Development Process

1 Market Study
The development process is based on market studies, which serve to clarify various questions such as specific customer requests, type of WEC, technology and climatic conditions.

2 Simulation and Load Calculation
The WEC is modeled on the computer with rotor blades, drive system and the entire control system, then subjected to the anticipated winds. If the WEC is to be located offshore, wave action is also simulated. The results of the simulation are the mechanical loads, which are used as the basis for WEC design and control parameters.

3 Design, Calculation and FEM Analysis
We use 3D programs to design the individual WEC components. The large castings are calculated with finite elements and then analyzed and optimized for extreme and fatigue loads. Mechanical parts such as gear teeth and screwed joints, as well as components like the tower and enclosures are calculated analytically. The next step is to design the cooling, lubrication, and sensor systems.

4 Power Engineering and Testing
Planning the power engineering covers everything from the generator to grid connection. The frequency converter plays a key role, as it adjusts the variable speed of the WEC to the constant grid frequency. At our power testing station in Klagenfurt we test the generators with the converter system at variable speed and power up to 5 MW at 50 Hz or 60 Hz.

5 Automation Engineering
Our automation engineers plan the sensors and actuators for each individual assembly, including the control concept. These components are all integrated in the WEC's safety system. We then draw the circuit diagrams for the entire WEC with connections to our central control system. The control cabinets for the turbine are then built, tested and optimized here in Klagenfurt.

6 Software
Our system management software starts the WEC, measures the wind speed and connects the converter to the grid. The entire control system with blade pitch control is operated using this software. Visualization systems show the key data for the turbine and link up the individual WECs in wind parks. We optimize WEC startup using data from database systems. Plans can also be drawn up for electricity generation and maintenance work.

7 Factory Testing
When the entire nacelle with the hub has been set up at the customer's premises testing begins. A typical configuration involves assembling two systems and connecting them to the hub with one simulating the wind. This means that all the assemblies are tested at full power on the ground before final installation.

8 Erection and Commissioning
Once we have completed testing, the WEC is erected under the supervision of our experts. Depending on the turbine size, the largest cranes in the world may be used. When all the controllers have been correctly set, the WEC undergoes testing again to determine the actual loads and verify the design. Finally we hand over the documentation to the customer.

9 Service and Supply Chain Management
We focus on our customers' success as our common goal. With the support of our service and supply chain team, customers have the expertise to optimize turbines for local conditions, develop a local supply chain and use our components in their own WECs. As a result, our customers are ready to build their first WECs within 8-12 months. The service department also offers customer training courses, promotes cooperation with local universities and helps customers to expand.
