Abstract

This paper presents a graphical explanation on the damping torque analysis (DTA) method. The explanation is established based on small-signal equal-area criterion of power system stability analysis. From the graphical explanation, a generalized approach for the analysis of damping effectiveness of power system control is proposed. An example is given in the paper to demonstrate how the generalized approach can be used to study the influence of STATCOM (static synchronous compensator) voltage control on the damping of power system oscillation in a multi-machine power system.
