Electric Generators: Operation, Performance Analysis, and Testing

Introduction

Maximum efficiency, reliability, and longevity of electrical power generator such as the various types of generators and excitation systems and voltage control. These objectives can only be achieved by understanding the characteristics, selection criteria, common problems and repair techniques, preventive and predictive maintenance. This course is a must for anyone who is involved in the selection, applications, or maintenance and operation of electrical generator. It provides the latest in technology. The course covers how these generators operate and provide guidelines and rules that must be followed for a successful operation.

Objectives

    Upon the successful completion of this course, each participant will be able to:-

    • Describe how generator functions
    • Describe active and reactive power
    • Describe the major components used in the construction of an AC generator
    • Explain the operation and maintenance of the most common excitation systems
    • Explain how a speed governor alters generator output in response to a frequency deviation
    • Explain how the voltage regulator alters generator output in response to a voltage deviation
    • Discuss the causes and effects of both voltage and frequency oscillations and the impact they each have on power system dynamics
    • Discuss abnormal generator operation and recommended actions for generator protection.
    • Describe the various repair methods for defective component condition
    • Describe the procedures for the various generator tests and the safety precautions for the conducting of these electrical tests.

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.

Who Should Attend?

Managers, engineers, and technicians, responsible for the design, installation, testing machines, and maintenance and operation of electrical substations and power stations, who require to refresh their knowledge and skills in working with circuit breakers at high voltage levels.
