The Impact

At present, the research on wind turbine low voltage ride through (LVRT) behavior is one of hotspots in wind power industry. With increasing share of wind power in the grid, it is important to enhance the LVRT performance of wind turbines to guarantee the safety and reliability of the grid. The phenomenon of voltage double-dip is one of cases during the voltage dips. In this paper, the voltage double-dip phenomenon is described, and the stator flux attenuation of DFIG wind turbine in the voltage dip is analyzed. The results show that when the second voltage dip occurs, the initial value of the stator flux should be considered. Finally, by on-site testing results, the impact of voltage double-dip to the wind turbine is verified, if the initial value of the stator flux is not considered, and the interval of two voltage dips is different.

By incorporating the merits of partitioned stator and flux modulation techniques, the partitioned stator flux modulation motors featuring high torque, have attracted much attention. This paper investigates four partitioned stator flux modulation motors with different types of PM arrays, including surface-mounted type, consequent-pole type, Halbach-array type, and half-Halbach type. The influences of key parameters on the average electromagnetic torque is conducted and compared. Then, based on the optimal designs, four motors are compared in terms of magnetic field distribution, back-electromotive force, torque characteristics, loss and overload ability. The result reveals that the half-Halbach motor is capable of utilizing more PM to improve electromagnetic torque. Also, the consequent-pole motor achieves the highest torque per PM usage. In addition, performance comparison under the same PM usage is carried out. The result shows that the half-Halbach motor not only exhibits the highest average torque but also achieves the highest PM utilization. Last, the prototype of half-Halbach motor is built for experimental verification.
