Comparison of power system stabilizers for damping local mode oscillations

The Bureau of Reclamation has examined the damping of local mode oscillations using three types of power system stabilizers (PSS): internal frequency; electrical power; and accelerating power. Comparisons of operating characteristics such as PSS output noise and sensitivity to load changes are also included. Results are based on the analysis of field test data and analog computer simulation, Methods that can be used at remote sites during PSS alignment tests have been employed.<
