special functions of AAC.First,local-control scheme is implemented with concentration layout between primary equipment and secondary equipment;Second,remote-control scheme is implemented with primary equipment and secondary equipment arranged distributively,where the controller is divided into main control unit and intelligent measurement/control unit.After deep analysis of advantages and disadvantages of the two designed schemes,the local-control scheme of AAC should be given priority for smart substation below 35 kV,as it enjoys simpler structure,lower cost and better technical economy indices.
