Electric Facilities Design

Course Description

Structure of the electric power system, Classifications, Standards. IEC standards. Equipment definitions and terminology. Design principles. Substation project chronology. Workflow and project sequence. Planning. Engineering design, drawings and documentation (CAD). Construction, testing and commissioning. Costs and Financial Analysis. Schedules and Impacts. Substation Grade Types. Design techniques. Bus configurations, Reliability criteria. Insulation and insulation protection. General specification and ratings of power equipment. Transformers. Circuit breakers. Switches. Disconnectors. Ancillary equipment. Potential and current transformers. Substation auxiliary systems. Grounding. Grounding design considerations.

General Competencies

The course addresses a complete variety of substation design subjects at a level appropriate to those relatively new to the area of substation design. It introduces technical requirements, configuration philosophies, design practices, information sources and work processes.

Learning Outcomes

  1. describe electrical blueprints,
  2. analyze current transformers,
  3. analyze voltage transformers,
  4. analyze substation technical requirements,
  5. choose substation elements (busbar, switching devices, transformers, cables, grounding),
  6. apply knowledge about substation system design.

Forms of Teaching

Lectures

Lectures will be held two hours a week with the use of PowerPoint presentations and overhead projectors.

Seminars

During semester, students will create one seminar.
