Design and control of a quasi-Z-source inverter based for wind power generation using PMSG

Abstract

In this paper, a complete quasi-Z-source inverter based for wind power generation system is modelled and analysed. The overall system is introduced in two main configurations, one is open loop and the other is closed loop. The open loop system is designed in such away to extract the maximum wind energy from the open loop configuration using the modified Space Vector Pulse Width Modulation based on the maximum constant boost of the quasi Z source inverter. The closed loop system is used to control the dc link voltage. Results extracted from both cases are described, analyzed and compared. A 600 watt Permanent Magnet synchronous generator is used to generate the output power from the wind turbine. A complete MATLAB simulation for the analysis and design is introduced. A hardware setup of the wind turbine emulator coupled with the Permanent Magnet synchronous generator based on the Z-source inverter and controlled by the DSP TMS320F28335 is under construction for the hardware verification.

A critical review of research trends for wind energy in Egypt: recent progress and promising opportunities

“…Abdel-Rahim et al 2014introduced a WECS with a multiphase power generation and a matrix converter controlled via model predictive control. Hussein et al (2015) developed a model for a quasi-Z-source inverter to study the isolated load feed from PMSG WT in both open loop and closed loop operation modes.…”

Design and Implementation of Predictive Controllers on the Rectifier and Quasi Impedancesource Inverter in a Wind Energy Conversion System Based on Permanent Magnet Synchronous Generator

“…Proposed wind generation system based on PMSG with QZSI Generally, in standard wind power generation systems are employed different kinds of power electronic converters for various aims, rectifier in order to rectify the generator output, boost converter to enhance the output of the rectifier before feeding the inverter as the output of the inverter is evermore fewer than the input voltage and eventually the inverter to convert the dc / ac preparing power to the alternative load, in this standard system numerous converters are employed which result in decreased system efficiency and reliability. Moreover, dead time available in among switches of each leg makes distortion in the output waveform [22].…”

“…As well as, QZSI can be used to intensify the general system performance. The QZSI can execute both the boost and inversion action; consequently the boost converter can be deleted [22]. Therefore, total cost is reduced and weight of system as well as is declined.…”

Ride‐through strategy of quasi‐Z‐source wind power generation system under the asymmetrical grid voltage fault

“…In [21], a new controller is researched which can provide the constant voltage through adjusting the shoot-through duty cycle of q-ZSI. In summary, the current study of impedance-source WPGS is confined to MPPT, grid-connected control and LVRT during the symmetrical fault; there are few research about the LVRT for impedance-source WPGS during the asymmetrical fault of grid voltage [17][18][19][20][21][22]. However, asymmetrical fault of grid voltage is more common in the power system, compared with the symmetrical fault.…”
