Emergency Diesel Generator Operation, Maintenance and Troubleshooting Course

Course Overview:

This course combines diesel power plants with its structure, how it works and how to efficiently construct it for the best use. Participants will know how to select the best diesel engine for power supply, how to select fuel injection system and various parameters including but not limited to external conditions and fuel used for affecting generator output.

The course further covers safety measures within installation, operation and maintenance of the power supply. Other topics such as common problems and their solution, period maintenance and storage of the engine will be part of the course modules as well. 

This course would be perfect for engineers, supervisors, technicians and operators who want to get practical exposure and knowledge to ensure that diesel power generators are working in an efficient and reliable manner.

Course Objectives:

By the end of the training, participants will be able to:

• List and interpret the basic terminology related to electric power generation
• Outline the advantages of using diesel engines for power generation
• Describe the layout, construction, and the principle of diesel engine power generation unit
• Explain how to select a diesel engine for power back-up
• Outline the characteristics and design features of diesel engines
• Explain the operation principle of various types of fuel injection systems used on diesel engines
• Describe how air charging into diesel engines done and how fuel injected.
• Outline the basic safety measures in installing, operating, and maintaining the diesel engine power generators
• List the factors that affect the output of diesel generator set
• Describe how diesel generators are prepared for storage
• Outline the periodic maintenance operations for diesel generators
