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 ...

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.

Determining negative sequence currents of turbine generator rotors
2009 International Conference on Electrical Machines and Systems, 2009In parallel to their dynamic duty synchronous generators must be capable of bearing permanently an additional negative sequence current of up to 10% of the rated current according to the IEC 60034–1 standard. On turbine generators this does not only charge the damper winding but causes eddy currents and losses in the solid rotor iron in parallel.

Negative sequence current reduction for generator/turbine protection
Conference Record of the 1993 IEEE Industry Applications Conference Twenty-Eighth IAS Annual Meeting, 2002The authors present a feasible method for negative sequence current reduction at the generator terminal through a special function static VAr compensator (SVC). A specially designed fixed-capacitor thyristor-controlled reactor SVC is used. Computer simulation and laboratory test results show that it can effectively reduce negative sequence current at a

A digital distance relay using negative sequence current
IEEE Transactions on Power Delivery, 1990The configuration and performance of a recently developed digital distance relay using negative sequence current for remote backup protection are described. Since relays for remote backup protection are designed for remote faults, the fault current that is input to the relay is small due to the influence of current distribution factors.
