| Abstract: | The solve differential equation algorithm is improved.The result of digital simulation tests show that the new algorithm performance is good.Based on the comparison of recursive least square algorithm,all-wave Fourier algorithm and the new algorithm, a realization scheme of a distance relay algorithm is proposed. The scheme has the character of inverse time lag. |

| Keywords: | digital distance protection inverse time lag solve differential equation algorithm |
