COURSE OVERVIEW:

The electrical infrastructure of a gas turbine package is a sophisticated network that integrates high-voltage generation with high-speed control logic and auxiliary power. This course provides a comprehensive technical framework for the maintenance and testing of these critical systems, ensuring maximum availability and operational safety of the turbine unit. Participants will explore the complex relationship between mechanical rotation and electrical output, focusing on the specific maintenance needs of the generator and its associated excitation and starting systems.

The scope of this training addresses the practical field skills required to maintain generator windings, brush rigging, and digital control interfaces within the turbine enclosure. It covers the technical nuances of insulation resistance testing, high-potential testing, and the calibration of temperature and vibration sensors that protect the machine. The curriculum provides a detailed focus on the troubleshooting of auxiliary systems, including the DC lube oil pumps, cooling fans, and the critical Black Start diesel interfaces.

Coverage includes the implementation of rigorous testing protocols during planned outages and the interpretation of online monitoring data to predict incipient failures. Attendees will learn to manage the risks associated with high-current electrical faults and the environmental stresses of heat and vibration common in gas turbine environments. By combining theoretical power generation principles with practical maintenance workflows, the course equips professionals with the expertise required to ensure the long-term reliability of gas turbine electrical assets.

COURSE OBJECTIVES:

After completion of this course, the participants will be able to:

• Identify all major electrical components within a gas turbine package.
• Explain the operation of the Load Gearbox and Generator interface.
• Perform detailed inspections of generator stator and rotor windings.
• Execute maintenance on the excitation system and carbon brushes.
• Test and calibrate turbine protection sensors (Speed, Temp, Vibration).
• Maintain the integrity of the Gas Turbine Control System (GTCS) wiring.
• Troubleshoot faults in the Static Starter or Variable Frequency Drive.
• Verify the operation of the DC emergency backup power systems.
• Conduct insulation resistance and polarization index tests on the generator.
• Perform functional testing of the generator circuit breaker and protection.
• Manage the maintenance of cooling systems and heat exchangers.
• Document all maintenance activities and test results for compliance.

TARGET AUDIENCE:

This course is intended for Electrical Maintenance Engineers, Turbine Technicians, Power Plant Operators, and Asset Managers responsible for thermal power generation.

TRAINING COURSE METHODOLOGY:

A highly interactive combination of lectures, discussion sessions, and case studies will be employed to maximize the transfer of information, knowledge, and experience. The course will be intensive, practical, and highly interactive. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share in developing the right answers using their analysis and experience. There will also be some indoor experiential activities to enhance the learning experience. Course material will be provided in PowerPoint, with necessary animations, learning videos, and general discussions.

The course participants shall be evaluated before, during, and at the end of the course.

COURSE CERTIFICATE:

National Consultant Centre for Training LLC (NCC) will issue an Attendance Certificate to all participants completing a minimum of 80% of the total attendance time requirement.
