    The new type of Vertical Axis Wind-Power Turbine ( VAWT )

                                                   The new type of Vertical Axis Wind-Power Turbine ( VAWT )

     

       In the 90’ of the 20th, there was only one type of wind-power turbine, the Horizontal Axis Wind-Power turbine ( HAWT ). It has been used to supply the power for the telecommunication stations, the border posts, the inlands and for the countryside etc..

       Later on, many shortcomings were found from the HAWT, such as easily to be damaged, big noise and disturbance to the nearby electrical equipments etc.. In such case, we realized that we should find some new type of wind-power turbine in stead of the HAWT.

       In order to manufacture the better wind-power turbine, in 2001, co-operated with some famous experts for the first class universities, we, Shanghai MUCE Electric Equipment Co., Ltd. ( MUCE ) started the research work on the Vertical Axis Wind-Power Turbine ( VAWT ). In a period of shorter than one year, we completed the research work and made one sample equipment which passed all the technical tests and finally got the confirmation from our clients including the army. Till now we have supplied more than 60 sets of VAWT to our customers domestically and internationally.

    The design principle of the new VAWT

    Here we are going to make some detail introduction on the design principle of the new VAWT to meet the needs of our clients.

    At the very beginning, the VAWT was of the arc shape of two blades called ф type VAWT. Its area facing the wind is quite small, hence bigger wind power will be needed for starting the turbine. So finally no one was interested in such turbine. We once also tried to make this kind of turbine, but the result was not satisfactory. Some people may ask why at the very beginning no one tried to design the H type VAWT, but фtype. The answer is so simple that a large amount of calculation work was needed for the H type VAWT which was not possible to be done without the modern computer.

    In order to meet some special needs, we started the research work on VAWT in 2001 and in the following two 2 years we made a lot of tests and improvement and at the beginning of 2003, our VAWT came into use widely in the islands and in some border regions. And it is also used in the wind-power / solar energy systems.

    At present, some companies in the world are working on the research of the VAWT.

    Following is the detail technical specification on our H type VAWT:

    1.       Technical principle:

    In according to the air-force principle and on the bases of the wind tunnel model test, the blade’s shape is of the air plane wing, which will not reduce the efficiency when the wheel is spinning which will cause the change of the blade shape. There are 4-5 blades in equal distance fixed by the connecters connecting the wheel. The wheel will drive the rare-earth metal permanent magnetic turbine to produce the power and then transfer the power to the controller.

    This technical principle is based on the slice theory. Practically the calculation will be carried out on the section of the spinning axis of the VAWT model. Note the size of the blade, take “ N “ as the spinning axis distance of each blade using CFD method to do the air-force coefficient calculation. The discrete digital method is used to get the air-force figure of the wing type section, and use the net square method to compare the reymolds member vortex flow

    Here the power is produced by using the rare-earth metal permanent magnetic material, by using the wind wheel in accordance with the hole air-force theory and by using the structure of direct driven.

    Patent No. of one kind of our VAWT is ZL200420081310.2

                                          

    2.       Power feature:

    From the principle of the H type VAWT , you will find that the speed increment of the wheel is very fast. (The increment of the moment of force increases very quickly.) So relatively the power increment is also increasing quickly resulting the nice power curve as shown in the drawing. Under the same power, the rated wind speed required by the VAWT is smaller than the present HAWT, besides VAWT can produce bigger power even when the wind speed is low.

    3.       Construction:

    Because of the usage of the special principle of hole force principle, the connecting way of triangle vector and the structure principle of direct driven, the wind   power will mainly being forced on the wheel. This is why the VAWT is strong in protecting the wind power. The another advantage of the VAWT is its noise-free and less electromagnetism disturbance.

