This course provides a comprehensive understanding of TG Island Erection, Steam Turbine Commissioning, and Operation. The program begins with the erection of steam turbines, covering foundation centering, leveling, installation of casings, pedestals, rotors, and inner and outer turbine parts. Participants learn radial clearance checks, provisional and final centering, liner installation, and assembly of bearings, couplings, and turning gear, reinforced through a practical case study on TG Island erection. The course further explores steam turbine commissioning and start-up, including pre-checks, Automatic Turbine Runup System (ATRS), synchronization, load raising, frequency control, and safe shutdown procedures. Critical concepts such as plant interlocks, emergency operating conditions, turbine trips, blackout, and house-load operations are addressed to ensure safe and reliable turbine performance. By the end of this course, learners will gain hands-on experience and theoretical knowledge to execute turbine erection, commissioning, and operational procedures efficiently, optimizing performance, ensuring safety, and supporting successful TG Island projects.

Syllabus

Erection Work in TG Island
- This module provides a comprehensive understanding of steam turbine erection activities carried out in the turbine-generator (TG) island during power plant construction. It covers the sequence of turbine erection, including foundation centering, setting of leveling plates and wedges, installation of turbine seating and pedestal plates, erection of HP, IP, and LP turbine casings, rotor installation and provisional centering, radial clearance checks, installation of inner and outer turbine components, final alignment, coupling installation, turning gear installation, and final assembly procedures. The module also includes a practical case study to understand real-world turbine erection practices, quality requirements, and alignment procedures.
Commissioning and Operation of Steam Turbine and its Auxiliary Systems
- This module provides detailed knowledge of steam turbine commissioning procedures, operational sequences, and auxiliary system readiness for safe and efficient power plant operation. It covers the typical power plant project cycle, commissioning philosophy, steam turbine commissioning sequence, pre-startup checks, automatic turbine run-up systems (ATRS), synchronization, initial loading, load raising, frequency control, shutdown procedures, and emergency operating conditions including plant interlocks, blackouts, turbine trips, and house-load operation.
