GE再發(fā)生一起機(jī)組倒塔事故
中國風(fēng)電新聞網(wǎng)訊：9月3日，位于巴西東北部Omega Energia公司的 Delta 6 風(fēng)電場發(fā)生一起風(fēng)電機(jī)組倒塔事故，事故機(jī)型為GE 2.72-116，目前GE已經(jīng)對事故發(fā)生的原因展開調(diào)查。
據(jù)悉，事故發(fā)生時，現(xiàn)場共有3名GE員工，1名工人在事故中受傷，目前在醫(yī)院接受治療。
據(jù)了解，Delta 6 風(fēng)電場項(xiàng)目于2018年投入運(yùn)行，本次事故機(jī)型為GE 2.72-116，這也是GE今年發(fā)生的第五起類似事故。
上一次（第四次）
據(jù)外媒（Rechargenews）報道，近日位于巴西伯南布哥州東北部某風(fēng)電場發(fā)生一起風(fēng)電機(jī)組倒塔事故，該風(fēng)場總裝機(jī)216MW，事故機(jī)型為GE 1.7MW-103機(jī)組，這是GE過去5個月在美洲發(fā)生的第四起此類事故。
GE表示，已派出一個專家小組與項(xiàng)目開發(fā)商Echoenergia展開聯(lián)合調(diào)查，以確定事故發(fā)生的“根本原因”。
據(jù)當(dāng)?shù)孛襟w報道，事故發(fā)生當(dāng)天，該地區(qū)最大風(fēng)速達(dá)到27m/s，遠(yuǎn)高于該地區(qū)通常8-12m/s的風(fēng)速。
倒塔事故歸咎于風(fēng)機(jī)在大風(fēng)期間以超速模式運(yùn)行，而葉片相關(guān)的熔斷器出現(xiàn)問題，導(dǎo)致葉輪不平衡，最終倒塌？

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.
