A distributed simulator for power system analysis using a hypercube computer

Abstract The use of distributed systems is expected to realize characteristics of flexibility, high modularity, ease of development, high-speed processing and cost performance in several fields. Distributed systems on parallel or distributed computers are studied in order to obtain these characteristics. We have developed a distributed simulation method for the extension or maintenance of power systems in the simulator. In this paper, we describe the distribution methods of power system simulation. First, we propose a distributed algorithm for solving the network equations of power system simulation. Second, we describe a way of mapping tasks, which are to be separated for distributed simulation, to a hypercube computer, NCube/10. In the hypercube computer, each bus and control circuits of a generator in a power system are assigned to individual processors. Finally, we present the results of installing and evaluating the proposed algorithm and distributed simulation techniques on a hypercube computer.
