SIMULATOR FOR ELECTRIC POWER SYSTEM

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.
