“…Adaptive control scheme is presented in [3] to ensure the reliable operation of the permanent magnet synchronous generator under different operating conditions. This type of generator is interfaced with the grid through full-scale power converters, which increases the implementation cost [11]. The wound rotor induction generator (also called doubly fed induction generators (DFIG)) based wind turbine system has become popular due to the superior features of this type which include low cost, low converter rating, active and reactive power control, reduced losses and high efficiency [12].…”

Condition monitoring and early fault diagnosis for wind turbines have become essential industry practice as they help improve wind farm reliability, overall performance and productivity. If not detected and rectified at early stages, some faults can be catastrophic with significant loss or revenue along with interruption to the business relying mainly on wind energy. The failure of Wind turbine results in system downtime and repairing or replacement expenses that significantly reduce the annual income. Such failures call for more systematized operation and maintenance schemes to ensure the reliability of wind energy conversion systems. Condition monitoring and fault diagnosis systems of wind turbine play an important role in reducing maintenance and operational costs and increase system reliability. This paper is aimed at providing the reader with the overall feature for wind turbine condition monitoring and fault diagnosis which includes various potential fault types and locations along with the signals to be analyzed with different signal processing methods.

windmills may operate at variable speeds. 5 Because of variable speed operation and better performance, the doubly fed induction generator (DFIG) has been conventionally used in WECSs. However, permanent magnet synchronous generator (PMSG) has gained broad attention in wind energy applications due to its high efficiency operation, extended speed operating range, self-excitation capability, and leading to a high power factor. For obtaining high efficiency in WECS, it is essential to manage WT such that they can produce maximum power. MPPT algorithm is required for maximal power extraction from the wind energy sources (WES). 1,[6][7][8][9] The output of wind turbine generator (WTG) coupling are inherently unstable dc voltage. The unstable output of WTG contribute to the power quality and stability issues like voltage variations, harmonic generation, and flickers in the grid network. Unwanted harmonics are produced due to the presence of power converters. In addition, due to the varying wind speed, flicker or voltage variation occurs in output power supply. Thus, for the grid integration of WECS, the need of advanced power electronic converters (rectifier, boost converters, and inverters) under transient and steady-state operating condition configuration and their proficient control are necessary to standardize the converter output voltage, even under changing environmental conditions. 3,10 Nowadays, in this type of applications, the multilevel inverters are mostly used in comparison to elementary two-level inverters due to several advantages. [11][12][13][14] Among all standard MLI topologies, "cascaded H-bridge inverter (CHBI)" is primarily used for grid-integrated WECS applications owing to its simpler layout, modular design, reduced number of components as compared with other classical MLI topologies and the use of low voltage rated switches for achieving high or medium power level. [14][15][16][17][18][19] In proposed WECS, WTG coupled systems are connected to two individual H-bridges per phase of CHBMLI through isolated dc link along with respective independent boost converter-based maximum power point tracking (MPPT) system. In addition, by cascading these two H-bridges, the desired five-level output phase voltage is obtained.The major advantage of adopted CHBMLI topology possessing the isolated dc links plays the prominent role to legitimate in connecting two WECS with unequivocal power generation because of deviation of the wind speeds among the windmills at any point of time. In addition, this MLI support to adjoin two medium voltage WECS to feed the total power generated into the high voltage grid without any transformers, but at the same time, the system achieves the better synchronization along with calibrated and controlled power flow. It is an important note to consider that either the CHB topology used as an inverter or a rectifier the mandate of possessing equal dc link voltages is essential to justify identical permissible voltage stress among all switching devices in multilevel topologies at high ...

“…It was noted that the GAs-RSM gave better damping performance over the GRG approach to achieve the FRT capability of the wind farm.

The control techniques play a major role in the systems used to produce electricity from wind source. One of the important functions of the control systems is to determine the active and reactive powers supplied by the wind turbine to the grid. Conversely, the performance of the Wind energy conversion system (WECS) is affected by the varying grid condition. This paper presents a new application of bat optimization algorithm (BOA) to optimally design the proportional plus integral (PI) controllers of the interface converters of permeant magnet synchronous generator (PMSG)based wind turbine. The PMSG based on wind turbine is connected to the grid via a generator side converter, a DC link capacitor, and a grid side inverter. The response surface methodology (RSM) is implemented to model the voltage specification like undershoot, overshoot, steady state error and settling time. Multiple runs are performed on PSCAD program to create the RSM model. The BOA is applied to the RSM model to minimize the objective function. The simulation results are carried out using PSCAD program. The BOA results are compared with that obtained by using the grey wolf optimization (GWO) results. 1.
