Power Generation Transmission and Distribution

Introduction

The electrical power system comprises power plants generating power using various types of fuel, and extra-high voltage Transmission network, and high and low voltage distribution systems. With the rapid increase in power demand by various types of power consumers, the power system is expected to provide an uninterrupted power supply in the required quantity and of proper quality to the consumers at minimum cost.

The purpose of this course is to provide information and technical details about the mechanical and electrical equipment used in various types of power plants using different fuels and different prime movers to generate electrical power.

The course also covers the various methodologies adopted for reliable and cost-effective transmission of bulk power from the generating stations to the load centres at extra high voltages over long distances to the receiving stations. The course includes the selection of various methods for reliable distribution of power at high and low voltage from the receiving stations to the load centers in consumer’s premises for reliable supply at the lowest cost with due consideration to design, operation, and maintenance of equipment in power generation, transmission and distribution system. The course gives emphasis on practical applications and modern technologies adopted in present-day power generation, transmission, and distribution systems.

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?

This course is designed for anyone responsible for the design, operation, protection, repair, and maintenance of electrical power systems and equipment in power plants, transmission systems, and power distribution systems. The course would also be useful to those electrical engineers who are planning new electrical installations and augmentation/ modification of existing power distribution systems in view of plant expansion, to know about the state of the art, cost-effective methodologies for generation, transmission, and distribution of power.
