Calculation of Starting Currents and Losses for Damper Bars of Pumped Storage Machines by SFC

摘要：

For the pumped storage machines started by static frequency converter (SFC), the mathematical model of multi circuits is established considering actual arrangement of the damper bars based on the multi-circuits theory of the electrical machines. Then the mathematical simulation of static frequency converter starting is carried out by MATLAB, and the transient currents and losses of the damper bars are caculated. Finally, a sample machine is given as the example. The result indicates that the stronger the saturation is, the larger the influence on the field current is, but the influence on the torque is very small.