    Attachment: Comparison on the present existing VAWT:

          Presently there are mainly two kinds of blade connecting ways:

            A: Horizontal connecting way adopted by some companies. The shortage of such way is the higher requirement on the power transfer shaft, complicated in design and more difficulty in site installation. And on the analysis, the bigger of the power of H type VAWT, the longer of the blade needed. This makes the distance between the middle point of the horizontal connection pole and the middle point of the turbine bigger which will reduce the capacity protecting the wind power. And our triangle vector is the best way to solve the above problems. (Detail comparison is shown in the attached drawing. )

    Introduction on the features( VAWT )

    Introduction on the features

     of the Vertical Axis Wind Power Turbine ( VAWT )

     

       The Vertical Axis Wind-Power Turbine ( VAWT ) is a new product designed on the scheme of wind tunnel force. We started the research on VAWT 5 years ago, almost at the same time as some developed countries in this regard. Now many of the famous experts the world –wide have accepted such new technology and this technology will definitely lead the development of the small and middle size wind-power turbines. Following are the detail features of such VAWT:

     

    Safe in operation:

         Due to the usage of the vertical blade and the force support is of triangle form, the wind force will mainly press on the wheel. So the blades will not be able to fall down, to be broken or to be thrown far away.

     

    Noise:

         The way of the turning of the blades is of horizontal and the design of the blade is of the scheme of the wing of the air-plane, so in operation the VAWT will not make any noise.

     

    Capacity of wind resistance:

         Due to the advantage of the design of the VAWT, the press force the turbine suffered is minimized and as the result such VAWT can stand on the extra strong typhoon of 45 m/s.

     

    Space requirement:

         It needs much smaller working space than other kinds of wind-power turbines. Thus not only saves the space, but also raises the working efficiency.

     

    Power curve:

         It needs lower wind speed for its starting and the increasing of the power is slow and stable. So its production capacity is 10-30% higher than other kinds of turbines.

     

    Scope of the wind power needed:

          Due to the adoption of the new control system, this VAWT is suitable to be used in the wind speed scope from 2.5 – 25 m/s.. It means we can get full use of the wind source and producing more power economically.

     

    Brake system:

          This VAWT is equipped with both the automatic brake system and the handle brake system. The handle brake system can meet the needs to brake the equipment in the area where there is no typhoon and the extra strong wind.

     

    Maintenance:

          The turbine of the VAWT is of direct driven permanent magnetic system, without using the gear box and the direction adjustment equipment, so the routine maintenance once half a year on the connecting parts of the rolling equipment will be enough.

    Research on the Extra-Size Wind-Power Turbine

                                    Research on the Extra-Size Wind-Power Turbine
     
       From the beginning of 2007, co-operated with some famous professors of Shanghai Tong Ji University, we,Shanghai MUCE Electric Equipment Co. Ltd. ( MUCE)started the research on the Extra-Size Wind-Power Turbine (ESWT).
       We, MUCE are the first researcher in such field in the world and the unit power of the ESWT is 10MW or above.
       Recently we have successfully fulfilled the first-stage research work and the result is quite satisfactory conforming to our designed requirement made on the model in according to the wind-fore fundamental.
       On the bases of MUCE resisting Vertical Axis Wind-Power Turbine (VAWT), we decided to start the research on the ESWT. We have done an extrmely careful analysis  work on each and every item of ESWT such as on the forming of the parts, the shape of the blade, wind-resistance module of the connection parts, suspension force of the spinning parts, the moment of force of the permanent magnetic turbine, the prodcuction capcity of the permanent magnetic turbine,
    the wind-resistant capacity of the whole set of ESWT and the suitability to the sea level of the ESWT and so on. And meanwhile we have also carried out the wind tunnel test on the model. The result is inspiration, not only being satisfied with the designed requirement, but also having rapidly increased the efficiency of power production. And the cost is lower than the resisting Horizontal Axis Wind-Power Turbine (HAWT).
      Our research work has been received the strong support from Shanghai Science Committee and some other government relative orgenizations which is definitely the solid foundation for our further research.
      Probaly, by the end of this year of 2007, the test on ESWT will be completed and the ESWT will come into the use.
      Such ESWT looks like a small size power mill with the designed power per unit of between 10MW and 50MW.It will be possiblly installed on the top of the buildings, along the coast area, in the shallow sea water, in the plain and at the top of the mountains and at the places wherever the wind is avaliable.
      MUCE is willing and ready to do the best efforts to dedicate the new power for the development of theworld.
      We have applied the international patent for the ESWT.
      your attention and comments will be warmly welcomed.And we will continously keep you informed about our updated progress.
      We have received the CE certificate on our VAWT.

