This DC current is fed into the inverter(s) (item F), which converts it to the AC grid voltage and frequency. The inverters also act as wind turbine controllers, constantly monitoring turbine speed and adjusting the amount of power that they take from the turbine to let the turbine run at its most efficient speed. From the inverters the AC current is connected via the energy meter (item G) and fuse box (item H) to the wind system/mains Isolator (item I). The energy meter records system energy produced and the energy consumed in keeping the inverters turned on if there is insufficient wind to produce power from the turbine. The turbine is designed to automatically control its speed and power generation without the need for manual intervention. In the case of a grid failure, or if the grid is turned off by the distribution network operator to allow maintenance, the inverters will automatically disconnect the turbine from the grid and refuse to take power from the turbine.


3. Starting up and shutting down your system There may be occasions when owners may wish to stop the turbine or to isolate it from the grid connection when, for example, electrical work is being carried out on the house wiring. The levels of shutdown which can be employed are as follows.

(A) Isolate the wind turbine from the grid

• Switch the wind system/mains isolator (item I) to ‘OFF’ This will leave the turbine running, but will provide complete electrical isolation of the wind turbine system from the distribution board to which it is connected. Note: that the electrical panel shown in figure 1 will still be live, as it is still connected to the wind turbine. The supply from the turbine to the electrical panel can also be isolated using the isolator switch mounted in the rectifier box (item J). NOTE: The wind turbine isolator on the rectifier box (item J), should never be switched from ‘OFF’ to ‘ON’ when the turbine is turning as this leads to a sudden inrush of current which can damage an inverter. Always stop the wind turbine before turning this isolator (item J) back to ‘ON’.

(B) Stop the wind turbine

First locate the turbine switch box. This will normally be housed inside the tower base. A small, 3-way brake control toggle switch is mounted in the side of the box. On top of the box is a label giving the function of the 3 positions (figure 3.1). When the turbine is running, the switch is in the ‘RUN’ position. When the switch is in the central ‘STOP REQUEST’ position, the rotational speed at which the brake will be applied is reduced so that the protection circuit will trigger in normal wind speeds above about 5 metres/second (11 mph). Therefore, this switch position can be used to demonstrate that the protection system is functioning correctly.

(C) Enforcing a turbine shutdown

Move the 3-way brake control switch across to the ‘HOLD FOR STOP/START’ position and hold it there for 2-3 seconds until a whistle can be heard at the top of the tower or the rotor stops turning. Immediately release the switch. This operation will apply the brake and the turbine will stop.

(D) Start the wind turbine

To start the turbine up again move the 3-way brake control switch back to the ‘HOLD FOR STOP/START’ position and hold for about 2-3 seconds, or until you hear the whistle, then immediately release the switch, this releases the brake.

Note: That in light winds the turbine may take some time to start moving.

When the brake has released, move the 3-way brake control switch to the ‘RUN’ position. If the switch is left at the central ‘STOP REQUEST’ position the turbine will automatically stop itself when it reaches around 160 rpm.

Tip: The protection system obtains its power from the wind turbine itself and does not rely on batteries to function. However, whenever you enforce a stop (using ‘HOLD FOR STOP/START’), or release the brake to allow the wind turbine to start, the circuit uses power from 2 x 9V batteries (PP3) that are located within the turbine switch box. Tip: Power is drawn from these batteries only when you move the switch to the ‘HOLD FOR STOP/START’ position so they should last for several years. The service teams will check the batteries and exchange them as part of the annual inspection.


4. Inverter status The Inverter/s is located on the electrical equipment panel (figure 1 item F) Three coloured LED’s are provided on each inverter panel (figure 4.1) to indicate its status. There is also an LCD display which shows details of turbine output and inverter status. If the inverter is showing a single red light, this indicates that it has switched off. This is usually due to the grid supply either being switched off, or its voltage or frequency having moved outside of the allowable limits. The inverter LCD display should be displaying an error code which will describe the problem. (See the SMA Inverter Operator Manual supplied with your system for details of error codes).

Table 1: What to expect to see on the inverter and electrical meters

Wind condition Approximate speed of wind turbine

Expected state of the lights on the inverters

Still Turbine stationary or rotating at less than 50 rpm

After one hour of very low wind speed, or a still wind, the inverters will switch themselves off. All lights will go out.

Light winds that are sufficient to turn the wind turbine only slowly

Turbine rotating at 50 - 100 rpm

The inverters will begin to come to life once the turbine reaches around 60 rpm. All three lights will come on, faintly at first then more brightly as the turbine gains speed.

Winds above 3 m/s

Turbine rotating at 120 rpm or more

As the turbine speed increases the inverters will begin an initialization period. During this the green light will start flashing and other lights will go off. The inverters are waiting for the right wind and grid conditions to be able to deliver power. When the inverter has synchronised with the grid and the reconnection time has elapsed the inverters will come on-line. The green light will stop flashing and become constantly on.

All other normal wind conditions

The turbine will vary speed according to the available wind. In strong winds the turbine will control its speed by varying the blade pitch. There is a distinct change in the aerodynamic sound of the wind turbine when this occurs.

The green light will be constantly on.

5. Reading the meter The Energy meter (item G) gives the output in kWh of your turbine since commissioning. The meter display periodically flips between a large number, which is the output of the turbine, and a much smaller number which is the energy absorbed from the grid by the inverters when the turbine is not running. There is also a red light on the meter that flashes at a frequency which increases as more power is generated by the turbine.

6. Maintenance Maintenance of the Evance R9000 wind turbine is designed to be straightforward. In order for the warranty to be valid, maintenance should always be carried out by installation and maintenance teams who have been specifically trained and accredited by Evance. Please contact the company that installed the turbine to find an accredited maintenance team. The R9000 turbine should have its scheduled maintenance check performed by an accredited maintenance team. The R9000 is a reliable machine and so should not need any additional maintenance. However, if problems do arise, early recognition by the owner can save costly repairs. To be able to recognise unusual behaviour in your R9000, you should first know what normal behaviour looks like and sounds like, so try to observe and listen to your turbine in all wind conditions. Do this upwind and downwind of the machine and also look at the behaviour of the lights on the inverter/s (see Section 4 table 1). We recommend a visual and listening inspection of the turbine every couple of months.

Inspection

1. If the wind is blowing, is the rotor rotating at a speed you think looks right for the wind conditions?

2. If the wind is blowing reasonably well, is the turbine pointed into the wind?

3. For the wind conditions, are the lights on the inverter/s as they should be?

(See table 1).

4. Listen for unusual noises, e.g. regular noises that seem to be related to the speed of the rotor.

5. Check the tower base for loose fasteners or any unusual noises or movements.


Be careful not to confuse turbine noises with background noises on windy days. In very light winds at low rotational speeds there is often a once per revolution tapping sound from the machine. This is quite normal and is due to the blades settling under the force of gravity, with the force on each blade reversing as it goes over top dead centre and bottom dead centre positions. If however there are any unusual or loud noises which could potentially indicate a problem, the Evance installer who supplied the machine should be contacted immediately.

7. What to do if there is a problem Warranty and maintenance questions should be directed to your local reseller or installer. If you have any concerns about the operation of your wind turbine, please contact them with:

1. Accurate description of the symptoms.

2. Wind conditions when symptoms occur.

3. How long the symptoms have been occurring.

4. If the symptoms have become worse. Your reseller or installer can advise if a problem is potentially serious, or if it can be left until the next maintenance visit.
