Abstract Ultra-high voltage direct current (UHVDC) block will seriously impact the transient stability of the sending-end system of wind power transmitted by mixed UHVDC/ultra-high voltage alternating current (UHVAC) system (WIND-UHVDC/AC system). To improve the transient stability of the sending-end system, the equation of electrical power of the synchronous generator (SG) in the sending-end system was deducted firstly, the impact of active power fast reduction of double fed induction generator (DFIG) after UHVDC block on the rotor angle stability was analyzed based on the equal-area criterion (EAC), and the control scheme of the active power fast reduction of DFIG was proposed. Then, based on the analysis of UHVDC block and capacitors switch-off on the transient voltage characteristics, the control scheme of reserving partial capacitors after UHVDC block to improve the transient voltage stability of UHVAC lines was proposed. Besides, the impact of variation in the capacitors switch-off time delay on the rotor angle stability was analyzed. Finally, the simulation results of the actual WIND-UHVDC/AC system in China’s northwest power grid show that active power fast reduction of DFIG can improve the rotor angle stability, reserve capacitors can improve the transient voltage stability of the UHVAC lines and has little impact on the rotor angle stability.

Key words： Wind power transmission UHVDC block active power fast reduction capacitors switch-off time delay voltage stability rotor angle stability
