CONTRACTIVE SUPPORT METHOD, CONTRACTIVE SUPPORTING DEVICE OF SIMULATED POWER SYSTEM AND PHENOMENON ANALYSIS AND DEVICE OF POWER SYSTEM

摘要

PURPOSE:To contract a simulated power system without causing damage to the equivalence of generators by assuming an accident at an arbitrary spot of the simulated power system and by contracting plural generators whose change of quantity of state in each generator to this accident has the same inclination and whose mutual electric distance is within the designated limits. CONSTITUTION:An assumed accident analysis means 3 starts in reaction to a given contraction command, performs an accident analysis in cooperation with a power system simulation means 1 in accordance with a simultaneously given accident condition and outputs the initial quantity in quantity of state with a generator obtained by analysis on to a display means 7. Further, the assumed accident analysis means 3 analyzes the processing result of the above analysis and indicates the output on to the display means 7. An operator evaluates the analytic result, selects not less than one generator group to be contracted and commands the input into a contraction decision means 5 through an input means 8.
