Damping structure and sensitivity in the NORDEL power system

To enhance the inherent damping of power systems due to generators and loads, a variety of stabilizer configurations can be used for the generators, static VAr compensators (SVCs), and high-voltage DC (HVDC) links. How the overall damping matrix is built up from these contributions is studied. This is used to develop a technique for systematic siting of damping equipment in power systems with several poorly damped modes in a given frequency window. This technique is applied to the NORDEL system. Special emphasis is given to handling very large systems, voltage-dependent loads, and alternative measurement schemes.<
