Today our post is about Advantages and disadvantages of vertical axis wind turbine. Vertical axis wind turbine are one whose axis of rotation is vertical with respect to ground. There are many Advantages and disadvantages of vertical axis wind turbine but we have discus few of them
Advantages
Advantages
- They can produce electricity in any wind direction
- Strong supporting tower in not needed because generator, gearbox and other components are placed on the ground
- Low production cost as compared to horizontal axis wind turbine
- As there is no need of pointing turbine in wind direction to be efficient so yaw drive and pitch mechanism is not needed
- Easy installation as compared to other wind turbine
- Easy to transport from one place to other
- Low maintenance cost
- They can be install in urban area
- Low risk for human and birds because blades moves at relatively low speed
- They are particularly suitable for areas with extreme weather conditions, like in the mountains where they can supply electricity to mountain huts.
Disadvantages
They are only less efficient with some (poorly designed) blade designs. There are many models that do not have much drag going into the wind, and in some cases some have wings that get more power going into the wind.
ReplyDeleteThis article seems to only talk about one particular style, that is over 50 years old... There has been a lot of improvements in the last 50 years.
Yes you are right there are many improvements made in VAWT but whenever we begin to learn we start with basic. This is my beginning with wind turbine and with the agrce of ALLAH (GOD) we will learn all the new points of VAWT from my blog
DeleteThanks Mongrel shark for such sincere comment
I am an engineering student. Please contact me as soon as possible via email (karim_hatem72@yahoo.com) because i need help. I am working on VAWT as my degree project.
ReplyDeleteOk, I have your request listed, I will contact you in one or two days. Thank you for contacting us.
DeleteHello sir, This is Karthik from chennai, India. I'm an Mechanical Engineering student. As a part of academic curriculum, we are doing a project on VAWT. I kindly request you to help us in solving the problems associated with the design and analysis
ReplyDeletewill three blade topology would not make it self starting or it will still need an external push. kindly reply.
ReplyDeleteRegular three blade VAWT design will not be self starting but with magnetic bearing and advance design they can be made selfstart
Deletehello sir am working on VAWT AS MY FINAL YEAR PROJECT was requesting to know whether there is any upgrade i can do on the recent maglev wind turbine my email is collinsmugacha@gmail.com
ReplyDeletedepends on the design of your vawt assembly (design). I improved and made a bit modification on my vawt design. And it doesn't have too much drag and friction. extremly smooth as silk.
ReplyDeleteHAWT is always more efficient when compared With VAWT because all blades can generate power at a time in HAWT
ReplyDeleteHAWT is more effiecient compared to VAWT no matter how many improvements have been done in the last 30years or so.
