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. Learning objectives Upon completion of this course, the participants: know the function of a MEGADRIVE LCI know the different modes of operation are able to operate and maintain a MEGADRIVE LCI are able to localise faults and replace defective parts Participants Operating personnel Maintenance personnel Prerequisites Basic electrotechnical knowledge Basic knowledge of synchronous machines Personal computers knowledge is recommended Topics Power electronics in general The function of rectifiers and converters Static Frequency Converter Principal function Configuration for various applications Regulation circuits Characteristic curves Limitations, monitoring and protection Operation Operating modes Annunciation Safety in relation to MEGADRIVE LCI Documentation Project documentation How to read the Hardware schematics Hardware components Functions, settings Interfaces to peripherals Water cooling / Air cooling Maintenance and Trouble shooting Replacement of Thyristors Software tools: - LCI Control Terminal - (Transient Recorder) Test programs Methods Lectures and demonstrations Practical exercises inclusive hands-on training using a LCI-model Factory tour Duration 4 days Number of participants: Max. 8 On site course on request Course description G820 Medium Voltage Drives MEGADRIVE LCI with AC 800PEC Operation and Maintenance Course outline Day 1 Course overview Basic LCI-Theorie - overview - rectifier - mode of operation - blockdiagram - on/off sequences - protection Characteristic curves Day 2 Day 3 Operator Training - Converter - Safety - Operation - Fault handling Maintenance Training (cont.) - Preventive maintenance - Corrective maintenance User’s manual operation Overview Hadrware component - signal flow - setting Maintenance Training - Safety instruction - Converter overview - Documentation - How to read hardware drawing Factory tour ABB Switzerland Ltd.
