Heidenheim/Oslo, 08-Nov-2016 — /EuropaWire/ — Norwegian energy supplier Sira-Kvina kraftselskap DA awarded the main contract for the upgrade of the control systems at its Tonstad and Solhom hydroelectric power stations with an estimated total project volume of 320 million Norwegian Krones to Voith Hydro AS. Preparatory works began immediately after contract signing in June. With both upgrades Sira-Kvina kraftselskap DA invests in significant improvements to both personnel safety and operational reliability, and also secures the production of clean, renewable energy for another 40 years. Sira-Kvina kraftselskap DA is owned by Lyse Produksjon AS, Statkraft Energi AS, Skagerak Kraft AS and Agder Energi Vannkraft AS. It has a total installed capacity of 1,760 MW and an average yearly production of 6,300 GWh from seven power plants. The awarded contract includes upgrading and modernizing of the control systems and the electrical auxiliary systems for its two hydropower plants Tonstad and Solhom, where old relay control systems will be upgraded to state-of-the-art Programmable Logic Controller (PLC)-based ones. In addition to the control systems for the power units there are also protection and control systems for complex medium- and extra high-voltage systems. Voith has delivered many similar systems all over Norway and is currently also managing the electrical installations at Lyse’s new power station in Lysebotn. The Tonstad power plant is Norway’s largest when it comes to average annual production (3,800 GWh). It therefore plays an important role in Norway’s energy supply and was integrated to the energy grid already in 1968. The incremental commissioning of the upgraded technology will take place annually, starting in spring 2017 with auxiliary systems of Tonstad. Afterwards the new control systems for all five units will be commissioned from 2018 to 2022. Works at the Solhom hydropower plant will run partly parallel when auxiliary systems will be commissioned in 2019 and new control systems for the units follow in 2020 and 2021. The Solhom power plant has an average annual production of 695 GWh generated by two Francis turbines. Together Tonstad and Solhom cover the energy demand of roughly 230,000 households. “This is a really exciting and demanding project. There are several technical challenges and we always have to consider that the other units in the power plant will be in full operation during the modernization. However, thanks to our experience and close collaboration with the customer, our highly dedicated team will be able to successfully complete the project within the scheduled time period,” says Torgeir Myrvold, Project Manager for Tonstad and Solhom. Voith Hydro AS CEO Frode Moen complements: “We are very satisfied being awarded this prestigious project by Sira-Kvina. It is among the largest stand-alone automation contracts awarded within the Norwegian hydropower market.” Hydropower is the largest, oldest and also most reliable form of renewable energy generation. Worldwide it makes an indispensable contribution to stable power supplies and hence to economic and social development – both in industrial countries and in emerging markets. At the same time, hydropower significantly contributes to climate-protecting energy generation. Voith has been a leading supplier of this technology since the early beginning, and continuously develops it further. Voith sets standards in the markets for energy, oil & gas, paper, raw materials, transport & automotive. Founded in 1867, Voith employs around 20,000 people, generates €4.3 billion in sales, operates in over 60 countries around the world and is one of the largest family-owned companies in Europe.* *Without the discontinued Group Division Voith Industrial Services

• Operating result in the core business increased by 18 percent York, Pa./Heidenheim, Germany (December 13, 2016) – In the 2015/16 fiscal year, the Voith Group successfully completed the transformation of the Group, which has taken several years. In 2017, Voith moves into its 150th anniversary year with renewed strength and at the same time anticipated to be starting point of a new period of growth for the Group. In the past 2015/16 fiscal year (ending September 30, 2016), Voith not only significantly improved the operating performance of its Group Divisions but, with the help of its Voith 150+ success program, also generated a clearly positive net result for the Group once again, as forecasted. Parallel to the strong improvement in profitability in all Group Divisions, in addition, Voith has consistently driven forward its strategic focus on its technology and engineering competence in the digital age. As part of this strategy, the Group sold its majority shareholding in the technical services provider Voith Industrial Services. Furthermore, the new Voith Digital Solutions Group Division, in which the company brings together its activities in the fields of IT, automation, software and sensor technology, has commenced operations and has already launched a large number of