Study on the development of real-time digital simulation based on Matlab

This paper presents a new method to implement real time digital simulation based on a PC. This method uses the MATLAB as the whole simulation start point. First, SIMULINK and Power System Blockset is used to build up system models or controller blocks, then Real time Workshop is employed to build up the C/C++ program from the SIMULINK/PSB models. Finally, by integrating the data through the D/A and A/D conversion interfaces, the real-time simulation or closed-loop testing can be done. In this paper, the model and method of closed-loop testing of real PSS device have been described. Issues involved in the real-time simulation and closed-loop testing were discussed.
