COURSE OVERVIEW:

The excitation system is the heart of a synchronous generator, dictating its ability to maintain voltage stability and share reactive power within a grid. This course provides a high-level technical deep dive into the engineering principles of excitation, ranging from basic DC machines to modern digital static exciters. Participants will explore the control logic that governs field current and learn how these systems respond to transient load changes and grid disturbances.

The scope of this training addresses the full lifecycle of an excitation system, including the design parameters for various machine sizes and the rigorous process of commissioning a new installation. It covers the technical nuances of PID tuning, Power System Stabilizers (PSS), and the implementation of limiters to protect the generator from thermal stress. The curriculum provides a detailed focus on the integration of digital Automatic Voltage Regulators (AVR) and their communication with centralized SCADA systems.

Coverage includes the implementation of advanced troubleshooting techniques to identify faults in power electronics, rotating rectifiers, and sensing circuits. Attendees will learn to interpret excitation waveforms and utilize diagnostic software to optimize system performance. By combining control theory with practical field engineering, the course equips professionals with the expertise required to manage excitation systems that ensure the stability and reliability of the modern power network.

COURSE OBJECTIVES:

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

• Define the primary functions of an excitation system in power generation.
• Differentiate between Brushless, Static, and DC excitation architectures.
• Analyze the components of a digital Automatic Voltage Regulator (AVR).
• Design an excitation system based on generator capability curves.
• Execute a comprehensive commissioning plan for a new excitation unit.
• Perform PID tuning of the voltage control loop for optimal response.
• Configure Power System Stabilizers (PSS) to mitigate oscillations.
• Set and verify Over-Excitation and Under-Excitation Limiters.
• Troubleshoot faults in thyristor bridges and rotating rectifiers.
• Identify the root causes of voltage instability and hunting.
• Utilize diagnostic software for real-time excitation monitoring.
• Ensure compliance with grid code requirements for voltage control.

TARGET AUDIENCE:

This course is intended for Protection and Control Engineers, Commissioning Engineers, Power Plant Managers, and Senior Maintenance Technicians.

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.