promising new digital initiatives. Within the next two fiscal years, about €100 million will be invested in development of digital products in the new division. “We have not only made more rapid progress in 2016 with Voith 150+ than expected and have once again significantly improved our net result under challenging macroeconomic conditions – we also set a decisive new course towards making Voith a key digital industry player,” explains Hubert Lienhard, President & CEO. DIGITALIZATION AS A GROWTH DRIVER Following on the previous years marked by realignment activities and re-structuring, Voith is now on a good footing for future growth. In the three traditional Group Divisions – Voith Hydro, Voith Paper and Voith Turbo – the plans are to secure this growth by means of targeted refinement of the existing market and technology leadership. One important growth driver over the coming years will be the new Voith Digital Solutions Group Division that was launched on April 1, 2016. With this Group Division, Voith takes three strategic directions: first, supplementing our existing product portfolio with additional, digital capabilities that offer customers extended functions and added value; second, developing new digital solutions in the traditional core markets; and third, developing new products and business models for markets to date not covered by Voith. The activities brought together at Voith Digital Solutions provide for sales of just under €400 million already in the current year, of which about €320 million was generated by external customers and by 1,500 employees in more than 60 countries. More than twenty solid incubation projects have been taken to alpha or beta stage, some of which are about to be launched on the market. In the next two fiscal years alone, Voith will invest about €100 million in further development of digital products. In addition to the positive effects from the transformation of the Group, the planned sale of its KUKA shareholding will provide Voith with the additional financial headroom for its growth strategy. The transaction is expected to lead to an inflow of €1.15 billion in spring 2017. The proceeds will be dedicated completely to the refinement of the Group’s portfolio, for example accelerating the building up of digital business models. The funds can be used either to facilitate organic growth or to make attractive acquisitions. “As an established technology leader with extensive domain knowledge, we will play a major role in shaping the digital transformation of the industry. We are taking Voith to the next level in its development and are setting out on the next 150 years in the company’s history,” says Lienhard. OPERATING RESULT IN THE CORE BUSINESS INCREASES BY 18 PERCENT In the past fiscal year, Voith further strengthened its base and achieved all key targets – despite economic growth being weak once again, an ongoing subdued investment climate in important customer industries and increasing competitive pressure. All key earnings indicators have been significantly improved due to the Voith 150+ success program increasingly developing its full impact, among other factors. All three of the traditional Group Divisions succeeded in boosting their operating results, with Voith Paper standing out with an increase of 33 percent. In total, the profits from operations of Voith Hydro, Voith Paper and Voith Turbo grew by just under one fifth (18 percent) to €295 million; the operating return on sales in the core business saw a correspondingly rise from 5.8 percent to 7.0 percent. At the level of the holding company, this positive development was counterbalanced to a certain extent by valuation effects on some foreign currency items as well as the costs for setting up the new Voith Digital Solutions Group Division. The Voith Group’s profit from operations was slightly up from the previous year as announced, reaching €275 million (2015: €270 million). The Group’s net result, which had fallen to minus €93 million in the previous year as a result of restructuring costs, improved by €122 million to €29 million in the year under review. This means that this figure was once again positive, as forecasted. Without non-recurring expenses (mainly from impairment losses disclosed on the face of the balance sheet), the net result would have come to as much as €125 million. The orders received in the Group’s continuing operations stood at a good level again in 2015/16. However, due to lower investments in the raw materials market, and in the oil & gas market as well as in the rail sector in particular in China, this figure saw a slight decline of, all in all, around 6 percent to €4.11 billion (2015: €4.39 billion). In contrast, sales remained virtually unchanged at €4.25 billion in comparison to the previous year (€4.30 billion). Orders received and sales were both impacted by negative currency effects. POSITIVE DEVELOPMENT IN ALL GROUP DIVISIONS All three traditional Group Divisions contributed to the positive development of the Group. Voith Hydro looks back on a good fiscal