The Design and Implementation of Substation Graphic Gateway System Based on IEC61850 Technology

As the application of IEC61850, the condition monitoring systems and auxiliary systems have been used in substation, and the amount of substation data becomes more and more large. In order to solve the management problems generated by large amounts of substation data, the National Dispatching Center has proposed the Direct alarm and Remote browsing techniques based on traditional remote communication device. This paper uses an embedded platform graphic gateway and uses IEC61850 to get real-time data and graphics of substation. It sends the data to D5000 system of dispatch center via DL/476, and the real-time data transmission and monitoring data refresh have reached the requirements of engineering applications and achieved good applied effect.
