The Prospect of Wind Power Generation As the traditional energy, such as fossil energy, getting less and less, Current Energy Issues get increasingly attention now. In consequence, the development of new energy becomes more and more urgent. We know, because of the difficulties of technology and the potential danger of the nuclear power, nuclear power is not adapted to most places, what’s more, it requires a lot on resource, which can hardly be massively collected on the earth. Therefore, it cannot be well developed currently. And as for hydrogen power, its preparation is not easy as well. Now human being has not found a proper way to create hydrogen depends on low energy and of easy raw materials. So to conclude, there massive new energy resources, but most of them are too regional that cannot be widely applied; or too assuming on cost, which are the barriers of its application. So now we turn to a kind of clean energy which has a positive prospect—Wind Power Generation, which is to change the easy-got and clean primary energy to a secondary energy resources—electricity, which is very convenient to transportation and application. It had been used to draw water for irrigation or mill flour. But now, it will be used for the public. The advantages of wind power generation are listed as following: 1. Its containing quantity is marvelous. The global wind power is approximately 2.74×109MW, of which 2×107MW is available. Which is more than ten times larger the total usable hydropower. 2. The resource spreads very widely so that it will not rely on some particular region like hydropower which must be built by a 3. As a clean renewable energy resource, when it is used, there will be no any pollution to our environment and it won’t die away before the sun. It is easy to understand, because what it use to create electricity is wind: after the fans driven by wind are speed up by the booster engine, the mechanic energy will be translated to electricity by electric generators. Therefore, no pollution has been produced. 4. The devices needed are very flexible, so that they can be assembled more easily, timesaving, and cost-efficient as well. What is used to develop wind power is called wind generating set, which consists of wind turbines(including tail rudder), electric generator and pylon, all of which are easy to produce and assemble. 5. In recent time, either in the world or our territory, the development of wind energy is very fast, which means the basement of the technology is generally built, the massive application is on ahead. As a matter of fact, there actually are some disadvantages about the new energy. Such as much occupation on the room, a little noise, and instability as well. But when taking the large territory and plentiful wind power into account, despite of these negative dimensions, it’s still very feasible to development this kind of new power. As the worldwide environment getting worse and worse as a result of human being’s activities, now it’s our time to develop a more environmentally-friendly way to get our necessary everyday energy. To solve the energy problem and keep a clean world as well, wind power resource is a proper solution we could adopt.
一个风力发电机一天能发多少度电
风力发电机的并网控制直接影响到风力发电机能否向输电网输送电能以及机组是否受到并网时冲击电流的影响。
并网控制装置有软并网，降压运行和整流逆变三种方式。
软并网装置： 非同步发电机直接并网时，其冲击电流达到额定电流的6~8倍时，为了减少直接并网时产生的冲击电流及接触器的投切频率，在风速持续低于启动风速一段时间后，风力发电才与电网解列，在此期间风力发电机处于电动机运行状态，从电网吸收有功功率、降压运行装置： 软并网装置只在风力发电机启动时运行，而降压运行装置始终运行，控制方法也比较复杂。
该装置在风速低于风力发电机的启动风速时将风力发电机与电网切断，避免了风力发电机的电动机运行状态。
整流逆变装置： 整流逆便是一种较好的并网方式，它可以对无功功率进行控制，有利于电力系统的安全稳定运行，缺点是造价高。
随着风电场规模的不断扩大和大功率电力电子设备价格的降低，将来这种并网装置可能会得到广泛的应用，风电场接入电力系统的方案主要由风电场的最终装机容量和风电场在电网所处的位置来确定

风力发电机输出电压依靠什么来稳定
风力发电最大的问题是风能的随机性，没法和负荷及时匹配独立发电的风力发电系统需要蓄电池等蓄能设备辅助调节，典型的方式为，风力发电机发出的电能经过整流后，给蓄电池充电，电池能量通过逆变器变为市电供用户使用。
但这样的系统只适合小功率的用户大型风力发电都是并入电力网运行，这样供电的连续性由其他发电系统保证，风电作用是节省整个系统的发电能耗。
由于风电本身供电是随机和不连续的此风电在系统中装机容量不得大于10%，而且必须有部分抽水蓄能电站和电网自动发电控制（AGC）相配合。
风力发电厂工资一般多少
风力发电厂是属于一个技术方面的工作,如果你从事到技术工作上,当然工资是很高的了.不管学历多高,刚出来主要是学习积累工作经验,所以主要是看你自己的兴趣了,到发电厂的工作是不错的.从事到一点技术上的工作,一般在2000元以上的.但如果你刚毕业,到里面慢慢学习,积累工作经验后自然工资会提高的.
风力发电厂待遇怎么样
还好吧，撑不着饿不着。
也要看你在什么地方的哪个公司的风力发电厂，还有岗位的不同，这些是有区别的。
基本上是从一般点的公司底层到好点的公司中层，年收入可能是3万到十几万
