Negative-Sequence Current Injection of Transmission Solar Farms
IEEE Transactions on Power Delivery, 2020Integrating 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, 2013This 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 ...

Negative-Sequence Current Injection for Fast Islanding Detection of a Distributed Resource Unit
IEEE Transactions on Power Electronics, 2008This paper presents an active islanding detection method for a distributed resource (DR) unit which is coupled to a utility grid through a three-phase voltage-sourced converter (VSC). The method is based on injecting a negative-sequence current through the VSC controller and detecting and quantifying the corresponding negative-sequence voltage at the ...

Symmetrical Components Observer for LPMM Back EMF Based on Negative-Sequence Current Injection
IEEE Transactions on Industrial Electronics, 2022Thrust 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.

Control aspects of the dynamic negative sequence current injection of type 4 wind turbines [PDF]
2014 IEEE PES General Meeting | Conference & Exposition, 2014 State-of-the-art distributed generation with a fully rated converter only injects positive sequence current into unbalanced faults. Recently, both publications and draft standards have suggested that the injection of negative sequence reactive current into unbalanced faults can have benefits for the power system.
