چکیده
To integrate the high penetration of power from wind farms into a grid, one key requirements posed by new grid codes is Low Voltage Ride Through (LVRT) capability. This paper studies voltage compensation-based methods to improve fault ride-through capability grid-connected Doubly Fed Induction Generator (DFIG). Bridge Type Fault Current Limiter (BTFCL) and Reactive Power Control (RPC), which acting as an active compensator, are cooperatively controlled in this study achieve better LVRT DFIG. Additionally, design considerations select shunt impedance BTFCL described get optimal performance system under consideration. The test was modelled simulated MATLAB/SIMULINK environment. effectiveness proposed method tested comparing it with conventional Crowbar resistance method. Simulation results show that cooperative control self-acting intelligent RPC can effectively reduce current, improves stator DFIG for continuous operation provides reactive support during conditions.

Review of Control Strategies for Dfig Wind Turbine to Enhance Lvrt Capability
Wind energy is the fastest growing renewable energy source. Double Fed Induction Generator, which is predominantly used nowadays in wind turbines, is very sensitive to grid disturbances and can damage the power electronic converters due to over voltage and over current. Therefore, protection elements which disconnect the machine during fault are very essential. But, in such cases, the reliabili...

متن کاملGA-Based Optimal LQR Controller to Improve LVRT Capability of DFIG Wind Turbines
Nowadays, the Doubly-Fed Induction Generators (DFIGs) based Wind Turbines (WTs) are the dominant types of WTs connected to grid. Traditionally the back-to-back converters are used to control the DFIGs. In this paper, an Indirect Matrix Converter (IMC) is proposed to control the generator. Compared with back-to-back converters, IMCs have numerous advantages such as: higher level of robustness, r...
