in order to show the difference with conventional Wind generator we use an excellent existing turbine :the Nordex 1.5 MW 77m.

This turbine like all wind generator of same type, targets a specific power rating and once it reaches it at about 10-12 ms will deliver the same power until wind is too strong and they need to be shut down.

Motorwind does not have the same objective as the generators can still increase their power output until 80 ms.the chart shows a stop at 55 ms but it can still go higher.

The main concern of traditional wind generator is to deliver to the grid a quality output within the specifications of the Grid owner in terms of frequency and voltage level.

We do not have the same problem as we generate DC current and use external inverters

that guarantee the quality of power output.

we have used in this example Motorwind 150000 which means 150000 Microturbines.

as we know very well the capacity of one generator, then the total power output is simply 150 000 times stronger.

The rating of Motorwind 150000 is 28.5 MW at 55 ms wind speed but as we can see the performances are very close to the Nordex S77 until it reaches its top power .

We can see the best case is when there an average of low wind speed and few typhoons a year which exist in many areas of the world .Typhoon / hurricane area are not very windy area in general .

Typhoon Off shore wind farm :

Usually Motorwind installation are not directional because the turbines are symmetrical so they can work from both directions and usually wind direction is very stable.Winter from North and Summer from South -South East.

For typhoon turbines it is different as wind direction changes within few seconds and general direction changes as the hurricane /typhoon moves across the water or land .

for Northern Hemisphere Hurricane /typhoon the wind move anti-clockwise around the center so depending on relative distance between the eye of the storm and the turbine wind direction can vary greatly.We therefore make the panels, wind tracking (only 90 degrees), so they can adapt quickly.

Example:if the eye is 10 km in diameter and the typhoon is moving at 20kmh in West direction then within 1/2 hour the wind direction will change from North to South (assuming the eye will pass on top of the turbine) .

triangular Unit size: 30 m W x 80m H.

Conventional wind generator can only have a single pole because they need to rotate around .Microturbines do not have this restriction and therefore more lighter and stronger poles /structures can be used.

Schematic of one panel

The panels are 12 m in width and 6m high . they can be handled easily and they also can move freely from the other panels so they can adapt to the different wind conditions at different hight.it also decreases their moment of inertia so the response time is faster.

each panel is only 72 square meters and weights only 1.3 ton so as per our philosophy we can install as many panels as necessary to collect the energy that we need.One panel being made of 760 turbines can generate 144 KW at 55ms and still can generate approx 5 KW at 10 ms.

For offshore wind farm, such structure does not need anchoring in sea bed.

with a span of 60m and a height of 100 m(80 m above sea level) and with a total weight of :approx 300 tons it cant tilt over or move under wind and wave pressure.(210 tons for the structure and 90 tons for the turbines)

By design the more turbines and structures are added the more stable it is .

Anchoring is a very important part of the cost (time and US$) in offshore turbines. Usually thousand of tons of concrete are poured in the sea bed to make the tower strong enough.

It can take weeks /months of drilling and piling in the sea bed to install one tower with very heavy machines that disrupt the sea life for ever.

With Motorwind turbines there is no need for that.

Remark 1: for conventional turbines the blade orientation is crucial for a good efficiency and they have developed Pitch control systems.

For Motorwind turbines due to the design of channeling wind trough a tube (force flow) the direction or quality of wind is not as crucial so it offers more flexibility.

Remark 2:Since there is nothing to control in our structures, generators are connected inland with a serie of cables and all regulations and control and batteries and inverters are inland which makes it much easier to intervene and take action.Each panel cable is brought inland so each panel can be either connected or disconnected and monitored to detect any problem.

Remark 3: Since Motorwind microturbines can make logos and images an important part of the financing can be through advertising.

Remark 4:each single turbine is actually a very good wind meter since wind speed and Voltage output is linear and we have an accurate chart.by monitoring the voltage output from each panel we actually know the exact wind speed per panel.it is important because the wind speed is not the same at 20m above the surface and at 100 meters.The total output of the whole system is an aggregation of multiple outputs at different wind speed.

 

first panels developped in 2009 are the base of today's development
