Analysis of Power Quality in Jeju Power Grid with STATCOM
Abstract
This thesis presents the modeling and power quality analysis of Jeju power grid with STATCOM. In the study, five kinds of major components are modeled : a total of 172MW wind farms, 250MW HVDC system, thermal power plants, STATCOMs and Jeju power loads. To analyze the impact of the wind penetration to the Jeju power system, simulations are carried out for case studies by using PSCAD/EMTDC progam. One is for the steady-state operation under variable speed, and the other is for transient-state operation when one of wind farms or power plants are disconnected from the Jeju power grid due to sudden problems.
These comparative studies have been effective in studies for Jeju Island power system stability with STATCOMs.
