英文要約 For development of Gyro-type CPV (concentrated photo voltaic), the central target of the development is “ weight-lighting / self-powering and self-controlling/ wind resistant reinforcement / high performance- and low price-mirror “. To reduce the weight of the mirror board which carry the mirrors, we have achieved to develop the new type of mirror made of the resign mirror with Fresnel reflective structure. Moreover, the mirror reflectivity and mirror corrosion resistance have been studied for the resin mirror. For the fabrication of the Test Machine II, the mirrors were not fixed to the body due to the mirror development for a higher reflectivity and corrosion resistance. One set of the solar concentration component was fixed to one of the nine Test Machine II in order to develop the solar concentration component in the next FY. An optical measurement system for the high flux distribution of the concentrate solar beam was prepared for the development of the solar concentration component. The Gyro-heliostat concept is that the mirror plane weight is always balanced in any configuration during the sun-tracking. This results in the small electric power consumption due to the small torque of the motor movement to change the mirror configuration during the sun tracking (Gyro-drive). For the Test Machine I, the Gyro-drive with motor was fabricated with the specially designed pulley. This pulley mechanism is slightly lower for the strong wind power, therefor we have changed the pulley mechanism to the actuator mechanism which is high resistance for the strong wind. The wind resistant reinforcement is high and significantly durable for the wind velocity of 50m/s. For the Gyro-drive quality test, we have measured the weight balance quality and the electric power consumption level. The weight balance was completely maintained even under the load of 100kg. The electric power consumption for actuator drive was 10W/min (0.17W/s), which is quite low compared to the power consumed for the conventional heliostat. This small power consumption is very useful for the development of the self-powering heliostat. We have installed the self-power generator using another PV power generation system (Self Powering Source) for the test of the self-powering of the Gyro-type heliostat in the next FY. Also, we have settled the power consumption measurement system for the Self Powering Source performance and for making clear the small electric power consumption by the Gyro-drive mechanism.