    新型垂直轴风力发电机是如何诞生的

    MUCE新型垂直轴风力发电机是如何诞生的

        上世纪九十年代,我国的独立电源系统主要采用水平轴风力发电机和太阳能光伏系统来供应电力,主要应用于通信基站、边防哨所、海岛部队等特殊场合,主要是面向部队的一套后勤保障系统。

        经过一定时间的应用后,发现诸多问题。如台风期间的设备损坏严重;噪音大,影响人员正常休息;对通信设备的干扰,使得某些设备无法正常运转。这些问题的发生使得部队正常通讯受到了影响。

        2001年,为了解决这些问题,召集相关单位展开讨论,作为部队通信产品配套厂家的上海模斯电子设备有限公司也受到了邀请。会后,经过一定时间的调研和研究,MUCE公司提出承担此项科研攻关的重任,得到了部队领导的同意,并下达指示,必须尽快拿出技术方案并作出样机。

        在西军电、西交大、上复旦、上同济等高校一批专家的配合下,上海模斯电子设备有限公司在不到一年的时间里,就成功研制出了世界上第一台新型(H型)垂直轴风力发电机,并装机试验成功,获得了基础数据和实际经验。在后续的一年里,MUCE对产品进行无数次改进和测试,2002年底产品通过了各项测试,并达到了各项设计要求。

        2002年底至今,MUCE先后在部队安装了60多套垂直轴风力发电机和风光互补系统,为稳定国防,做出了不朽的贡献!

    新型垂直轴风力发电机(H型)设计原理

    MUCE新型垂直轴风力发电机(H型)设计原理

        针对目前众多网友对新型垂直轴风力发电机(H型)的设计原理比较感兴趣,特在此将部分设计原理以及技术指标作详细地阐述,希望能给各位朋友予以更深入地了解。

    最早的垂直轴风力发电机是一种圆弧形双叶片的结构(Φ型或称为达里厄),由于其受风面积小,相应的启动风速较高,一直未得到大力发展,我国也在前几年做了一些尝试,但效果始终不理想。针对一些朋友问及:为何当初采用Φ型设计而没有用现在这种H型结构?实际上,这和科技的发展特别是电脑的发展密切相关的,由于H型垂直轴风力发电机的设计需要非常大量的空气洞力学计算以及数字模拟计算,采用人工的方法计算一次至少需要几年的时间,而且不是一次计算就能得到正确的结果,所以在计算机还不是很发达的年代,人们根本无法完成这一设计构思。

    由于特殊应用场合的需要,2001年我国率先开始了这项研究,并且在以后两年的时间里不断对产品进行改进,在2003年初,产品走向成熟,并在海岛以及边疆大量采用以这种新型垂直轴风力发电机为主要设备的风光互补系统。

    目前,世界上主要以MUCE公司和日本某公司为该产品的主要研发和生产单位。

    下面我就详细讲解一下H型垂直轴风力发电机的技术原理:

     

    一、技术原理

    该技术采用空气洞力学原理,针对垂直轴旋转的风洞模拟,叶片选用了飞机翼形形状,在风轮旋转时,它不会受到因变形而改变效率等;它用垂直直线4-5个叶片组成,由4角形或5角形形状的轮毂固定、连接叶片的连杆组成的风轮,由风轮带动稀土永磁发电机发电送往控制器进行控制,输配负载所用的电能。

    该技术原理根据空气片条理论,实际计算可选取垂直风机旋转轴的切面进行计算模型,按叶片实际尺寸,每个叶片的旋转轴心距离为N米;用CFD技术进行模拟气动系数计算,计算原理采用离散数字方法求解翼形断面的气动力,用网格方法对雷诺数流动涡量分布比较形成高雷诺数下对Navier-Stokes方程进行数字模拟计算的原理结果。

    采用稀土永磁材料发电的原理,配套与空气洞力学原理的风轮,采用直驱式结构进行旋转发电。

    专利技术:一种风力发电机(专利号:ZL200420081310.2

     

    二、功率特性

    根据H型风力发电机的原理,风轮的转速上升速度提高较快(力矩上升速度快),它的发电功率上升速度也相应变快,发电曲线变得饱满(如下图),同样功率的额定风速较现有水平轴低,在低风速运转时发电量也较水平轴大。

    点击看大图 

     

    三、结构

    由于此种设计结构采用了特殊的原理,风轮的受力主要集中于轮箍上,因此抗风能力较强;此种设计的特性还体现在对周围环境的影响上,运转时无噪音以及电磁干扰小等特点使得新型垂直轴风力发电机优越性非常明显。

