摘要

结合新型背靠背笼障转子耦合内外双定子无刷双馈发电机,提出一种无速度传感器直接功率控制方法。将电机内、外同相功率绕组及内、外同相控制绕组各自串联连接,采用超螺旋滑模控制及SVPWM技术,以固定开关频率驱动控制绕组机侧变流器功率器件,以模型参考自适应系统和Popov超稳定性理论设计发电机速度观测器,取代易发生故障的传统机电式转速/位置传感器。通过12/8极50 kW样机控制系统的特性仿真,验证了所提无速度传感器超螺旋滑模直接功率控制策略的正确性和有效性。

Abstract

A novel dual-stator brushless doubly-fed generator （DS-BDFG） coupled with inner and outer back-to-back cage-barrier rotor and an improved speed sensorless direct power control （DPC） are presented. The inner and outer in-phase power winding and control winding are all connected in series, respectively, the super-twisting sliding mode （STSM） and space vector pulse width modulation （SVPWM） control technologies are used to drive and control the power devices of the machine side converter （MSC） of the control winding with an fixed switching frequency. The model reference adaptive system （MRAS） and Popov hyperstability theorem are applied to design the generator speed observer and used to replace the traditional electromechanical speed/position sensor which is prone to failure. With the simulation results of the 12/8-pole 50 kW prototype control system, the correctness and effectiveness of the proposed sensorless super-twisting sliding mode direct power control （STSM-DPC） strategy are verified in detail.
