智能变电站系统组态中虚端子存在的问题及改进

Problems and Improvement of Virtual Terminator in Intelligent Substation Configuration

通过对虚端子在智能变电站系统组态配置中存在问题的分析,指出虚端子标准化对提高虚端子连线的准确度,减少智能变电站系统组态配置和现场调试时间都具有重要意义。提出相应规范外部、内部信号和实现虚端子标准化的建议,并给出了一个虚端子描述的改进实例。

By analyzing problems of virtual Terminator in intelligent substation configuration, the paper indi-cates that virtual terminator standardization is key to improve accuracy of virtual terminator wiring and reduce time of intelligent substation configuration and field commissioning. The paper proposes advice on standardiz-ing external and internal signal as well as virtual terminator standardization; moreover, it gives an improve-ment example of virtual terminator description.