    附:现有垂直轴风力发电电源比较:

     

    目前,生产该类型垂直轴风力发电电源系统产品最多的是日本(2002年开始研究),还有英国、加拿大等国也在研制中,产品在风轮设计当中采用平行连接杆,这种方式对发电机输出轴要求高,并且结构相对复杂,现场安装程序多且较不方便。从力学方面分析,功率越大,叶片越长,平行杆的中心点与发电机轴的中心点距离越长,抗风能力越差,对此,我们采取的是三角形向量法,弥补了上述的缺点(具体比较见下图)。

        在经历了多年的努力后,新能源路灯已被越来越多的人认可和应用,市场出现了欣欣向荣的局面。作为我们这一批新能源的开拓者,是否真正考虑过这些问题:我们的新能源路灯已经在技术上成熟了么?不同区域的新能源路灯我们如何进行合理配置?

        在政府大力提倡节能减排的今天,给新能源的发展注入了巨大的动力,各级政府以及企业为了完成减排指标,花费大量资金和人力投入到新能源中。最近,在工作中接触到一些采用过新能源路灯的客户,他们的抱怨让我感到吃惊,故障率高、噪音大、灯光亮度低、人为损坏严重、维修不及时等都是较为严重的问题。这里边涉及到技术、设计、安装等多个环节,有些客户甚至提出以后再也不敢用新能源路灯了。

        也许有些同行已经对此习以为常了,但我们必须重视这些问题,因为一旦政府部门对这项产品失去信心,我们将会迎来市场的寒冬。

        对于以上这些问题,我谨在此表述一下个人的观点:

    一、在技术上我们可以采用垂直轴风力发电作为发电主体,它有这么几点好处:1、故障率低(转速慢、无转向机构);

    2、无噪音;

    3、发电曲线饱满(启动风速低、在中低风速运行时发电量较大);

    4、不受风向及近地面团风的影响;

    5、抗台风能力较强(抗风能力达到45m/s)。

    二、在设计上我们采用几种较为合理的形式:

        1、风光互补路灯配置: 垂直轴风力发电和太阳能电池板以103的配比进行设计,适用于大多数城市道路。

           例如10米高路灯配置:  灯笼型垂直轴风力发电机--300W 
                                  
    太阳能电池板--75W
     
                                  
    灯杆高度--10米;
     
                                 
    灯泡功率--75陶瓷金卤灯或120W无极灯
     
                                 
    蓄电池--100AH免维护;
     
                                 
    亮灯时间--10h/d

      2、单纯风力发电路灯配置: 垂直轴风力发电机单独供电,适用于海边及风力资源较好的城市道路。

        例如10米高路灯配置:    灯笼型垂直轴风力发电机--300W 
                                 
    灯杆高度--10米;
     
                                 
    灯泡功率--75陶瓷金卤灯或120W无极灯
     
                                 
    蓄电池--100AH免维护;
     
                                 
    亮灯时间--10h/d

       3、蓄电池配置:蓄电池采用胶体蓄电池,安装在路灯灯杆中间,既作为蓄电池箱同时可用作广告灯箱。胶体蓄电池寿命较长,工作稳定性较高。

       4、控制系统:风光互补控制器或风力发电控制器对于蓄电池的充放电控制非常关键,必须将其控制在较平稳的变化范围内。控制器的好坏对于蓄电池以及光源的寿命起到至关重要的作用。例如:常用蓄电池一般寿命在2-3年,采用高稳定性控制器,其寿命可达到5-8年。

      5、光源:一般采用陶瓷金卤灯,无极灯虽然比较节能,但是到一定功率后必须采用交流电,存在一定功率损耗,增加了易损电子元件。而且无极灯由于含汞,对今后的处理是个环境隐患。对于现在很多人提出的采用LED作为路灯照明光源,现在时机还未成熟,LED由于其眩光值较高,在现有的道路验收标准未改变的前提下,无法通过最终验收,对于道路安全性也是一个隐患。

     6、太阳能电池组件:我们一般认为单晶硅太阳能电池具有光电转换效率高的特点,故一般都喜欢采用它。其实对于新能源路灯而言,由于其独立供电,供电持续性要求较高,故采用弱光性较强的多晶硅太阳能电池效果较好。(注:两者差异不明显)

    三、维修保养

       1、由于采用了新型设备,维护保养变得相对简单,只需定期对设备表面进行维护。

       2、在设计时就考虑到检修的方便性,在控制器内部设置预留检测端口,可由使用方采用专用设备进行检测,更换故障点设备。

    总结:对于新兴行业,我们要敢于探索,不断进行技术的革新,最终找到真正适合的方案,这是对市场负责,也是对我们自己负责。

          我们将秉承科技是第一生产力这一宗旨,为经济的持续发展提供源源不断的动力!

