Negative Sequence Current Control in Wind Power Plants With VSC-HVDC Connection
IEEE Transactions on Sustainable Energy, 2012 Large offshore wind power plants may have multi-MW wind turbine generators (WTG) equipped with full-scale converters (FSC) and voltage source converter (VSC) based high voltaage direct-current (HVDC) transmission for gridconnection. The power electronic converters in theWTG-FSC and the VSC-HVDC allow fast current control in the offshore grid.

A review of negative sequence current
2010 63rd Annual Conference for Protective Relay Engineers, 2010Sequence component analysis plays an essential role in analyzing power system faults and explaining some power system phenomena. It is very well known that negative sequence current could cause rotor damage, and that damage is highly detrimental to rotating machines such as motors and generators.

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 ...
