Electromagnetic Transients (EMT)
PowerFactory provides an EMT simulation kernel for solving power system transient problems such as lightning, switching and temporary over-voltages, inrush currents, ferro-resonance effects or sub-synchronous resonance problems. Together with a comprehensive model library and a graphical, user-definable modelling system (DSL), it provides an extremely flexible and powerful platform for solving power system electromagnetic transient problems.
