PROBLEM TO BE SOLVED: To lead out a contracted system which ensures the result of stability computation by extracting time series data at a junction from the result of stability computation aimed at an original system, extracting unknown parameters on the basis of this, and determining various constants of the contracted system from the unknown parameters. SOLUTION: A detailed stability computation on an original system is performed (ST1), and from that computation result, time series data at the junction between a contracted part and a noncontracted part of the original system is extracted (ST2). Next, unknown parameters are extracted on the basis of the time series data (ST3), and from these, series constants are computed (ST4), and this generator data is contracted (ST5). Consequently, leading out of a contracted system which ensures the result of stability computation becomes feasible, since constitution is made so as to determine various constants of the contracted system from the unknown parameters. |
