DFWind 2 research project

Project title: DFWind Phase 2 – German Research Platform for Wind Energy

Summary:

The overall project objective is to upgrade the DFWind research test field, which is currently being implemented, to create an infrastructure for wind energy research that is unique in the world. This includes the extensive instrumentation of two research wind turbines of the current multi-MW class as well as several specially designed wind measurement masts for the fully comprehensive recording of ambient and operating conditions. With this research platform, on the one hand, novel components and concepts can be tested on the overall system and, on the other hand, industrially suitable models for the description of large wind turbines can be derived,
validated and improved.

Content and Methodology:

The specific contributions in this subproject focus on the one hand on the detailed characterization of the flow and operating conditions and on the other hand on the preparation of research on innovative concepts for monitoring and controlling the plants as well as the plant network. Specific objectives are the characterization of the wind field in front of, in and behind the rotor plane by means of short-range lidar systems on the ground and in the spinner of the wind turbine as well as the preparation of safe testing of experimental control systems of the single turbine as well as of the turbine network on the wind turbines in the test field.

WindIO research project

Project title: WindIO – Concept and construction of a cyber-physical system for the holistic development of wind turbines.

Summary:

The overall goal of the WindIO joint project is to build a cyber-physical system based on a digital twin of the research wind turbines in operation, to create standardized interfaces for holistic configuration management, and thus to generate the urgently needed data-based development tool for the further development of wind energy technology. By continuously feeding real, but also already interlinked, virtual sensor data from the running operation and the real environmental, wind and weather data in real time, the acquisition of a precise actual state of the plant and its components is to be ensured. A reciprocal data flow results in a continuous alignment between physical and virtual WT, so that both systems can be further developed in equal measure and the accuracy of forecasts or the informative value of simulations will increase significantly as a result.

Content and Methodology:

The technical focus of the University of Bremen is on the design and construction of the information technology system, consisting of sensors, signal transmission and data processing for continuous recording of the plant status, detailed modeling and simulation, and the construction of the core functions for information and platform management. The goal is to develop a formal overarching information modeling framework for WEA-specific Digital Twins that is capable of integrating different knowledge domains and existing taxonomies and standards. Possibilities for coupling measurement data and virtual data (such as analysis or simulation results) in a comprehensive information structure are evaluated and implemented.

HiPE-WiND research project

Project title: HiPE-WiND – Multidimensional loads on the high-performance electronics of wind turbines

Summary:

The aim of the project is to investigate the high-performance electronics for wind turbines under real multimodal environmental and load conditions, to research their causes of failure and to develop and experimentally verify concepts for optimizing their robustness. This requires extensive experimental investigations in which entire inverter systems are reproducibly exposed to multimodal loads. The aim of these investigations is to obtain indications of weak points in the system hardware through accelerated ageing and to analyze how inverter service life can be optimized by specifically influencing the electrical loads.
