Research on Transformer Fault Simulation Using DTS

Based on the actual production, this paper analyzes the problem that the other main transformer is overloaded after the fault trip of one main transformer is set in the dispatcher simulation training system (DTS). Based on the analysis of the fault, the countermeasures to quickly deal with serious overload of the main transformer are analyzed, and the treatment methods to effectively avoid the to the five-level power grid events are proposed as well as the summary and reflection on the accident. At the same time, the fault really recreates the real scene of overload of the main transformer during the summer peak, which provides a valuable idea for the dispatcher to deal with the accident quickly.
