April 11, 2022, 1:47 a.m. Updated 35 {"title": ["", "The development of a smart, rugged, ultraefficient grid tied interface for small wind turbines"], "description": ["", "\nThe UK\u2019s climate change target is to reduce greenhouse gas emissions by 34% in 2020 and\n80% in 2050 [DTI white paper]. Small wind turbines (SWTs) \u2013 rated up to 100kW \u2013 could be\npotentially make a significant contribution towards reducing GHG emissions. The\nGovernment has introduced a range of incentives to encourage the uptake of SWT\ntechnologies, incl. Feed-in-Tariffs (FiT), the Green Deal and removal of the need for planning\npermissions in some cases. Despite the recent increases in market uptake of SWTs, there\nremains a number of challenges that restrict both the maximisation of their power output and\nwider adoption of this promising renewable energy solution.\nSWTs typically employ fixed-pitch blades, which facilitate simple structure, low cost, and\nhigh reliability. However, due to the fixed nature of the blades, SWTs have a tendency to overspeed,\ncausing over-loading problems at excessive wind velocities. Overloading of expensive\nelectrical components is undesirable and often causes irreparable costly damage. An auto-stop\nfeature to prevent such incidences has not become commonplace due to cost and powering\nsupply limitations.\nThe nature of wind and its inherent fluctuations, mean grid connection inverters - which\nconvert DC current to grid compliant AC - must be oversized to deal with any excessive wind.\nOversizing is a crude way to deal with the issue, but this approach has become commonplace\nsince incumbent wind inverters are based on technology originally developed for generation\nof stable solar energy. The result of over specified inverters is highly inefficient (30-40%)\npower transfer at average site wind speed.\nFuturEnergy has developed an innovative system concept to overcome these problems. If\nsuccessful, we will capture roughly 10% of our markets and generate a cumulative revenue\ntotal of £13.7million. This revenue will result in a cumulative profit of £5.14million. With an\ninitial investment of £800,000, we estimate an attractive RoI of >600%.\n\n"], "extra_text": ["", "\n\n\n\n"], "status": ["", "Closed"]}
