Analysis and Design of PWM-CSC for HVDC Transmission Systems

Abstract

The pulse width modulation current source converter (PWM-CSC) has been regarded as one of many interesting circuit topologies in high-power systems. This paper analyzes the influence of system parameters on the power operating range of PWM-CSC, and designs the parameters for PWM-CSC applied to HVDC transmission system. A 250 kV/500 MW PWM-CSC based HVDC transmission system is built using PSCAD/EMTDC software, and the experimental platform was built to verify the correctness of the analysis and the feasibility of the design.
