Wind Turbine Mechanical Systems

WTT 120W

Course Description

Prerequisites: Prerequisites: MT 151 and MT 161 each with a grade of "C" or better: Identifies and explains the operation and construction of wind turbine mechanical systems.

Explains preventative maintenance activities and lubrication requirements while emphasizing potential mechanical failures that are associated with the maintenance activities. Provides opportunities to inspect, disassemble, and reassemble wind turbine mechanical systems. Demonstrates proper lubrication and preventative maintenance techniques along with applicable mechanical repair procedures. (30-15)

Outcomes and Objectives

Identify wind turbine gearboxes and other mechanical systems.

Objectives:

  • Demonstrate an understanding of the operation of various gearboxes (helical, spur, and worm-wheel) and state typical faults and their symptoms.
  • Demonstrate an understanding of the operation of variable speed drives.

Demonstrate an understanding of preventative maintenance activities of wind turbine mechanical systems.

Objectives:

  • Explain preventative maintenance.
  • Explain mechanical repair procedures.
