PURPOSE:To perform calculation in a short time so that the calculation can be completed in an accurate period of time even when the number of generators increases by respectively providing arithmetic devices for the dynamic characteristics of generators 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 power and terminal power information of the generator outputted by a means (second arithmetic means) 2 for calculating the power transmitting state of an electric power system network and calculates the state of the generator at every step of integral time. The first arithmetic means 1 outputs the information of a voltage induced in the generator to the second arithmetic means 2 through a communication means 3 and the means 2 makes calculation by using the information and the power transmitting state of the network. After the calculation, the second means 2 outputs the output voltage and terminal voltage information of the generator to the first means 1 through the communication means 3. By alternately processing the means 1 and 2, the dynamic change of the entire power system including the generator is successively simulated. Therefore, the calculation can be executed in a short time and the calculating time can accurately be managed even when the number of generators increases. |
