2. wind turbine
 WIND TURBINE :- A wind turbine is a device that
converts the wind’s kinetic energy into electrical
power.
 TYPES OF WIND TURBINE.
 1)Horizontal wind turbine: , the axis of blade
rotation is parallel to the wind flow.
 2)Vertical wind turbine: Although vertical axis wind
turbines have existed for centuries, they are not as
common as their horizontal counterparts.

5. LIGHTNING
 Lightning is a sudden electrostatic discharge that
occurs during an electrical storm.
 Effects of lightning.
 1)Direct effects
 2)Indirect effects

6. METHODS FOR WIND TYRBINE
LIGHTNING PROTECTION

8. METHODS FOR WIND TURBINE
LIGHTNING PROTECION
 Receptor attachment: The placement of receptors
on structures, such as wind turbine blades, is
performed using statistical models. A risk
management approach is required to determine
the receptor number and placement to provide
optimum protection.
 The design of the receptor itself also influences
its ability to capture the lightning.

LIGHTNING PROTECION

10. METHODS FOR WIND TURBINE
LIGHTNING PROTECION
 Critical elements of blade lightning system
Conductor Technology :
 the conductors must maintain the following
characteristics:
 1) Low inductance per unit length.
 2) Low surge impedance Current-carrying capability
to withstand, without degradation, the thermal and
mechanical effects of lightning.
 3) Resistance to environmental effects.

11. ADVANTAGES
 Renewable energy
 Pollution free
 Cost effective
 Does not use water
 No fuel charges

12. DISADVANTAGES
 Causes death to wildlife, such as birds and bats
 Wind turbine cannot build anywhere
 Generate noise, some people does not like
 Wind is not always predictable

13. CONCLUSION
Wind turbine blade is one of the most vulnerable
parts of the damage of lightning. On the basis of a large
number of research data, this report analyzes the
mechanism of the damage caused by lightning strike,
sums up several lightning protection measures of the
blades of the wind turbine and introduces one invention
patent. At the same time, the author introduces a
simulated experiment about the blade struck by lightning
in Japan. It shows that the installation of lightning
arrester can effectively intercept lightning in the blade
tip. Also, if the lightning arrester is roughly the shape of a
disk which installed on the surface of the blade, it will
engender electric arc inside.
