Designing of Sliding Mode Controller for Active and Reactive Power for Generator Connected to Network

Pages: 16-30


Doubly-Fed Induction Generators (DFIG) have recently attracted the attention of many users, and have also caused an increase in the demands, due to their special features and unique advantages. When this type of generator is in an unbalanced network, the voltage unbalance may lead to the disruptions in the generator’s function that can involve the generation of pulses in the, active, and reactive powers and electromagnetic torque, unbalance in the stator’s current, and finally, harmonization of the rotor’s current. One of the most remarkable approaches in designing a resistant controller is the sliding mode control. Clearly, controlling a system expressed by a first order differential equation is much simpler than controlling a system expressed by nth order differential equation. This feature is used in the sliding mode control, and using a conversion (sliding surface), it is shown that it can be possible to obtain a resistant control. In this research, the simulation of the suggested control strategy for DFIG-based wind power generation system is done by using MATLAB software. The most significant innovations that are realized by the current research are increasing the efficiency, optimizing the power coefficient, and increasing the quality and controlling maneuver by the sliding mode.
