Excitation systems directly affect power system stability where generators are large, connected with long lines, at sensitive voltage locations, or in systems with local or intertie oscillations. Electric Research staff has extensive experience in the adjustment of excitation systems and related power system stabilizers for high-initial response excitation or for the older Amplidyne, Magastat, and other similar systems. Excitation system analysis may include field tests of existing systems, recommendations for modification of alignment, assistance in alignment, development of stability study constants from field measurements, and a study of special problems.

Electric Research staff has in depth experience in the theoretical and operational requirements of automatic generation control. Electric Research also has the capability to test, align, design, and model existing and proposed systems. Electric Research can adjust filters, power plant allocators, generator allocators, and constraint limiters.

Special controller problems can be analyzed, algorithm modifications suggested, and recommendations made for alignment of governing systems to work effectively with automatic generation controls.
