A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels.

Substations may be owned and operated by an electrical utility, or may be owned by a large industrial or commercial customer. Generally substations are unattended, relying on SCADA for remote supervision and control.

This course provides an overview of substation design, equipment, functionality and applications. The course is applicable to engineers of all disciplines.

Learning Objectives

Upon completion of this course, participants will be able to:

• Distinguish the functions of substations with sufficient accuracy to distinguish it from related concepts.
• Determine the important substation equipment with sufficient accuracy to distinguish it from related concepts.
• Analyze how power reaches area stations and the differences among transmission, switching, and area stations, citing the distinguishing characteristics relevant to engineering decisions.
• Identify the layout of a typical (13/4-kV) unit substation and demonstrate understanding through an assessment question or scenario.
• Evaluate the types of switching devices used in substations in a representative engineering or safety scenario.
• List common types of power transformers with sufficient accuracy to distinguish them from related concepts.
• Recognize the types of cooling systems used in transformers with sufficient accuracy to distinguish them from related concepts.
• Estimate the basic transformer design calculations using course principles and given data.
• Assess the purpose of a phase angle regulator (PAR) in substation design in a representative engineering or safety scenario.
• Summarize transformer auxiliary devices and demonstrate understanding through an assessment question or scenario.
• Classify series and shunt reactors, citing the distinguishing characteristics relevant to engineering decisions.
• Develop an understanding of how SCADA systems are used in substations for control and monitoring in a representative engineering or safety scenario.
• Select A/C, lighting,and power systems for substation auxiliary equipment with sufficient accuracy to distinguish them from related concepts.
• Choose an appropriate substation bus design in a representative engineering or safety scenario.

Certificate of Completion

You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 20 questions. CPD credits are not awarded until the course is completed and quiz is passed.
