智能变电站部分二次虚端子典型设计问题分析

Analysis on Typical Design on Secondary Virtual Terminals in Intelligent Substation

针对智能变电站中二次虚端子的作用与功能发生变化而导致原来规变电站某些已经形成规范设计的二次回路未能规范设计思路的问题,进行深入的分析,评价各类设计思路的优劣性,给出具有规范典型设计思路的建议,表明智能站中二次虚端子设计需要整体把握原则与方向,目的在于提高智能变电站的可靠设计和运行。

In allusion to the problem that some original normatively designed secondary circuits in those conventional substa- tions can not form standard and unified design thought due to changing of effect and function of secondary virtual terminals in the intelligent substation, this paper analyzes and evaluates advantages and disadvantages of various design thoughts, pro- vides suggestions about normative typical design thought and points out principles and direction for designing secondary virtu- al terminals in intelligent substations so as to improve reliable design and operation of intelligent substations.
