MEGADRIVE LCI

Course description
G820 Medium Voltage Drives
MEGADRIVE LCI with AC 800PEC
Operation and Maintenance
Course goal
Load Commutated Inverters (MEGADRIVE LCI) or in
other terms Static Frequency Converters (SFC) are
used together with large synchronous motors as an
adjustable speed drive or to start large gas turbines
without high inrush current on the power supply. These
systems are available in a power range from 1MW up to
100MW.
The course goal is to teach students to operate,
maintain and troubleshoot a MEGADRIVE LCI
controlled by AC 800PEC.
