Development of Scott Transformer Model in Electromagnetic Transients Programs for Real-Time Simulations

This paper presents a Scott transformer model to be applied in electromagnetic transients (EMT) programs, particularly the absence of detailed for performing real-time simulations (RTS). Regarding transformer, common topology converting three-phase network into two single-phase networks, EMT programs is essential simulate large-scale electric railway systems. A code-based has been developed RTS directly and contain transformer’s actual impedance characteristics. By establishing mathematical foundation with current injection method, we presented matrix representation conjunction solution programs. The proposed can handle more practical parameters transformers relatively low computational load. Thus, it supports flexible computation simulators finite number processor units. accuracy verified by simulating comparing simulation results an industrial certified performance. Furthermore, case study involving comparison field measurement data Korean system demonstrated efficacy model.