year. Forecasts were exceeded with regard to sales and orders received as well as in profit from operations. This development was sustained in particular by the service business and equipment for and the modernization of hydropower plants. At Voith Paper, the rewards of the consistent restructuring measures performed in recent years are becoming ever more apparent. In a market environment that was difficult at times and did not revive until the second half of the year, sales fell slightly. Yet the Group Division succeed-ed in significantly improving its profitability further. Voith Turbo faced a lower level of orders received and sales in a very difficult market environment – demand was weak on account of the macroeconomic situation especially in the oil & gas business, in mining and the steel industry as well as in the rail sector in particular in China. Strengthened by the efficiency programs implemented in recent years and in the absence of the non-recurring effects seen in the previous year, the net result was, however, clearly increased by 25 percent. OUTLOOK: PROFITABLE GROWTH IN THE ANNIVERSARY YEAR For the current 2016/17 fiscal year, Voith anticipates the state of the global economy to remain fragile. Nevertheless, the company intends to continue with its own positive development. In the operating business, the focus is on profitable growth. To this end, the successful 150+ excellence program will be continued in all areas of the company (from 2017: Voith 150+ Next Level). In doing so, Voith anticipates being able to slightly improve on the annual savings of €250 million communicated one year ago. One other growth driver is the continuation of the digital transformation of the entire portfolio of products and services – with the expansion of Voith Digital Solutions as a central task. In recent years, Voith has formed the basis for future growth with the sale of the Industrial Services Group Division, the establishment of the new Voith Digital Solutions Group Division and the introduction of a leaner, more centralized administration. The new strategic program, Voith 150+ Next Level, will be rolled out in the 2017 anniversary year and will ensure the Group’s intended growth. The Group expects the effects of the new program to become apparent in the coming years. For the 2016/17 fiscal year, Voith anticipates sales around the same level as in the previous year and a slightly increasing level of orders received in comparison to 2015/16. On aggregate, the profits from operations of the Voith Hydro, Voith Paper and Voith Turbo Group Divisions will rise. This profitable core business will enable Voith to shoulder the high development costs for the new Voith Digital Solutions Group Division from current operations. The Group’s profit from operations will therefore also be clearly positive, yet probably slightly lower on account of these costs. The Group’s net result will be clearly positive once again – even without the expected strong non-recurring effect from the sale of the KUKA shareholding. “We are now starting out on the next 150 years of the company’s history – by marrying the long-term perspective of a family-owned business with the dynamics and innovative strength of the digital world. This is precisely what is expressed by our new positioning and the new claim ‘Inspiring Technology for Generations’. Voith is ready to meet the future,” summarizes President & CEO Lienhard. ABOUT VOITH For 150 years, Voith’s technologies have been inspiring customers, business partners and employees worldwide. Founded in 1867, Voith today has around 19,000 employees, sales of $4.7 billion and locations in more than 60 countries worldwide and is thus one of the largest family-owned companies in Europe. Being a technology leader, Voith sets standards in the markets of energy, oil & gas, paper, raw materials and transport & automotive.

The study of mica-epoxy-based composite has a great role in high voltage machines industry. Beside electric properties, this composite should present compatible mechanical and chemical, in this case thermal characteristics to insulate properly the conductor strand, avoiding short-circuits, and leading electrical current with minimal losses. Improvement of the quality is possible through the knowledge of raw materials and system. This study aims to list a complete thermal characterization of mica composite, its components, epoxy resin, anhydride methylhexahydrophtalic, mica tape and zinc naphthenate, and thermoanalytical interactions between them. These data shows intrinsic properties of the system, which is so relevant to its great electrical and thermal performance. Thermal analysis allows the detailed study of curing process and thermal decomposition, predicting and suggesting mechanisms, beside future and possible optimization to the system. Composite system glass transition (T g) was obtained through an important and very respected methodology, presenting the value of T g = 138 ± 2 °C, finally characterizing the material. © 2011 Akadémiai Kiadó, Budapest, Hungary.

