摘要: Because of using the nonlinear high-power, single-phase, multi-step full wave or bridge rectifier electric locomotive in electrified railway, railway traction power supply system has serious quality problems, which affect safe operation and impact local grid adversely. Aiming at a homogenization model inverter is established, robustness active filter analyzed based on H- infinity control theory. Simulation results show that harmonic effect good H-infinity control. Under various parameters perturbation, THD changed relatively small, can well follow load strong robustness. So suppression wide application prospects.
