Smart Wind Turbine

Smart Horizontal Wind Turbine:The horizontal-axisturbine typically has a three-blade vertical propeller that catches the wind face-on. To work properly, the horizontal-axis turbine needs the wind to flow at a right angle to the blades. If it blows from a different direction than the blades are facing, the turbine gets much less energy from the wind. To accommodate changes in wind direction, the turbine has a yaw drive that rotates the unit’s direction. However, the drive adapts slowly to changing directions because it must turn the entire turbine and propeller assembly. We can supply in many size starting from model AR-100W to AR-30KW

Smart Vertical Wind Turbine: The vertical turbine has a set of blades that spins around a vertical axis.Vertical turbine runs well regardless of wind direction, making it better-suited to urban areas with tall buildings where wind turbulence is a given. The vertical-axis design allows it to operate on lower wind speeds than is possible with the horizontal turbine. We can supply size only in two models at present VAR-120W and VAR-1000W.

We are providing you with the details of the turbine size, installation and maintenance manual with price list.

CALCULATED POWER CURVE FOR 2KW- 5KW-7.5KW – 30KW

SITE SELECTION SITE IS IMPORTANT TO EFFICIENCY AND SAFETY OF WIND TURBINE.

A good location needs 2 basic conditions

High average wind speed

Low turbulence

The energy we can take from the wind is proportional to the cube of its speed. This basically means that when the wind doubles its speed, the power we can produce is up to 8 times higher.

Therefore, the best site to install a windmill will be a place where it is exposed to the most constant and highest wind speed possible. The wind speed depends enormously on the landscape the air moved over. In almost all locations the wind speed increases, as you get higher off the ground, vegetation, landscape, nearby buildings etc. stop the wind and produce turbulences.

Please read Annex III – for more details about this.

Tower (Pole) installation

The anchoring of the tower will depend on the kind of tower you will be using. The foundation for the self-standing towers is very important, and for the tilt-up tower is just to avoid it sinking on the ground. For both cases, check that at all moment the tower remains totally vertical.

If your tower is not strong enough, you must reinforce it using guy ropes. If the ground is not strong, remember to use a correct size for basements. Check that, at all time your tower remains perfectly vertical.

For Lattice type tower will be installed at site based on the numbering of each member. Each model foundation drawing will be very depends the soil property. It is good to have soil test report before going foundation.

Lattice Tower

The guy ropes take all the bending moment of the tower. They therefore must be 6-10 mm diameter steel cables. Attach the guy ropes the highest on the tower but always beneath blades diameter. Grounding the tower will provide static and lightning protection for the system. This can be made driving cooper wire into the ground near the tower base and connecting it to the tower with wire. You must absolutely make sure that no object could possibly reach the blades, and that any other parts of the windmill touch any other moving part. Allow a minimum distance of 20cmbetween the blades and the tower.

CAUTION

The windmill must be able to

turn 360° freely with no

Obstacles in its way.

 
 

WARNING

Any object touching the

blades moving, will break

them and will damage the

system causing major

Problems.

INSTALLING THE WIND TURBINE

Installation Procedure:

 

To easily install the wind turbine on the tower, a bracket and pulley system should be used.

This system must securely attach to the tower, with the pulley on top. Using this method, the turbine can be hoisted up and secured while the electrical connection is completed and the turbine is fitted to the tower.

Make sure all of the other electrical connections are completed before attempting to electrically connect the turbine to the system.

           BRACKET AND PULLEY SYSTEM                                                                   Yawing (Fixation) Plate

Yawing (Fixation)Plate: This plate is provided to be attached to the tower. Another one is assembled on the wind turbine base. Its function is holding the wind turbine, offering an easy way to install it and take it down from the tower at any moment.

* The bolts set and tower plate are served in an independent plastic bag, if not mailed before.

 

Tail

The tail is made to keep the windmill facing into the wind at any time. The tail is made of 2 different pieces:

- A fiberglass vane

- Steel Frame

*This is usually already assembled and delivered in the box

Tail vane with Alternator

The tail is attached to the alternator Frame at this point. Before bolting the vane to the alternator, pass the body shroud through the tail vane. (Once the vane is bolted, you will not be able to install the nacelle (nose cone)).

This joint has 2 different systems to secure, one has a bolt going through the vane, and the other one is a bridle system. We first introduce the tail vane into the backside of the alternator, and make coincide the holes in both pieces.

6.5 Nacelle The nacelle protects the alternator from the external climatologically agents. The nacelle is attached with various bolts, used in top, back and underneath sides.

The assemble order is:

 

- bolt, grower washer and wide washer the next bolt is to secure the one in the back.

Blade with Hub Unit

The blades, made out of fiberglass reinforced, are the part directly in contact with the wind. They are highly stressed. Their aerodynamics, specifically designed for USCET wind turbines, makes the alternator turn faster or slower depending on wind speed.

That assemble them to the hub according the numbering on the Blade flange, we have to place them with the set-off logo facing back, and this is facing the tail.

Charge Controller

The Charge controller is protects the batteries from high voltage. Any electric generator that can over exceed the batteries voltage requires a charge controller. The correct use of the proper charge controller is critical to good performance and long life of the battery system.

