Fractional-slot windings is widely used in synchronous machine due to give us more flexibility on selection of the number of slot at design stage. It is also known that fractional-slot windings produces additional harmonics compare to integral-slot windings. These harmonics may cause increasing of stray losses and stator core vibration This paper describes the result of space flux harmonics caused...
It is known that space flux harmonics generated by fractional-slot winding are different from ones generated by integral-slot winding. The authors reviewed space flux harmonics caused by fractional-slot winding and developed a new winding method, which is based on intersperse one coil winding, to reduced low order space flux harmonics components. The validation for the new design has been also completed...
This paper presents the characteristics of equivalent circuit model for large synchronous machine and its implementation by using finite element method (FEM) and electromagnetic transients program (ATP-EMTP). Reactance saturation influence of large turbine generator is also explained in this paper.
R&D of the performance measurement technologies for CPV (concentrating photovoltaic) devices at National Institute of Advanced Industrial Science and Technology (AIST) have started in FY2009. Indoor characterization technologies for CPV mini-modules (CPV cells with concentrating optics) have been developed using a highly parallel continuous solar simulator (HPCSS), which has a highly-parallel...
