Design And Implementation Software Platform Of Smart Substation For Detection Help

With the rapid development of power grid in the past few years, our country has built a lot of smart substation. Today the scale of Chinese power grid has been ranked the largest all over the world, there is growing urgent to require the application of smart substation automation technology. In order to ensure safe and stable operation of smart substation, substation monitoring and detection is essential. Now under the smart substation standard IEC 61850, the station digital information have proper normativity and interactivity, but the digitized result is different from power relay protection’s original expression, and there are no related software products supporting the detection of smart substation. At the same time for the existing smart substation network architecture is layered, the station is also a lack of integration information integration process monitoring. Based on this view, the thesis center on the information of smart substation relay protection and propose the idea of online information integration process software platform which based online monitoring and supports the application of detection assistance.Different from the traditional way that separated monitoring by divide network, the software platform is designed for getting the whole substation network information at the same time in this paper’s consideration. The platform gets the whole substation packet through a specific hardware interface, in this way GOOSE messages, MMS messages and SV messages are received simultaneously. So it can realize integration usage of all the packet. The thesis designed relay protection template library and detection security measures template library, these two libraries are instantiated to get relay protection example and detection security measures example. It implements on-line processing messages and relay protection events’ graphic displays as well as detection tips and verification on the software platform.The main work of this paper include:1. Study on standard IEC61850 and the SCD file, designed a new type of data structure which integrated SCD file structure and MMS-ACSI structure to obtain substation secondary equipment information model of the SCD file through dynamic parse;2. According to the relay protection example library implements functionality event tag in information model, judge the relay protection event when the parsed packet writing into information model, send the event to the display module and database as well as other modules that need the event;3. Analyze the secondary equipment platen information and summarize the detection security measures, the paper designed detection security measures template library that can get detection security measures by combining SCD information model, detection work realized automatically generation through the principle of searching detection devices;4. Software platform implemented platens’ status monitoring on real-time verification of the detection work, information can be prompt implementation of the detection security measures, and show device group relationship through the graphical display.
