Start-up torques of permanent magnet synchronous generator with non-overlapping concentrated windings

摘要

In this paper there are analyzed the start-up torques of PMSGs that are directly connected to the turbine and are used in wind power plants (WPP). In such generators the start-up torques are high, which leads to necessity of faster wind to overpass the torque, but that shortens the diapason of working wind speed. There are researched the values of startup torques for PMSG's model with 3-phase winding on (Z1 = 18) stator teeth. The values are obtained by different design parameters, such as: PM's pole pair number, opened and half-opened slots. The torque is calculated in software QuickField.
