In this paper, based on the theory of hybrid systems based on the system description , describes the basic concepts of hybrid power systems . Paper presents a computer simulation language Modelica technical principles of object-oriented design by hybrid power system simulation platform for ideas , the establishment includes generators, transmission lines, loads , transformers with OLTC tap , which can be switched capacitor group , low voltage load shedding devices, electrical braking , fast valving components or devices, hybrid power system controller electromechanical transient process simulation model library . Programmable Timed Petri Nets with a method to establish the behavior of producing hybrid controller model . Finally, the built -element model simulation analysis , results show that the platform can reflect the dynamic process of the power system confounding characteristics . This can be set up for the future of the whole power system dynamic simulation platform signed by .
