| Abstract: | Taking a 400W generator used in PM synchronous wind power generator system as an example, this paper proposes the calculation method of electromagnetic field of motor un- der different operating conditions. The saturated synchronous reactance of generator with perma- nent magnets embedded in external surface structure of rotor is calculated. Based on this, the variation law of synchronous reactance parameters of generator under different operating condi- tions are further analyzed and the relevant experimental verification is carried out. It can pro- vide a reference for further research on design of control system and operating performance of wind power generators. |
