The uniqueness of the electrical environment (asynchronous connection to power system, variable frequency operation, and harmonics) on the output of adjustable-speed drives (ASDs) requires special consideration to be given to the motor protection. The Working Group has investigated and addressed these concerns. This paper announces the report on the findings of this activity and the recommendation...Show More

S. Patel;K. Stephan;M. Bajpai;R. Das;T.J. Domin;E. Fennell;J.D. Gardell;I. Gibbs;C. Henville;P.M. Kerrigan;H.J. King;P. Kumar;C.J. Mozina;M. Reichard;J. Uchiyama;S. Usman;D. Viers;D. Wardlow;M. Yalla
Disturbance is an inherent part of any power system during the transition from one steady-state operating condition to the next. Protective relays may experience abnormal operating conditions during this transient period. This paper reviews various control actions that play a part during the transition and provides technical guidance to the industry on the application and setting of generator prot...Show More

The impact of large steel mill loads on power generating units
P. Solanics;K. Kozminski;M. Bajpai;J. Esztergalyos;E. Fennell;J. Gardell;C. Mozina;S. Patel;A. Pierce;V. Skendzic;P. Waudby;J. Williams
Large steel mills can be potentially harsh loads on an electric power system, producing harmonic currents and unbalanced system loading. Since these large loads are typically supplied from the EHV power system grid, it must be recognized that not only will the system of the host utility be impacted, but neighboring utility systems could be impacted as well. Existing IEEE Standard 519-1992, IEEE Re...Show More
Sequential tripping of steam turbine generators
E. Fennell;K. Kozminski;M. Bajpai;S. Easterday-McPadden;W. Elmore;C. Fromen;J. Gardell;W. Hartmann;J. Hurley;P. Kerrigan;K. Khunkhun;C. Mozina;G. Nail;S. Patel;G. Pence;A. Pierce;D. Smaha;S. Usman;P. Waudby;M. Yalla
The practice of tripping the generator breakers immediately following a boiler/turbine trip exposes a steam turbine generator to a potentially damaging overspeed operating condition. This paper describes the use of the sequential trip mode as a means of minimizing the exposure to possible unit damage following a boiler/turbine trip. Included is a comparison of the application of devices used by se...Show More
