摘要
如何在技术形态和设备形态不同于传统变电站的智能变电站实现消弧线圈的自动调谐控制和小电流接地选线功能是本文探讨的重点。本文从智能变电站建设的要求出发,提出了消弧线圈及接地选线智能化实施方案。该方法借助智能变电站现有架构体系,增加就地智能单元并依靠IEC 61850标准实现智能测量和网络控制,满足消弧线圈和小电流接地选线的智能化要求。实际工程应用验证了该方案的可行性。
The incorporate device of automatic arc-suppression coil and grounding fault line selection is applied widely in medium voltage grid.With the construction of smart substation,it is necessary that all of primary devices in substation are intelligentized.In this paper,the intelligent scheme for incorporate device of automatic arc-suppression coil and grounding fault line selection is researched and discussed primarily.To intelligentize the device of automatic arc-suppression coil,the local intelligent unit and the controller that supports the communication standard of IEC 61850,are adviced to adopt.The three intelligent schemes for the grounding fault line selection are analyzed.Finally,an engineering application instance for the scheme introduced in this article is stated.
