ABSTRACT: In this paper, a simpler and more accurate method is proposed to estimate torsional
torque history in turbo-generator shafts in real time due to Subsynchronous Oscillation (SSO) in power
systems. The response torsional torque history in each weak cross section is obtained by the measured ...
