Controlled switching strategies for transformer inrush current reduction: A comparative study
(Elsevier, 2017-04)
Transformer inrush current can be efficiently mitigated by controlled switching. For energization of three-phase transformers, several strategies have been developed that depend on whether the residual flux can be measured ...

A Comprehensive VSG-based Onshore FRT Control Strategy for OWFs with VSC-MT-HVDC Transmission
(Institute of Electrical and Electronics Engineers, 2017)
This paper proposes a communication-free control strategy at the offshore wind farm (OWF) level to enhance onshore fault ride-through (FRT) grid code compliance of the voltage source converter (VSC)-based multi-terminal ...

Optimization of regular offshore wind-power plants using a non-discrete evolutionary algorithm
(AIMS Press, 2017)
Offshore wind farms (OWFs) often present a regular configuration mainly due to aesthetical considerations. This paper presents a new evolutionary algorithm that optimizes the location, configuration and orientation of ...

Grid-forming VSC control in four-wire systems with unbalanced nonlinear loads
(Elsevier, 2017)
A grid-forming voltage source converter (VSC) is responsible to hold voltage and frequency in autonomous operation of isolated systems. In the presence of unbalanced loads, a fourth leg is added to provide current path for ...

Open-Phase Fault-Tolerant Direct Torque Control Technique for Five-Phase Induction Motor Drives
(Institute of Electrical and Electronics Engineers, 2017-02)
Direct torque control (DTC) has been widely used as an alternative to traditional field-oriented control (FOC) methods for three-phase drives. The conventional DTC scheme has been successfully extended to multiphase ...
