Results of subsynchronous resonance test at Mohave

The results of the subsynchronous resonance test conducted on the number 2 turbine-generator at the Southern California Edison Company Mohave Generating Station are presented and discussed. Comparisons are made between measured and calculated torsional natural frequencies and mode shapes, and the damping associated with each torsional mode stimulated is presented at various loads. In addition, the methods of stimulating the mechanical torsionals of the turbine-generator set are discussed along with a description of the instrumention system that was used to obtain the data.
