In this paper, power system electromagnetic and electromechanical transient hybrid real-time simulation technology is expounded in details, which has advantages of the electromagnetic transient simulation program and electromechanical one. The more details needed to analyze the dynamic characteristics of power systems are provided by this hybrid simulation technology, and the scale of power system...
To investigate the Very Fast Transient Over-voltage (VFTO) distribution in transformer windings in Gas Insulated Substation (GIS), a systematic methodology based on hybrid model is presented for establishing high-frequency model of transformer windings in this paper. Firstly, the voltages at the end of each coil are calculated by means of Single-Conductor Transmission Line Model (STLM). Secondly,...
