Adaptive SVC damping controller design, using residue method in a multi-machine system

摘要

In this paper the design of an adaptive Power Oscillation Damping (POD) controller has been investigated for a Static Var Compensator (SVC). Simultaneous linearization of power system is carried out through a Recursive Least Squares (RLS) identification algorithm, after which a residue method is applied for adaptive POD parameter tuning. Proposed methodology has been simulated on a four machine test system considering current injection model for SVC. Obtained results through this approach demonstrate that this adaptive POD gives more appropriate performance in comparison with fixed parameter controller in a wide range of operating conditions.
