Server-side simulating system based on IEC61850 and method thereof

Abstract

The invention provides a server-side simulating system based on an IEC61850 and a method thereof, which are applied to digital substations adopting the IEC61850 for communication and traditional substations. The system consists of a simulator terminal and a simulator console. The method comprises the following steps: loading an SCD model at the simulator terminal for analyzing; breaking out a CID model file needed by an IED; carrying out man-machine interaction in a tree diagram and tabular form to allocate one data generator for each module data; generating state sequence through the data generator; downloading the state sequence to the simulator control table; loading the CID model broken out by the simulator terminal on the simulator console for analyzing; establishing an IEC61850 database, organizing the trackback path information of the IEC61850 model orderly; addressing the IEC61850 database according to the model trackback path corresponding the data generator; refreshing the IEC61850 database state in real time; and interactively communicating with a station monitor and control layer through the IEC61850, thereby finishing the simulation of the IED server terminal. The invention can carry out simulating preview on the whole substation IED, greatly saves project debugging time and has the characteristics of strong operability, high efficiency, flexible configuration and the like.

Description

technical field [0001] The invention relates to IED (Intelligent Electronic Devices, hereinafter referred to as IED) server-side simulation technology for digital substations and traditional substations using IEC61850 communication. Data and generate a state sequence, and directly address the implementation method of the IEC61850 database through the model reference path. Background technique [0002] The International Electrotechnical Commission TC57 formulated the IEC61850 communication standard on the basis of summarizing the previous communication protocols. The communication standard unifies the modeling of the objects in the substation automation system, adopts object-oriented technology and the abstract communication service interface (ACSI) independent of the network structure, enhances the interoperability between devices, and can be used between devices of different manufacturers seamless connection between. This standard has the characteristics of flexible confi...
