TDG (Test Data Generator) attached to the 61083-4 simulates digitally recorded data for typical waveforms observed in daily measurement. Any acceptable software can determine waveform parameters within a given margin specified in IEC 61083-4. Authors could successfully analyse all the a. c. waveforms generated by the TDG using techniques, 1) FFT after an interpolation for steady a. c. and 2) a base curve for short-term a. c. The latter involves the least square method and a set of non-linear equations. The distilled parameters for both waveforms are within the specified margins (0.1% in peak value) proposed in IEC 61083-4. The details of the algorithm are to be clarified in the paper. Also mentioned in the paper is a proposed TDG's controversial behaviour in which a current-zero instant is shifted due to a discrete sampling interval.本誌: 電気学会論文誌B（電力・エネルギー部門誌） Vol.133 No.12 （2013） 特集：System Technical Performance（系統の技術性能）本誌掲載ページ: 1001-1008 p原稿種別: 論文／英語電子版へのリンク: https://www.jstage.jst.go.jp/article/ieejpes/133/12/133_1001/_article/-char/ja/
