COURSE OVERVIEW:

The protection of synchronous generators is one of the most complex areas of power system engineering due to the variety of electrical and mechanical faults that can occur. This course provides a technical deep dive into "Generator Protection Schemes," focusing on the coordination between the prime mover, the excitation system, and the electrical grid. Participants will explore the mechanics of "Differential Protection" and "Reverse Power" logic, learning how to safeguard expensive rotating assets from catastrophic failure without causing nuisance trips during grid transients.

The scope of this training addresses the full range of generator sizes, from small standby units to large utility-scale machines. It covers the technical nuances of "Fault Detection," focusing on "Negative Sequence" current and "Loss of Excitation" (40) logic. The curriculum provides a detailed focus on "Recommended Settings" according to IEEE C37.102, ensuring that participants can configure modern numerical relays to provide sensitive, selective, and fast-acting protection for stator and rotor components.

Coverage includes the implementation of advanced protection such as "100% Stator Earth Fault" using third harmonic injection and "Out-of-Step" protection. Attendees will learn to utilize "Event Records" and "Fault Oscillography" to analyze generator behavior during disturbances. By combining power system theory with practical relay setting methodologies, the course equips professionals with the expertise required to manage the "Protective Perimeter" of the grid's most critical generation assets.

COURSE OBJECTIVES:

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

• Define the unique "Fault Modes" of synchronous generators.
• Identify the IEEE/ANSI device numbers for generator protection (87, 40, 32, etc.).
• Configure "Stator Differential" (87G) for high-speed fault isolation.
• Implement "Reverse Power" (32) protection to prevent motoring.
• Set "Loss of Excitation" (40) protection using impedance (R-X) logic.
• Calculate "Negative Sequence" (46) limits for unbalanced rotor heating.
• Apply "Over-excitation" (24) protection for core preservation.
• Implement "100% Stator Earth Fault" (64G) detection schemes.
• Coordinate "Generator Protection" with the "Step-Up Transformer."
• Analyze "Out-of-Step" (78) conditions during system swings.
• Utilize "Numerical Relays" for generator monitoring and control.
• Interpret "Fault Records" to distinguish between grid and unit faults.

TARGET AUDIENCE:

This course is intended for Protection Engineers, Power Plant Managers, Commissioning Technicians, and Electrical Operations Staff.

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.
