The use of wind energy is increasing due to rapid increase in energy consumption and rapid deployment of wind energy. Among different types of wind turbine generators, doubly fed induction generators are most widely used because of their low cost and capability to work in different wind speeds. On the other hand, doubly fed induction generators (DFIGs) are very sensitive to voltage drop. If a fault occurs in the network the voltage of DFIG terminal drops. So the rotor current increases and this may lead to damage DFIG converters. So, a protection system must be used to protect DFIG converters. One of the common schemes used to protect DFIGs is crowbar protection. In this paper, the effects of static volt ampere reactive compensator (SVC) on DFIG operation during voltage drop and crowbar protection are investigated in detail. Results show that by using SVC the voltage drop of DFIG terminal during grid faults decreases. Therefore, the operation time of crowbar decreases and the fault ride through capability of DFIG increases.

“…These proposed improvements are classified into two main classes. In the first class, DFIG performance is enhanced by coordination with other devices, as follows; static synchronous compensator (STATCOM) [3], static var compensator (SVC) [4], superconducting magnetic energy storage (SMES) [5], battery energy source system BESS [6] or a combination of STATCOM and BESS [7]. In the second class, inner controllers are improved by pinch angle control [8] non-linear control [9] or a fuzzy logic controller [10].…”

With increasing demand for energy, there is a growing tendency to employ renewable sources such as wind energy. Using large amounts of energy from wind arouses critical issues such as voltage variation and poor quality power supply. Several papers have been published on suggestions to improve performance of wind turbines during grid fault; however, to the authors' knowledge only a few papers address this problem with dynamic references. This paper presents the fuzzy adaptive theta particle swarm optimization (FAӨPSO)-based fuzzy controller applied to a doubly fed induction generator (DFIG) to operate at medium voltage. The proposed method attempted to determine required reactive power reference and active power amplification factors based on recommendations presented by the German Transmission Code 2007 and capability limits of the DFIG. Optimum values of membership functions were obtained by utilizing an FAӨPSO algorithm. This method improves voltage profile at the first instant besides during the grid fault. Moreover, aforementioned method also acts as an additional controller that could emerge with different inner controllers in the DFIG.

The use of grid codes to supply energy means that wind turbines must connect to grids under both normal and abnormal conditions. It is therefore necessary to implement a fast and efficient method to enable a wind turbine to safely carry through in faulty conditions. This paper employs an optimized double decouple synchronous reference frame phase locked loop (ODDSRF-PLL) to correctly detect the amplitude of grid voltage. Dynamic reactive power references are derived using a fuzzy logic controller (FLC) based on the output of ODDSRF-PLL and are fed into a hysteresis based direct power control (H-DPC). A fuzzy adaptive particle swarm optimization algorithm is used to determine the optimal bands for H-DPC to improve the performance of the static synchronous compensator (STATCOM). Besides FLC, reactive power reference correction is implemented in MATLAB and used to assign right values to reactive power references. The results demonstrate that the voltage profile is effectively improved under normal and grid fault conditions. When used with the proposed control scheme, it provides the wind generator with the ability to remain connected during voltage sags and to fulfill the demanding reactive power requirements imposed by recent grid codes.Keywords-Doubly fed induction generator (DFIG); Low voltage ride through (LVRT); fuzzy Adaptive particle swarm optimization (FAPSO); static synchronous compensator (STATCOM), direct power control (DPC), double decouple synchronous reference frame phase locked loop (ODDSRF-PLL)
