John Ciufo, P. Eng.
Is a professional Electrical Engineer with over forty years of electric utility experience with a focus on protection and control (P&C) engineering. He has worked for Hydro One Inc., formerly Ontario Hydro from 1976 to 2010. Over the years, he has held many different positions in the P&C power system discipline. His experience includes engineering, power system reliability compliance, smart grid, asset management, development of strategies, policies, developing functional and design standards, cybersecurity, and digital stations. He completed his career with Hydro One as a Senior Manager – Protection & Control Strategies and Standards in Asset Management. In 2011, he became a principal owner of Ciufo & Cooperberg Consulting Inc. a consulting company that specializes in power system protection.
John has an extensive background in protection and control systems in the electric industry. He is a registered Professional Engineer in the Province of Ontario and was a member of the Northeast Power Coordinating Council (NPCC), Task Force on System Protection for 10 years, and a Vice‐Chair from January 2008 to January 2010. Was a member of the North American Electric Regulatory Corporation (NERC), System Protection and Control Subcommittee since May 2004, and was the Chair between the periods June 2008 to September 2010. He was on several NERC drafting teams developing protection and control‐related standards and has co‐authored several industry papers.
During his career at Ontario Hydro/Hydro One, he was instrumental in developing protection engineering application standards; protection philosophies and processes; transitioned the company from electromechanical designs to microprocessor‐based designs that resulted in significant cost savings; developed protection and control health indices and asset management processes; developed reliability compliance programs and processes; developed the company's cybersecurity compliance program, introduced and piloted digital station designs, transitioned the company from microwave to Digital Synchronous Optical Network (SONET) teleprotection systems, established, developed, and conducted internal company protection training, among other achievements.
John continues to be active in the industry and provides engineering services to many North American electric utilities. He is a Technical Advisor for the Centre for Energy Advancement Technological Innovations (CEATI) for the Protection and Control Group.
Aaron Cooperberg, Licensed Protection Engineer
Is professionally licensed to practice Power System Protection in the Province of Ontario. Upon graduation having specialized in Power Systems he began his career with Ontario Hydro in1977. He was assigned there to the protection engineering group responsible for the specification and design of protection systems. He spent 21 years working alongside Ontario Hydro's top experts in Power System protection engineering carrying out many protection system designs during the period of rapid expansion of Ontario's 500 kV transmission system and the construction of large multi‐unit Nuclear, Thermal and Hydraulic generation sites.
His last 13 years with Ontario Hydro and then Hydro One was focused on the Asset Management of the province's Protection Systems. Here he developed industry‐recognized Asset Management design and business case strategies for the proactive replacement of end‐of‐life protection systems. He has also led the team responsible for developing the technical requirements to connect multi‐tapped generation to Hydro One's Transmission and Distribution systems. He completed his career with Hydro One as a Senior Manager – Protection & Control Planning. In 2011, he became a principal owner of Ciufo & Cooperberg Consulting Inc. a consulting company that specializes in power system protection.
Aaron possesses an in‐depth knowledge of protection systems for transmission as well as generation having designed protection systems for nuclear and hydroelectric generation as well as transmission for the former Ontario Hydro. He provided expert testimony to the U.S–Canada Committee on the August 14th, 2003, blackout. He was on the NERC drafting team developing Protection and Control Standard PRC‐001 for Protection Coordination. He was a speaker at conferences on the topics of protection systems as well as Asset Management and has presented at CEATI and Electric Power Research Institute (EPRI). Aaron continues to be active in the industry providing engineering services to many North American electric utilities.
This book contains the accumulated experiences and practices used by the authors who have each, practiced protection engineering for over forty years.
Protection engineering is a specialty within the study of power system engineering. It is generally, not taught in engineering programs except for some specialized post‐graduate programs. Considering that every power system big, and small, regardless of voltage level, requires the application of protection systems; the authors felt that there was a gap in the industry, and there is a need for more protection system information and guidance for new protection practitioners.
Protection is a highly complex discipline requiring several years of specialized engineering development following graduation. Utilities typically resort to the recruitment of graduate power system engineers into the field of protection engineering. Historically, these recruits would gain the necessary experience and training while working along with seasoned engineers over many years as they gain confidence. This mentoring approach is becoming more difficult to implement. Specifically, this mentoring approach relies on several years of overlap which is becoming more difficult to attain as many experienced staff with lifelong knowledge have, or are retiring, leaving fewer, and fewer experienced mentors.
