PROBLEM TO BE SOLVED: To make effective use of operation independency in conducting computation of simultaneous ordinary differential equations on the internal condition of a generator and a load while ensuring preference of a parallel computer system of bus coupling type shared memory system in a transmission network computation. SOLUTION: This power system computing device 1 is provided with a bus 15, a plurality of processors 10 which consist of central processing units 10 and local memories 12, and a shared memory 16. In a computing process of a simultaneous ordinary differential equation on the internal condition of a generator and a load, the respective processors 10 conducts computing using data 14 on the internal condition of the generator and the load on the local memories 12. In a process where transmission network computation is computed by solving an simultaneous equation, the respective processors 10 conducts the allocated transmission network computation using data 17 for transmission network computation of the shared memory 16. |
