Three-winding transformer ring-bus characteristics

SUCH hydroelectric projects as the Boulder Dam, Grand Coulee, and that proposed for the St. Lawrence River present serious power limit and short-circuit problems. Each of these developments will be capable of producing over 1,000,000 kw, part of which for each case must be transmitted over 200 miles. Any method which will increase transient stability and lower fault currents should be carefully investigated; this paper presents the investigation of such a method.
