Optimal Configuration of Converter for HVDC Transmission System

A novel method is proposed for configuring a power electronics converter circuit for optimal performance in HVDC transmission system. It is configured depending upon the desired output voltage pulses. Assuming high number of pulses in output voltage optimal configuration is obtained by achieving maximum possible output voltage, minimum Peak Inverse Voltage, and by obtaining transformer utilization factor value near unity. This paper suggests an analytical way of designing the converter circuit based on certain assumptions. A mathematical model of the scheme is developed. Detailed analysis and simulation results are presented in LabVIEW 7.1 software.
