117 Power Quality Improvement in Windmill System Using STATCOM
Download citation file:
Wind turbine installation is increasing rapidly. Especially, the behavior of wind turbines during a power system disturbance would affect power system stability and supply security. STATCOM unit is developed to inject reactive power to mitigate power quality problems and to get stable grid operation. Due to continuously varying wind speed components, the active and reactive power along with terminal voltage fluctuates continuously. By connecting STATCOM into the grid, the active power, reactive power and terminal voltage is maintained constant . The STATCOM as a pure static device with no switched passive components provides outstanding performance for both steady state and dynamic operation.
