Main results after regular operation of the HVSMPS for gyrotrons
A new high voltage power supply for gyrotrons using solid-state elements was developed by JEMA. In 1992, this power supply was put into operation on gyrotrons at CIEMAT. In this paper, the parameters of the power supply and its behaviour in the regular operation of the TJ-II stellarator are presented.
This study investigates the effects of Pierson-Moskowitz, Jonswap spectrum that are typical irregular wave spectrums for wind turbine system with jacket support structure. Also various offshore environmental parameters based on korean local condition were used in our study. The loads acting on the system was considered by referring to the Design Load Case from IEC guide line. And improved von Karman model was used as a turbulence model. As a result, various significant wave height and peak spectral period cause noticeable difference of extreme and fatigue loads prediction.
