Quasi-Stationary Modeling and Simulation of Electrical Circuits using Complex Phasors

This paper presents how complex phasors are used for quasi-stationary analysis of electrical circuits, i.e. with sinusoidal excitation neglecting dynamic tran-sients. The theoretical background of complex phasors is elaborated and a Modelica implementation – the AC Library – is presented. Additional exam-ples demonstrate the possibilities of the application of complex phasors
