A Grid Voltage Measurement Method for Wind Power Systems during Grid Fault Conditions

Autor: Cheol-Hee Yoo, Il-Yop Chung, Hyun-Jae Yoo, Sung-Soo Hong

Publikováno v: Energies, Vol 7, Iss 11, Pp 7732-7745 (2014)

Grid codes in many countries require low-voltage ride-through (LVRT) capability to maintain power system stability and reliability during grid fault conditions. To meet the LVRT requirement, wind power systems must stay connected to the grid and also

Deconvolution of site effects in ground-motion using site response function derived from HVSR method

Autor: Byeong Seok Ahn, Tae-Seob Kang, Hyun Jae Yoo

Site effects caused by unconsolidated sediments laying on the bedrock amplify or attenuate ground motions propagated to the surface. Site effect is unique site-by-site, and thus, makes analyzing actual attenuation characteristics of ground motions di

Teleseismic Rayleigh-wave phase velocity tomography in the southern Korean Peninsula

Autor: Joa Kwon, Hyun Jae Yoo, Tae-Seob Kang, Seongryong Kim, Sang-Jun Lee, Junkee Rhie

Surface wave dispersion is one of the essential means to study the structure of Earth’s crust and upper mantle. However, complicated structures of the Earth’s surface cause multipathing effects that make accurate phase measurement difficult. In t
