高速铁路弓网系统谐波分析方法的研究
Research on the High Speed Pantograph-catenary System's Harmonic Analysis Method
摘要
Abstract
As the main source of the pantograph-catenary system's harmonic,off-line arc is random.It is required that the pantograph-catenary harmonic analysis method has a high degree of adaptive capacity.Aimed at solving the problem of the extraction of pantograph-catenary system's electromagnetic harmonic interference component,a method of the atomic decomposition based on NGA-MP is presented.Firstly,the pantograph system is simulated by the experiment machine,the pantograph's voltage is obtained,and the harmonic,the inter harmonic and the pulse interference components of voltage are extracted by the atomic matching.Then,the accuracy of the atomic decomposition based on NGA-MP is verified by the signal reconstruction and the spectrum method.Finally,the voltage signal that is obtained by different working conditions is decomposed by atomic matching,and the conclusion is the higher speed,the more abundant harmonic components,and the reason is analysed theoretically.Experimental results also show that the method of the atomic decomposition based on NGA-MP has the advantages of strong adaptability,high accuracy and fast calculation speed.关键词
