  • 1 Decentralised Rural Electrification
    DECENTRALISED RURAL ELECTRIFICATION: THE CRITICAL SUCCESS FACTORS [EXPERIENCE OF ITDG1] By Ray Holland, Lahiru Perera, Teodoro Sanchez, Dr Rona Wilkinson Summary Rural areas of poorer countries are often at a disadvantage in terms of access to all types of services – roads, health facilities, markets, information, clean water. The high cost of providing these services in remote areas has led to new approaches being tried, based on self-help and the private sector rather than traditional government-led solutions. Energy services for household, agriculture and production are no exception. In the case of electricity, which has the potential to improve productivity and provide considerable welfare benefits (lighting, entertainment, etc.) traditional grid extension is no longer seen as the only solution. Decentralised supplies, whether at an individual household level or at community level, are now an established, cost-effective alternative for the two billion rural people who are currently without access to mains electricity. In many cases renewables provide the most financially attractive means of providing that energy. Supplies may be of a similar standard to grid supplies (mini-grids supplied by diesel or micro hydro) or they may be low voltage household supplies (PV, battery charging). This review of recent practice draws on ITDG’s twenty years experience of supporting off-grid solutions in Sri Lanka, Nepal, Zimbabwe and Peru in particular, and on work by other organisations in other countries, such as Indonesia, Kenya, Vietnam, South

  • Science Form 3 Chapter 8 Generation of Electricity
    SCIENCE FORM 3 CHAPTER 8 GENERATION OF ELECTRICITY • Electrical energy for home and commercial use is produced by machines called generators. • Generators convert mechanical energy to electrical energy. • A generator consists of copper coils surrounded by magnet • Turbines are usually connected to the copper coil of the generator by a shaft. • When the turbines are turned, the spinning shaft will cause the copper coil to spin and electrical energy is produced. Types of generators [ depends on sources of energy available on Earth] I. Thermal a. Sources: Fossil Fuel II. Hydroelectric a. Sources: Water III. Gas turbine a. Sources : Petroleum and natural gas IV. Diesel a. Sources : oil V. Nuclear a. Sources: Uranium Types of power station Thermal power station • coal, oil or gas is burnt in the furnace. Heat energy released is used to heat water in the boiler. • The water changes to high-pressure steam • The high pressure steam is used to turn the turbines which are attached to the generator • Electricity is produced in a generator by spinning an electromagnet inside fixed coils of wire • The condenser changes the steam back to water. Water is pumped back to the boiler • Vast amount of water are needed for the condenser and this can be obtained from a nearby river or lake 1 The Classroom Learning Academy Hydroelectric power • Water is held in a large reservoir station • Running water falls from the dam through a tunnel to spin the turbine • the turbine is attached to generators to produce electricity • no fuel is needed to supply energy to

  • Residential Power Never Lack Power !
    Residential Power Never lack power ! The generating sets in the new Residential Power range are of professional quality but are compact and sound insulated for home use. SDMO® generating sets are simple and practical and can be installed permanently outdoors. They start up automatically if there is a power cut, ensuring that life in the home can continue as normal – refrigerators and freezers will keep running, that heating and alarms systems will continue to operate and those working from home will not be disturbed. Residential Power run off LPG or natural gas. They are quiet and environmentally friendly with low emissions. Practical, automatic, simple: an alternative source of electricity that is always available ! Operating principle: Mains supply OK While the mains power supply is OK, The automatic transfer switch detects the the ATS* connects the mains to the distribution board. presence of the mains and selects the power source. If there is a power cut, the automatic transfer switch starts the generating set and switches the power source to restore the electrical supply within a few seconds. When the mains electricity supply returns to normal, the automatic transfer switch switches back to the mains, turns off the genset and continues to monitor the mains supply. * ATS : Automatic Transfer Switch Power cut When there is a power cut, the automatic transfer switch detects that there is no mains electricity and starts the generating set. The distribution board is then supplied from the genset which provides electricity to the home. SDMO Industries - 12 bis, rue de la Villeneuve - CS 92848 - 29228 BREST Cedex 2 - France Tél.

  • Pioneering Energy Storage System Successfully Supports District Isolated from Mains Electricity for a Record 5 Hours
    Press release Pioneering energy storage system successfully supports district isolated from mains electricity for a record 5 hours Benfeld, 16 December 2015 Following a test period over several months on “Concept Grid” - EDF R&D’s1 experimental platform in Seine-et-Marne - teams from French distribution system operator ERDF2 and power conversion specialists, SOCOMEC, have successfully validated the islanding of an entire district for periods up to a record 5 hours. This operation is part of the smart solar district pilot site -Nice Grid in the south of France - an ambitious smart electricity network project that generates and stores large amounts of solar energy. The global targets to reduce harmful emissions associated with the production of electrical power require a massive integration of renewable energy into our electricity networks. In order to support this significant integration – whilst also maintaining the quality of the networks – intelligent, decentralised systems are required to intermittently store the energy produced and to regulate distribution according to demand. ERDF, which is spearheading the project, targeted a district comprising 8 industrial clients and 3 large photovoltaic installations, generating a total of 430 kWp. An energy storage solution has been installed with a control system specifically designed to manage the disconnection and reconnection of the district to the mains supply. In disconnected or “islanded” mode, industrial clients continue to be supplied via Socomec’s PCS²’s energy storage system and photovoltaic production. Giovanny Diquerreau, Energy Storage Projects Director at Socomec, explains; “The Nice Grid project demonstrates that the local management of variable energy flow is achievable via efficient energy storage solutions.

Pricing Electric Power in the Czech Republic and in Selected Countries. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 64(3): 1001–1011. This paper focuses on state intervention in the pricing of electricity from renewable power sources in the Czech Republic when compared with the pricing in the Slovak Republic, Germany, France and Italy. In these countries the state intervention is implemented in diff erent forms, but the critical part of the price is regulated everywhere by the state. The price of electricity is determined by its production costs, which depend on the source from which electricity is produced. The highest cost of electricity is required to generate renewable energy, particularly solar power, while the lowest costs of power are associated with its production by coal-fi red and natural gas-fi red thermal power plants. However, hydroelectric power plants attain clearly the lowest cost for generating electricity. State intervention includes

  • AC, DC and Electrical Signals
    From http://www.kpsec.freeuk.com/acdc.htm © John Hewes 2006, The Electronics Club, www.kpsec.freeuk.com AC, DC and Electrical Signals AC means Alternating Current and DC means Direct Current. AC and DC are also used when referring to voltages and electrical signals which are not currents! For example: a 12V AC power supply has an alternating voltage (which will make an alternating current flow). An electrical signal is a voltage or current which conveys information, usually it means a voltage. The term can be used for any voltage or current in a circuit. Alternating Current (AC) Alternating Current (AC) flows one way, then the other way, continually reversing direction. An AC voltage is continually changing between positive (+) and negative (-). AC from a power supply The rate of changing direction is called the frequency This shape is called a sine wave. of the AC and it is measured in hertz (Hz) which is the number of forwards-backwards cycles per second. Mains electricity in the UK has a frequency of 50Hz. See below for more details of signal properties. An AC supply is suitable for powering some devices such as lamps and heaters but almost all electronic This triangular signal is AC because it changes circuits require a steady DC supply (see below). between positive (+) and negative (-). Direct Current (DC) 1 Direct Current (DC) always flows in the same direction, but it may increase and decrease. A DC voltage is always positive (or always negative), but it may increase and decrease. Electronic circuits normally require a steady DC supply which is constant at one value or a smooth DC supply Steady DC which has a small variation called ripple.
