High and Medium Voltage Substation Design, Testing and Maintenance

Introduction

Substations play an important role in a power system network in maintaining the continuity of power supply and power quality to the industrial and commercial consumers. The high voltage substation comprises switching equipment, transformers, reactors, var compensators, protection, control, automation, and communication. A properly planned and designed substation is essential for the reliable operation of the power system network.

This course covers all aspects of high and medium voltage substation design including regulatory and environmental requirements, general design considerations, application of switching and power equipment, fault calculations, safe grounding design, protection/control, automation and communication, and maintenance considerations.

Objectives

    To provide a practical understanding of planning, design, application, and maintenance aspects of high and medium voltage substations for utility networks and industrial plants.

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?

Electrical power generation systems and distribution engineers in utilities and industrial plants, managers of private electricity producers and large power consumers, substation engineers, consulting engineers, manufacturers of power equipment, technicians and technologists and other technical personnel involved in the design, operation and maintenance of high/medium voltage substations.
