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 8):
The control method of  claim 4 , wherein the step S 4  specifically includes: obtaining a measured rotating speed \u03c9 r  of the AC-excitation induction machine, receiving the rotating speed command \u03c9* r , and according to a rotor maximum active current command I* rd max  and a rotor minimum active current command I* rd min  that are preset, obtaining a rotor active current command I* rd  through proportional-integral operation, in which the rotor active current command I* rd  is calculated by the following formula: I rd * \ue89e { I rdmin * I rd * < I rdmin * K p \ue89e \ue89e \u03c9 \ue8a0 ( \u03c9 r * - \u03c9 r ) + K i \ue89e \ue89e \u03c9 \ue89e \u222b ( \u03c9 r * - \u03c9 r ) \ue89e dt I rdmax * > I rd * > I rdmin * I rdmax * I rd * > I rdmax * , where K p\u03c9  represents a proportional coefficient of a speed regulator, and K i\u03c9  represents an integration coefficient of the speed regulator.
