1. FUTURE ON POWER
ELECTRONICS FOR WIND
TURBINE SYSTEMS

2. INTRODUCTION
•Wind turbine technology is the most promising
renewable energy technology.
•Started in 1980s with a 4-8 KW production of power
per unit.
•Today 4.5-8 MW production of power per unit.
•Initially no need of power control system to regulate
frequency and voltage.
•But now control system parameters are necessary part
of wind turbine systems.

3. DEVELOPMENT OF WIND POWER
GENERATION

4. ROLE OF POWER ELECTRONICS

5. WIND POWER CAN BE GENERATED BY-
 Doubly fed induction generator
 Synchronous generator

6. DOUBLY-FED INDUCTION GENERATOR

7. ADVANTAGES
•Low cost of converter
•Optimum utilization of
energy

8. DISADVANTAGES
•Slip rings
•Direct connection to the grid is
difficult
•The output voltage is dependent
on the rotor speed.

9. SYNCHRONOUS GENERATOR

10. ADVATAGES
• Elimination of slip rings.
• Full power

11. DISADVANTAGES
•Expensive electronic components.
•Higher power loss

12. TECHNOLOGY CHALLENGES FOR
POWER ELECTRONICS IN WIND
TURBINE SYSTEMS
•Lower level cost of
energy
•Stability
•Higher reliability

13. FUTURE TECHNOLOGY FOR WIND
POWER CONVERSION
• Generator and drive train
• Power electronics and
transformer
• Power semiconductor device

14. CONCLUSION
•Last four decades, wind energy is most promising
renewable energy
•Wind power reduces cost of electric energy.
•Use of power electronics system, it may be
conventional energy one day.
•Lower energy cost, higher reliability and better
power integration will push the technology in
developments in wind turbine systems.
