Underexcitation limiter models for power system stability studies

Underexcitation limiter models suitable for use in large scale power system stability studies are presented. These models are compatible with recommended excitation system models. Using these models, it is expected that most underexcitation limiters in use on large power system-connected synchronous machines can be represented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
