同杆双回线路行波故障测距的关键问题研究
|
摘要
为了提高同杆双回线路行波故障测距的准确度,针对故障行波选取和行波检测,提出了一种新的故障行波选取方法和行波检测方法。同杆双回线路各相线间耦合复杂,经传统相模变换后的多模分量传播特性差异较大,采用一种新的相模变换,找出多模分量传播规律,解决了故障行波选取困难的问题。当前行波检测方法存在一些技术缺陷,将参数优化的变分模态分解和Teager能量算子相结合应用于行波检测,实现了行波检测方法的自适应性,具有较好的检测效果。采用双端行波测距算法计算故障位置,大量的仿真结果验证了所提方法的可行性和测距结果的准确性。
In order to improve the accuracy of traveling wave fault location of double-circuit line on the same tower, a new selection of fault traveling wave and a detection method are proposed for fault traveling wave selection and traveling wave detection. The coupling between each phase and each line of double-circuit line on the same tower is complex and multimode propagation characteristics after traditional phase mode transformation are of big difference. A new kind of phase transformation is adopted, which concludes the law of multimode component propagation and solves the difficult problem of traveling wave fault selection. There are some technical defects existing in the current traveling wave detection method. The variational mode decomposition after parameter optimization and Teager energy operator are combined to apply to traveling wave detection, realizing the adaptability of the travelling wave detection method with a good detection effect. Double-terminal traveling wave fault location algorithm is used to calculate fault location. A large number of simulation results verify the feasibility of the method and the accuracy of location results.
