Research of Electrified Railway Harmonic Suppression Based on H-infinity Control
Because of using the nonlinear high-power, single-phase, multi-step full wave or bridge rectifier electric locomotive in electrified railway, the electrified railway traction power supply system has serious power quality problems, which affect safe operation of the electrified railway and impact the local power grid adversely. Aiming at the electrified railway power quality problems, a homogeni...
متن کاملResearch on Synthesis Control of Power Quality for Electrified Railway
This paper analyzes necessity of synthesis control of power quality aiming at characteristics of traction power supply system for electrified railway. According to the fact that the existing power quality control, the measure and means were introduced, analyzed and compared in detailed. From reliability, technology and economy point, the project of synthesis Control was put forward on power qua...
متن کاملVoltage Unbalance Problems and Solutions for Electrified Railway Systems
Voltage and current unbalance problems of power networks due to AC electrified railway systems are studied and their influences such as the voltage unbalance factor and the current negative sequence contribution factor injected to the network are calculated. Several methods can be used for reducing the power quality unbalance problems which have been proposed and the best of them is chosen by c...
متن کاملInduction Motor Characteristics and Applications for Dc Electrified Railway Systems
Induction motor structures in DC electrified railways with their dynamic performance are studied. Characteristics of the current, voltage, electrical and mechanical torque and active and reactive power in accelerating, normal and regenerative braking are investigated. The characteristics of the induction motors used for Tabriz urban railway are simulated with PSCAD/EMTDC software proving the in...
متن کاملRobust Control Design for Active Flutter Suppression
Flutter is an unstable oscillation caused by the interaction of aerodynamics and structural dynamics. It can lead to catastrophic failure and therefore must be strictly avoided. Weight reduction and aerodynamically efficient high aspect ratio wing design reduce structural stiffness and thus reduce flutter speed. Consequently, the use of active control systems to counter these adverse aeroservoe...
