The Use Of A Multiprocessor Network For The Transient Stability Problem

This paper examines the possibility of using a dedicated multiprocessor network to do the step-by-step computations needed in the digital simulation of the dynamic response of a large power system. This multiprocessor network would use a general purpose digital computer for the input and output. It is found that over 97% of the computations for a typical 1723-bus, 396-machine, stability study could be done in parallel. Approximately 30% of the computation time is spent solving the network equations, I = YE. Various algorithms for this part of the solution and ways of scheduling the work assignments to the processors are discussed.
