Abstract:his paper discusses the factors that influence the phase-advancement operation of large non-salient pole generator. It is found that the generator voltage will change in phase-advancement operation, which affects the boundary of steady-sate stability and loss of excitation impedance circle. This paper studies the principle to harmonize the setting of low-excitation limited set with loss of excitation protection. Finally, some suggestions are made via several examples of field applications.
Keywords:non-salient pole generator  phase-advancement operation  low-excitation limited set  loss of excitation protection  asynchronous impedance circle
