PURPOSE:To make the computing quantity of electric power system network calculation constant by alternately processing each calculating means of the dynamic characteristic of a generator, dynamic characteristic of a load, and the power transmitting state of an electric power system network. CONSTITUTION:A means (first arithmetic means) 1 for calculating the dynamic characteristic of a generator inputs the output voltage and terminal voltage of the generator and calculates values of the amplitude and phase of a voltage induced in the generator at every step of integral time. A means (second arithmetic means) 3 for calculating the dynamic characteristic of a load inputs the magnitude of the AC voltage at a point where a load is set and calculates the equivalent admittance of the load at every step of integral time. A means (third arithmetic means) 2 for calculating the power transmitting state of an electric power system network performs system network calculation by using the amplitude and phase of the voltage induced in the generator calculated by the first means 1, the equivalent admittance calculated by the second means 3, and the impedance of the network. |
