Fundamentals of Substations for Non-Engineers, September 14-15, 2020 in Denver, CO

Transmission to distribution substation designs vary in complexity, proportional to their rating (MVA) and application. A variety of engineering disciplines are involved including civil, mechanical, electrical power and communications. Design philosophies are influenced by a utility’s contingency strategy, space limitations, aesthetic requirements, work rules, maintenance practices, and other factors.

This course will provide an overview of design methods with given specifications and a one-line diagram for a typical T to D substation. Discussion concerning substation device options provide attendees with the information to make intelligent choices regarding design features. The class creates a forum for comparing best practices for substation design, maintenance, and the operation of these facilities.

Learning Outcomes   

A comprehensive introduction to the following substation components will be discussed:

  • Review the various types of substations
  • List substation reliability/redundancy considerations
  • Review substation specifications and one-line diagrams
  • Review site selection criteria and components
  • Determine the keys to initial substation layouts  
  • Get an overview on civil engineering considerations including: concrete foundations, steel structures, and liquid containment
  • Review substation components and ratings including: power transformers, voltage regulators, voltage regulating controls, overcurrent protective devices of fuses and circuit breakers, overvoltage protection  
  • List the purposes, uses for and types of protection & control
  • Get introduced to metal enclosed substations
