摘要：
The novel dual-stator brushless doubly-fed generator（DS-BDFG）consists of inner and outer power windings and inner and outer control windings. The inner power and control windings are coupled by the inner magnetic field of inner cage-barrier rotor，the outer power and control windings are coupled by the outer magnetic field of outer cage-barrier rotor，and the inner and outer rotors are designed as back- to- back rotors where isolated with a non- magnetic ring. A novel direct power control（DPC）for the dual- stator brushless doubly-fed wind power generator is proposed. The inner and outer power windings also inner and outer control windings are connected in series，respectively，where the electromagnetic characteristics of the inner and outer power wingdings also inner and outer control windings can be kept consistent. By synthesizing the output values of the active and reactive power hysteresis comparator of power winding and the flux sector number of control windings，the voltage space vector of machine side converter can be determined by using the look-up table（LUT）method. The characteristic simulation and experimental results of the 12/8 pole 50 kW prototype control system under the action of step signal are studied by quantitative comparison. The correctness，feasibility and effectiveness of VSCF，MPPT，reactive power control and unit power factor control（UPFC）of the proposed LUT-DPC for the novel DS-BDFG in the range of speed variation from sub-synchronous to super-synchronous are verified. © 2024 Science Press.
