Eigenvector Centrality Measurement Using Patent Information of Wind Power Energy

Abstract:

Wind power generator produces electric energy using wind. Since fuel for operating a wind power generator costs almost nothing, it is receiving attention as a power generator for the next generation. A wind power generator consists of a device that absorbs and converts the energy of wind power, power train, and control device. Each element is connected as a whole while it performs its function. In this study, we used the patent IPC information related to segmented technologies of this wind power generator to establish a two-mode network, measure eigenvector centrality value and identify the field with the highest influence among the fields of wind power energy. In the result, the field of generator was found to have the highest influence, followed by operation system and blade. It was analyzed that the field of generator had the highest influence since H02K and H02P, the IPC codes in the field, were the important technologies that influenced on other fields. In addition, H02N and H02N, which are main IPC codes in the field of solar cell, were analyzed to have connection with the field of generator.
