<p><P>PROBLEM TO BE SOLVED: To provide a harmonic calculation parameter analysis apparatus which accurately estimates a harmonic calculation parameter and is so accurate as to estimate a worst value of the harmonic calculation parameter, and a harmonic calculation parameter estimation method. <P>SOLUTION: A harmonic calculation parameter analysis apparatus includes an analysis file 22 which has circuit connection information using an equivalent circuit 41 of an actual power system considering a transmission side and a load side. The apparatus further includes a comparator 6 which uses a harmonic calculation parameter of the equivalent circuit 41 and a harmonic calculation parameter file 23 which stores a value of the harmonic calculation parameter to perform circuit analysis in an analyzer 4, compares a value of a load-side harmonic voltage/current estimation calculation result to be solved in the harmonic calculation parameters with a value of an actual measurement result, and extracts from a database 5 analysis result data 25 having such a value that the value of the actual measurement result and the value of the load-side harmonic voltage/current estimation calculation result in the analysis result data satisfy a predetermined relationship. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
