摘要：
Brushless doubly-fed generator (BDFG) has two sets of different number windings on the stator, the power winding and control winding, and adopts the hybrid rotor structure consisting of magnetic barrier and cage. Open winding brushless doubly-fed generator (OW-BDFG) opens the control winding entirely and connects a converter to each end. When the two converters use a common DC-bus, the system forms a zero sequence current loop and produces the zero sequence current which affects the efficiency and performance of the system under the action of common-mode voltage. A voltage modulation method was proposed to eliminate common-mode voltage based on direct power control (DPC) for the special structure, both to achieve the decoupling control of active power and reactive power, and to solve the zero sequence current problems existing in the common DC-bus OW-BDFG system. Finally, the effectiveness and superiority of proposed common-mode voltage elimination for open winding brushless doubly-fed generator based on direct power control(CMVE-DPC) method is verified through the simulation and experiment research and comparison analysis. © 2018, Harbin University of Science and Technology Publication.
