变电站二次仿真回路虚拟测量系统的实现

Realization of Virtual Measurement System of Substation Secondary Simulation Circuit

变电站二次回路仿真系统通过逼真的虚拟现实实训环境,能有效提高变电运行检修技能培训效果,在实训过程中必须用到虚拟测量工具,因此,研究变电站二次仿真回路虚拟测量系统的结构与技术实现非常必要。以虚拟数字式万用表为例建模,模型中增加了仪表使用错误时智能告警功能,可指出实训人员错误,又不损坏仪表,节省实训成本;同时,提出基于通讯中间件的虚拟测量与变电站二次回路仿真系统的交互模型,能满足多台虚拟仪表同时在培训场景中使用,从而完成对二次回路的状态测量、故障消缺等。在实际二次回路检修技能实操培训中应用时,逼真的虚拟仪表仿真环境沉浸感强,在实操训练中体现了优势,取得了良好的培训效果。

Based on a vivid simulation training environment, substation secondary simulation circuit system can improve the training effect for the operation and maintenance of the substation. During practical training, some virtual measurement instruments have to be used, so discussing the structure and technology implementation of virtual measurement system of substation secondary simulation circuit is necessary. Virtual digital multimeter is taken as an example. Meanwhile, intelligent warning function is available which can point out the errors people make when they use the virtual measurement instruments. This function also can cause less damage to the instruments and save money. Meanwhile, communication middleware is designed to make the communication between virtual measurement system and substation secondary simulation circuit system. And, many virtual measurement instruments can be used at the same time so measuring and correcting in substation secondary simulation circuit are achieved. A vivid simulation training environment is implemented when virtual measurement instruments are used it can be a big advantage and the result of the training is fairly satisfactory.
