GE再发生一起机组倒塔事故
中国风电新闻网讯：9月3日，位于巴西东北部Omega Energia公司的 Delta 6 风电场发生一起风电机组倒塔事故，事故机型为GE 2.72-116，目前GE已经对事故发生的原因展开调查。
据悉，事故发生时，现场共有3名GE员工，1名工人在事故中受伤，目前在医院接受治疗。
据了解，Delta 6 风电场项目于2018年投入运行，本次事故机型为GE 2.72-116，这也是GE今年发生的第五起类似事故。
上一次（第四次）
据外媒（Rechargenews）报道，近日位于巴西伯南布哥州东北部某风电场发生一起风电机组倒塔事故，该风场总装机216MW，事故机型为GE 1.7MW-103机组，这是GE过去5个月在美洲发生的第四起此类事故。
GE表示，已派出一个专家小组与项目开发商Echoenergia展开联合调查，以确定事故发生的“根本原因”。
据当地媒体报道，事故发生当天，该地区最大风速达到27m/s，远高于该地区通常8-12m/s的风速。
倒塔事故归咎于风机在大风期间以超速模式运行，而叶片相关的熔断器出现问题，导致叶轮不平衡，最终倒塌？

GE turbine collapses in Brazil, the fourth in the Americas this year
A 1.7MW GE turbine has collapsed at a wind farm in Brazil, the fourth such incident for the US manufacturer in the Americas in the past five months.
The collapse at the 216MW Ventos de São Clemente wind complex in the northeastern state of Pernambuco, which has been confirmed by GE, comes as the OEM probes three recent turbine collapses in the US — in February, May and July — and after a leading renewables insurer has raised concerns about the possibility of a pattern emerging.
Those three incidents were said to be unrelated, according to the manufacturer.
GE said it has already sent a team of experts to work with the project developer, Echoenergia — which is owned by British venture capital fund Actis — to determine the "root cause" of the accident. The destroyed turbine, a 1.7-103 model, was almost certainly built at the company's factory in Sâo Paulo state.
Although accidents have been seen in Brazil in turbines manufactured by other OEMs, this is the first GE machine reported to have collapsed since the start of Brazil's wind power industry about a decade ago.
A journalist at Caetés News, a local online news service, told Recharge that a blade fell off the turbine during strong winds at around 10.30am on Sunday, which caused the machine to lose stability and then crash to the ground. Wind speeds reportedly topped 100km/h (27m/s) on Sunday — far higher than the usual 8-12m/s winds in the region.
Brazil's 15GW-plus wind industry has seen very few accidents, partly because the majority of the country’s 7,000 turbines are less than ten years old.
Recent accidents have included fires in old Suzlon machines, due to bad maintenance, and the collapse of eight Impsa turbines in southern Brazil.
GE has the biggest wind turbine fleet in Brazil, with more than 3,000 machines, after acquiring French turbine maker Alstom in 2015.
