Substations – Volume VIII – Site and Foundation Design - a PDH Online Course for Engineers, Architects and Surveyors

Substations – Volume VIII – Site and Foundation Design

Course Outline

The course has three chapters. Chapter one covers site design including layout, roads, soil bearing pressure, and drainage issues. Chapter two is an in-depth look at the different types of substation foundations used and how to calculate design loads on a foundation. Chapter three is a brief overview of the design factors for control houses.

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

Intended Audience

This course is intended for electrical engineers and others who want to understand how electric power substations are designed.

Benefit to Attendees

This series of courses is a step by step overview of the factors that need to be considered when building an electrical substation. The course will give the reader a good understanding of the factors involved in the design of a substation.

Course Introduction

This course is one of a series of thirteen courses on the design of electrical substations. The courses do not necessarily have to be taken in order and, for the most part, are stand-alone courses. The following is a brief description of each course.

Volume I, Design Parameters. Covers the general design considerations, documents and drawings related to designing a substation.

Volume II, Physical Layout. Covers the layout considerations, bus configurations, and electrical clearances.

Volume III, Conductors and Bus Design. Covers bare conductors, rigid and strain bus design.

Volume IV, Power Transformers. Covers the application and relevant specifications related to power transformers and mobile transformers.

Volume V, Circuit Interrupting Devices. Covers the specifications and application of power circuit breakers, metal-clad switchgear and electronic reclosers.

Volume VI, Voltage Regulators and Capacitors. Covers the general operation and specification of voltage regulators and capacitors.

Volume VII, Other Major Equipment. Covers switch, arrestor, and instrument transformer specification and application.

Volume VIII, Site and Foundation Design. Covers general issues related to site design, foundation design and control house design.

Volume IX, Substation Structures. Covers the design of bus support structures and connectors.

Volume X, Grounding. Covers the design of the ground grid for safety and proper operation.

Volume XI, Protective Relaying. Covers relay types, schemes, and instrumentation.

Volume XII, Auxiliary Systems. Covers AC & DC systems, automation, and communications.

Volume XIII, Insulated Cable and Raceways. Covers the specifications and application of electrical cable.

Course Summary

This course has covered design factors related to the substation site. The objective of site work design for a substation yard is to provide an easily accessible, dry, maintenance-free area for the installation and operation of electrical substation equipment and structures.

The course also covered the design issues for substation foundations. Foundation design primarily depends on the in-place density and strength/strain properties of the soil on or in which foundations are located. The course reviewed the general considerations for the design and construction of a substation control house.
