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.
