Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 A synergetic control method is proposed to improve the fault ride through capability of front‐end speed regulation wind turbine (FESRWT). In case of three‐phase short‐circuit fault and single‐phase grounding fault, this method can accelerate the attenuation of stator flux transient component and restrain the fluctuation of rotor speed, make generator ...

Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 Power quality (PQ) is a key issue, particularly for technologically advanced process equipment, whose performance mainly depends on the quality of supply. Problems with PQ such as voltage swells/sags, interruptions, and harmonics are defined by any voltage, current, or frequency abnormalities causing damage or failure of the end‐user equipment. Outages

A static‐commutated device to contain voltage variations for low‐voltage active users
IET Electric Power Applications, Volume 15, Issue 8, Page 1095-1110, August 2021., 2021 Abstract The ever‐wider spread of distributed generation in distribution systems feeds the increasing demand for voltage regulation in low‐voltage networks. For these distribution grids, characterised by simpler structures than medium voltage systems but with a larger number of buses and feeders, voltage control devices have to guarantee fast and ...
