Fuzzy Control Strategy

In order to most effectively utilize the wind energy and improve the eficiency of wind generation system，an optimum control strategy of doublyfed induction generators (DFIG) was proposed,which made the system operationfor both the maximum wind enemy captured below the rated wind speed．Based on the wind turbine characteristics and basic electromagnetic relationship of DFIG the mathematical models of the stator active power and reactive power of DFIG were derived to fulfill maximal wind energy capture and conversion．A dual-passage excitation fuzzy control strategy based on dynamic synchronous reference frame was applied to control the proposed optimal stator active and reactive power．The operational performan ces of the wind turbine system with DFIG with wind speed variation were analyzed an d compared by using Matlab/Simulink．The results show the correctness and feasibility of the proposed control strategy.

Energy Conversion Systems

To keep away from non-renewable fossil energy, clean and green wind energy is one of the sustainable sources in nature that produce the electrical power with no-fossil energy issues. The fastest growing type of renewable energy is the wind energy due to its free availability and environmental problems. Wind energy conversion systems (WECSs) assume a significant part in the new production of electric power from renewable sources. Due to the technical progress in the wind turbine manufacturing, we have many types of wind turbines in use around the world. Many kinds of generators were used in the WECS. In this paper a comparison between three types of generators exploited in WECSs will be introduced. These types are self-excited induction generators (SEIGs), doubly-fed induction generator (DFIGs) and switched reluctance generators (SRGs). The comparison between the generators includes the speed range of operation, fault sensitivity, power ratings and the suitable types of wind turbines used for the three generators, moreover the control techniques applied.

Abstract: Wind energy is one of the most important and promising sources of renewable energy all over the world. Throughout the globe, in the last, three- or four-decades generation of electricity from wind energy has created a wide interest. At the same time, there has been a rapid development of wind energy-related technology. The control and estimation of wind energy conversion systems constitute a vast subject and are more complex than those of dc drives. Induction generators are widely preferable in wind farms because of their brushless construction, robustness, low maintenance requirements, and self-protection against short circuits. Low cost, robustness, and ease of maintenance are attractive features of induction generators. With wind turbine and micro/mini-hydro generators as an alternative energy source, the induction generators are being considered as an alternative choice to well-developed synchronous generators because of their simplicity, ruggedness, little maintenance, price, brushless (in squirrel cage construction), absence of separate dc source, self-protection against severe overloads and short circuits. In isolated systems, squirrel cage induction generators with capacitor excitation, known as self-excited induction generators (SEIGs), are very popular. This paper presents a review of literature related to the present status of research work on self-excited induction generators (SEIG), their terminal voltage control strategies, and over the past years discussing the classification of induction generators, steady-state and transient analysis, voltage control aspects, and parallel operation of SEIG.
