초록

Since large gas turbines used for power generation are operated in conjunction with the power grid, the operation stability is very important, so it must be fully verified from the design stage to the completion of production. The rotor of the gas turbine is difficult to analyze because it is assembled by fastening dozens of disks using tie rods, unlike the rotors of general rotary machines or steam turbines. DHI(Doosan Heavy Industries) is developing a large-scale 270 MW gas turbine(DGT-300H S1) for power generation. In this process, the rotor dynamic design consistency from the scale model to the actual rotor is reviewed in advance in order to improve the rotor dynamic analysis and design consistency. The final design and fabrication have been completed and the assembly is in progress. In this paper, the progress and verification results have been mentioned based on the final results of the development process.