    未来新能源如何在现实中应用-MUCE风光互补系统

    未来新能源如何在现实中应用-MUCE风光互补系统

          随着能源危机日益临近,新能源已经成为今后世界上的主要能源之一。其中太阳能已经逐渐走入我们寻常的生活,风力发电偶尔可以看到或听到,可是它们作为新能源如何在实际中去应用?新能源的发展究竟会是怎样的格局?这些问题将是我们在今后很长时间里需要探索的,我谨以个人观点表达如下:

          新能源(或称可再生能源更贴切)主要有:太阳能、风能、地热能、生物质能等。生物质能在经过了几十年的探索后,国内外许多专家都表示这种能源方式不能大力发展,它不但会抢夺人类赖以生存的土地资源,更将会导致社会不健康发展;地热能的开发和空调的使用具有同样特性,如大规模开发必将导致区域地面表层土壤环境遭到破坏,必将引起再一次生态环境变化;而风能和太阳能对于地球来讲是取之不尽、用之不竭的健康能源,他们必将成为今后替代能源主流。

          太阳能发电具有布置简便以及维护方便等特点,应用面较广,现在全球装机总容量已经开始追赶传统风力发电,在德国甚至接近全国发电总量的5%-8%,随之而来的问题令我们意想不到,太阳能发电的时间局限性导致了对电网的冲击,如何解决这一问题成为能源界的一大困惑。

          风力发电在19世纪末就开始登上历史的舞台,在一百多年的发展中,一直是新能源领域的独孤求败,由于它造价相对低廉,成了各个国家争相发展的新能源首选,然而,随着大型风电场的不断增多,占用的土地也日益扩大,产生的社会矛盾日益突出,如何解决这一难题,成了我们又一困惑。

          早在2001年,MUCE就为了开拓稳定的海岛通信电源而开展一项研究,经过六年多研究和实践,终于将一种成熟的新型应用方式MUCE风光互补系统向社会推广,这种系统采用了我国自主研制的新型垂直轴风力发电机(H型)和太阳能发电进行103地结合,形成了相对稳定的电力输出。在建筑上、野外、通信基站、路灯、海岛均进行了实际应用,获得了大量可靠的使用数据。这一系统的研究成果将为我国乃至世界的新能源发展带来了新的动力。

          新型垂直轴风力发电机(H型)突破了传统的水平轴风力发电机启动风速高、噪音大、抗风能力差、受风向影响等缺点,采取了完全不同的设计理论,采用了新型结构和材料,达到微风启动、无噪音、抗12级以上台风、不受风向影响等性能,可大量用于别墅、多层及高层建筑、路灯等中小型应用场合。以它为主建立的风光互补发电系统,具有电力输出稳定、经济性高、对环境影响小等优点,也解决了太阳能发展中对电网冲击等影响。

          我们将秉承科技是第一生产力这一宗旨,为经济的持续发展提供源源不断的动力!

    垂直轴风力发电机的发展历史-MUCE

    MUCE垂直轴风力发电机——使风电建筑一体化成为可能

     

          风力发电和太阳能发电一样,最初是为了解决应急电源和边远地区供电而开发出来的产品,因而在最初发展并不是很快。

          到了上个世纪二、三十年代,全球经济危机带来的能源紧张,让世界各国的专家想到了以风力发电作为补充能源的可行性。第二次世界大战后,各国纷纷进行研究,由于当时的技术水平较差,启动风速要求较高,发电噪音也很大,所以只能将风力发电机放在人迹罕至的地方或风力较大的地方。设备也是往大型风力发电机发展,专门建设大型风力发电场,由于水平轴风力发电机的特性,小型风力发电在相当长的时间里未得到较好的发展。

          现在,各个发达国家均大力发展新能源产业,而太阳能一直是新能源商业化的首选,因为太阳能的设置地点较灵活,不会产生噪音,可以和建筑进行一体化设计。而风力发电较太阳能而言,它的成本优势明显,如何使得风力发电和建筑进行一体化设计、在建筑周围设置小型风力发电机而又不影响人的生活质量,这成为了欧美一些国家研究的焦点!

