yes, in this case generator never works as a motor...
Although generator dosent need squirrel cage due it is not directly conected to the grid, what about the harmonics surged by the rectifier? does squirrel cage have any advantege about these harmonics in terms of shoe heating or losses...
Hi all,
The standar configuration of a Synchronous generator with salient poles has a squirrel cage in the pole shoe in order to damp the load oscilations.
In some wind aplications, generator is completely decoupled from the grid by a power electronic converter connected to the stator...
Thanks aokalde, Im going to use the discharge resistor method. Now Im looking for the way to select the dischage resitor.
I have read that the value of the discharge resitor must be around 6-10 times the field resistance. Higer the discharge resistor higer is the induced voltage on the exciter...
Im working with two ideas.
First one is starting motor with discharge resistor (rotor) and make the conexion of the DC field through the SPM (Synchronous protection control/ GE). Due the starting is on no load, I dont know if I can conect the DC field excitation, supresing the resistors when...
