The CL-Windcon project has recently celebrated its third General Assembly Meeting in Pamplona, hosted by CENER (National Renewable Energy Centre of Spain). During the event, the partners have showcased the main advances of this European project, focused on a new way of approaching the design and operation of a wind farm, based on the wind farm closed loop control paradigm.

Representatives of the 15 organisations which conform the consortium have taken part in this encounter: General Electric, Ramboll, University of Stuttgart, Technical University of Munich and UL International GmbH / DEWI from Germany; Enel Green Power and Politecnico di Milano from Italy; Aalborg University from Denmark; Delft University of Technology and the the Energy research Center of the Netherlands (ECN part of TNO), Garrad Hassan from the United Kingdom, as well as the Spain´s entities Ikerlan-IK4, Qi Europe, ZABALA Innovation Consulting and CENER as project coordinator. Throughout two days, the most important milestones of the project were shared and discussed.

CL-Windcon is funded by the Framework Programme for Research and Innovation Horizon 2020 of the European Union (agreement nº 727477) and will last until October 2019. The initiative has a total cost of 4.9 M€. The CL-Windcon project is fully aligned with the objectives of the Energy Transition and policies to face the climate change challenge driven by the European Union.

Up to this moment, CL-Windcon project has performed developments over wind farm models, which now conform a set of multi-fidelity tools of wide application to wind farm control design and validation.

Furthermore, because additional cyclic loads are generated when the blades of a wind turbine enter into an upwind turbine wake, CL-Windcon has developed (i) estimators for partial wake overlap detection to be used for triggering countermeasures for reducing wake-generated loads, (ii) a novel closed-loop wake steering methodology, as well as (iii) an individual triggerable pitch control. Additionally, reliability enhancing techniques for management of sensor failure based on sensor redundancy have been proposed for generator speed measurements.

Moreover, validation activities for the turbine control strategies and supporting technologies developed in CL-Windcon have been made. Apart from simulation analyses, three wind tunnel testing campaigns have been performed so far and the fourth one is expected to take place in the following weeks. Instrumentation at the full-scale wind farm has taken place, too.

Finally, the activities for the feasibility assessment of the proposed technologies has already started setting the basis for the common approach. This will allow a sound analysis under different perspectives such as O&M, technology at turbine and farm level, redesign, Life Cycle Cost (LCC), Life Cycle Assessment (LCA) and LCoE evaluations, or wind power standards.

The CL-Windcon project includes other transversal activities focused on the dissemination and communication activities and the exploitation of results. The main goal of such activities is to spread the word about the project among the stakeholders of the wind energy sector, policy makers and the general public. The exploitation of results strategy aims to bring to the market the main applications of the project for the sector.

The next steps of the project will be the classification of models and generation of wind farm control, the implementation of high fidelity simulations, the preparation of the wind field experiments, follow up with wind tunnel campaigns and the advance on the feasibility studies. All the progress will be reviewed in next general assembly meeting to be hosted by Polimi at Milano next October 2018.

On the 20th of December the Tågeröd wind farm in Sweden started to generate electricity, supplying clean power to the local grid. H&M group’s decision has made Tågeröd possible – using a new and innovative additionality solution. The Swedish design group has contributed to the construction of four new wind turbines, providing top-financing through the purchase of ECOHZ GO2. GO2 is a renewable energy product that combines the purchase of documented renewable power with the financing and building of new renewable power capacity.

ECOHZ GO2 is based on renewable electricity purchases documented with Guarantees of Origin (GO). The result is that 18 GWh clean, renewable power is generated annually, and in the excess of 240 GWh new power by the end of 2030.

The real innovation is linked to the GO2 financing model which enables, within two to four years, the top-finance loan to be recirculated and finance yet another power plant of similar size. By 2030, H&M group’s single decision will have resulted in another eight wind turbines to be top-financed and built. In total, these power plants will generate 439 GWh by 2030.