    2001年我国率先开始了新型垂直轴风力发电机的研究,由部队牵头,上海模斯电子设备有限公司为研发主体,西安军电、西安交大、同济大学、复旦大学等高校的多位专家配合,在短短的一年时间里就生产出了世界上第一台MUCE新型垂直轴风力发电机。并在5年不到的时间里将功率扩展至200W--100KW,处于世界领先地位。

          世界上其他国家也都进行了新型垂直轴风力发电机的研制,日本在2002年初开始研究,2003年初产品投放市场,功率在0.5--30KW之间。美国、英国、德国、奥地利、韩国等国家也都在去年已生产出样机,准备投入规模化生产,目前功率都在20KW以内。

          MUCE在将垂直轴风力发电机功率提升的同时,始终坚定不移的开发风电建筑一体化市场,在大连、上海的高层商务楼上进行设计。预计在2008年底前成功推出风电建筑一体化项目。

          另外,风光互补系统作为新能源的一种搭配方式,MUCE在部队经过五年的应用后,认为这种新能源供应方式具有良好的供电持续性、并网时电网冲击小、离网时蓄电容量小等优点,因此这将是新能源应用的大方向!

      随着能源危机日益临近,发展新能源已经成为世界各国的不二选择。在众多新能源中,风能和太阳能对于地球来说是取之不尽、用之不竭的健康能源,他们必将成为今后替代能源主流。太阳能已经逐渐走入我们寻常的生活,风能作为一种清洁的可再生能源,也越来越受到世界各国的重视。上海模斯电子设备有限公司是一家拥有多项高新技术的高科技企业,在新能源以及通信领域具有国内领先的技术和实力。万国商业网编辑有幸采访了公司销售总监陆剑洲,他畅谈了作为新兴的风力发电行业的企业是如何在不成熟的市场中茁壮成长的。



    上海模斯电子设备有限公司销售总监 陆剑洲

      万国商业网:请您介绍我们一下公司的基本情况。

      陆剑洲:上海模斯电子设备有限公司原先是给部队做通信的配套产品,200111月份,我司受部队指示,为保证开发边、防哨所连队通信及生活用电,公司技术人员开始研制垂直轴风力发电机和风光互补电源系统,在研制过程中得到了西安交大、同济大学等高校的专家的协助,于2002年底研制成功第一台样机。2003年初开始将垂直轴风力发电机装备进部队,5年来共计安装60多套风力发电机组及风光互补发电系统,在各种恶劣环境的考验下运行稳定、系统可靠,为此获得了解放军科技进步三等奖、上海市高新技术成果转化项目。在企业发展的5年多里,95%的产品都是供应给部队的,去年年底才开始推向市场,今后的市场主要是国外,目前,产品已发往欧洲、澳洲、东南亚等国家和地区。

      万国商业网:垂直轴风力发电机的产品特点是什么?

      陆剑洲:公司目前生产的专利产品垂直轴高效率风力发电机组 FDM 型号,功率从200W—100KW,它的风轮与永磁发电机和盘式发电机配套,先进的永磁发电机组具有启动力矩小、效率高等优点,最高效率可达 85% ,垂直轴永磁式风力发电机组比普通的高 15% 18%。垂直轴风力发电机组性能特点:发电效率高、无噪音、低风速发电、抗风能力强、不绞电缆线、外形美观、机械和电器制动保护、恶劣环境运行、行使物上正常运行(船)、受风无方向性。

      万国商业网:您认为模斯的竞争优势是什么? 

