Dynamic Stability Tests on a 733 MVA Generator at Kincaid Station

Abstract

Field tests have confirmed that properly designed excitation control can extend the dynamic stablity range of machines. A new type of stability compensation, described in a companion paper, has been successfully applied. Application of this new equipment is made possible by the installation of a modern solid state high performance excitation system. Field tests conducted on a 733 mVA generator have shown that this compensation, applied to the excitation system, is effective in extending the stability limit of the machine beyond the limit obtainable without compensation.
