VSC-HVDC Control Strategy Research and Simulation Analysis

With the development of high-power full-controlled power electronic devices based HVDC voltage source converter (VSC) and pulse width modulation (PWM) technology (VSC-H VDC) technology has become a reality. Currently VSC - HVDC technology in foreign countries in the theoretical study of the transition phase to the experimental system, while the domestic is just beginning, many of the basic theory and applications related to basic issues to be studied. In this paper, based on existing research, analyzes power VSC-HVDC system control strategy proposed dq0 coordinates using a steady state model, and based on the model , designing the control program. Finally, to build a system using SIMULINK simulation model for a steady-state simulation analysis.
