HYBRID POWER GENERATION SYSTEM OF SOLAR ENERGY GENERATION AND WIND POWER GENERATION

摘要

PPROBLEM TO BE SOLVED: To solve the problem that: in a conventional hybrid power generation system, (1) the rate of the utilization of the system cannot be sufficiently improved while surplus power is apparently utilized effectively by the use of a capacitor, but there has been some case that charged power has not been fully utilized because chargeable conditions are not easily satisfied, and (2) wind power generation has not been brought into successful utilization because there has not been provided a charging means adapted to the frequent rise and fall of power that is one of characteristics of the power generation efficiency of the wind power generation. PSOLUTION: Parallel generation is made possible by arranging a boosting and step-down machine improved in controllability at the output side of the wind power generation. The surplus power and power not satisfying a DC-AC converter input specification are accumulated by employing the capacitor, the generation output of the system is discharged when the output is less than a sales contract power value, and the efficiency of the system is improved as a whole. The system is made to be the one for constant monitor and control by arranging a control device for controlling a large number of apparatuses. Furthermore, an electric double-layer capacitor is employed in addition to a normal battery as a member of the capacitor, thus improving a storage property. PCOPYRIGHT: (C)2005,JPO&NCIPI
