Tokyo, Japan, 10 February, 2011

Wind Power is Changing the World 194 GW of 200,000 wind turbines are working all over the world. 2% of World Electricity are supplied by “Wind Turbines”. 5% of World Power Generation Capacity are “Wind Turbines”. More than 10% of World New Power Plants are “Wind Turbines”.

Global Wind Statistics 2010, GWEC

Wind Power Generation in Japan Latest wind Power Statistics in Japan (at the end of 2010) - Total installed wind generation 2,304MW, 1,742 units - New wind generation installed 221 MW / year - Total electric output from wind 3,936 GWh / year - Wind generation share of national electric demand 0.4 %

Impact for WTG

Improvement a

・ Typhoon

→ Heavy Load by Wind → Tough Design

・ Lightning

→ Blade Destruction

→ Lightning Protection

・ Complex Terrain

→ High Turbulence

→ Fatigue Strength

･ Low Wind Speed

→ Drive with Low Wind → Low Wind Speed Model

･ Mountain Region

→ Difficult to Transport → Proper Blade Size

･ Not Strong Grid

→ Fluctuation Control

→ Combination with Battery

WTG Failures by Typhoon No.14 Maemi in Sep.2003 at Miyako Island

Reliable Blade Design

EdgeEdge-wise strength test

Flap Flap--wise static load strength test Flap Flap--wise fatigue load strength test

Flap Flap--wise strength test

WTG Failures Caused by Lightning “Winter Lightning” : Very very Strong Thunderbolts. Only happens on the coast side of “Japan Sea” in winter. Their Energy often exceeds IEC61400-24 Protection Level I specification.

Lightning Protection R&D Based on field measured data

Lightning Currents Detector

Verified by artificial lightning tests
