  • What 2017 holds for Energy from Waste in the UK

    The UK’s EfW industry has enjoyed two decades of stable investment under the public private partnership (PPP)/public finance initiative (PFI) regime. This has led to a reduction in the amount of biodegradable household waste sent to landfill via the construction of local authority-backed EfW plants and contributed to an increase in recycling rates by incorporating facilities that remove ...

  • A breath of nothing is decisive: AERZEN Turbo blowers with air bearings provide clear advantages compared to blowers with magnetic bearings

    Aeration tanks for wastewater treatment must be continuously provided with large air volumes. Turbo blowers offer here energy-efficient solutions. AERZEN has developed an amazingly simple method for the fast-rotating Turbo blowers - air bearings. The construction of AERZEN Turbo blowers is quite simple: A blade wheel, aerodynamically optimised and located directly on the motor shaft, rotates in ...

  • Corporate sustainability: A guide to measuring and improving energy efficiencies

    As environmental scrutiny of global industries continues to grow, governments are seeking to impose energy efficiency targets on companies in order to comply with new directives. One solution is to encourage energy suppliers to become energy service companies, who work with customers to identify potential savings and share the benefits this delivers. For the global food processing industry, this ...

  • Energy management for smart community

    Under the project title “Smartes Yspertal” an energy management concept for municipal administration buildings was created in the 1,900 inhabitant community in Lower Austria. Savings potential and inefficiencies in public buildings are thus to be shown. Microtronics has equipped the buildings with data loggers of the type ...

  • Hidden failures in electric power systems

    Hidden failures in equipment are those failures which occur at random and that do not lead to any discernible change in the state of the network and, therefore, remain undetected. Although hidden failures can occur in any equipment, the hidden failures in protective equipment have attracted a good deal of attention in recent years. Admittedly these failures are rare but, when the power system is ...

  • 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 ...

  • Agents controlling the electric power infrastructure

    The electric power grid is evolving from a centrally controlled grid with only a handful of regulated monopolies to an open, liberalised electricity market. In addition, more and more small-scale dispersed generators are deployed in distribution nets. This puts extra stress on the power grid, in an era when electricity is one of the most important commodities for economic, industrial and everyday ...

  • Electricity trading in Indian restructured power market

    In the past few years, most of the electricity industries around the world have been undergoing a movement from monopoly utilities to restructured competitive electricity markets. At present time, the operation of electricity markets all over the world varies from one country to another. Indian electricity market is trading with power transactions through power exchanges. Practically, Indian ...

  • Power management policies and control of hybrid electric vehicle

    With increasing concern over the environment and ever-stringent emission regulations, the use of hybrid electric vehicle (HEV) is being investigated as an alternative form of transportation. A hybrid vehicle combines the advantages of an electric drive and an internal combustion engine. This paper proposes the necessary hardware and software needed for an effective control of the electrical part ...

  • Online condition monitoring of electrical power system imbalance

    Symmetrical components are of great importance in many applications in electrical power systems, such as power protection and condition monitoring. This paper presents a computer-based algorithm for online symmetrical components estimation. The proposed algorithm uses the samples of the phase variables (currents or voltages) to estimate the magnitude and phase angle of each phase phasor at each ...

  • Benefits of the Best Pressure Washers Powered By Electricity

    Ask any expert about the best pressure washers and they are likely to mention the electric powered versions. Since they run on electricity, the electric-powered ones are highly versatile and ideal for use in almost all settings with reliable electrical supply. The cleaning efficiency of the best pressure washers is measured in terms of their pressure in psi (pounds per square inch) and flow ...

  • Electric vehicles powering communities through natural disasters

    Mass power outages and blackouts have always been of great concern during and after natural disasters. In addition to the devastation that can occur from flooding, collapsed buildings, and disruptions to basic infrastructure, the absence of electricity can shut down basic communications systems, adding to the anxieties of those most critically affected. While much discussion revolves around what ...

  • Assessing the impact of interdependencies in electric power systems

    Electric power systems (EPS) greatly support our daily activities and are therefore among the most prominent critical infrastructures that need to be reliable and resilient in providing their services. They are rather complex and vulnerable systems, being composed by two interdependent infrastructures: the electric infrastructure (EI) and its information-technology-based control system (ITCS), ...

  • Is nuclear power more competitive producing electricity or hydrogen?

    Steam methane reforming is the world's dominant hydrogen production technology, using natural gas as both feedstock and fuel, but producing more than 9 kg of CO2 for each kilogram of H2. Natural gas prices between $6 and $8/GJ yield an average hydrogen production cost between $12 and $15/GJ, excluding the cost of CO2. High-temperature gas ...

  • Risk assessment of catastrophic failures in electric power systems

    The declining reliability of the US electric power system is raising major concerns among both politicians and power engineers in the USA. One of the reasons put forward by the North Electric Reliability Council (NERC) is the detrimental role played by the protection systems during large disturbances, which tend to help the perturbations to propagate through over-tripping of fault free system ...

  • Disposal of saline wastewater from electrical power plants

    Saline wastewater from a coal-fired Utah Power Plant has been applied in central Utah, USA, since 1987, to irrigate various agricultural crops. The primary goals of this research: to dispose of saline wastewater by maximising actual evapotranspiration (ETa) and to prevent contamination of surface and groundwater by eliminating runoff and throughout the years (1987-2005). Plots were established ...
