Title Substation Simulation System Development Based on MATLAB and Configuration Software

Abstract

Substation simulation system is a branch and direction of the digital simulation. It is based on computer software and network technology, and it can simulate the state of the running equipment in substation, with the rigorous calculation made by mathematical model. Therefore, a user-friendly interface can be provided for the training and analysis by it.

Digital simulation with human-machine interface consisting of substation simulation training system can be intuitive, detailed to show the characteristics and the operation of substation, and it is easy for students or workers to learn the knowledge about power system.

In this paper，models have been built in matlab/simulink to finish related simulation， and all these simulation are set as a background service in the substation simulation system; A substation monitoring interface has been designed and built using Kingview, and it is set as a interface in the substation simulation system; DDE is used to exchange data between matlab and Kingview. Main programme and other functions are written to connect interface and background service to consist a stand-alone simulation system; Running the test to verify that the simulation system is available.

The testing results proved that the substation simulation system can run correctly. It provides a new way for learning power system substation knowledge.
