The Extension of an Application Shell For Turbine-Generator Diagnosis

As a variety of techniques and problem-solving methods become available for expert systems, practitioners need to understand how specific domain and task characteristics should influence the selection of methods. The diagnostic task domain varies with respect to many attributes. These include the amount and quality of data, degree of access to component failures, conclusiveness of test results,...

Dynamic performance improvement of an isolated wind turbine induction generator

A dynamic model of a variable speed stand alone wind generation unit is developed. The steady state as well as the dynamic performance of the wind system is explored. The necessary conditions for steady operation have been established. The performance of the system under variable wind gust and other disturbance conditions has been studied. It has been observed that a stand alone generator is ve...

Micro-siting technique for wind turbine generator by using large-eddy simulation

It is highly important in Japan to choose a good site for wind turbine generators, because the spatial distribution of wind speed is quite complicated over steep complex terrain. We are developing the unsteady numerical model called the RIAM-COMPACT (Research Institute for Applied Mechanics, Kyushu University, Computational Prediction of Airflow over Complex Terrain). The RIAM-COMPACT is based ...

Micro Electret Power Generator

We present the first micromachined rotational electret power generator, linearized theoretical model of electret power generation, and novel method to produce uniformly charged electret. We also improved our previously developed [ I , 21 thin film Teflon AF 1601-S electret technology with respect to dielectric thickness, charge uniformity, and processability. In demonstration, our prototype pow...
