  1. In digital relay, the percentage of noise will increase rapidly with the increase of sampling rate when derivation calculus is substituted by sampled difference term. to solve this problem, a new method using fragment function integrated with the least square algorithm is proposed in this paper. the influence of white noise is greatly reduced and the accuracy of the dead angle calculation is nicely improved after adopting the new method

    在數字式保護中,如果用差分代替求導將導致噪聲的百分比誤差隨著采樣頻率的提高而劇增,本文對此進行了分析並提出了用分段樣條函數最小二乘法來計算電流波形的導數值,以便在提高采樣率的同時降低噪聲誤差的影響,並將其應用於基於32位浮點dsp的新型變壓器保護裝置。
  2. The derivation of a sort of simple plural calculus
