Substations – Volume VI – Voltage Regulators and Capacitors - a PDH Online Course for Engineers, Architects and Surveyors

Substations – Volume VI – Voltage Regulators and Capacitors

Course Outline

The first chapter of this course reviews voltage regulators including specifications, ratings and application issues related to regulators. The second chapter covers capacitors including different methods to bank capacitors and the methods to switch capacitor banks.

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

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 volume of the series on Substation Design has focused on voltage regulators and capacitors. Voltage regulators provide the very important function of maintaining the desired delivery voltage from a substation. With the proper use of the control settings and line drop compensation, regulators can correct for load variations as well. A properly applied and controlled voltage regulator not only keeps the voltage at a customer’s service entrance within approved limits but also minimizes the range of voltage swing between light and heavy load periods.

Shunt capacitor banks can be used at substations to improve power factor and voltage conditions by supplying leading kilovars to transmission and distribution systems.
