Description
Summary:Torsional interaction between non-identical generating units with a coincident torsional mode is investigated. The generators are electrically identical but have differences in their mechanical parameters. The mechanical system of each generator in the two-machine model is represented by the modal model; this enables independent variation of mode damping, inertia and frequency which is not possible to achieve with the conventional spring-mass representation.
