  1. THE FIRST RENEWABLE ENERGY TRIPLE HYBRID GENERATION SYSTEM IN THE WORLD Yasuyuki NEMOTO (Ashikaga Inst. of Tech.) Yoshifumi NISHIZAWA (Ashikaga Inst. of Tech.) Izumi USHIYAMA (Ashikaga Inst. of Tech.)

  2. Introduction Because of the need to prevent problems such as global warming, The importance of renewable energy with low impact on the environment has been increasing in recent years. However, the actual introduction of these systems has been hindered because the power source of renewable energy is unstable.

  3. Purpose In order to stabilize the power source, Wind and Solarenergy which depend on weather conditions Biomass energy which can be stored and its input regulated Triple hybrid renewable energy generation system Triple hybrid renewable energy generation system Triple hybrid renewable energy generation system A. I. T has carried out the demonstrative study of this system.

  4. Triple Hybrid Renewable Energy Generation System

  5. Overview of the system Biomass Generation System Wind Turbine Generator PV System

  6. Wind turbine generator (SUBARU 15/40) WTG System Specifications of the WTG

  7. PV module (HIT-190B2) PV System Specifications of the PV module

  8. Biomass Generation System Principle Biomass -> Gasification by partial combustion -> Flammable gas (main component = CO) -> Combined with air and sent to the IC engine -> Output from engine generator Characteristic - High efficiency - Compact system

  19. Manage to Vibration and Noise Problems WTG Remodel the Generator

  20. Repair work for the Generator WTG

  21. Failure of the coupling by Excessive Torque Biomass G

  22. Effect of Unsuitable Combustion Biomass G Deformation of fuel Clinker (about 1200℃） Tar sticking (low temp.) Choking of Furnace (high temp.)

  23. Concluding Remarks • The proof examination of the triple hybrid generation system has gone smoothly, however some problems have occurred. • We are working on improvements or a re-design to solve these problems. • We are planning to construct a system that can supply electricity consistentlythroughout the year in the future.
