Hello everyone, I would like to ask a little help from you guys. I am designing a Permanent Magnet Synchronous Generator (PMSG) for a Wind turbine application which is of direct drive (DD) type. Being a DD type PMSG the frequency of the output is very low and hence I had to employ converter Inverter pair to improve the frequency. Now, how do I calculate the power factor (PF) of the PMSG? As the PMSG is not directly connected to the load, I believe that the PF does not depend on the load nature. Can someone help me by providing any equations or any research papers and any other material that can help me finding out the PF of the PMSG. Thank you very much.
