Abstract :
St. Clair curve provides a simple means for estimating power transfer capabilities of transmission lines. It concerns three limiting factors: thermal limit, voltage quality (or drop) limit, and angular stability limit. This paper illustrates the influence of voltage stability limit and presents an extended loadability curve. Moreover, the impacts of line resistance and shunt compensation on line loadability are investigated.
