In view of the need of a boundary condition to obtain the unique solution for the steady-state constraints of permanent magnet synchronous generators（PMSGs）that are a set of indeterminate equations with the reactive power output of the machine-side converter unfixed，steady-state solutions based on the stator current/voltage orientations are proposed.Because of inconsistency with the reactive power balance of the machine-side-converter，the solutions under two orientations are different.Further consideration of the power dispatch by adjusting the rotor speed or the pitch angle，steady-state solutions to PMSG are proposed.The numerical results show that:（1）the stator current orientation yields less active loss and higher efficiency，but absorbs more reactive power;（2）with increased wind speed，the PMSG absorbs more reactive power，the efficiency decreases with stator current orientation，but increases with stator voltage orientation;（3）active power dispatch may be realized by changing the rotor speed or the pitch angle，while the efficiency is different，and adjusting the pitch angle yields better convergence than adjusting the rotor speed.
