Abstract:
An AC excitation synchronous condenser and a control method, an AC-excitation induction machine, a full-controlled AC excitation converter, a grid-side converter and a controller. The AC-excitation induction machine is the core power converting device, and its stator and rotor windings are AC windings with terminals. The controller is configured to control the full-controlled AC excitation converter to perform excitation and speed regulation on the AC-excitation induction machine and also control the grid-side converter to ensure the excitation capability of the full-controlled AC excitation converter, so that support and regulation of the active power and reactive power are achieved.

Claim (Index 7):
The control method of  claim 4 , wherein the step S 3  specifically includes: obtaining an instantaneous reactive power Q output from the AC excitation synchronous condenser to the local power grid, receiving the reactive power command Q*, and according to a rotor maximum reactive current command I* rq max  and a rotor minimum reactive current command I* rq min  that are preset, obtaining a rotor reactive current command I* rq  through proportional-integral operation, in which the rotor reactive current command I* rq  is calculated by the following formula: I rq * \ue89e { I rqmin * I rq * < I rqmin * K pQ \ue8a0 ( Q - Q * ) + K iQ \ue89e \u222b ( Q - Q * ) \ue89e dt I rqmax * > I rq * > I rqmin * I rqmax * I rq * > I rqmax * , where K pQ  represents a proportional coefficient of an reactive current regulator, and K iQ  represents an integration coefficient of the reactive current regulator.
