摘要： PURPOSE:To prevent a phase from exceeding a prescribed value by adding or subtracting a set value to or from the phase when the phase deviates from a prescribed value after the phase is calculated. CONSTITUTION:A means (first arithmetic means) 1 for calculating the dynamic characteristic of a generator calculates the state of the generator at every step of integral time from the output power and terminal voltage information from a means (second arithmetic means) 12 for calculating an electric power system network. The first means 1 outputs the amplitude and phase of a voltage induced in the generator to the second means 12. The means 12 finds the output power and terminal voltage information of the generator by using this information and various constants of an electric system network and outputs the calculated results to the first means 1. Moreover, the second means 12 uses the value obtained by subtracting a set value when the phase of the first means 1 exceeds a prescribed value which is an integer multiple of 360 deg. as a phase. The first and second arithmetic means 1 and 12 are alternately processed so as to successively make simulation.

摘要： PURPOSE:To perform a realistic display by outputting the state of an electric power system at every step of integral time during arithmetic operations made by an electric power system simulator and displaying the output on a man- machine device. CONSTITUTION:An electric power system simulator 3 provided with CPUs 1 and communication lines 2 can make arithmetic operations at a speed close to the progressing speed of the actual phenomenon of an electric power system and outputs the state of system at every step of integral tie during operations. A man-machine device 4 displays the output of the simulator 3 and also can make interrupting operation to the simulator 3 for a state change at any time. Therefore, the state of the system can be displayed realistically on the man- machine device 4 in real time. Moreover, the simulated situation can be changed during the simulation and data can be displayed and processes can be executed as if an actual trouble shooting is processed.

摘要： 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.

摘要： 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.
