Negative-Sequence Current Injection of Transmission Solar Farms

IEEE Transactions on Power Delivery, 2020
Integrating solar generation brings about unique challenges in power system protection. Previous studies have found inverter-based resources featuring distinct fault responses compared to conventional generators. The reduction in fault current magnitude and lack of negative and zero sequence currents can fundamentally impact the way that the power ...

Impact of negative sequence current injection by wind power plants

2013 IEEE Power & Energy Society General Meeting, 2013
This paper presents an analysis of the impact from negative sequence current injection by wind power plants in power systems under steady-state and short-term unbalanced conditions, including faults. The separate positive and negative sequence current control capability of the grid-side converters of full scale converter type wind turbines may be ...

Symmetrical Components Observer for LPMM Back EMF Based on Negative-Sequence Current Injection

IEEE Transactions on Industrial Electronics, 2022
Thrust force ripple, including no-load detent force and electromagnetic thrust ripple, worsens the precision of the linear permanent magnet machine (LPMM) control system. This article focuses on the elimination of electromagnetic thrust ripple caused by the finite length of the LPMM mover core.

Negative-Sequence Second-Order Circulating Current Injection for Hybrid MMC Under Over-Modulation Conditions

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020
Due to the presence of full-bridge submodules (FBSMs), hybrid modular multilevel converters (HMMCs) consisting of FBSMs and half-bridge submodules (HBSMs) can work under the over-modulation conditions, which means that half of the dc voltage is less than the magnitude of the ac voltage.
