Abstract The paper presents the advanced control system of the wind energy conversion with a variable speed wind turbine. The considered system consists of a wind turbine with the permanent magnet synchronous generator (PMSG), machine side converter (MSC), grid side converter (GSC) and control circuits. The mathematical models of a wind turbine system, the PMSG generator and converters have been described. The control algorithms of the converter systems based on the methods of vector control have been applied. In the advanced control system of the machine side converter the optimal MPPT control method has been used. Additionally the pitch control scheme is included in order to achieve the limitation of maximum power and to prevent mechanical damage of the wind turbine. In the control system of the grid side converter the control of active and reactive power has been applied with the application of Voltage Oriented Control (VOC). The performance of the considered wind energy system has been studied by digital simulation. The results of simulation studies confirmed the good effectiveness of the considered wind turbine system and very good performance of the proposed methods of vector control and control systems.

<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.
