  • Abstract When the wind power accounted for a total generating capacity reaches a certain percentage, wind turbine's ability to maintain operation during a fault will affect the overall balance of power system generation and electricity. Enhanced Low Voltage Ride Through (LVRT) measures can improve the stability of wind power generators and system. This study investigates the capability of two LVRT enhancement methods, i.e. the use of bypass circuits to stabilize the DC bus voltage, and a shunt Static Var Compensation (SVC) to raise terminal voltage and output power, in a simple network.
    Digsilent PowerFactory software is used in this study to create two wind generator models, Doubly-Fed Induction Generator (DFIG) and Permanent Magnet Synchronous Generator (PMSG) models. Transient responses during system faults with and without LVRT enhancement are compared. Simulation results show that the application of LVRT enhancement helps improve the wind turbine stability and the effectiveness of the control measures is different for different types of wind generators.
