Abstract :
In this paper a scanning tool based on the normal form technique is developed for the investigation of nonlinear modal behavior of AC/DC power systems with DC power modulation. The AC-DC interface variables are solved by symbolic calculation software MAPLE. A state space model is then formed for normal form method with second order approximation. A 4-generator AC/DC power system is studied with different fault locations and various input signals for DC power modulation
