ABSTRACT:
An electric power system simulator comprising first calculator which calculates a generator dynamic characteristic, second calculator which calculates a load dynamic characteristic and third calculator which calculates power transmission condition of an electric power system network, then the first calculator cyclically obtains an amplitude and a phase of an internal induced voltage of the generator based on data on an output power and a terminal voltage of the generator, and the second calculator calculates a load equivalent admittance at predetermined time based on data on an A.C. voltage at a load installation point, and the third calculator calculates a current flowing in each element of the electric power system based on respective data obtained by the first calculator and the second calculator and an electric power system network impedance to obtain the output power and terminal voltage of the generator, so that a condition change of the electric power system including the generators is serially simulated by alternately executing the calculations of the first and the second calculators and the calculation of the third calculator.
