ELECTRIC POWER SYSTEM SIMULATOR

摘要

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