This study presents a realization process of a hybrid system consisting of biomass and wind as well as solar power generation on the ground of Ashikaga Intitute of Technology located in Ashikaga City of Tochiki Prefecture. The installation principle and procedure are introduced based on the conditions of natural energy such as wind speed and solar rediation degree. The output characteristics from 20 kW biomass generator is explained and analyzed in according to cooperational possibility with the wind power and solar power system. The operation characteristics of 40 kW wind power turbine is provided based on the practical operation data collected within three years and the simulated results obtained from the software calculation. The operation conditions of 20.6kW solar power system is also anaylzed based on the solar irrediance desity in the located site. The general efficiency of this triple hybrid power system in ecomomic and environment aspects is also studied by using and comparing the simulation methodology and the data in practical operation.
