Electro-MEchanical Reciprocating GEnerator
This project has received funding fromWave Energy Scotland as part of stage 3for Power Take-Off projects
• Objective:
“This project will allow developing engineering solutions for survivability in the marine environment and give valuable information concerning the EMG performance in real sea conditions”Budget: circa £2.5m• Timeline: 2017 – 2019
• Partners:
HardWare-In-the-Loop Testing• Location: Doosan Babcock, Glasgow, Scotland• Environment: dry and flooded• Control system: displacement/force/speed control• Input: SIMULINK simulations• Peak Mechanical Power: 100 kWp

Hard-Ware-In-the-Loop Testing• Results:
• Irregular wave tests:• Able to provide a reaction force proportional to speed under irregular conditions
• Constant speed tests:• Average efficiency 75% - 85% (mechanical input -> EMG -> AC electrical output)
• Load tests:• Tested force load: 215 kN
