17 3 Tower Installation

3.1 Siting

An ideal location for wind generator is required with stable speed and direction of prevailing wind. Small changes in wind speed and direction can
have a dramatic effect on power production. In general, the higher the tower, the greater the wind speed and ultimately power productio n are.
Therefore, the site of your wind turbine should be carefully considered. Each installation is different and is often compromi sed among the tower
height, distance from the battery bank, local zoning requirements and obstacles such as buildings and tr ees. Following requirements should be
followed:

• The minimum recommended tower height is 2 0 ft (6 m) on open ground or 20 ft (6 m) above nearby obstructions (refer to following figure ).

• Try to locate the wind turbine in the “cleanest” turbulent fre e air as possible. Turbulence will reduce the efficiency of wind turbine and may
accelerate wear on rotating components.

• Try to locate the turbine without obstacles within 200m of installation center.

18
• The installation d istance between two turbines sh ould be 8 -10 times of the rotor diameter.

• Installation site should be complied with local regulation s.

Safety must be the primary concern when selecting the mounting location. Even if installing the wind turbine in a less ideal location, don’t attempt to
mount the turbine while blades are spinning. Safety has precedence over efficiency.

WARNING: Even if install ing the turbine in a less windy location , the three -phase wires must be short circuit ed during installation to prevent the
turbine from turning.

3.2 Design Requirement s

The tower has a direct effect on the safety of the wind turbine . HYE offers some tower choices for HY series wind turbine . The following section
provides a summary of the available towers.

20 Special installation 2: flat roof top

Explanations :
1.This installation is workable for flat roof top.
2.The wall or gr ound of rooftop should be concrete or
solid wall.
3.The installation s could be both used expansion bolt
to fix the supporting structure.
Dimension requirement:
① Distance from rotor centr e to roof top ≥ 6 m
② Supporting point should be 1. 0 times of t he
rotor diameter
③ Distance from blade tip to pole ≥ 250 mm
④ Φ114mm≤Outer diameter ≤Φ150 mm
⑤ Angle steel or guyed fastening structure

21 4. Wire Size Selection
All electrical systems lose energy due to resistance in conductors: the wires.
• The larger the wire is , the l ess resistance and the loss are
• Resistance losses will also increase with increasing current; therefore, if you installation is at a high wind site, it may be worthwhile to go with a
larger size wire to lower the loss and enhance the output of wind turbine.
• Conversely, in low wind sites it may not be cost effective to increase the wire size since power production will be comparative lower.
To determine the wire size, measuring the d istan ce from the batteries to wind turbine is necessary, b e sure to include height of the tower. Refer to the
appropriate chart for your system voltage and select the wire size. The following wire sizes provide maximum annual energy losses of 3% for most
sites.

22 5. Troubleshooting
5.1 W ind Turbine Troubleshooting

5.1.1 Wind Turbine Vibration
Wind turbine vibration is mainly caused by the following factor s:
1) The blades mounting bolts get loose and need to be tightened;
2) The surface of blades gets frozen and needs to be removed;
3) The blades have been distorted, defected and need to be replaced .
4) The tower is not strong enough or guy rope gets loose, and needs to be reinforced or tightened;
5) The wind turbine operates lacking phase, need to check if the three -phase output voltage is balanced or not by testing with multimeter .

IMPORTANT: Turbine operation should be stopped as soon as abnormal vibration happened till problems solved to avoid personnel or
machine damaged.

5.1.2 Wind Turbine Insensitive to Adjust Rotor Direction
1) HYE wind turbine mainly adopts tail yaw ing to adjust the blades direction, if it is not sensitive to adjust blades direction, reasons may be: the
turbine alternator shaft is damaged, or the tower is out of plumb.
2) The tower flange is not matching with the flange on turbine , which cause the interference to adjust the wind turbine facing direction . ① check
if the flange is provided by HYE or in accordance with HYE flange drawing; ② check if the flange on turbine is loose, and if the axis of
rotation fall in to the tower.
3) The wind turbine is in a swing ing or seeking stat us: ① the wind turbule nce caused by natural factors is normal; ② improperly located, if
turbulence is caused by building s, wind turbine should re -locate another good position.

23 5.1.3 Rot ation seed Dramatically Decreases
Wind turbine rotation speed dramatically decreases under heavy wind condition, which can be mainly divided into normal deceleration and
abnormal deceleration:
1) Turbine normal deceleration is due to wind turbine over -spee d protection, for example, dump load, electromagnetic braking and blades
aerodynamic braking. These are regular protection ways to protect the wind turbine and the whole system in high wind.
2) Turbine abnormal deceleration is mainly due to friction betwee n rotor and stator, bearing damaged, generator burned, blades deformation
or damaged, turbine or pole shake heavily, in case of these situations, please disconnect wind turbine from controller and put three -phase in
short circuit mode, then contact supplie r to solve the problem.

5.1.4 Generator Abnormal AC Output
1) Generator abnormal which is due to long connecti ng wire or small wire size which results in high pressure drop, therefore, selection of wire
size should refer to 6.5 regulations and requirement s.
2）Check if the wind turbine three -phras e output performs well , check the voltage of each two of the output phase s are balanced .
3) Generator three -phase output voltage is imbalanced. Voltage unbalanced rate shall not exceed 10% (same wind speed or r otational speed)
in accordance with related national standards, if exceeded, the generator fails, please contact supplier to solve the problem.
4) Generator has no output voltage under heavy wind condition, check whether generator is under short -circui t mode or not (reference: 5.2)
and three -phase resistance values is balanced or not (uncharged operation), if imbalanced, the generator fails, please contact supplier to solve
problems.
WARNING: Never c heck the wind turbine while the blades are spinning o r on a windy day.

