复杂环境条件下风力发电设备吊装技术研究

1、    复杂环境条件下风力发电设备吊装技术研究    石川【摘 要】华能布拖二期（补尔）风电场是凉山州规划建设千万装机风电基地的前期重要工程，本工程装机25台单机容量2.0mw的风力发电机组，年发电量在8000万kw.h左右，通过输电线路将清洁能源输送至千家万户。该工程所在地因为特殊地理条件造成大雾天数多、能见度低，且地形复杂，极不利于吊装，安装机型为fd108c型风力发电机组，叶轮旋转直径108m，安装难度极大。施工过程中，水电九局深入技术研究、加强管控、优化技术方案，解决了施工难题，确保项目进度、质量、安全可控，提高了公司声誉，取得了良好经

2、济效益。为解决具体的施工难题，以布拖风电吊装为背景，深入分析能见度低，安装困难条件下进度、安全、工效等方面的施工难点，总结了针对本工程施工难点采取的具体处理对策，以确保施工安全，提升施工进度，节省成本投入。【关键词】复杂地形;低能见度;吊装;技术research on hoisting technology of wind power equipment under complex environmental conditionsshi chuan（china water resources and hydropower ninth engineering bureau co.， ltd
