Study on Chaos-based Harmonic Suppression Methods for Traction Power Supply System

分析了高次谐波对牵引供电系统的危害,针对既有研究结果,基于Chaos理论在谐波抑制方面的特性分析了杜芬方程的滤波机理,提出了利用杜芬系统抑制高次谐波的新方法,并通过仿真实验验证了该方法的可行性,为牵引供电系统高次谐波的抑制提供一种新思路。

The paper analyzes the hazards to the traction power supply system caused by the high order harmonics,analyzes the filtering mechanism of the Duffing equation with respect to the existed results of study on the basis of the characteristics of Chaos theory on harmonic suppression,puts forward a new method to suppress the higher order harmonics by application of Duffing system,and the feasibility of the method has been verified by simulation experimental tests,providing a new way of thoughts on suppression of higher order harmonics for traction power supply system.
