The article presents issues related to the possibility of using electric propulsion systems in units used to transport crews servicing wind towers at sea. Offshore wind energy issues are discussed. Proposals for electric propulsion systems that could be used on units for transporting crews servicing offshore wind farms are presented. The possibility of using purely electrical drive systems or hybrid drive systems operating in a diesel-electric configuration is analyzed. By observing the motion of real CTV units, based on the data from the MarineTraffic service, a mathematical simulation model was developed, for which a number of simulations were carried out in the Modelica environment. The developed mathematical model takes into account the dynamic loads acting on the ship’s hull, hydrodynamic resistances, electric and diesel propulsion systems’ properties together with their individual elements’ characteristics. The tests of the electric propulsion system showed reduced fuel consumption (approx. 60%) and harmful gas emissions to the atmosphere (approximately 70%) in relation to conventional, internal combustion engine propulsion.

“…First, the SM energies are calculated using measured voltages

and estimated capacitances

E_{x y h} = \frac{1}{2} \cdot C_{est - x y h} \cdot V_{c x y h}^{2}

The calculated energies are ranked in an ascending order

“…In recent times, modular multilevel converters (MMCs) have increased research attention due to the unique features of modularity, voltage scalability, fault‐tolerability, and potentiality to generate high power quality output waveforms [1, 2]. Owing to these pivotal characteristics, MMCs have triumphantly formed their way into commercial products in the areas of high‐voltage dc transmission, renewable energy integration, static compensator, railway traction systems, medium‐voltage motor drives, electric ship systems, and charging infrastructure for energy storage systems [2–9]. MMCs necessitate a complex control structure to effectuate the multiple control objectives such as output current control, capacitor voltage balancing (VB), inter‐arm voltage/energy balancing control, and circulating current (CC) suppression control [2, 3].…”

“…MMCs necessitate a complex control structure to effectuate the multiple control objectives such as output current control, capacitor voltage balancing (VB), inter‐arm voltage/energy balancing control, and circulating current (CC) suppression control [2, 3]. In the last decade, substantial research in terms of the submodule (SM) topologies, high‐performance control schemes, VB control methods, SM capacitor ripple minimisation schemes, and MMC derived hybrid topologies has been carried out to overcome the technical challenges associated with the operation and control [9–15].…”

“…The higher power demand of large vehicles require large magnets, thus making EVs more expensive. Hence, the current research is focused on the use of alternative motors like the less magnet motors [4], [5], or magnet less motors such as induction motors (IM) [6]- [8] and switched reluctance motors (SRM) [9], [10]. Compared to IM, SRM is more efficient and cheaper but have major disadvantages, like high vibration, noise and torque ripple.…”

This paper presents a new open-ended winding induction motor (OEWIM) based dual-motor differential fourwheel drive (D4WD) for the electric vehicle (EV). Constant speed operation through cruise control is achieved using direct torque control (DTC) algorithm. The redundant vectors are used in the switching vector selection of the DTC algorithm to achieve balanced battery currents. Fault-tolerant operation of the drive is demonstrated, where the EV will work with full torque even if one of the inverters in rear motor drive or front motor drive or both fail. The dynamic model of the proposed drive is presented. The proposed drive and fault-tolerant operation (FTO) is verified through simulation as per the FTP-75 driving cycle. An experimental prototype of the proposed drive is developed, and the above algorithms are verified experimentally as per the FTP-75 and HFET driving cycles. Both the simulation as well as the experimental results are presented, and these results agree with the theoretical observations. Stable operation of EV for the entire test cycle under normal operation, as well as inverter fault conditions, is demonstrated.
