摘要
分析均匀传输线和PWM整流器结构,建立了牵引网谐波电压和谐波电流分布特性方程以及交直交机车谐波电压特性方程。进一步构建牵引供电系统-机车联合系统谐波模型,分析得出联合系统谐波电压和谐波电流的分布特性。
The equations for distribution of harmonic voltage and harmonic current of the traction power supply network as well as the equation for harmonic voltage characteristics of AC-DC-AC locomotive have been established on basis of analysis of uniform transmission line and PWM rectifier structure. A further harmonic model for traction power supply system and locomotive combined system has been established, and the distribution characteristics of harmonic voltage and harmonic current of combined system have been obtained on basis of the analysis.
