“…In the 21st century, the leaders in the field of wind farms with HAWT were European companies (REpower, Vestas, Enercon, Siemens) ( Figure 1a). Synchronous generators (either singular or multiple) are the primary input of electrical energy [11]. Wind farms have started to be located offshore, where at a lower height of towers better wind conditions can be obtained.…”

This paper presents an overview of the DC link development and evolution dedicated to HVDC structure for connecting offshore wind power plants to onshore power systems. The growing demand for the green energy has forced investors in power industry to look for resources further out at sea. Hence, the development of power electronics and industrial engineering has enabled offshore wind farms to be situated further from the shore and in deeper waters. However, their development will require, among other technologies, DC-DC conversion systems. The advantages of HVDC over HVAC technology in relation to transmission distance are given. The different HVDC configurations and topologies of HVDC converters are elucidated. In this context, the HVDC grids are a promising alternative for the expansion of the existing AC grid.

“…Wind power generation systems, in the beginning, relayed on fixed or semi-fixed rotational velocity due to the usage of either synchronous generator (SG) or squirrel-cage induction generators (SCIG) that were connected to the grid directly [4], [5]. Generated power was controlled by the pitch of the wind turbine blades.…”

Fault-Tolerant Performance of the Novel Five-Phase Doubly-Fed Induction Generator

et al. 2022

The article presents the concept of a new design of a multiphase doubly-fed induction generator (DFIG). The innovative design approach is based on the use of a five-phase power supply from the rotor side of generator with a three-phase classic stator power supply. Modern three-phase doubly-fed induction generators are the dominant choice for Wind Energy Conversion Systems (WECS). Solutions of this type are sensitive to the loss of at least one phase of the power supply from the rotor side due to the failure of the rotor side inverter. The proposed design solution in the form of a multi-phase power supply in the rotor circuit is aimed at extending the range of possible failure-free operation of the generator system, and thus reducing system downtime as a result of failure of power electronic systems. The correctness of the adopted conceptual assumptions was confirmed by the results of laboratory tests. The main contribution is to prove that the use of five phase rotor winding significantly improves the overall reliability of the proposed electrical energy generation system.

“…The Multiple-Reference Frame Transformation (MRFT) was proposed to handle such situations and allow obtaining a time-invariant model. An average value model was often added to completely eliminate rotor position dependency in the transformed set of variables [20]. MRFT was applied to non-linear drive control [21], accurate estimation of torque ripple [22], and core loss calculation [23].…”

Novel ABC—Variable Based Closed-Form Analytical Model of Surface Mounted Permanent Magnet AC Machines With Sinusoidal and Non-Sinusoidal Back-EMF

This work presents a novel abc-based model applicable to surface-mounted permanent magnet AC (SM-PMAC) machines with sinusoidal and non-sinusoidal back-emf. It is capable of predicting the electromagnetic performance metrics such as torque waveforms, machine inductances, flux linkages and back-emf. The closed form expressions of the model, which can be evaluated with a high computational efficiency, are derived from basic geometric and winding parameters. Validation of the model is carried out numerically and experimentally with a very good match in results. Finally, the computational efficiency of the model is highlighted by considering a multi-objective evolutionary optimization design of SM-PMAC machine with a relatively large number of design parameters, where results are presented and discussed.
