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 کاملControl and Simulation of a Crowbar Protection for DFIG Wind Turbine during Power Systems Disturbance
The use of the doubly fed induction generator (DFIG) in modern variable-speed wind turbines has increased rapidly. According to the new grid code requirements, wind turbines generators must remainconnected to the grid during grid disturbances so crowbar protections systems is being used to protect the DFIG, this paper introduces a comparison between conventional crowbar protection, series crowb...
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 type 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, re...

متن کاملCoordinated Control Strategy for a Hybrid Wind Farm with DFIG and PMSG under Symmetrical Grid Faults
This paper presents a coordinated control strategy for a hybrid wind farm with doubly-fed induction generator (DFIG)and direct-driven permanent-magnet synchronous generator (PMSG)-based wind turbines under symmetrical grid faults. The proposed low-voltage ride-through (LVRT) strategy is based on a novel current allocation principle and is implemented for individual DFIGor PMSG-based wind turbin...
