“…Blade pitch angle controller (BPAC) is the basic turbine controller used to enhance the LVRT capability also regulates the output power and protects the DFIG during wind turbulences. By adjusting the BPAC the power generated by DFIG can retain during bumpy wind speeds [29]. The stress on electrical and mechanical structures reduces and also maintains rated output in transient conditions.…”

“…During normal operation, when wind speed exceeds the threshold value, blade pitch angle controllers can modify the speed of rotor windings to maintain tip speed ratio. In this case, output power can be kept at the rated value, and the electrical and mechanical stress of wind turbines can be limited [61,62].…”

In recent years, considerable advances were made in wind power generation. The growing penetration of wind power makes it necessary for wind turbines to maintain continuous operation during voltage dips, which is stated as the low-voltage ride-through (LVRT) capability. Doubly fed induction generator (DFIG)-based wind turbines (DFIG-WTs), which are widely used in wind power generation, are sensitive to disturbances from the power grid. Therefore, several kinds of protection circuits and control methods are applied to DFIG-WTs for LVRT capability enhancement. This paper gives a comprehensive review and evaluation of the proposed LVRT solutions used in DFIG-WTs, including external retrofit methods and internal control techniques. In addition, future trends of LVRT solutions are also discussed in this paper.

“…Therefore, research on the fault detection of WECSs has practical significance. At present, the research objectives of WECSs are mainly focused on single components, such as a blade pitch [1][2] , doubly fed induction generator [3][4] , or permanent magnet synchronous generator [5] . The research targets of fault detection are mainly focused on a variety of models, such as a permanent magnet synchronous motor drives [6] , polytopic linear parameter-varying system [7] , heterogeneous multiagent LPV system [8] , linear discrete time-varying system [9] , and T-S fuzzy system with local nonlinear models [10] .…”

This paper studies an improved set-valued observer (SVO) for a complex model of a wind energy conversion system (WECS). To fit reality, an unknown function is used to describe the aerodynamic model, and a delay of the input signal is added to simulate the actual situation. The conservative SVO estimates the state error convergence within an adjustable interval. The extended Lipschitz condition, setinduced theory, and uniformly ultimately boundedness guarantees the convergence of errors. Based on the SVO, a fault detection system and corresponding fault detection strategies for common faults of WECSs are proposed. By adjusting the gain matrix L , the SVO shows excellent state tracking performance. The simulation results show that the proposed fault detection system can provide rapid and accurate fault detection.
