陕西省首个风电项目将在靖边建设

Dianci bileiqi, 2008
由山东鲁能发展集团有限公司投建的靖边县48 MW风电项目近日经陕西省发改委批复,成为全省核准建设的首个风力发电项目。靖边县计划于2008年4月在席麻湾乡牛圈梁附近的山脊开工建设。该项目总投资48 860.25万元,建设期为2 a,共需安装32台风力发电机,每台装机容量为1 500 kW,每台风机配一台容量为1 600 kV.A的箱式变压器。风力发电机组按6-9台一组分成4组,经4条35 kV电缆接入风电场110kV升压站,经110kV架空线接至靖边330kV变电站,并入国家电网。

百米级尺寸风机叶片雷电下行先导接闪特性的仿真研究

Dianci bileiqi
针对百米级长度风力发电机叶片雷击接闪特性不明晰、防护设计缺乏依据的问题，本研究建立了大容量风机叶片雷击接闪过程的三维仿真模型，模型计算结果与运行数据吻合。计算获得了6.7MW风机叶片沿长度方向不同位置的雷击暴露空间和年雷击次数的分布特征，结果表明随着雷电流幅值增加，叶尖的引雷能力增强并对叶片内侧存在屏蔽作用，自叶尖往叶根方向年雷击次数迅速衰减。当风机叶片与纵轴线夹角为90°时，叶片内侧遭受雷击的风险最高。与1.5MW机组相比，6.7MW风机叶片内侧年雷击次数增加1.71倍。分析表明，雷电流幅值为5.0 ...