“We use electricity from renewable energy sources to reduce our carbon footprint. We have been looking for ways that our renewable electricity procurement could more clearly contribute to the building of more renewable capacity, while still being easy to implement. GO² ticks those boxes, and we’re assessing its role in our future procurement strategy”, says Anna Gedda, Head of Sustainability, H&M group. “We are working to achieve 100% renewable electricity for all our operations, and we are currently at 96%. This is part of our larger commitment to maximize the use of renewable and sustainable energy throughout our supply chain.”

“Adding new renewable energy sources was previously only possible through more complex investments in on-site power projects. Tågeröd is an example of how companies can consume and contribute to renewable energy production without committing to major infrastructure investments. The world will need more renewable energy in the future and business leadership, like H&M has shown, is essential to make this happen,” says Tom Lindberg, Managing Director at ECOHZ.

The H&M group is one of 119 influential companies that have joined the collaborative, global RE100 initiative and committed to using 100% renewable power in all their operations – across all territories. ECOHZ GO² is a solution to help RE100 members and other forward-looking companies achieve their goals and “go one step further”.

“It is great to see companies innovate and experiment with new ways to meet their public commitments to renewable electricity where Power Purchase Agreements or other long-term commitments may not currently be a viable option. By working with ECOHZ, H&M has found a flexible solution that helps to grow the local market for renewables, while enabling the company to show leadership as it edges ever closer to its RE100 goal,” says Constant Alarcon, RE100 Campaign Manager at The Climate Group.

Following the integration of 3D printing as part of its digital services portfolio, Siemens has achieved an industry breakthrough with the first successful commercial installation and continuing safe operation of a 3D-printed part in a nuclear power plant. Because of the stringent safety and reliability requirements in the nuclear sector, achieving this qualification is a significant accomplishment.

The replacement part produced for the Krško nuclear power plant in Slovenia is a metallic, 108mm diameter impeller for a fire protection pump that is in constant rotating operation. The water pump provides pressure for the fire protection system at the plant. The original impeller was in operation since the plant was commissioned in 1981; its original manufacturer is no longer in business. Obsolete, non-OEM parts are particularly well-suited for this new technology as they and their designs are virtually impossible to obtain. This technology thus allows mature operating plants to continue operating and achieving or, as in the Krško case, even extending, their full life expectancy.

 

Siemens’ team of experts in Slovenia reverse-engineered and created a “digital twin” of the part. The company’s additive manufacturing (AM) facility in Finspång, Sweden, then applied its advanced AM process using a 3D printer to produce the part.

Meeting the Krško NPP’s stringent quality and safety assurance requirements required extensive testing that was performed jointly with the Krško operations team over several months, ensuring that the new 3D-printed part would perform safely and reliably. Further material testing at an independent institute as well as a CT scan, showed that the material properties of the 3D-printed part were superior to those of the original part.

The Krško plant is among the highest-ranked of European nuclear power plants by the European Nuclear Safety Regulators Group in terms of safety according to assessments following Fukushima. It provides more than one-quarter of Slovenia’s and 15 percent of Croatia’s power, making it vitally important to the region. For over a decade, Siemens has been actively performing modifications and providing service on the plant’s non-nuclear side, including turbine, generator and auxiliary equipment.

Siemens operates a state-of-the-art AM production facility in Finspång where is has been advancing this technology since 2009. Siemens extensively uses AM for rapid prototyping and has introduced serial production solutions for rapid manufacturing of small fuel mixers and for rapid repair of burner tips for mid-size gas turbines. The first 3D-printed burner component for a Siemens heavy-duty gas turbine has been in successful commercial operation in a power plant in Brno, Czech Republic, since June 2016. It has achieved 1,600 equivalent operating hours without causing any forced outages. For parts production in industrial gas turbines, the benefits of Siemens’ AM include an approximate 50 % reduction in lead time and a 75 % reduction in development time. Siemens recently announced it has finished its first full load engine tests for gas turbine blades completely produced using AM technology.

