Review of low voltage ride‐through technology of doubly‐fed induction generator

Wind energy currently represents a very important source of renewable energy sources (RESs). Among other RESs, Wind Energy Conversion Systems (WECS) with Doubly Fed Induction Generators (DFIG) have become more competitive globally. Due to their improved dynamic performance, flexible regulation of active and reactive power, superior power quality, variable speed operation, and four-quadrant converter operation. Grid-connected DFIG-based WECS are vulnerable to disruptions in the grid because of the direct connection of stator windings to the grid. The ability of the wind turbine (WT) to maintain connectivity during grid faults refers to the low-voltage ride-through (LVRT). When DFIG-based WTs are used to power networks, the grid codes require that they stay connected and support the stability of the system in a range of transient grid fault scenarios. As a result, DFIG-WTs are subjected to various protective measures to improve LVRT capacity. To increase DFIG's LVRT capabilities, a lot of good research has taken place in the literature. So, this study centers on exploring the recently emerging LVRT techniques for DFIG-WTs to help wind energy producers/operators select the appropriate technique through critical analysis. According to a wide range of articles, LVRT techniques can be classified into two groups: exterior and interior techniques; each group has its merits and demerits. Also, a thorough discussion has been made to assess the performance. Different case studies using

“…With the advancement in FACT technologies, the shunt and series controllers are used as a basic reactive power compensation. The Static Var Compensator (SVC) consists of Thyristor switched capacitors and Thyristor controlled reactors to inject the reactive power into the grid which enhances the transient performance and damp the power oscillations [15]. By using voltage source converters the Static Synchronous Compensator (STATCOM) is developed which injects or absorbs the reactive power from the grid to improve the voltage stability as shown in Fig.…”

“…A technical review of LVRT techniques applied in DFIG-WTs was discussed in Reference [4], while a significant portion was dedicated to LVRT protection circuits and hybrid combinations. In Reference [16], relevant literature about LVRT strategies was studied regarding when DFIG-WTs are connected to an alternating current (AC) network or voltage source converter (VSC) based high voltage direct current (HVDC). However, this paper mainly focused on the power surplus of two-terminal systems and DC voltage control of multi-terminal systems.…”

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.
