RESEARCH ON DEVELOPMENT AND CONTROL STATUS OF POWER QUALITY FOR ELECTRIFIED RAILWAY

摘要

According to the fact that the existing power quality control, the measure and means were introduced, analyzed and compared in detailed. The advantages and disadvantages of this measure and means can be pointed out. Aiming at the measure and means existing power quality control, project control of integrated suppression and development trend was put forward on controlling power quality electrified railway in the paper. From reliability, technology and economy point, a new injection-type hybrid active power filter (HAPF) combined with magnetron static VAR compensator (SVC) make to compensate effectively passive power, eliminate drastically harmonic and improve load imbalance current. Used the recommend methods can improve reliability and security of electrified railway.
