摘　　要：解微分方程算法在电力系统输电线路微机距离保护中得到了广泛应用,特别是在中、短输电线路中取得了较为满意的效果。基于解微分方程算法的基本原理,分析了该算法实现的微机距离保护在电力系统输电线路相间故障、接地故障以及高阻接地故障形式中的应用,并从频域和误差分析得到该算法的性能,为该算法完全合理和精确的实际应用的进一步研究提供理论依据和参考价值。Algorithm for solving the differential equation applies increasingly in transmission micro-processor distance protection in electric system. Especially for secondary and short distance transmitting system, the result is satisfying. Based on elementary theory of algorithm for solving the differential equation, the application of distance protection promised is analyzed by this algorithm in phase faults,grounding faults and high resistance grounding faults for transmission system, and provided the function of this algorithm from the standpoint of frequency field and error analysis and raises theoritic foundation and reference value to further research of reasonable and precise application of this algorithm.
