APPARATUS ACCIDENT DISCRIMINATION OF TRANSFORMER AND METHOD

摘要

The present invention relates to a transformer accident determination apparatus and method capable of determining the type and location of a transformer internal accident, and the transformer accident determination apparatus according to an embodiment of the present invention determines a normal state and an accident state based on transformer data Modeling and comparing the fault current waveform from the simulation module, relay waveform signal and the simulation module for simulating the accident of the transformer according to the accident state model may include a determining unit for determining the fault location of the transformer, the present invention A transformer accident determination method according to an embodiment of the simulation module includes the steps of modeling the steady state of the transformer based on the received transformer data, the simulation module modeling the accident state of the transformer based on the steady state model , the simulation module may include the step of simulating the accident of the transformer based on the accident state model, determining the fault location of the transformer by comparing the waveform of the relay and the simulated fault waveform by a determination unit.
