摘要：
风机是一种将原动机的机械能转换为输送气体、给予气体能量的机械，它是火电厂中不可少的机械设备，主要有送风机、引风机、一次风机、密封风机和排粉机等，消耗电能约占发电厂发电量的1．5％～3．0％。在火电厂的实际运行中，风机，特别是引风机由于运行条件较恶劣，故障率较高，据有关统计资料，引风机平均每年发生故障为2次，送风机平均每年发生故障为0．4次，从而导致机组非计划停运或减负荷运行。因此，迅速判断风机运行中故障产生的原因，采取得力措施解决是发电厂连续安全运行的保障。虽然风机的故障类型繁多，原因也很复杂，但根据调查电厂实际运行中风机故障较多的是：轴承振动、轴承温度高、动叶卡涩、保护装置误动。
多年以来，风力发电机同水力机械一样，作为动力源替代人力、畜力，对生产力的发展发挥过重要作用。近代机电动力的广泛应用以及二十世纪50年代中东油田的发现，使风力机的发展缓慢下来。七0年代初期，由于“石油危机”，出现了能源紧张的问题，人们认识到常规矿物能源供应的不稳定性和有限性，于是寻求清洁的可再生能源遂成为现代世界的一个重要课题。风能作为可再生的、无污染的自然能源又重新引起了人们重视。近两年，特别是《可再生能源法》的正式实施，为我国风力发电创造了良好的发展环境，根据《中国风电发展报告2007》预测，国内风电机组将以每年37.4%的速度递增，依据现有政策，中国风电装机容量到2020年底可达到5000万千瓦。目前风力发电机组趋向大型化,目前全国安装风力发电机组平均功率达到1.5MW以上。大型机组的吊装给风机安装带来新的课题。本文就工程实例描述了风力发电机组安装过程。并对风力发电机组做了简述。

Abstract：
Is a fan of the original motive of the mechanical energy is converted into gas, gas energy to the machinery, it is theindispensable equipment in thermal power plant, main blower, induced draft fan, a fan, sealing blower and exhauster,electric energy consumption accounts for about 1.5% of to power generation power plant 3%. In the actual operationof thermal power plant, wind machine, especially the fan because the operating condition is bad, high failure rate,according to the relevant statistics, the average annual incidence of induced draft fan fault for the 2 time, the bloweris average and annual failure for the 0.4 time, causing unplanned outage or reduce the load operation. Therefore, to quickly determine the fault reasons of fan operation, take effective measures to solve the power plant for the protection of the safe operation of. Although the fault type fan is various, the reason is very complex, but according to the actual plant operating stroke engine fault is more: bearing vibration, high bearing temperature, dynamic leaf cards astringent, protection misoperation.
Over the years, wind power generator with hydraulic machinery, as the power source to replace human, animal,played an important role in the development of the productive forces. Modern electrical power and the wide application of the twentieth Century 50's Middle East oil discoveries, the development of wind turbines to slow down.0 in the early seven, due to the "oil crisis", appeared the problem of energy shortage, people realize that theconventional fossil energy supply instability and limited, so look for clean renewable energy has become an important topic in modern world. Wind as a renewable, non polluting natural energy again attracted attention. In recent years, especially in the formal implementation of "renewable energy law", to create a favorable environment for the development of China's wind power generation, according to "Chinese wind power development report 2007"prediction, the domestic wind turbines will be increased by 37.4% every year, according to the existing policy,Chinese wind power installed capacity by the end of 2020 can be achieved 50000000 kw. Wind power generation unit is tending to increase, the average power of the wind turbine installed above 1.5MW. The hoisting of largegenerator for wind turbine installation bring new task. This paper describes the installation process engineering example of wind turbine. And the wind turbine is briefly introduced.
