PURPOSE:To make the generator operating situations of a simplified model and a strict model agree with each other satisfactorily and judge the stability with a high speed and with a high accuracy by a method wherein braking terms are repeatedly adjusted until the characteristic values of the simplified model and the characteristic values of the strict model come sufficiently close to each other. CONSTITUTION:A dynamic stability monitoring system is composed of an information transmission apparatus 2-1, an information transmission apparatus 2-2, an electronic computer 4 and a man-machine.interface apparatus(MMI) 5 which displays processed results. The electronic computer 4 executes processing operation concerning the dynamic stability in accordance with information from a power system 1 such as the voltage and the output of a generator, the active power and the reactive power of a load and active power flow. Equations of the characteristic values of a strict model and the characteristic values of a simplified model are produced. Braking terms are repeatedly adjusted so as to have the characteristic values of the strict model and the characteristic values of the simplified model sufficiently close to each other and whether errors are sufficiently small or not is judged. |