      陆剑洲: 我们在这个行业的时间比较长,差不多有6年时间了。2001年我国率先开始了新型垂直轴风力发电机的研究,由部队牵头,我们公司为研发主体,西安军电、西安交大、同济大学、复旦大学等高校的多位专家配合,在短短的一年时间里就生产出了世界上第一台MUCE新型垂直轴风力发电机。并在5年不到的时间里将功率扩展至200W--100KW,处于世界领先地位。其他国家也都进行了新型垂直轴风力发电机的研制,日本在2002年初开始研究,2003年初产品投放市场,功率在0.5--30KW之间。美国、英国、德国、奥地利、韩国等国家也都在去年已生产出样机,准备投入规模化生产,目前功率都在20KW以内。但我认为他们的产品还没有经过时间的检验,新型垂直轴风力发电机是刚研制出来的新技术,它在生活上的应用要不断的经过实践和改进,方能发展成熟,这需要一个很漫长的过程,我们的优势就在这里,我们已经经历了这个过程。

     万国商业网:作为行业人士,您如何看待国内风力发电行业的发展?风电行业的发展有什么阻碍因素?

      陆剑洲:我曾经从事过太阳能发电行业,以前我认为以后新能源的发展以太阳能为主,后来发现这种观点是不正确的。其实太阳能与风能都是新能源的主要发展方向,太阳能发电具有布置简便以及维护方便等特点,应用面较广,但太阳能发电的时间局限性导致了对电网的冲击,风力发电技术的成熟,正好弥补了太阳能发电存在的缺陷。
      
      
     目前风能行业的发展急需解决的问题是设置地点的问题。现在,太阳能之所以一直是新能源商业化的首选,各个发达国家均大力发展,是因为太阳能的设置地点较灵活,不会产生噪音,可以和建筑进行一体化设计。而风力发电较太阳能而言,它的成本优势明显,如何使得风力发电和建筑进行一体化设计、在建筑周围设置小型风力发电机而又不影响人的生活质量,这成为了欧美一些国家研究的焦点!例如在中东,那边比较富裕,他们做了很多风力发电厂,之前在某个世贸中心的两栋大楼之间做了三台大型风力发电机,这是世界上独创的,但此项技术没有可推广性。今后的风力发电建筑一体化必定是采用垂直轴的形式。

      万国商业网:像咱们这种有知识产权的产品,它的原材料是自己研发的还是从别的渠道获得的?



    风光互补路灯

       陆剑洲:现在所有的基础技术都是我们自身研制的,目前已拥有6~7项专利了,并以每年研制2~3项专利的速度在增长。

      万国商业网:要促进企业有新的发展,您觉得公司还要在哪些方面做进一步的完善?公司未来的发展远景是什么?接下来有什么发展计划?

      陆剑洲:接下来我们要在风能发电应用方式的拓展作努力,以前的应用方式涉及的面比较狭窄,只是用于边防部队的通讯或者特殊的场合,我们现在想扩大到民用方面,比如将风能发电机与普通的别墅、办公楼、商务楼等各种各样的建筑相结合,这个在国内不普遍,我们始终是在做开拓;另外,我们要做批量化生产。这是我们要完善的两个方面。我们也希望有机会与从事太阳能的相关企业一起合作,尤其是想与大的公司进行合作,因为规模化生产这种产品需要比较雄厚的资金。
     
      万国商业网:作为一项世界的新课题,你们在没有任何前人经验的情况下,自我探索,不断开拓,祝愿你们发展顺利,最终成就中国的骄傲!

      陆剑洲:谢谢!

      公司发展历程:

      2001年上海模斯电子设备有限公司接到解放军通信部指示,开始研制垂直轴风力发电机和风光互补系统;

      2002年底就研制出了世界上第一台新型垂直轴风力发电机,为我国风力发电机的自主开发奠定了良好的基础。

      在后续的几年里,公司为边防部队提供了60多套垂直轴风力发电和风光互补系统,功率在300--50千瓦,系统运行稳定,经历了各种恶劣气候的考验。

      2006年初,在解放军某研究所的认定下,此系统获得了解放军科技进步三等奖。同时,获得了国家发明专利以及上海市高新技术成果转化项目。
    2006
    年底,公司顺应时代的发展及政府号召,将此项技术应用于民用领域。很快获得了国外市场的追捧,在半年多时间里,产品已销往英国、法国、德国、罗马尼亚、奥地利、澳大利亚等国家。公司所有产品均已获得了CE认证。

      在经历了5个年头后,在今年试制成功100千瓦垂直轴风力发电机,在世界新型风力发电的舞台上展露了中国企业的风姿,站在了世界的最前沿。
