ANALYTICAL STUDY ON MODELLING OF Z-SOURCE CONVERTER WITH RESPECT TO ADVANCED TOPOLOGIES BASED ON WIND POWER CONVERSION SYSTEM

Abstract

A novel control drive for a switching reluctance generator (SRG) driven by a wind energy system is introduced in this work. For the first time, a model predictive control (MPC) technique is used to regulate the SRG in order to deliver the required voltage applied to the phase winding being fed by a z-source converter. Another MPC technique is utilized to run the converter immediately in order to as rapidly as possible follow the reference voltage of the segment before. In order to account for the SRG's nonlinear characteristics, the flux linkage and electromagnetic torque have been produced from the machine's finite element analysis and applied to the model. The generator's output power is enhanced in three different ways by this novel drive. Minimizing the phase current's rise-up time, keeping it in flat-top mode at all speeds, and making the most of the phase inductance's producing zone, or negative slope area. After the complete system is modelled in MATLAB-SIMULINK, the effectiveness of the recommended strategy is evaluated using the simulation results. There are several different topologies for permanent magnet generators, including radial flux, axial flux, and transverse flux PMGs. Due of the permanent axial flux generator's intricate design, large wind turbines cannot use it. Due to the simple design of the radial flux PMG, the manufacturing of many poles may be easily accommodated in the size of wind turbines. In order to overcome this problem, the research project recommends a unique topology quasi-Z-source Matrix converter-based DC/DC that uses a zigzag transformer. It is simulated and contrasted with other existing DC-based Z-source converters. DC will be certified from the start of the power supply unit in DC power supply systems.