The controller continuously monitors the battery voltage and controls the current through the batteries. It allows the optimum charge to the batteries when they are low and diverts the charge to a dump load when they are fully charged. This dump load is installed within the charge controller and can be fitted with an optional water heater output.

The charge controllers USCET wind turbines use, have been specially designed to work with our machines, and solar panels in hybrid cases.

 

The charge controller is provided with the following connectionswitches:

  • 3 phases input from the wind turbine.
  • Solar panels input +/- (Optional)
  • Batteries output +/-
  • Water heater output (Optional)
 

The charge controllers are equipped with a red led. This led will be on when the batteries are fully charges and the electricity is being driver to the dump load. They are equipped, as well with a voltmeter and an amp meter to measure the electricity that is being produced at all times.

Do not connect any other electric element between the wind turbine and charge controller OR between the charge controller and the batteries, serious damage could occur.

On the left side of the charge controller, there is a break switch. This switch

short-circuits the alternator increasing the torque required to turn the rotor, thus slowing the turbine down. When this happens, the torque to make the alternator turn is much higher, this acts as a brake.

In high wind speeds, the blades turn very fast, the braking force of the brake switch may not immediately stop the blades of the turbine. It if continues rotating, turn the brake switch on and off repeatedly until the blades stop. Each time the switch is activated, the blades will slow until the force of the brake sufficient enough to lock the blades in position. At this point the turbine will not start until we switch the break off.

 

ELECTRIC CONNECTION

If an external load is going to be used, connect the load where indicated before continuing with the rest of the connection. If not, the regulator is present with an internal load, son no changes need to be made.

If the system will be used in conjunction with solar collectors, these must also be connected electrically prior to connecting the regulator and the battery. The regulator will be marked as a

HYBRID REGULATOR on the side and will specify the maximum allowable amp rating for the solar collectors that can be connected. Never invert the polarity of the solar collector cables to the Charge controller and never connect collectors which exceed the maximum amp rating of the charge controller.

Charge controller to Battery connection:

 

First, connect the positive and negative cables from the battery to the corresponding inputs on the charge controller box.

Next, connect, the 3 cables from the wind turbine. The electricity from the wind turbine is alternating 3 phase, so there are no polarity issues and the cables may be placed in any order.

In order to minimize the losses in the wiring, the distance between the wind turbine and the regulation box must be as short as possible. Never more than 100 meters, Also, the charge controller, batteries and inverter should be installed in the central point close to where the electricity is going to be distributed, again to reduce the electrical loss in the wiring.

The cable diameter depends on the wind turbine model and the distance to the control box, check table in the Annex II to calculate.

The control box has to be installed approximately 1,5 m over the ground level, and a minimum of 50 cm from the batteries to prevent contact with the gasses they produce.

In a hybrid installation, with the water heater option, the installation could be as in the next figure;

Once everything has been finally connected, including the battery bank, check if the electric installation has been done right, by running manually the alternator, and reading in the control box displays, if there is an output. If there is no output, check all the connections and recheck until everything is ready to work.

CAUTIONS

Do not manipulate the windmill and its control panel on windy days

Do not leave the wind turbine run freely (Disconnected from the batteries), this could damage the charging system. If you need to disconnect the wind mill from the batteries, always brake it.

With the wind mill turning freely, the automatic breaking system does not work, that could cause irreparable damages in your wind turbine.

Do not manipulate the loads in the charge controller

Do not invert the polarity in any case

 

Use the appropriate wiring

MAINTENANCE

 

After the Installation

One month after the installation of the wind turbine, we recommend checking that the bolts have the right torque and tightening, if necessary

Periodic maintenance

To ensure the life of your wind mill, we recommend the following maintenance steps:

Every six months and during season changes, the inspection of the following points is recommended

Checking and readjusting the torque required for every bolt

Checking cables state

Visual inspection of the blades

Checking that the automatic breaking system works properly by inclining it manually

All the main parts to revise on a wind turbine

Bearings

USCET wind turbines are equipped with great quality sealed bearings which requires no maintenance

Bolts

The bolts used in USCET wind mills are High tensile Galvanized steel or stainless steel. If a bolt is missing or in poor condition, it must be replaced right away in order to avoid any breaking or further damage.

Wiring

All cable connectors and switches must be properly checked in order to prevent any disconnection and to allow the wind turbine to run freely

Blades

The fiber glass re-enforce blades wear a protection made out of abrasive polyurethane paint of the blades. After years of use, this paint many be affected by the weather conditions.

Lubrication

 

 

 

 

THE USCET WIND TURBINE, HAVE 3 MAIN MOVING PARTS:

The front shaft (blades-Alternator) is equipped with sealed bearings and covered with lubricant. It does not need any special attention; its lubricant will last during its lifetime.

The Yawing shaft (windmill-tower) is equipped with sealed bearings and covered with lubricant. It does not need any special attention, its lubricant with last during its lifetime

Annex – III

Landscape and objects that influence on wind mills

When the wind is eclipsed by the objects it finds in its way, it reduces its speed and results in turbulences. A wind mill installed on the wrong place will not perform as it would in a non- influenced place.

To maximize the performance of your wind turbine, it should be installed the farthest away possible from the obstacle and over a tower higher of this obstacle.

If the wind mill is going to be installed in a valley, it should be done on the top where it will catch the wind from any direction or on the bottom where the wind is canalized.
