PROJECT SCOPE
1. Comprehensive Generator Disassembly
The scope of work included the disassembly of casings, auxiliary systems, and all technological connections, providing safe access to the generator’s critical internal components.
The operation was carried out in stages, in full compliance with strict occupational health and safety procedures and technical documentation.
2. Shaft Line Works
The scope of work included the disassembly of the shafts connecting the integrated gas and steam turbine sections.
Ensuring subsequent coaxial alignment of such a complex system was one of the most challenging aspects of the project.
3. Rotor Replacement and Balancing
As part of the modernization, a new generator rotor was installed, followed by dynamic balancing of the entire assembly.
This process was critical for eliminating vibrations and ensuring stable operation at full rotational speed.
4. Cooling System Refurbishment and Leak Test
The generator cooling system was refurbished, followed by a leak test.
The positive test results confirmed the correctness of the executed works and the system’s readiness for operation.
Final Outcome
The works were completed with full success.
The generator equipped with the new rotor successfully passed load and dynamic tests, achieving operating parameters in full compliance with the manufacturer’s specifications.
