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 6):
The control method of  claim 4 , wherein the step S 2  specifically includes:\n obtaining a measured frequency f of the local power grid and according to a rated rotating speed synchronization command \u03c9* rN , a rated frequency f N  of the local power grid, a maximum rotating speed command \u03c9* r max  and a minimum rotating speed command \u03c9* r min  that are preset, obtaining a rotating speed command \u03c9* r  through proportional-integral operation, in which the rotating speed command \u03c9* r  is calculated by the following formula: \n \u03c9 r * \ue89e { \u03c9 rmin * \u03c9 r * < \u03c9 rmin * K pf \ue8a0 ( f - f N ) + K if \ue89e \u222b ( f - f N ) \ue89e dt \u03c9 rmax * > \u03c9 r * > \u03c9 rmin * \u03c9 rmax * \u03c9 r * > \u03c9 rmax * , where K pf  represents a proportional coefficient of a rotating speed command regulator, and K  if  represents an integration coefficient of the rotating speed command regulator.
