Overcoming Failures of Rotor Pole Connections at Buchanan Dam

摘要

After rewinding two generators at its 49.1-MW Buchanan Dam on the Lower Colorado River in Texas, the Lower Colorado River Authority experienced several unit trips. These trips were caused by failure of the rotor inter-pole connections on the generators. The rewind contractor developed a unique flexible inter-pole connection design that solved the problem and allowed reliable operation of the units.
