Optimal DC Voltage Design for High-Speed Traction Power Systems Using LLC-HPQC Control

J. Praveena, Y. Dhamodharam


Abstract: The economic development of any country depends on the utilization of energy resources. The worlds most widely used energy resources being electric energy. . Energy being consumed in different forms needs converters and they become very efficient with the invention of power electronic devices. For comprehensive compensation under optimal dc operation voltage in high-speed traction power supplies a hybrid power quality compensator (HPQC) is proposed in this project. Compensation device capacity, power consumptions, and installation Cost can be decreased by reduction in operation voltage of the HPQC. The parameter design procedures for minimum dc voltage operation of HPQC are being explored. It is shown through simulation results that similar compensation performances can be provided by the proposed LLC- HPQC with reduced dc-link voltage level compared to the conventional railway power compensator. A LLC-HPQC is able to afford reactive power, system unbalance, and harmonic compensation in co-phase traction power with reduced operation voltage and without increasing the transformers turns ratio. The co phase traction power supply with proposed HPQC is suitable for high-speed traction applications.
