Generator Excitation Systems Training Course

Introduction

This Generator Excitation Systems training course has been developed for the participants to learn new skills associated with Generator systems and refresh their previous skills and training, to further advancement of knowledge. The successful operation of any Generating Systems ultimately depends on how well the inspection, testing, maintenance and troubleshooting functions are carried out. Well-developed procedures and planning will in the long run result in reduced costs, equipment down time, parts requirements and troubleshooting complexity.

This training course will highlight:

• Power Generator Systems
• Excitation Modes and Characteristics
• Voltage Control and Governors
• Generator Transformers
• Synchronization Techniques
• Generator Circuit Breakers
• Common Generator Faults
• Maintenance and Online Monitoring of Alternators

Objectives

At the end of this Generator Excitation Systems training course, you will learn to:

• Elaborate on different types of power system generation
• Discuss operations of the steam and gas turbines
• Examine different types excitation systems
• Explore different types of switch gear associated with generator systems
• Identify automatic voltage regulating techniques and governors
• Describe troubleshooting techniques and online monitoring

Training Methodology

In this Generator Excitation Systems training course, each participant will receive an electronic copy of the comprehensive course notes. The presenter will outline and discuss the topics using computer displays and videos. This training course is designed to have an interactive format to maximize delegate participation. Questions and answers are encouraged throughout and at the daily sessions. Case studies and examples will be discussed in problem solving workshop sessions. This gives participants the opportunity to discuss with other delegates and the presenter their specific problems and appropriate solutions. Only minimum note taking is encouraged to ensure maximum delegate attention during this training course.
