Abstract
StatCom is a type of device that can be used for controlling as well as reducing positive and negative sequence voltages produced in a system. It is a static synchronous generator which controls capacitive or inductive output current irrespective of the ac system voltage. The main source of arising of positive and negative sequence voltages are generation of unsymmetrical faults in a wind farm. Positive sequence voltage causes voltage instability and negative sequence voltage causes heavy generator torque oscillations which leads to mechanical vibration. Unbalanced voltage causes unbalanced heating in the machine winding.Therefore at first, current capability of StatCom can be controlled for removing positive sequence voltages for improving voltage stability and then remaining current is controlled for eliminating negative sequence voltages.
Keywords
