Course Description

Introduces generator paralleling and load sharing. Includes the use of multiple generators in grid supply and peak shaving. Covers different switchgear systems utilized in generator control systems. Prerequisites/concurrent: EPG 107.

Intended Outcomes for the course

Upon completion of the course students should be able to:

  1. Couple two or more generators together to supply a given load.
  2. Operate and troubleshoot multiple types of switching gear.
  3. Calculate generator system sizing as needed for a given system.
  4. Adjust engine governors, voltage regulators and related safety components in a multiple generator supply system.
  5. Identify and diagnose problems on generator units using service literature, test equipment, and troubleshooting steps.
  6. Determine the root cause of common system failures.
  7. Connect load banks and verify system response times and outputs.

Course Activities and Design

  1. Size generator systems based on load calculations.
  2. Use software to design generator control system schematics.
  3. Learn how to parallel two or more generators to supply power to a given load.
  4. Troubleshoot system failures and repair them.
  5. Use loadbanks to set up multiple generator systems.
  6. Diagnose and repair multiple types of switchgear.

Course Content (Themes, Concepts, Issues and Skills)

Develop skills to disassemble, inspect and reassemble Generators and related switchgear as they relate to parallel/load sharing operations.

  • Learn governor setup and operation related to paralleling.

  • Learn the use of tools necessary to diagnose and repair load imbalance and stability.

  • Learn the relationship between load types and how they affect load sharing.

  • Learn to diagnose, repair and program multiple brands of electronic engines.

  • Learn to use various electronic tooling and software.

  • Learn to use service literature to diagnose and repair generators and switchgear.

Develop skills in voltage regulation and  failure diagnosis.

  • Learn to recognize failures and their causes.

  • Learn the resources available to the technician for research and failure identification.

  • Learn to properly evaluate a failure and find the reason for the failure.

Practice personal safety.

  • Learn and practice personal safety by wearing Personal Protective Equipment (PPE).

  • Learn and practice shop cleanliness.

  • Learn and practice tool maintenance and safety.

This course will build on the knowledge and skills in the diesel tech program and EPG Classes To successfully parallel generators together to supply power to off grid systems and provide generator systems for grid peak shaving operations. Develop the skills to determine different types of loads that need to be powered and their effects on load-sharing. Develop the knowledge required to operate and troubleshoot multiple switchgear types used in multiple generator set systems. This course will also introduce students to schematic design and use as it pertains to generator control systems design.