Cure kinetics study of epoxy resin composite, employed as stator bars insulation system, was evaluated through differential scanning calorimetry using the dynamic methodology, different heating rates. These experiments provided some important information about the system as activation energy (E a = 65.4 kJ mol-1), glass transition (T g) values on different curing stages including the final cured material information and, besides that, it enables the comparison of these data with new materials under development. The activation energy value allows the determination of different energy needs of the system under evaluation, specially temperature for the material cure, improving the possibility of comparison between different insulation systems in use in the high voltage insulation business. The composite conversion degree based on the cure enthalpy (ΔH cure) at different time of cure was also subject of analysis and from that it was possible to comprehend the cure pattern which allows the cure state prediction of further samples of this type of material and the more accurate evaluation of similar samples acquired directly from stator bars. © 2011 Akadémiai Kiadó, Budapest, Hungary.

In spite of the fact that no evidence exist that PD amplitudes can somehow be used to estimate the expected 'life' of generator components such as Roebel stator bars and multi-turn coils, certain portions of industry have assumed that pass-fail criteria based upon absolute PD amplitudes are meaningful enough to be used as pass-fail tests for Roebel bars and Multi-turn coils. In this context the present work evaluated the ability of expert independent laboratories to generate reproducible PD readings when performing PD tests on the very same set of bars. © 2016 IEEE.

It is well known that part-load operation of Francis turbines is dominated by time-dependent phenomena. A high swirl level at the turbine runner outlet constitutes a complex inlet boundary condition for the draft tube flow at this condition. The draft tube flow simulation using a quasi-steady approach of typical two-equation turbulence modelling (k-ω SST) can provide good agreement between measurements and computational calculation for the optimum point. Global main structures of the flow as well as secondary flows can be well predicted. For part load condition this hypothesis is quite questionable due to different time scales which are associated to the different effects that can be observed at this condition. Steady state simulations do not predict the physics of the flow accurately. This work presents an evaluation of the part-load simulation results when applying a hybrid RANS-LES turbulence modelling approach using the finite volume method. Firstly, steady state results employing the k-ω SST turbulence model are presented. Then transient calculations employing both k-ω SST and SAS SST, a 2nd generation hybrid turbulence model, are also presented. In this model, a spatial filtering based on the grid size is not the main criteria applied to determinate the smallest calculated scales of the flow, but the instabilities of the flow field itself are the trigger for the reduction of eddy viscosity production. The effects of the mesh resolution on the solved turbulent structures are also evaluated. The numerical results are compared to time-averaged velocity profile data obtained by LDA (Laser-Doppler-Anemometry) measurements at the inlet of the draft tube diffuser of an nq=55 1/min Francis turbine. Velocity components in flow direction and transversal to it are evaluated. The investigation shows that the steady state results present considerable deviations when compared to those measurements. The transient calculations using the unsteady k-ω SST approach shows some improvement, but the tendencies are similar to steady state calculations. Calculations employing the SAS SST model shows overall better concordance between simulations and measurements. The results calculated with a finer grid model do not present significant improvement on the velocity profiles prediction when compared with the coarser grid one, although allowing the calculation of smaller eddies. © Published under licence by IOP Publishing Ltd.

33rd Electrical Insulation Conference, EIC 2015 | Year: 2015
The evaluation of high-voltage groundwall insulation aged under long-Term operating conditions is addressed using three sets of Roebel bars removed from large hydrogenerators after several decades of service. To cover an important cross-section of the possible operating regimes for typical hydros, the units involved in the study were selected to represent (i) the air-cooled Pumped-storage, (ii) the air-cooled base-load and (iii) the water-cooled base-load service regimes. Experimental techniques were used to permit assessment of the insulation condition under visual, electrical and morphological aspects. Contrary to what is usually assumed, the results suggest that the pumped-storage operating regime, with its repeated thermal-mechanical cycles of start-stops may create only minimum aging to the groundwall insulation while, in some particular cases, units operating at relatively low temperatures and under mild base-load conditions, may be found to exhibit a more severe insulation degradation in the long run. © 2015 IEEE.
