This paper analyzes the steady state characteristics for variable speed wind power system with doubly-fed induction generator(DFIG). This paper explains the equivalent circuit and phasor diagram of DFIG for different operating conditions. It also simulates the torque-slip characteristics with respect to changes of different parameters. Simulation results show the torque-slip characteristics, stator power factor-rotor voltage and stator current-rotor voltage.

It is essential to carry out site investigations such as SPT, CPT sampling etc. to understand the characteristics of soil deposits. However, the results deduced only from the engineering standpoint have limited information to fully understand ground characteristics. In this study, it is discussed site investigation results on Youngjong deposits obtained from not only the geotechnical standpoint, but also geotechnical and geological mixed standpoint to understand correct characteristics of Youngjong soil deposit.

Rubber has high damping and can be formed as various shape according to specific purpose. So, Rubber has widely used as isolation mounts. However, there are still a lot of difficulties in understanding of static and dynamic characteristics of compressed and shear rubber mounts. In this paper, Static characteristics of the rubber isolation mount are observed by the analytical method and FEM. Also dynamic characteristics of rubber mount under compression and shear strain are investigated.
