Abstract
This paper focuses on the simulation of unbalanced voltage dips in a large transmission system. The theoretical background about symmetrical components and the impedance matrix is presented. Equations for during fault voltage are derived. Simulations of balanced and unbalanced dips are performed in a large transmission system taking into account the transformer effect. Results are presented in several ways including graphs and tables.
