Abstract: A dynamic stability analysis and control method for a voltage sourced converter based high voltage direct current (VSC-HVDC) transmission system. The method includes the following steps: unlocking a converter station of the VSC-HVDC transmission system to make the VSC-HVDC transmission system run in a non-island control mode; extracting corresponding parameters of the VSC-HVDC transmission system, wherein the parameters include an effective voltage value Ut0 of an AC system, an outgoing reactive power Qvsc0 of the VSC-HVDC transmission system, a gain kp of a phase-locked loop (PLL), and a proportional integral time constant ki of the PLL; calculating a short-circuit ratio (SCR), an unit value of Ut0 and an unit value of Qvsc0; calculating a key stable component; checking the sign of the key stable component to determine the stability of the VSC-HVDC transmission system.
