This paper presents a theoretical analysis and experimental evaluation of the switched reluctance generator (SRG) for off-grid variable-speed wind energy applications. The detailed model, control parameters and operational characteristics of the SRG as well as variable-speed wind turbine are discussed. In order to drive the wind energy conversion system (WECS) to the point of maximum aerodynamic efficiency, a SRG power output feedback control strategy which optimized angle position-current chopping control cooperating PI regulator is proposed. The control strategy is also demonstrated by means of Matlab/Simulink. Moreover, an experimental test system is set up, which a cage induction machine is used to emulate the variable-speed wind turbine. The experimental results validate the proposed control strategy and confirm the SRG performance.

New Business

Wind energy has a long history but in the last decades the technological development and the increasing energy efficiency push this business on a top position for the installed renewable energy capacity worldwide. For a better understanding of the economic and ecologic analysis of the business into the wind energy sector, in this chapter, are presented the main principles and energy concepts related to renewable energy, especially for wind energy. The analysis is focused on the importance of the main elements of a wind turbine and its costs structure. The wind turbine is analyzed also along its lifecycle in order to identify the environmental impact from the row material extraction to the end of lifetime. The main objective of this chapter is to understand the importance of wind energy as a renewable energy and how to use the kinetic energy of wind in order to generate electric energy taking into account its efficiency and also its impact on the environment.
