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 5):
The control method of  claim 4 , wherein the step Si specifically includes: if the set working mode is to obtain a reactive power command from the superior command, receiving a superior reactive power command Q* in  and obtaining a reactive power command Q*=Q* in ; or if the set working mode is to obtain a reactive power command from the local control, obtaining a measured voltage U of the local power grid and then obtaining a reactive power command Q*=K pu (U N \u2212U)+K iu \u222b(U N \u2212U)dt through proportional-integral operation, where K pu  represents a proportional coefficient of a reactive power regulator, and K iu  represents an integration coefficient of the reactive power regulator.
