Engineering Services

| In general: In addition to licensing or technology transfer for complete wind turbines, we offer comprehensive, detailed calculations, software, design, validation, and verification of individual components or systems. Upon request, we also prepare studies on various drivetrain concepts, generator-converter systems, or other auxiliary systems.

And: We also offer technical modifications to adapt to specific site conditions (e.g., earthquakes, typhoons, hot climates). The portfolio also includes load flow calculations and simulations of turbine behavior during grid faults. W2E also reviews third-party designs and prepares reports, strength analyses, or load calculations. Naturally, all work is strictly confidential.

CAD icon

2D/3D CAD Design

| We now have over 25 years of experience in the mechanical analysis and design of wind turbines with various drive concepts and tower types:
  • 2D/3D CAD design of the entire wind turbine (rotor, nacelle, tower, and foundation), including the creation of drawings and specifications
  • Tower design (tubular tower, lattice tower, concrete steel hybrid tower, and tubular steel lattice hybrid tower)
  • Customized designs and enhancements for hot and cold climates, high winds, earthquakes, and dusty regions
  • Design of assembly and transport tools as well as lifting and repair tools

Load calculation icon

Load Calculation, Measurement, and Verification

| Wind turbines are designed based on their structural behavior in combination with the highly dynamic loads caused by environmental conditions. The load calculations are based on the DNVGL guideline and the IEC 61400-1 standard to meet the requirements of renowned certification bodies.

Dynamic load calculations are performed using Alaska/Wind, MSC.Adams, and FLEX5. FLEX5 was developed at DTU Copenhagen and is continuously refined by W2E. In combination with its in-house post-processing tool FLEXAnim, W2E is able to create a basic wind turbine design in a very short time. For advanced dynamic simulations, W2E uses the universal multi-body programs Alaska from Chemnitz University of Technology and MSC.Adams from MSC.Software. MSC.Adams has been extended with aerodynamic loads using AeroDyn v14.0 from NREL. Both multibody programs have been enhanced with C++ and Fortran90 user interfaces to establish a connection with the original control software.

Load measurements on the wind turbine prototypes are performed in accordance with the IEC 61400-13 standard. The load calculations using Alaska/Wind, MSC.Adams, and FLEX5 were verified using real measurement data from a 2.0-MW wind turbine prototype. In addition, a multibody-based hardware-in-the-loop test bench was set up to verify the original control hardware.

FEM icon

FEM and Structural Optimization

| We apply the finite element method (FEM) in accordance with applicable guidelines for the design and optimization of all relevant wind turbine components, including castings, welded structures, and composite materials. To ensure realistic boundary conditions, the interaction of the analyzed component with the surrounding structure is taken into account.

Using the MSC.Marc software, all types of nonlinear effects such as contact surfaces, material effects, and clearance can be accounted for. Particular attention is paid to the modeling of bolted joints and bearings, taking into account the internal bearing design, contact angle, operating clearance, roller and raceway profiles, load distribution between the rolling elements, and temperature effects.

Control icon

Design of Wind Turbine Control Software

| We now have 25 years of experience in developing efficient control software for wind turbines. And we are constantly refining our software, including for future-oriented, innovative control systems. All parameters used in the control software are the result of an optimization process carried out for various operating points.

Here, we work closely with the renowned Institute for Automation Technology at RWTH Aachen University in Germany. The results of this research are gradually integrated into the classic control software and tested in practice on W2E prototypes.

The application software is designed for various hardware platforms: M1 (Bachmann), WP4x00 (Mita-Teknik), and I/O Field Controller 750 (WAGO). The software architecture is based on standardized languages: instruction list, function block diagram, sequential function chart, and structured text (IEC 61131). C and C++ code ...

