一种模型驱动的测控装置优化研究

摘要

Now, the configuration files of the measurement & control devices are not uniform and perfect, resulting that the measurement & control devices are not all dependent on IEC 61850 models. On account of those questions, this paper proposes a design method of MDA device. By extending Substation Specification Description (SSD)in Substation Configuration Description (SCD)model file, the SSD file describes primary circuit wiring diagram of substation, and makes relevancy with signals from secondary devices. It also configures all the mis-operation rules based on SSD file. The method makes the model file include five elements such as communication connections, network communication parameters, function configuration parameters, mis-operation rules and primary equipment wiring diagram with format of Scalable Vector Graphics (SVG). It will achieve the goal that measurement & control device is driven by models completely, what will eliminate the risks of configuration files tempered and be easy to operated and maintained.%目前, 测控装置配置文件不统一, 配置信息不完善, 并未实现完全由IEC 61850模型驱动.针对以上问题, 提出一种模型驱动的测控装置设计方法.通过在变电站全站配置描述文件 (SCD)中扩展系统规范模型 (SSD), 由SSD表述全站一次设备拓扑且完成与二次设备信号的关联.基于SSD配置全站五防闭锁逻辑关系, 使模型文件包含通信连接关系、网络通信参数、功能配置参数、五防闭锁逻辑规则、可缩放矢量图形 (SVG)格式的一次接线拓扑等几方面信息, 统一完成测控装置的全部配置, 消除配置文件被篡改的风险, 便于后期运行维护.
