Structural modeling for simulation of power electronic systems

Power electronic systems are described by nonlinear differential equations, typically of high order. Simulation of such systems increasingly requires the high speeds available only on multiprocessor computing systems. However, the traditional methods for partitioning the system are rather inconvenient, primarily because of the additional burden created by the current operation associated with distributed systems. The concepts and methods of structural modeling provide a way to overcome this difficulty. The essence of structural modeling is the assignment of some specific computing resource to each object of the simulated physical system. The simulation of each object then operates as a formal independent procedure, and interactions between objects are implemented on a data link level. This allows parallel execution of the separate procedures on the allocated multiprocessor computing hardware. This provides two advantages: (1) a decrease in simulation time, and (2) simplification of the programming process.
