  • Brazil transmission: what impact on O&M?

    Brazilian wind developers may increasingly have to factor transmission links into their operations and maintenance (O&M) plans if grid connection delays persist in the market. Bloomberg earlier this year reported that firms such as CPFL Energia, Brazil’s largest private sector utility, with more than 1.3GW of wind farms in operation or under construction, were stepping forward to bid ...

  • Hansen transmissions - wind turbine gearbox testing with PULSE

    The Wind Energy Market Wind energy is one of the fastest growing power generation technologies. The level of annual installed capacity has grown at an average rate of 27.6% p.a. for the past five years. High fuel prices and increased focus on global warming and renewable energy resources have contrib- uted to an increased investment in the development of wind technology over the last three ...

  • Regional electricity price differences due to intermittent wind power in Germany: impact of extended transmission and storage capacities

    A fast growth of installed wind power capacity has been experienced in several European countries. In Germany, notably high wind power capacities are planned in the North. If the existing transmission capacities between individual regions become insufficient, the electricity prices will differ considerably and the system operation can become unstable. It is supposed that the extension of ...

  • Discussing the Impact of the Various Catastrophic Tornadoes on the Transmission & Distribution Systems

    Utility preparations for outage response and restoration are an ongoing, consistent problem. Through the year, storms cause disruption to the delivery of power and ultimately cost the utility industry money through lost revenue and system repair. Much of this preparation is focused on weather damage that may occur from hurricanes, thunderstorms, ice storms and various other natural events. Pam ...

  • A new fault detection, classification and location scheme for transmission line

    Using the powerful analysing and decomposing features of wavelet transform, a new fault detection scheme is presented. Further, the same technique has been extended for fault classification and accurate fault location from the relaying point to the fault using a radial basis function neural network (RBFNN) which provides a more efficient approach for training and computation. The relaying scheme ...

  • Software reliability estimation of computer relaying for transmission line protection using user-oriented software reliability model

    Advancement in signal processing techniques and VLSI technology has rapidly substituted conventional electromechanical relays with novel alternatives like digital relays, also termed as computer relays in power system parlance. A computer relay is considered as a digital signal processor which continuously processes the values of line currents and voltages. Hence, the heart of the computer relay ...

  • On limits for wind power generation

    The amount of wind power in the world increases fast. The background for this development is improved technology, decreased costs for the units and an increased concern of the environmental problems of competing technologies such as fossil fuels. For the future, it is now interesting to evaluate where the limits are for wind power generation, and which points are crucial. Since there is no power ...

  • The flawed economics of nuclear power

    Over the last few years the nuclear industry has used concerns about climate change to argue for a nuclear revival. Although industry representatives may have convinced some political leaders that this is a good idea, there is little evidence of private capital investing in nuclear plants in competitive electricity markets. The reason is simple: nuclear power is uneconomical. In an excellent ...

  • The Emerging Power of Microgrids

    Over many decades, the centralized power grid — a one-way flow of electricity, generated by large, remote power plants and distributed over miles of transmission lines to homes and businesses — succeeded in delivering electricity across continents to billions. But in recent years the system’s shortcomings have become increasingly ...

  • Harmonic assessment of electrical power systems

    Advances in semiconductor technology have resulted in an escalation in the numbers and power ratings of non-linear loads connected to the power system. At all voltage levels, equipment is being installed which generates harmonics. At transmission levels, FACTS devices are being installed for controlling power flow, HVDC links are used to transfer real power between AC systems and large industries ...

  • Brazil Power Report Q1 2013

    While hydroelectric sources of power account for, and will continue to account for, the majority of Brazil’s electricity consumption requirements, over the course of our forecast period gas-fired power stations will gain importance, as will renewables and nuclear sources of power, once Angra 3 begins operations in 2016. Brazil’s ambitious Belo Monte hydroelectric dam project ...


  • Solar power plants mw or kw?

    Solar power has come as a blessing to the humanity, not only to provide energy to all but to save humanity from the evils of industrial revolution. The biggest evil of industrial revolution in last two centuries is the concentration and centralization of wealth and resources and also huge political powers in the handful of people. So huge factories, mass production, big industrial and financial ...

  • Optimizing Wind and Solar Power in Africa

    Editor's Note: The following is a news release authored by Julie Chao and issued by Lawrence Berkeley National Laboratory on April 5, 2017 To meet skyrocketing demand for electricity, African countries may have to triple their energy output by 2030. While hydropower and fossil fuel power plants are favored approaches in some quarters, a new assessment by the Department of Energy’s Lawrence ...

  • Community Wind Power for Renewable Income

    CONSIDERING its incredible history and environmental benefits, wind power is one of the most underutilized sources of renewable energy. Stretching back as early as 200 BC, communities have been harvesting the wind for power. However, the scale and popularity of wind power is only now starting to reach critical mass as concerns of climate change rise and energy usage continues to soar. While ...

  • Solar thermal power coming to a boil

    After emerging in 2006 from 15 years of hibernation, the solar thermal power industry experienced a surge in 2007, with 100 megawatts of new capacity coming online worldwide. During the 1990s, cheap fossil fuels, combined with a loss of state and federal incentives, put a damper on solar thermal power development. However, recent increases in energy prices, escalating concerns about global ...

  • Ontario`s Wind Power Sector at a Crossroads

    Despite having Canada's largest population and being home to an energy-intensive manufacturing sector, Ontario was slow to adopt wind power. As recently as 2006, only 10 turbines were spinning in the province. However, the province is currently home to more than 1,750 MW of wind power and plans are in place for this figure to increase to 7,500 MW by 2018. The Policy Environment ...
