Lightning and surge protection for wind turbines

  Due to their vast exposed surface and height, wind turbines are frequently hit by direct lightning strikes. Comprehensive lightning and surge protection measures are essential to maximise the return on investment and prevent downtime. Download the PDF

Solar farm harvests energy in desert wasteland

  The UAE has embarked on an ambitious programme to introduce renewable energy into its generation mix. Homes, offices and other buildings in Dubai are now partially powered by the desert sun. Phase 1, which produces 13 MW, has been completed and is in operation. This article results from a visit to the site in […]

Success of biogas in Africa

  Biogas has huge potential in Africa. It can be deployed in remote areas in order to provide stable supplies of power. Due to the high cost of diesel and the unreliability of many African electricity distribution networks it is becoming a viable alternative for stable clean power. Biogas can be generated from a variety […]

Solar-aided power generation compared to stand-alone CSP

  A recent academic study compared solar aided power generation (SAPG) solutions with that of a similar-sized stand-alone concentrating solar power (CSP) plant in the South African context. The objective was to determine the real advantages of these technologies. Download the PDF document

Biomass fired power plants for distributed power generation

Rural areas of developing economies which are not served by the grid require alternate means of electric power generation. A system based on a Stirling engine could be an attractive option for distributed power generation in such conditions. Download the PDF

Ride-through testing of wind turbine converters

  The testing of low-voltage, ride-through capability of wind turbine converters has recently been standardised in the 2nd edition of IEC 61400-21. Thus, testing the converters in the factory is important to shorten the on-site testing time required to meet  IEC 61400-21 requirements. Download the PDF document
