Transient electromagnetic states: Simulation

Numerical methods can be used to simulate electromagnetic transients in power systems. They focus on the automatic formulation of power system equation systems and on generic solution methods.

This article is intended as a reference document on the calculation methods applied in modern software. It covers the entire subject, including the calculation of multiphase power flow, steady-state initialization methods and the solution of transient power system differential algebraic equations.

Practical applications of simulation methods and notions of electromagnetic transients are presented in the article "Transient regimes in power systems" [D 82] .

Readers unfamiliar with the study of power systems in general may wish to consult the articles "Interconnection and transmission systems: operation" [D 4 091] and "Power system dynamic simulation tools" [D 4 120] .

For fundamental theories, definitions and methods of power system analysis, the reader is referred to "Linear power systems. Definitions, principles, methods" [D 60] , "General theorems and quadripoles" [D 62] and "Three-phase systems"
