Abstract
A new type of series compensation for the improvement of the dynamic stability of an excitation control system has been successfully developed and tested. The device serves to compensate for the adverse effects of the underdamped complex poles which, mathematically, characterize the dynamic behavior of a synchronous machine operating at high loading and high torque angle. Results of factory tests described in this paper and field tests described in a companion paper confirm that the compensation is very effective in extending the operating stability limits of a generator; stable operation at torque angles greater than 110°has been achieved.Keywords