At 11.6 metres long, 4.5 metres wide and almost 8 metres high, the dimensions of each of the four Bosch boilers for the new Ledvice power plant unit of the energy company CˇEZ are impressive. In total, the boilers produce up to 167 t/h of superheated steam for the start-up process of the new steam turbine that generates power. However, the Ledvice power plant does not just supply power: it also provides heating to some 300 companies and 20,000 residents. The huge boilers provide additional supply during peak load periods and serve as a backup for the district heating network.

The Ledvice power plant is situated in the Czech Republic in the foothills of the Erz Mountains between the cities of Teplice and Bilina. This new power plant unit, with its formidable electrical power output of 660 MW, is owned by the utility CˇEZ and has recently come online at this site.

In its role as general contractor, the company Skoda Praha Invest was responsible for implementing the new turnkey power plant unit and the steam boiler system. Stringent safety requirements and a tight time schedule demanded a high degree of flexibility and experience from all those involved in the project. Read more…

Turboden, a group company of Mitsubishi Heavy Industries (MHI), leader in Organic Rankine Cycle (ORC) turbogenerators for distributed power generation employing renewable sources and waste heat, signed an order with Acciaieria Arvedi for a new waste heat recovery ORC unit to be installed at the Arvedi Steel Plant in Cremona, Italy. Arvedi Group is one of the leading European steelmaking companies.

The Turboden 100 HR ORC unit, designed for 10 MW nominal capacity and operated at 7.5 MW for the first years, will convert the off-gas waste heat from the steel melting Electric Arc Furnace (EAF) to electric power. The heat recovery system configuration includes a saturated steam heat carrier circuit to convey the heat from the furnace exhaust gas to the ORC unit.

This new system will be coupled to the existing Tenova Consteel® system, which heats and feeds metallic charge to a 250-ton Electric Arc Furnace (EAF), one of the largest in the world, for a combination of heat recovery and environmental sustainability. The heat recovery system will be put in operation at the beginning of 2017.

The waste heat boiler, to be supplied by Tenova, will be installed on the primary EAF off-gas line in parallel to the existing quenching tower and will produce saturated steam.

During the EAF process, the saturated steam (heat carrier) will transfer thermal power to the ORC turbogenerator working fluid, which then expands in the turbine to convert incoming thermal energy into electric power by means of an electric generator.

The main drivers for this project are the energy production valorization, with a consequent reduction in CO2 emissions of approximately 23,300 t/y, and the access to White Certificates.

Minesto has together with German tidal turbine manufacturer Schottel Hydro completed the turbine design of Minesto’s tidal power plant Deep Green. The Swedish marine energy company has now placed an order for a prototype of the turbine, with delivery in early 2017.

The order of the so-called Power Take Off system is the first result of the strategic technology partnership between Minesto and Schottel Hydro, which began in December 2015. During 2016 and 2017, Schottel Hydro will deliver a customised turbine solution which will optimally fit the requirements of Deep Green, Minesto’s tidal power plant.

Compared with the first generation Deep Green, the turbine’s performance has been improved by about 10 percent. The development of the turbine has, among other things, resulted in a larger rotor diameter. The rotor now has five blades instead of three. The design has been established anddeepgreenpartswi1 verified through model tests by German Schiffbau Versuchsanstalt in Potsdam.

The model scale tests prove the turbines performance and cavitation behavior to be advantageous compared to previous designs.

The development of Deep Green now enters the next phase where the design of the full-scale system will be completed. At Schottel Hydro the manufacturing of the prototype and the factory acceptance test will be tackled.

In parallel with the final design Minesto will procure subsystems and components which will be assembled into a first full-scale demonstrator. It will then undergo final functionality testing. After that, Deep Green will be implemented in full scale on the offshore facility in Wales during 2017.
