 今天Erik 老师Lecture的主题是Environmental impact of wind turbines”,ta他阐述了环境因素对风机选址的一些影响,如:风机运行过程中产生的噪声、风机塔筒的阴影。通过一个视频展示了风机塔筒产生的阴影对附近居民客厅光线产生的不利影响,也使我们认识到了如果风机选址不当会带来的严重后果。最后介绍了瑞典对于环境对风机选址的一些严格要求,例如:居民区噪音不得高于40分贝,往往35分贝以下是可以被接受,才能取得政府的授权。瑞典工程师在考虑工程问题时特别注重对环境的影响,老师的一句All the engineering works are to provide a better service for people”引起了我们的思考,这种思想是值得我们借鉴的。

Today, the theme of Erik Lecture is "Environmental impact of wind turbines", which first describes some of the effects of environmental factors on the location of the fan, such as the noise generated during the operation of the fan, the shadow of the fan tower, the fan The adverse effects of the shadows produced by the tower on the proximity of the inhabitants of the living room also led us to the serious consequences of the improper location of the wind turbine. Finally, we introduced some of the stringent requirements for the location of the wind turbine in Sweden, The environment shall not be higher than 40 dB, often 35 dB below can be accepted in order to obtain government authorization. Swedish engineers are particularly interested in the environment when considering engineering issues. The teacher's "

众所周知,风能作为一种新能源得到快速的发展,装机容量也在逐年增加。随之而来的风机产生的噪音及阴影对周围居民的影响也越来越被科研者关注。今天老师教我们利用WindPRO 3.11软件对风电场的噪音及阴影实现仿真。

It is well known that wind power as a kind of new energy sources to get fast development. The installed capacity is increasing year by year. Followed by the turbines noise and the shadow influence on the surrounding residents is becoming more and more concerned by researchers. Today the teacher taught us using WindPRO 3.11 software noise and shadow to realize the simulation of wind farm.

WindPRO是丹麦EDM公司开发的风电场规划设计软件,经过20多年的发展,WindPRO已成为使用最广泛、用户界面最友好的风资源分析与风电场设计软件。本课堂任务是利用WindPRO 3.11软件对风电场的噪音及阴影实现仿真。首先通过谷歌地图选出在风电场周围有居民的场地,场地选出后安装风机,安装风机的时候要注意风机间距,而且一个风电场内风机的类型要一致;其次,画出噪声敏感区,设置噪声敏感最大值为40db,进行仿真。如果仿真结果显示噪声超过40db,则风机安装在此不合适,需要重新规划风机位置。接下来进行阴影仿真,在刚才选出来的风电场附近画出阴影区,设置参数及阴影值,进行仿真。如果超过阴影值,则需要重新规划风机的位置。

WindPRO EDM is Denmark wind farm planning and design of the software development company. After 20 years of development, WindPRO has become the most widely used, the user interface is the most friendly wind resource analysis and wind farm design software.This classroom task is to use WindPRO 3.11 software to simulate the noise and shadow of wind farm. Firstly, through the Google map, the site of the residents around the wind farm is selected. After the site is selected, the turbines should be installed and the turbines spacing should be paid attention to  and the type of the turbines in a wind electric field should be the same. Secondly, the noise sensitive area is drawn and the maximum noise sensitive maximum is 40db, and the simulation is carried out. If the simulation results show that the noise is more than 40db, then the turbines installation is not suitable, and the turbines location needs to be replanned. Next, the shadow simulation is carried out. The shadow area is drawn near the selected wind farm, and the parameters and shadow values are set up to simulate. If you exceed the shadow value, you need to reprogram the fan position.

在整个上午学习的过程中,老师鼓励自己学习软件,如果遇到什么问题,可以问老师,老师会很耐心的解答及讲解原因。这种教学方法能加深对这个课题的理解,以及提高自己动手能力和对新东西的学习能力,值得我们学习。

During the whole morning study, the teacher encouraged us to learn the software. If we encountered any problems, we could ask the teacher, and the teacher would be patient and explain the reason. This kind of teaching method can deepen the understanding of this subject, and improve the ability of diy and learning new things, which is worth learning.

 今天我们继续学习windpro里面的阴影和噪声的仿真功能,我们在昨天已经建立好风电场场上,进行仿真,但是仿真数据一直不符合要求,只能不断调整风机的位置,以达到任务要求,在调整了十几次以后,终于满足要求,今天虽然是自习但是大家的学习热情依然高涨,每一组的同学都在努力学习Windpro这个软件,相信等学习结束,大家一定收益良多。

Today we continue to learn windpro and its the shadow and noise simulation function. We have already established a good wind field yesterday and do a simulation in this wind field. However the simulation data is not in conformity with the requirements. We should adjust the position of the fan, in order to achieve the requirements. After adjusting for several times, we finally meet the requirements. Although today is selfstudy, everybody's enthusiasm remains high. Each group of students are working hard with windpro. Believing that after learning, we must benefit

今天课程表上没有我们组的课,但还是有一些任务,主要是对前几天课上的仿真结果进行整理汇总分析,并查阅资料完成课程报告。我们先是去学校的图书馆查询了一些关于不同发电形式对于环境的影响的资料,主要包含的是风能、水能、煤以及核电对该地、该区域以及全球的影响,然后分析了通过WindPRO软件仿真后的报告,最后按照课程任务的要求,完成了报告以及汇报PPT。

Our group have no class today, but there are still some tasks, the task is mainly carried out summary analysis of the simulation results on a few days ago, access to information and complete the report the course. We first go to the school library to check some information about the environmental effects of different forms of power generation, including the effects from wind, hydro, coal and nuclear on local, regional as well as a global basis. Then we analyzed the simulation report by WindPRO. Finally according to the requirements of the project task, we finished the PM and the PPT.

今天是Erik风电方面课程的最后一次课,感觉真是时光飞逝。回想起来,他的课程主要内容包括不同种类风机的讲解,风场选址涉及到的问题,模拟仿真软件WindPRO的使用,以及真实风机的参观和试爬等等。其中印象最深刻的还是爬风机的那次经历。虽然平时我很热爱冒险和挑战,但是即使有很多设施的保护,爬到风机顶端的时候也没那么容易。按照Erik的讲解,这台风机属于非常小型的风机,只有约三十米高,重要的部件如发电机、齿轮箱、刹车等都在顶端。当到达顶端的那一刻,还可以感受到整台风机在晃动,不过从上面俯瞰周围景象的时候,感觉这一切都是值得的。


Today is the last day of Erik’s wind power lecture. How time flies! From the beginning, his class included different types of wind turbines, essential problems of farm siting, simulation of WindPRO and visiting and climbing the real turbine. The most impressive one is the venture of climbing real turbine. Although I appreciate adventures and challenges usually, it is still not that easy for me to climb to the top of it even with full protection from lots of equipments. According to Erik’s explaining, this turbine is a very small one, about 30m tall. The important components, like generator, gearbox, brake are on the top. When I arrived at the top, I could feel that it was shaking, but it worth enjoying looking around the view from the top to the ground, absolutely.
