Wind Updates: Innovations and Improvements

Pitch control systems are housed within the spinner of the turbine and rotate at around 30 RPM, so using lead acid batteries can risk acid spillage and poor reliability, says PULS UK, the company responsible for the new power supply. PULS says its PAS395 delivers a high-charging current – a two-Farad capacitor will be fully charged in five minutes. Once charging is complete the charger has been designed to automatically switch to energy saving mode. The company says the unit can operate in temperatures between -40°C and +65°C and at up to 6000 metres, and comes with remote monitoring and control as standard features. Safety guidance issued The Energy Institute (EI), in collaboration with DNV (Det Norske Veritas), has published new guidance to help non-specialists manage human factors analysis of safety-critical tasks. This analysis can help reduce the chance of human failu...
