In order to analyze the performance of powerformer under loss of excitation (LOE) condition more effectively, in this paper, firstly, based on MATLAB/Simulink, the simulation model is constructed, the direct short-circuit LOE and the excitation winding forms short-circuit LOE with de-excitation resistance are simulated by the model; Secondly, the waveforms of excitation current, rotor speed, active power, reactive power, stator current are given; Thirdly, the results are analyzed detailed. In addition, the model can also simulate other LOE faults.
