Improved Control Strategy for Low Voltage Ride Through Capability of DFIG with Grid Code Requirements
This paper deals with a protection and control strategy to enhance the low voltage ride through capability of a wind turbine driven doubly fed induction generator (DFIG). As the wind power penetration continues to increase, wind turbines are required to provide Low Voltage Ride-Through (LVRT) capability. Crowbars are commonly used to protect the power converters during voltage dips and their ma...
متن کاملLow Voltage Ride Through Enhancement Based on Improved Direct Power Control of DFIG under Unbalanced and Harmonically Distorted Grid Voltage
In the conventional structure of the wind turbines along with the doubly-fed induction generator (DFIG), the stator is directly connected to the power grid. Therefore, voltage changes in the grid result in severe transient conditions in the stator and rotor. In cases where the changes are severe, the generator will be disconnected from the grid and consequently the grid stability will be attenu...
متن کاملEfficient low-voltage ride-through nonlinear backstepping control strategy for PMSG-based wind turbine during the grid faults
This paper presents a new nonlinear backstepping controller for a direct-driven permanent magnet synchronous generator-based wind turbine, which is connected to the power system via back-to-back converters. The proposed controller deals with maximum power point tracking (MPPT) in normal condition and enhances the low-voltage ride-through (LVRT) capability in fault conditions. In this method, to...
متن کاملLow voltage ride-through capability improvement of DFIG-based wind turbines under unbalanced voltage dips
This paper proposes a competent and effective scheme to enhance the ride-through capability of DFIGbased wind turbines under unbalanced voltage dip conditions. The proposed method is realized through joint use of the rotor-side converter control and a three-phase stator damping resistor (SDR) placed in series with the stator windings. By means of an asymmetrical SDR idea, during the unbalanced ...
متن کاملLow Voltage Ride through Capability Improvement of Dfig Based Wind Turbine Using Statcom
This paper studies a control strategy to improve low voltage ride through (LVRT) capability of doubly fed induction generator (DFIG)-based wind turbine (WT). This solution is based on the DFIG with Crowbar circuit control and the installation of STATCOM which is connected at the point of common coupling (PCC). The simulation model of WTs with STATCOM is built using the environment MATLAB/Simuli...
