![]() ![]() Vector control based on integrator and proportional controllers is also used in Refs. However, this method works with a variable switching frequency, which leads to an over sizing of the passive elements and variable switching losses. Most of the control methods for the Vienna converters are based on the current hysteresis control. Different control strategies are proposed. In order to improve the efficiency, reliability, and capacity of its energy conversion systems, several power converter topologies based on classic two-level VSI converters or the three-level converters, as illustrated in Figure 1, can be used.Īcademics and the industry have expressed interest in using Vienna rectifiers in wind power systems. Wind power conversion systems have seen continuous improvements over the past decades in terms of the drive system that changes from a semi-variable speed wind system based on the doubly fed induction generators (DIFG) to the direct drive full variable speed based on permanent magnet synchronous generator (PMSG), which represents the majority of the recent commercial systems produced by the manufacturers. Wind energy is the second most prevalent renewable energy type installed in the world, with 733 GW, which represents 26% of the global renewable electricity production, and the substantial investments in offshore wind turbines would allow competitive production costs and a significant increase in the installed capacity in the future. As a result, the production of energy through non-polluting and renewable processes has increased considerably. One of the most polluting domains today is the production of energy, hence the urgent need to change the method of energy production for more environmentally friendly production processes. The global awareness of the dangers and risks of warming on the environment and the repercussions of its effects on humanity pushes many countries in the world to set goals and carry out environmental policies in order to reduce emissions of greenhouse gas. The outcomes present interesting performances in terms of dynamics and stability. The feasibility and effectiveness of the proposed control strategy are evaluated through the simulations in MATLAB/Simulink and experimental tests based on a laboratory prototype. The main objective of this work is to evaluate the performance of the vector control strategy of the PMSG associated with the Vienna rectifier considering the real conditions of wind power systems. In this paper, a wind energy production system based on a Vienna rectifier and the permanent magnet synchronous generator (PMSG) is proposed. They can be an interesting solution for medium and large wind power systems as they have the advantage of a high power density compared to traditional two-level converters. Generally, they are used in applications with a high switching frequency, particularly in telecommunications, and their use in power generation systems is recent but promising. RAW files must be opened through Adobe Camera RAW and loaded into Photoshop to be accessible to Perfectly Clear.Vienna converters have several advantages, including low construction costs, improved total harmonics, and considerable reliability. Monochrome and CMYK images must be converted to RGB before using Perfectly Clear. ![]() Any image file that Photoshop or Lightroom can open and convert to this format may be used in Perfectly Clear. Perfectly Clear requires RGB-formatted images in either 8 or 16-bit color depth.
