abstract
This paper presents a new approach for interactive protection system simulation. In the new approach, power system transients are simulated using an Electromagnetic Transients Program (EMTP), while protective relays can be modeled using any high level language or commercially available software package, such as MATLAB. The interactions between power systems and relays are implemented by using an `interaction buffer'. Using this technique, the EMTP can be run in single-step, multiple-step, or mixed mode. This new approach makes the protection system simulation quite efficient, flexible and accurate.
