Abstract: When a hybrid wind farm based on doubly fed induction generator (DFIG) and fixed speed induction generator (FSIG) is connected to an unbalanced network, most of the negative sequence current caused by the unbalanced grid…

Abstract: When the single-phase reclosing of the high-voltage circuit, there will be tremendous negative sequence current generation. The connection of inverter-type new energy sources may increase the negative sequence current of the power system. The risks…

Abstract: Because the traditional zero-sequence overcurrent protection method is not effective in detecting single-phase-to-ground faults (SPGF) in a low-resistance grounded system (LRGS), this paper analyzes the fault characteristics of a 10-kV LRGS in detail. From the…

Abstract: In this paper, a new zero-sequence current suppression control strategy for the five-phase open-winding fault-tolerant fractional-slot concentrated-winding interior-permanent-magnet (FTFSCW-IPM) motor drive system with a common dc bus is proposed. By unequal distribution of the zero…

Abstract: In this paper, the model predictive current control is introduced in the semicontrolled open-winding permanent magnet synchronous motor (OW-PMSM) generation system with a common dc bus to suppress the zero-sequence current for the first time.…

Abstract: In this work, we develop a zero-sequence model to analyze the zero-sequence current, i.e., circulating current, in multiple paralleled power converters. On this basis, we propose and verify a novel and simple solution: predictive zero-sequence…

DOI: 10.1109/tie.2022.3186317
Abstract: In this article, we propose a negative-sequence current compensation-based coordinated control strategy for dual-cage-rotor brushless doubly fed induction generator, where the machine-side converter (MSC) and the grid-side converter (GSC) cooperate to mitigate the imbalance in…
