Dynamic Modeling and Simulation of Deep Geothermal Electric Submersible Pumping Systems

Deep geothermal energy systems employ electric submersible pumps (ESPs) in order to lift geothermal fluid from the production well to the surface. However, rough downhole conditions and high flow rates impose heavy strain on the components, leading to frequent failures of the pump system. The downhole sensor data is limited and often unreliable.

Our team from the research area "Mechatronic and renewable Energy Systems" has developed a detailed and dynamical model system which serves as basis for deeper understanding and analysis of the overall system behavior. Furthermore, it allows to design model-based condition monitoring and fault detection systems, and to improve controls leading to a more robust and efficient operation.
