Comprehensive study on fault-ride through and voltage support by wind power generation in AC and DC transmission systems

Description

This paper exploits the impact of different Low Voltage Ridethrough (LVRT) methods and equipment on both the wind energy elements and the grid including wind turbine/farm ability to provide reactive compensation, and maintain controllability during faults. The potential of using SFCL as an alternative LVRT equipment is preliminary studied. The paper also exploits some severe scenarios that could face a multi-terminal HVDC network. The influences of AC faults and control errors are examined. Results show limited deviations between the adopted LVRT methods. The wind turbine has to contribute to the stability of the AC collection grid of the wind farm, but it does not influence the grid, as both are decoupled through the multi-terminal HVDC grid. The implemented test systems and the examined events are developed in Matlab/Simulink and DIgSILENT.
