Power angle control of grid-connected capacitor-tapped multi-module voltage source converter
HVDC transmission suits transmitting large amounts of renewable energy power over long distances with low transmission losses. The Capacitor-Tapped Multi-module Converter (CT-MC) can be employed effectively to integrate the transmitted power through the HVDC lines into a medium voltage AC grid. In this paper, the power angle control of grid-connected the CT-MC is introduced. The power-angle control is simple and can be implemented easily, where the active power is generally controlled via controlling the phase-angle shift between the Voltage Source Converter (VSC) and the AC system, while the reactive power is controlled via varying the VSC output voltage magnitude. The operational concept of CT-MC along with its power angle control is Prasented. Simulation results for the system during normal as well as abnormal operating conditions are Prasented for validation using Matlab/Simulink platform.
