Development of Condition Monitoring System

Aiming at the prevention of global warming, energy conservation and the reduction of power generation cost, demonstration and full-scale production of power generation devices using renewable energy are well underway. In Japan, the feed-in tariff program for renewable energy (photovoltaic, wind, hydro, geothermal and biomass power) started in July 2012 and their deployment is expected to accelerate. Among these, the cost of wind power generation is low among renewable energies, and many sites are actually deployed as key power generation facilities in Europe, which is a leading region for wind power generation. It is expected that wind power generation will further expand as larger wind power generation facilities are developed for off-shore deployment, and large-scale introduction in the Asian region is expected as well. NTN introduced the Condition Monitoring System (CMS) for wind power generation as a product for the renewable energy market that supports the nextgeneration power industry, taking advantage of vibration analysis technology and sensing technology. Through various improvements since its introduction, we now market this system as Wind Doctor ® as shown in Fig. 1. We are increasing the number of installations
