This paper studies the mechanism of spinning reserve on transient voltage stability in ultra-high voltage (UHV) DC/AC hybrid power grids. Taking an actual received power grid with an UHVDC system as an example, the transient voltage stability is introduced and a certain scale of spinning reserve has to be retained to keep the transient voltage stability of the system. And then, the steady state of synchronous generators with different spinning reserve is studied using the method of phasor diagram analysis. At last, the relation of spinning reserve, excitation voltage, and dynamic reactive power is analyzed and the mechanism of spinning reserve on transient voltage stability is revealed. The actual received power grid is used to demonstrate the validity of the mechanism.
