高速磁浮列车用混合滤波器设计的仿真研究

高速磁悬浮列车系统的谐波是一种典型的强非线性、冲击性负荷,是一种重要的新型谐波源,在没有补偿措施时,它会带来较严重的电网谐波问题。针对高速磁悬浮列车系统谐波的特征,运用自适应谐波检测方法对谐波进行检测分离,通过有源滤波器和无源滤波器的有效配合,最终达到谐波抑制,改善功率因数,优化电网电能质量的目的。

Study on Simulation of Design of Hybrid Filter Used in High Speed Maglev System

As a typical strong nonlinear surge load,the harmonic produced by the high speed maglev system is an important new type of harmonic source. Without compensation measures,it will bring severe harmonic problem to the network. In view of the characteristics of harmonic of high-speed maglev system,the hybrid filter uses adaptive neural network to detect and isolate the harmonic,and finally reaches the objective of harmonic suppression,improves power factor and optimizes the electricity grid quality through the effective co-ordination of active filter and passive filter.
