Modeling and Simulation on Transformer Computer Protection in Wind Farm

Abstract:

This paper studies a single machine infinite bus system with two-winding transformer and access 110KV power system after improveing voltage. We established a system model of transformer based on MATLAB/Simulink, and established the computer protection data acquisition system model in wind farm, studied second harmonic ratio brake differential protection. Setted calculation combined with actual differential protection for a given parameter transformer, and use the simulink to simulate test of short-circuit. By the simulation study, we investigated the performance of transformer differential protection.
