Simulation Analysis of Transformer Short Circuit Fault

Abstract

Power transformers are one of the main equipment in power production, with high cost and long manufacturing time. If a fault occurs during the power supply process, it will prevent the normal operation of the power system and result in no electricity available to power users. One of the main factors affecting the safe operation of transformers is short circuit fault, and short circuit faults at the outlet of substations or in close proximity can also pose a serious threat to transformers. This article simulates transformer short-circuit faults and establishes a simulation model using MATLAB/simulink to verify the harm caused by transformer short-circuit. Verification has shown that short circuit faults pose significant risks.
