This paper presents a kind of optimum modeling method to apply the optimum theory to the research on torsional vibration of a large turbine-generator shafts system. By this method, the simulating labratory set of torsional vibration of large tubine-generator shaft systems can be optimized and the torsional behavior of the simulating laboratory set is consistent with that of real turbinegenerator units. In the paper, the simulating laboratory set of torsional vibration for turbine-generator shafts system of Koeberg Power Station in South Africa is optimized. The optimized laboratory set is compared with that introduced in reference [1], which shows the optimized laboratory set is better than that in reference [1] in providing the natural and dynamic behavior of the torsional vibration of the tubine-generator unit.
