新型双边供电系统谐波谐振特性分析
Analysis of Harmonic Resonance in New Bilateral Power Supply System
摘要
Abstract
In order to study the resonant mechanism of bilateral power supply system,a new bilateral power supply sys-tem that connects the reactors in series with feeders of traction network is proposed,and its structure and working prin-ciple are introduced. Through building a harmonic mathematical model of the proposed system,the system resonance mechanism is analyzed. Through building a system simulation model,the impedance-frequency characteristics of the bi-lateral power supply system and the transmission characteristics of high-order harmonics in traction network are ana-lyzed. The results show that the longer the traction network,the lower the resonance frequency of the system. When the harmonic currents with frequency close to the resonance frequency of the new system are injected into the traction net-work,resonance could occur and the harmonic currents will be seriously enlarged.关键词
