电气化铁路功率调节器综合补偿系统的稳定性与闭环跟踪能力分析
Analysis of Stability and Closed-Loop Tracking Ability for Comprehensive Compensation System of Railway Static Power Regulator
摘要
Abstract
In allusion to a great deal of negative-sequence and harmonic currents resulted in high-speed railway traction system, a railway static power conditioner (RPC) structure, which can perform large capacity power transfer, negative-sequence compensation and harmonic elimination, is proposed. Firstly, the principle of negative-sequence compensation of RPC system for V/V traction transformer is analyzed and its mathematical model and the schematic diagram of its control are built; then the influences of controller parameter variation on stability and closed-loop tracking ability of RPC system are emphatically analyzed to provide theoretical foundation for the selection of parameters; finally simulation verification of the proposed structure and model is carried out and the correctness of above-mentioned analysis is verified.关键词
