摘要
提出了基于分形理论的高压输电线路故障类型识别新方法。根据故障后对各相暂态分量电流和零序暂态电流的分形维数计算和分析,提取和形成了故障类型识别判据。通过对不同故障类型和特征的大量ATP仿真和检验测试,证明了应用分形理论识别输电线路不同故障类型的可行性和有效性。
A new approach of fault type recognition in transmission line is proposed based on fractal theory. The criterion of fault type recognition is extracted and formed by the calculation and analysis of fractal dimension to the transient component current of each phase and zero sequence. Large amount of results of ATP simulations and verifying tests to different fault types show that the proposed method based on fractal theory is feasible and effective.
