摘　　要：本文对无刷双馈电机在独立发电系统下的直接电压控制方案中引入了无速度传感器策略,并对它的稳定性进行了分析针对不平衡特殊负载条件下的工况,在无速度传感器控制策略中加入了特殊设计的负序控制环节实现了改进和优化,保证了在各种负载条件下系统输出PW线电压始终为对称的正弦波。仿真和实验结果表明在引入无速度传感器控制策略后,BDFIG独立发电系统仍能保持优良的特性,在多种运行工况下均能满足各项性能指标要求。This article introduced the strategy of speed sensorless control into the direct voltage control scheme of the brushless doubly fed induction generator(BDFIG)in an independent power generation system,and analyzed its stability.In order to cope with special unbalanced load conditions,a specially designed negative sequence control loop was added to the speed sensorless control strategy to improve and optimize the system performance,ensuring that the system output phase-to-phase voltage was always a symmetrical sinusoidal wave under various load conditions.Simulation and experimental results show that the BDFIG independent power generation system can still maintain excellent performance after implementing the speed sensorless control strategy,and can meet the requirements of various performance indicators under multiple operating conditions.
