A Utility Perspective on Under-Excitation Limiters
نویسنده
چکیده
-This paper presents a brief review of the experience and perspective of a large Canadian utility with Under Excitation Limiters (UELs). The purpose of the UEL is reviewed along with the results of field testing and modelling. It is concluded that users of these devices must define the dynamic performance requirements of the limiters, by examining the purpose of their installation, and then setting and testing them accordingly. Keywords--excitation systems, underexcitation limiters, stability.

Generator Over Excitation Capability and Excitation System Limiters
Sometimes, power system events have shown the need for generators to operate in the overexcited region to support stable operation. Operation up to, and transiently beyond, the overexcited limits from the capability curve is sometimes required. The two main issues in the paper are the generator capability in this region and the design of OEL (OverExcitation Limiters) in the excitation system th...
