Abstract

The formulation of a variable structure excitation control system is presented for a synchronous generator at no-load . Factors influencing the design are investigated and properties of the generator  excitation in sliding mode are revealed . It has been verified  thro ugh a digital computer simulation that improved an dynamic performance is obtained. The existence of physical limits in the  generator system degrades the quality of structure excitation characteristics. However, other characteristics are maintained yielding quicker response and reduced sensitivity to parameter changes.
