Abstract :
The authors present results of tests with a parallel implementation of a power system dynamic simulation methodology for transient stability analysis in a parallel computer. The test system is a planned configuration of the interconnected Brazilian South-Southeastern power system with 616 buses, 995 lines, and 88 generators. The parallel machine used in the computer simulation is a distributed memory multiprocessor arranged in a hypercube topology architecture. The nodes are based on the Inmos T800 processors with 4 Mbytes of local memory. The simulation methodology is based on the interlaced alternating implicit integration scheme in which the network equations are re-ordered such that the network admittance matrix appears in the block bordered diagonal form and is then solved by a combined application of the LU factorization and the conjugate gradient method. The results obtained show considerable reduction in the simulation time
