Description
MEGATROL combines the variable speed drive MEGADRIVE and UNITROL 6800 excitation system of a gasturbine power generating group. It starts the gasturbine with its frequency converter part and controls the generator voltage after the machine group reach its rated speed. Its design is based on ABB’s high performance controller family AC 800PEC.
Objectives
The course goal is to teach students to start-up, adjust, operate, maintain and troubleshoot the MEGATROL system.
Upon completion of this course, the students:
• know the function of a gasturbine starter as part of MEGATROL?
• know the different modes of the start up sequence
• are able to operate and maintain the MEGATROL?
• Remembers the synchronous machine and its various operating conditions at rated speed
• Know the principle operation of the excitation system
• Are familiar with the principle function of the electronic devices
• Can read and interpret the hardware drawing
• Are able to operate the voltage regulator using the excitation control terminal as well as the Control Terminal of the drive part
• Can explain the most important software functions
• Are able to localize and replace defective components