5.1.5 Abnormal Noise
1) Friction between rotor and stator, or bearing damaged – please contact supplier to solve the problem.
2) Check if wind turbine is rotating abnormally, or noise generated by self -vibration.(reference:5.1.1)

24 5.2 System Troubleshooting

5.2.1 Off -grid wind and solar hybrid system

5.2.1.1 Solar Output Voltage Too Low or No Output
1) Check whether solar panel lead is short circuit, circuit break, open circuit or not.
2) Check whether solar panel is damaged or accumulated too much dust, etc.

5.2.1.2 Abnormal charging
Wind turbine does not charge battery is mainly caused by:
1) Wind speed is too low to reach cut in point . For the off -grid system, when the DC input voltage is higher than battery voltage, it s tarts to
charge the battery, otherwise it will be no charging.
2) Wind speed is high, but Wind Turbine Does Not Charge Battery
a. The wind turbine DC output voltage is lower than battery’s: ①check whether the output of wind turbine is normal (reference : 5.1.4);
②check whether the rot ation speed of wind turbine is normal.
b. The wind turbine DC output voltage is higher than battery’s: ① check whether the system wiring is correct and each terminal wiring is well
connected; ② check whether the controller could rectify power normally . (refer to controller user manual)
c. The type of battery and controller does not match, replace the battery ( lead-acid or AGM gel batter y is recommend ed);
d. The battery reached saturation, so wind turbine is on braking mode be cause of overcharge protection function of the controller

5.2.1.3 Abnormal output
1) Control mode of controller is set incorrectly or damaged and need a replacement. (Reference: controller user manual)
2) Battery is under over-discharge state, check th e battery voltage and need to exclude the reason of low battery voltage. (Reference:
5.2.1.2)

25 5.2.2 Grid-tied Wind Turbine System

5.2.2.1 No power feed into grid
1) wind speed is too low, wind turbine still haven ’t reach it ’s cut -in wind speed, so no current generated in less than 2.5m/s wind speed.
2) Wind speed is too high, wind turbine output voltage reach the over -voltage point, controller short -circuit braking system protect the wind
turbine and the whole system, the system will restore automa tically when the wind speed decrease.
3) The controller short -circuit brake was switched on manually, it will restore when switch on the short -circuit switch manually.
4) On -grid inverter is in disconnected from grid or damaged. (Reference: inverter user manual)
5) Check whether controller DC output voltage is normal. Troubleshooting: ①wind turbine troubleshooting (Reference:5.1.4); ② check whether
the controller is damaged (Reference: controller user manual).
6) Check whether the system wiring is correct, not e that electrodes should be connected in a right way, the system will restore by automatically
after reconnected.
7) The wind turbine output characteristics and inverter does not match; solutions: ① replace wind turbine; ② replace on-grid inverter; ③ adjust
the internal parameters (power curve and power factor setting )of the on-grid inverter.
8) Check whether the wiring is loose, poor contact and the state -grid is stable.

5.2.2.2 Low charging power
1) Wind turbine output voltage is low ; main reason s: ① low wind speed; ②wind turbine troubleshooting (Reference: 5.1.4).
2) The wind turbine output characteristics and inverter does not match; solutions: ① replace wind turbine; ②replace the on-grid inverter; ③ adjust
the internal parameter s of on -grid inverter.

26 6. Maintenance

27 Appendix I
Definition of 50m/s survival wind speed of HYE wind turbine
HYE wind turbine is strict in accordance with following standards:
GB/T 10760.1 Generator of Off -grid Wind Tur bine Generator System Part 1:Technology condition
GB/T 13981 -2009 Design General Requirements for Small Wind Turbine Generator System
GB 17646 Safety of Small Wind Turbine Generator System
GB/T 19068.1 Off-grid Wind turbine Generator Systems Part 1:Techno logy condition
JB/T 10399 -2004 Rotor Blades for Off-grid Wind Turbine Generator System
JB/T 10402.1 -2004 Yaw System of Wind turbine Generator Systems Part 1:Technology condition
JB/T 10403 -2004 Tower for Off-grid Wind Turbine Generator System
JB/T 10405 ―2004 Technical Condition for Foundation and Linkage of Off -grid Wind Turbine Generator System
NY/T 1137 -2006 Installation Specification of Small Wind Turbine Generator System

Our HYE wind turbine belongs to Class III in accordance with wind turbine i nternational grade, please refer to following chart,

In order to be compatible with extreme load of international safety standard, while calculation of the load, the
and all of wind speed which is
calculated by
should be reduced by 7% .
As we all know, the huge wind, storm or hurricane usually does not last for a long time, assuming a huge wind occurred once i n 50 years, the average
maximum wind speed within 5 seconds at hub height is represented by
, it is calculated by
multiply coefficient 1.4, that is
=1.4

28 From above explanation, the survival wind speed of Class III wind turbine is:

=1.4
-1.4
*7%=1.4*37.5 -1.4*37.5*7%=52.5 -3.68=48.82m/s ( ＜50m/s)

So this is why the survival wind speed of HYE wind tu rbine is 50m/s.

Generally speaking, the safety and operation of wind turbine is closely related with matching components, correct pole instal lation, correct system cable
connection, these three factors we could control and we have to do them well, Howeve r, wind turbines are installed outdoors, it is also close with natural
environment situations, in case of force majeure factors, such as storm, earthquake, or attacked by hailstone, dust, wind tur bines may be damaged .
