Vertical Axis Small Wind Turbine Breakthrough and Small Wind Turbine Application Limit
Jacken Chen, General Manager
Hi-VAWT Technology Corporation [email protected]
Abstract
In the attempt to reduce the global warming effect, small wind turbine (SWT) is expecting to play more and more important role in the upcoming future. The traditional small wind turbine technology has been dominated by Horizontal Axis Small Wind Turbine (HASWT) for decades. However, the noise nuisance and the questionable practical power performance have been reported in two key problems of the traditional HASWT which limits SWT application very much.
Vertical Axis Small Wind Turbine (VASWT) is considered as a good solution to overcome the noise nuisance of SWT application. Whereas, it is reported that VASWT has problems of either failure of self-start or poor power performance. The industry is looking for a good VASWT to expand market of SWT.
Biography
Jacken Chen is a founder and general manager of Hi-VAWT Technology Corporation (Hi-VAWT), a company specializing in the design and manufacture of VASWT since January 2005. The unique design of Hi-VAWT’s VASWT accomplishes excellent low wind self-start and high power efficiency. Hi-VAWT has been selling the products successfully in Europe, UK, Korea, Taiwan and China; and is expecting to develop market sale in USA market starting year 2010.
Jacken Chen accomplished his bachelor degree of Chemical Engineer in 1979 at Tatung University in Taiwan. He started his first job career in Taiwan as sale representative of Freon* products for Dupont company. Many years later, Freon* products was under global control because of ozone depletion problem; he established his own company involved in mechanical, electronic and textile business for several years. In January 2005, Jacken decided to organize a company namely Hi Energy Technology Co., Ltd. for R&D and production of VASWT. Later on, the company decided to change company name as Hi-VAWT Technology Corporation in October 2009 in order to keep away from any possible similar name conflicts with some other companies in USA and Italy.

• Power cost of SWT is 20 times more than LWT and 60% more than SWT; but PV market is larger.
• SWT market is only 1% around of PV • SWT is confined to use in rural area which market is small.
Why?
Centralized Power Concept• Power plant of billions watts power
generator operated by professional team.• Supply power through grid network which
is huge infrastructure investment• Nuclear and gas power plants are
traditional examples. LWT is the representative example of clean energy.
Distributed Power Concept• Small scale power generator for self power supply and operated by amateur
people.• Power generator should get close to the user so as to reduce the power loss
during power transportation.• Diesel generator is an example of traditional power. PV and SWT are the
choices of clean energies.

HASWT Design Fails To Handle Geographic Turbulence Problem Of SWT

It is 45 (dB) even the HAWT is 300 meters away
Noisy Nuisance Of HASWT Makes It Unacceptable for Suburban Installation
Europe applied 45dB noise standard started Jan. 2009; USA & Canada will follow soon. Conventional HASWT is unable to fit the requirement
45dB Noise Limit For SWT Is Becoming International Standard
HALWT vs.
HASWT
Wind Direction Problem:• LWT is using anemometer to assure wind direction has been change and drive
servo motor to rotate wind turbine toward the correct wind direction. LWT is not sensitive to the random wind direction change.
• SWT designed with tail which expected to trace wind direction directly; but it results that SWT has been too much sensitive to the random wind direction change.
Noise Problem:• LWT is operating at rated 12~20 rpm; the noise is acceptable.• SWT is operation at rated 500~1,200 rpm; the comparatively high rotor speed
results in very high noise.

Citizen Group Requests An Audit for “Unmoving” Wind TurbineSwaying “Dream Project” – Ibaraki PrefectureFor the Tsukuba-City’s “Mahoroba Project”, which plans to install totally 75 units of small typed wind power turbines in 52 elementary and junior high schools in the city within 3years from the year 2004, city group members stood up for making an audit request against the Mayor Kenichi Ichihara calling for a reimbursement of the project expense of pprox. 300million yen for the reason that such the sufficient power generation as expected in the target will be hardly achieved. “Dream project” which is said to have two ideal aspects of environmental education and reduction of electricity consumption is now widely swaying around.
After the investigation by the city group, however, total generation while the turbines operated from July to November last year was only 103kWh, which is only 0.002% of the planned 60,000kWh.

Global SWT MarketIs Going To Takeoff Right Now
WP Target OF EU4% In Year 2008 To 30% by Year 2030
EU Regulated 20% of the residential power should use renewable energies by year 2020; both SWT and PV are encouraged.
How can we get away from petroleum energy?
SWT Market in UK Has Grows in Average 2~3 Times Annually
BWEA forecast 60 millions British pounds by year 2009
‧ Starting Feb. 2009, USA Federal government offers 30% tax rebateincentive for SWT. The incentive program of SWT is same as PV.
‧ USA SWT market grew by 73% in year 2008 and market sale was US$77 millions; AWEA forecasts USA SWT market will become 20 times bigger by year 2013 or US$16 billions annual sale.
‧ SWT standard including noise regulation will be published in late June 2009 and effective to apply in year 2012.
