At the IALB of the University of Bremen, there are various possibilities for detailed investigations of wind turbines, both simulator-based and on the test rig and in the open field. The institute has several wind turbines of the type Krogmann 15\/50, which already have all the functional characteristics of a “large” wind turbine at a rated power of only 50 kW. On such “small” plants, modifications and adaptations are possible with a reasonable effort.<\/p>\n

In the Bremen Industrial Park, the ForWind Institute BIMAQ (Bremen Institute for Measurement, Automation and Quality Science) and Deutsche WindGuard GmbH from Varel operate the 180 meter high research wind turbine “UNI Bremen”. Systematic investigations are being carried out on the 3.4-megawatt plant to develop and test practicable solutions in plant technology. It is intended to provide measurement data for improvements in the design, material selection, manufacturing and control of wind turbines.<\/p>\n

A detailed simulation model of a Krogmann 15\/50 was created in order to be able to estimate expected loads or the effects of new control and regulation processes before they are used on the test rig or in the open field.<\/p>\n
Here, the method of multi-body simulation in combination with a detailed model setup can provide valuable information on the dynamic design and optimization of the overall system.<\/p>\n
A possible multi-body representation of the power train includes individual components such as rotor, gearbox, shaft, generator, etc. as concentrated masses. These are connected to each other and to the housing via spring \/ damper elements that map the axial torsional and bending stiffnesses. Likewise, the rotor blades and the tower can be simulated as elastic elements.<\/p>\n
The model makes it possible to realistically simulate the aerodynamic effects of turbulent wind or gusts, for example, and thus to determine the mechanical loads to be expected in the drive train as well as those on the nacelle and tower.<\/p>\n

In the ERDF-funded cooperation project “Krogital – Digital Cloud-Twin Krogmann 15\/50 in Bremen\/Bremerhaven<\/em>“, the two institutions of the University of Bremen (Bremer Centrum f\u00fcr Mechatronik [BCM]<\/a> and Bremer Institut f\u00fcr Integrierte Produktentwicklung [BIK]) together with partners have achieved the goal of digitizing a wind turbine (WTG) operated by the BCM member institute for electrical drives, power electronics and components [IALB] by installing a comprehensive sensor system. For this purpose, it was necessary to continuously record high-frequency measurement data from operations. After the wind turbines were equipped with modern sensor technology by BCM and BIK, the data was merged and transferred to the cloud for further intelligent processing. For this hardware interface, BCM built a data logger and deployed it on the WTG.<\/p>\n [\/et_pb_accordion_item][et_pb_accordion_item title=”WindIO” _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}” open=”off”]<\/p>\n <\/p>\n This project is about unlocking new potential for yield management and accelerating the pace of innovation in wind energy. Within the scope of the joint project “WIND IO”, a cyber-physical system (CPS) of a wind turbine in operation is being built. Suitable interfaces for a holistic configuration management and thus a standardized data-based development tool for wind energy technology will be created.<\/p>\n <\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n [\/et_pb_accordion_item][\/et_pb_accordion][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ admin_label=”Team Section 4″ _builder_version=”4.20.2″ _module_preset=”db886634-b884-4b0c-b416-76c49aaf13bc” background_color=”#022869″ background_enable_image=”off” global_colors_info=”{}”][et_pb_row _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.20.2″ _module_preset=”default” global_colors_info=”{}”][et_pb_text admin_label=”About Us” _builder_version=”4.22.1″ _module_preset=”default” header_font=”||||||||” header_font_size=”60px” header_2_font_size=”40px” header_3_font_size=”40px” header_4_font_size=”30px” header_5_font_size=”24px” header_6_text_color=”#f2f2f2″ header_6_font_size=”20px” text_orientation=”center” background_layout=”dark” header_font_size_tablet=”50px” header_font_size_phone=”40px” header_font_size_last_edited=”on|phone” header_2_font_size_tablet=”36px” header_2_font_size_phone=”32px” header_2_font_size_last_edited=”on|phone” header_3_font_size_tablet=”36px” header_3_font_size_phone=”32px” header_3_font_size_last_edited=”on|phone” header_4_font_size_tablet=”26px” header_4_font_size_phone=”22px” header_4_font_size_last_edited=”on|phone” header_5_font_size_tablet=”22px” header_5_font_size_phone=”20px” header_5_font_size_last_edited=”on|phone” header_6_font_size_tablet=”18px” header_6_font_size_phone=”16px” header_6_font_size_last_edited=”on|tablet” locked=”off” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_4,1_4,1_4,1_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”1_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.22.1″ _module_preset=”default” header_3_text_align=”center” header_3_text_color=”#FFFFFF” link_option_url=”https:\/\/www.brementestturbine.science\/” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.22.1″ _module_preset=”default” header_3_text_align=”center” header_3_text_color=”#FFFFFF” link_option_url=”https:\/\/www.uni-bremen.de\/produktentwicklung\/institut” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.22.1″ _module_preset=”default” header_3_text_align=”center” header_3_text_color=”#FFFFFF” link_option_url=”https:\/\/www.bimaq.de\/” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][\/et_pb_column][et_pb_column type=”1_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.22.1″ _module_preset=”default” header_3_text_align=”center” header_3_text_color=”#FFFFFF” link_option_url=”https:\/\/www.uni-bremen.de\/ialb\/ialb” global_colors_info=”{}”]<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":" Institute for Electrical Drives, Power Electronics and DevicesSimulation models and digital twins At the IALB of the University of Bremen, there are various possibilities for detailed investigations of wind turbines, both simulator-based and on the test rig and in the open field.
