  • Drones for Wind Turbine Inspection

    Unmanned Aerial Vehicles and Inspection Services for Wind Turbines: Global Market Assessment and Forecasts By the beginning of 2015, there were nearly 270,000 individual wind turbines operating globally. The more than 800,000 blades spinning on these turbines are battered by the elements over time and gradually wear out. Deterioration can cause reduced energy ...

  • A combined electro-mechanical control technique for dynamic voltage regulation of a stand-alone wind turbine generator

    This paper introduces a computer-based model and dynamic simulation of a combined electro-mechanical control technique for a stand-alone wind turbine generator system. The presented combined control technique consists of three closed loops for speed regulation, nacelle alignment and dynamic load voltage regulation. Speed regulation is achieved by adjusting the pitch angle of the turbine blades. ...

  • Vector control of current regulated inverter connected to grid for wind energy applications

    Connecting variable speed wind turbine connected to the grid requires a proper control of the inverter to improve the power quality for the system. The vector control of an inverter connected to the grid is presented. The proposed control technique implies a hysteresis current controller in the inner loop. The complete control system has been developed, analysed, and validated by simulation ...

  • Sub and super-synchronous wind turbine-doubly fed induction generator system implemented as an active power filter

    This paper deals with a wind energy conversion system (WECS), based on a doubly fed induction generator (DFIG) and an electromechanical active power filter (APF). The objective is to respond simultaneously to electric energy requirement and power quality concerns. The proposed WECS is able not only to track the maximum power point of the wind energy but also to dampen harmonic currents from the ...

  • 2013 to be Record Year for Offshore Wind

    Offshore wind power installations are on track to hit a seventh consecutive annual record in 2013. Developers added 1,080 megawatts of generating capacity in the first half of the year, expanding the world total by 20 percent in just six months. Fifteen countries host some 6,500 megawatts of offshore wind capacity. Before the year is out, the world total should exceed 7,100 megawatts. Although ...

  • Wind & solar energy and nature conservation

    Climate change and the degradation of ecosystems and biodiversity cannot be solved in isolation. Land and marine ecosystems play a crucial role in the climate system, capturing roughly half of carbon dioxide emissions generated by human activities (UNEP, 2009). Protecting biodiversity preserves ecosystem services that are important for regulating the climate and helping us to adapt to the impacts ...

  • Prospect of offshore wind energy development in Japan

    In Japan, the cumulative capacity of wind turbine generation systems on land has increased steadily in recent years. To install a large number of wind turbines has inherent problems such as shortage of suitable land, and inadequate infrastructure such as power cables and roads. The necessity for development of offshore wind turbine generation systems has been recognised based on the above ...

  • Offshore wind installation vessel capacity to tighten after 2020

    The existing fleet of turbine and foundation installation vessels is well suited to serve the European offshore wind market in the short and mid-term but it will not be sufficient to support installation demand after 2020, Michael Guldbrandtsen, senior consultant at MAKE Consulting, told Wind Energy Update. The next 2-3 years will continue to be dominated by orders for jack-up ...

  • An integrated assessment for wind energy in Lake Michigan coastal counties

    The benefits and challenges of onshore and offshore wind energy development were assessed for a four‐county area of coastal Michigan. Economic, social, environmental, and spatial dimensions were considered. The coastal counties have suitable wind resources for energy development which could contribute toward Michigan's ten percent renewable energy standard. Wind energy is cost‐effective with ...

  • A summary of wind power impacts on electric power system operating costs

    Wind power plant output depends on wind speed. Such speeds cannot be accurately predicted over daily periods because the wind fluctuates from minute-to-minute and hour-to-hour. Consequently, electric utility system planners and operators are concerned that variations in wind plant output may increase the operating costs of the system. This concern arises because the system must maintain balance ...
