The health of a synchronous generator is challenged not only by internal faults, but also by external abnormal conditions. A comprehensive generator protection scheme against all possible threats can require a large number of relaying elements. Modern multi-function microprocessor-based relays offer a majority of these elements in a single device.
Often there is a tendency to apply all of them, which may lead to an overly designed protection system. In such systems, it may not be much of a concern that the relaying element might fail to operate when needed, but rather the relaying element might operate incorrectly. An incorrect protection operation not only disconnects a healthy machine from service, but also subjects the machine to unwanted wear and tear. The purpose of this tutorial is to provide a foundational understanding of commonly used relaying elements in generation protection and their corresponding coordination with other relaying elements.
The following specific topics related to generator protection will be discussed:
  • High resistance grounding,
  • Stator winding faults including differential,  ground fault, 100% ground fault and in-turn fault protections,
  • Rotor ground fault protection,
  • Capability curves and steady-state limits for salient and non-salient pole machines,
  • Abnormal conditions including loss of excitation, negative sequence overcurrent, out-of-step, off-nominal frequency operation, over-excitation, over-voltage, anti-motoring, inadvertent energization and open-pole flash over protections, and
  • Trip sequences including lockout and non-lockout with and without over-speed.

Dr. Mukesh Nagpal, Ph.D., P.Eng., Principal Engineer and Manager Protection and Control Planning Group – BC Hydro
Mukesh Nagpal received M.Sc and Ph.D degrees in electrical engineering from the University of Saskatchewan, Canada in 1986 and 1990, respectively. Dr. Nagpal is a senior member of IEEE and registered member of Association of Professional Engineers and Geoscientists of British Columbia, Canada.
Currently, he is a Principal Engineer and Manager of Protection and Control Planning Group within BC Hydro. He is also a part-time Professor with the University of British Columbia and a former part-time Instructor with the British Columbia Institute of Technology. He has about 28 years of experience in electrical consulting, utility research and power system protection. The majority of his experience is working with BC Hydro protection applications involving generators, transformers and high voltage transmission lines, including troubleshooting. 
Dr. Nagpal has written more than 40 technical papers on power system relaying. He has also contributed to numerous ANSI/IEEE sponsored standards or guides on relaying practices. His presentation received “Best-of-Show” award at BC Hydro’s 2007 P&C Telecom Annual Technical Conference. In 2007, he received BC Hydro’s prestigious “Mentorship Award” for his commitment to training and development of new engineers within and outside the organization. He was also winner also BC Hydro’s Ingenuity awards for two years: 2012 and 2013.
