COURSE OVERVIEW:

Power generators are the heart of the electrical system, converting mechanical energy into the stable electrical power required by modern society. This advanced course delves into the complex electromagnetic, thermal, and mechanical systems that constitute a large synchronous generator. Participants will explore the intricate design of rotors and stators, focusing on how these components handle extreme centrifugal forces and thermal expansion while maintaining high efficiency and precise voltage control.

The scope of this program encompasses the entire generation suite, including excitation systems, cooling mechanisms, and lubricating oil systems. It addresses the technical challenges of maintaining hydrogen-cooled and water-cooled stators, as well as the nuances of brushless excitation and static converters. The course provides an in-depth look at operational limits, such as the generator capability curve, and how modern control systems manage reactive power, frequency regulation, and synchronization to the grid in both utility and captive power environments.

Coverage includes advanced diagnostic and maintenance techniques designed to extend the life of these high-value assets. Attendees will learn to conduct and interpret EL CID (Electromagnetic Core Imperfection Detection) tests, wedge tightness surveys, and partial discharge measurements. The curriculum emphasizes a proactive maintenance philosophy, teaching participants how to identify early signs of winding degradation, core vibration, and bearing wear. By combining theoretical knowledge with practical troubleshooting skills, the course prepares professionals to maximize generator availability and prevent catastrophic failures.

COURSE OBJECTIVES:

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

• Analyze the electromagnetic principles of synchronous generator operation.
• Interpret the generator capability curve to ensure safe loading limits.
• Manage complex cooling systems, including Hydrogen and deionized water.
• Evaluate the condition of stator winding insulation using Tan-Delta testing.
• Troubleshoot failures in brushless and static excitation systems.
• Perform precision alignment and vibration analysis of the rotor assembly.
• Interpret Partial Discharge (PD) data to identify insulation aging.
• Conduct Electromagnetic Core Imperfection Detection (EL CID) inspections.
• Implement effective maintenance strategies for bearing and lubrication systems.
• Analyze the impact of unbalanced loads and harmonics on rotor heating.
• Execute safe synchronization procedures and manage load rejection events.
• Develop a comprehensive long-term maintenance plan based on RCM principles.

TARGET AUDIENCE:

This course is designed for Power Plant Engineers, Senior Technicians, Operations Managers, and Maintenance Specialists working in thermal, gas, hydro, or nuclear power facilities.

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.
