Powerformer is a net new high-voltage generator that can be set directly to system. The simulation method of Powerformer loss of excitation based on MATLAB/simulink is proposed. Using the simulation method to study slip during Powerformer loss of field, and analyze slip impact on the electric value of Powerformer stator and rotor. From the rotor heating, it is not possible affect the safe operation of the rotor because the rotor body additional temperature, during the asynchronously operation of Powerformer loss of excitation. It proves the transition from out-of-step to the steady-state asynchronous operation after Powerformer loss of excitation is asynchronously operation. It provides a reliable basis for the Powerformer actual operation.
