Alinement and Modeling of Hanford Excitation Control for System Damping

The alinement of speed excitation supplementary control for each of the two Hanford 430 MW nuclear steam turbine-generator units was readily accomplished through field testing. Off-line frequency response tests of the supplementary control units, voltage regulators and exciters and frequency and step response test of the excitation system provided data used to develop a dynamic simulation model of the Hanford units. The information will aid computer studies of dynamic performance.