Safety icon

Our Safety System

| The safety system for wind turbines serves to protect personnel and prevent machine failures, particularly through hazard analysis and risk assessment (in accordance with the European Machinery Directive 2006/42/EC). Safety functions are defined in accordance with EN ISO 13849-1 and validated in accordance with EN ISO 13849-2. In addition, we implement sensors, a logic unit, and actuators to prevent serious hazards such as overspeed and exceeding vibration limits in accordance with Performance Level D.

Additional safety functions address cable twists (cable loops), short circuits, emergency stop, transformer protection, and control system failure. We use safety switching devices from Pilz, Bachmann, SIEMENS, and Mita-Teknik and also offer comprehensive solutions for fire detection and (optionally deployable) automatic fire extinguishing systems, as well as measures such as residual current monitoring, earth fault detection, arc detection, and correctly designed TN-S or IT network structures.

Noise icon

Experimental Studies on Noise and Vibrations

| We now have extensive experience in the structural dynamics of large mechanical structures such as wind turbines, ships, and offshore installations. These structures can be analyzed with regard to their modal and forced vibration behavior in order to subsequently optimize the structure or the control system of the wind turbine. In this context, noise generation is also investigated and reduced.

The following investigations can be carried out - often using our own measuring equipment - in the field of experimental structural dynamics:
  • Application of classical and operational modal analysis to all wind turbine structures (nacelle, tower, rotor blade)
  • Analysis of tonalities and their reduction
  • Sound path analysis
  • Application of vibration dampers
  • Design of methods for noise-reduced operation
  • Optimization of wind turbine control for vibration reduction

eModelling icon

Modeling and Simulation of Electrical Characteristics

| The desired grid behavior plays a key role in the overall design of our systems to ensure a stable grid connection. To this end, the entire drivetrain, the pitch system, the converter (DFIG or full converter with PMG), and the wind farm are modeled. The control algorithms of the submodels are 100% identical to those installed in the wind turbine.

Grid connection behavior is simulated using PowerFactory or PSCAD software. In addition, we perform load flow calculations and dynamic simulations of individual turbines as well as entire wind farms (steady-state current, voltage, power, power factor). We also analyze various grid fault conditions (3-phase short circuit, 2-phase short circuit, LVRT, HVRT).

Together with our partners at the University of Rostock, Chair of Power Electronics and Electric Drives and the RKL Competence in Power Electronics, we are researching methods and procedures for grid-forming wind turbines. The focus is on control and system concepts that will enable wind turbines to perform grid-supporting functions in the future and actively contribute to the stability and resilience of electrical power systems. The goal of our work is to establish the technical foundations for the provision of system services within the framework of new grid connection guidelines.

Grid icon

Electrical Engineering

| The generation, conversion, and distribution of electrical energy, as well as the electrical auxiliary and control equipment, are indispensable components of modern multi-megawatt wind turbines. The electrical design is based on the DNVGL guideline as well as European and IEC standards to ensure the reliable operation of all electrical systems.

We provide detailed specifications for the generator, transformer, pitch system, azimuth system, control cabinet (including circuit diagrams), inverters, tower equipment, and cables, which we tailor to specific customer requirements or environmental conditions. In doing so, we either work closely with internationally established suppliers and/or qualify new ones on-site as needed.

We account for various types of interfaces. To this end, various fieldbuses are configured: Profibus, CANopen, Profinet, Modbus, Ethernet, etc., including calculation, specification, installation, cable list, cable routing diagram, and the definition of cable harnesses and connectors.

Multibody icon

Multi-body simulation

| Multi-body simulation is the most powerful dynamic simulation tool for complete mechatronic systems. General multi-body simulation tools such as MSC. Adams and Alaska offer the ability to simulate any dynamic system, including force, damper, and actuator elements, as well as the integration of automation and control routines. In addition, there are predefined interfaces to MATLAB/Simulink for the development and testing of control algorithms using a realistic control path.

We have extensive experience in multibody simulation in the fields of wind energy and aircraft construction, particularly through close collaboration with the Chair of Technical Dynamics at the University of Rostock.
