PROBLEM TO BE SOLVED: To simulate an electric power system with a plurality of computers, by preparing the simulating data of the facilities of the electric power system at every state-changing pattern when a recognized result is in a simulated state. SOLUTION: A simulating means 152 of a simulator discriminates whether or not the operating state of a computer 101 for controlling monitor is '3', by discriminating whether or not processing is executed by means of the computer 101, based on the computer identification number of a simulation kind in formation section 157.
