This article describes firstly a wind power production line, principally a wind turbine constitutes her and brushless doubly fed induction generator (BDFIG). The models of these components are developed, and control objective of BDFIG is to achieve a dynamic performance similar to the doubly fed induction generator (DFIG) using a stator flux field oriented control (FOC) and direct power control (DPC) strategy. After, the simulation program using Matlab/Simulink has been developed. The performances of this strategy are evaluated and analyzed, so the results shows a good robustness great dynamic and a precision of speed.

“…Research into SMC for PMSGs illustrates the potential of this control method and accentuates SMCs promise as a candidate for achieving the goal of increasing the efficiency level in regards to MPPT. Results demonstrated by research involving the use of SMC with permanent magnet synchronous motors (PMSMs) and permanent magnet synchronous generators (PMSGs) continue to demonstrate the strength of SMC as a viable method for effective control of synchronous machines [10][11][12][13][14].…”
Abstract:The subject of this paper pertains to sliding mode control and its application in nonlinear electrical power systems as seen in wind energy conversion systems. Due to the robustness in dealing with unmodeled system dynamics, sliding mode control has been widely used in electrical power system applications. This paper presents first and high order sliding mode control schemes for permanent magnet synchronous generator-based wind energy conversion systems. The application of these methods for control using dynamic models of the d-axis and q-axis currents, as well as those of the high speed shaft rotational speed show a high level of efficiency in power extraction from a varying wind resource. Computer simulation results have shown the efficacy of the proposed sliding mode control approaches.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
