Application of parallel processing techniques to the simulation of power system electromagnetic transients

The authors propose the use of parallel techniques for the computation of power system electromagnetic transients in a multiprocessor environment. System partitioning and parallel solution methods are described. Questions regarding computational load balancing and communication overheads are discussed and techniques are presented to improve the proposed method with respect to those matters. In order to demonstrate the feasibility and to assess the performance of the proposed techniques, a parallel electromagnetic transients program for a multiprocessor environment has been developed. Tests using real power networks of different sizes, executed in an eight-processor hypercube machine, have shown promising performance indices.<
