Abstract
Field tests, computer simulation of the field tests, and computation of synchronizing and damping torque coefficients by means of frequency response analysis and modified frequency response analysis were carried out for the Mactaquac hydraulic turbine generators of the New Brunswick Electric Power Commission. The collected data is used to verify that the power stabilizers increase stability of the Mactaquac units, and as a basis for investigation into the methods used to calculate synchronizing and damping torque coefficients. Results indicated that the torque coefficients found by the modified frequency response analysis differ slightly from those obtained by the frequency response analysis, yet values obtained by either method provide a good indication of the dynamic stability of a generator.Keywords
