Research on grid-connected stability control of full-power conversion wind turbine controlled by grid-side converter coupling voltage

<span lang="EN-US">The paper proposes a protection to dual stator generator, reluctance rotor, from asymmetrical fault. Which prevents the dual stator generator, reluctance rotor, from electrical sage through working process in order to avoid any interruption in the generator-grid connection. The procedure consummated with injecting suitable reactive power during the fault period. The proposed method that makes it possible for wind turbine application via dual stator winding generators (DSWRG) synchronous mod to stay connected to the grid during asymmetrical faults. It has been built according to trusted simulating mode considering all tested parameters according to experiment work. The expirment, consider the DC link side stability and care about the behavior and performance of machine side parameter. As well the machineability is evaluated to ride through asymmetrical fault by observing the secondary side current which has a big role in saving grid side converter. The control takes a response within 200 ms after fault trigger recognition. The generator ability of dynamically remaining connected stable and existing in the network, which is sustained a series voltage disturbance by injecting appropriate amount of reactive power. The main interest required in this paper is the capability of a machine to overcome the asymmetrical fault.</span>

Regulation of the terminal voltage of doubly fed induction generator (DFIG)-based wind energy conversion system (WECS) by modifying the control scheme of the grid side converter (GSC) is necessary compared to connecting alone flexible AC transmission systems (FACTS) and active power filter devices from economic point of view. An assessment study of GSC control strategy based both of static synchronous compensator (STATCOM) and shunt active power filter (SAPF) is introduced in this paper. STATCOM based AC voltage magnitude regulator and SAPF-based load calculations are controlled using space vector modulation (SVM) technique to maintain the terminal voltage of DFIG wind turbine constant when a grid disturbance happened. The system under study is modeled in MATLAB/Simulink environment. The simulation results under wind speed variation demonstrated that GSC-based STATCOM gives better results in regulation of the terminal voltage of DFIG compared to GSC-based SAPF and enhancement of the stability of this system.

Grid Side Converter

PurposeThis paper aims to provide a permanent magnet synchronous generator (PMSG) wind turbine, which feeds electric power (AC) to the power grid. The converter, located on the machine side, is used to produce the full amount of wind power. Research on wind energy conversion system (WECS) is carried out in this study using a direct wind turbine in MATLAB with constant and variable speeds.Design/methodology/approachThis paper is about WECS using PMSG and is connected to a grid of two serial converters with common DC connections.FindingsThis paper aims to provide the value of DC connection voltage at its base, regardless of the wind speed alterations, the inverter's output ac voltage can be kept constant.Originality/valueThis paper aims to provide a Hill Climb Search maximum power point tracking (MPPT) algorithm is an effective control system for extracting maximum energy, also called voltage control, pitch control, phase-locked loop (PLL) controls, from a wind turbine. Using the Fuzzy controller, the grid side converter is controlled.
