Abstract :
According to Hurwitz´s criterion, this paper deduces the steady state borderline of steam turbine with AVR on the map of reactive capability curves, using the mathematical model of one machine infinite bus system. It extends steam turbine´s safe range under exciting operation compared to generator without AVR, and presents a proposal for the reactive power service market.
