Efficient Control of Doubly Fed Induction Generator Wind Turbine Implementation in Matlab Simulink
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 7
Abstract
This paper presents an efficient control of Doubly Fed Induction Generator in variable speed wind power generation. The DFIGs are widely used in variable speed wind energy conversion system (WECS) because their voltage source converters only handle a fraction of the total output power under steady-state conditions. A backto-back power electronic converter (AC-DC-AC) is used in the rotor circuit of the DFIG, allowing the generator to work in both sub-synchronous and super-synchronous mode. In this work the control and implementation of the rotor, grid side and pitch angle controller is detailed. The aim of the grid side converter is to keep the dc-link voltage constant and also compensate the reactive power rather than providing an additional compensating device such as SVC or capacitors banks in parallel to the machine which leads to many problems such as over voltage. The rotor-side converter controls the rotor speed and allows decoupled control between the active reactive powers by using vector control technique. The pitch angle and rotor side controller will be control in coordination to prevent system failure during wind gust. The performance of the control system is demonstrate using Matlab Simulink.
