dc.description.abstractAs the number of installed wind turbines in the power system increases, it becomes increasingly necessary to ensure the wind turbines can meet the requirement of low-voltage ride-through (LVRT). Currently, there are several techniques to help the wind turbines to recover from the low voltage situation, such as SVC, STATCOM and crowbar circuit. In this project, SVC and STATCOM will be examined. The meaning of standard voltage-duration profile usually used as a guide in LVRT study is carefully examined firstly. The doubly fed induction generator (DFIG) model often used to represent wind turbine generator is developed to test the LVRT performance under various disturbance situations. Specifically six fault types are used to observe the voltage change. The impact of the faults on the LVRT ability is compared. SVC and STATCOM are incorporated in the system to investigate how they can assist the turbines to meet with the LVRT requirements. From standard voltage-duration ride-through curve, a LVRT criteria profile is built. In this way and for a given fault disturbance, from the simulation results of the wind turbine tenninal bus voltage and active energy, they are then compared with the developed LVRT criteria profile to show how the SVC or STATCOM has enhanced the LVRT capability.en_US
