Power Systems Dynamics

About the Book

This book is based on the author's course notes on the subject of power system dynamics, with emphasis on process simulation and control design methods. They were developed at home during the years the author was employed at the General Electric Co and later at Power Technologies Inc. as vice president and manager of consulting services. The course was given to over two thousand engineers worldwide. It is a valuable reference for engineers in the power industry.

About the Author

Mr. de Mello graduated with BS and MS degrees in Electrical Engineering from MIT where he was elected to Tau Beta Pi and Sigma Xi. His academic experience included several test engineering and laboratory assignments with the General Electric Company (GE) between 1945 and 1948. In 1948, he joined the Rio Light and Power Company in Brazil and over several years held positions of increasing technical responsibility in system planning and design studies concerning expansion of the Rio, Sao Paulo, and City of Santos systems. In 1955, Mr. de Mello joined the Analytical Engineering Section of GE’s Apparatus Sales Division in Schenectady. Here he undertook design and analysis studies of controls of industrial, power apparatus and aircraft power systems, making extensive use of analog computers. In 1959, he was assigned to specialized studies of dynamics of electrical machines, excitation control, prime-mover systems, and overall power systems. From 1961 to 1969, he conducted and guided extensive research efforts on modeling of dynamics of power systems and power plants for use in advanced boiler and plant control design studies. He made major pioneering contributions in the development of digital computer methods for dynamic analysis and process control design. Of particular note were the developments of computer techniques for the simulation of complex boiler dynamics and for the synthesis of multivariable boiler-turbine controls for which he was awarded GE’s Managerial and Ralph Cordiner Awards. He also made significant contributions in the study of electrical machine dynamics, their voltage and governing controls and to the analysis and implementation of system load-frequency controls. Mr. de Mello joined Power Technologies, Inc., at the time of its formation in August of 1969 as Principal Engineer, Dynamics and Control, and Secretary-Treasurer. He was appointed Vice President-Secretary in 1973. He was a Director of PTEL, PTI’s affiliate in Brazil. From 1974 to 1976, he was project manager for PTI and PTEL in system and design studies for transmission from Itaipu, the world’s largest 800 kV system and also served on the Advisory Board of the Study Group for Itaipu transmission. Prior to his appointment as Principal Consultant in 1987, he was Manager of PTI’s Consulting Services Department. Mr. de Mello has three patents and authored more than 100 technical papers in IEEE, ISA, American Power Conference, World Power Conference, and other utility industry publications, and also lectured to professional society groups. He has served on the IEEE System Controls Subcommittee and the joint IEEE Working Group on Plant Response and also served as US representative on CIGRE Study Committee 38. He teaches dynamic and operational subjects in PTI’s Power Technology Course. Mr. de Mello is a Fellow of IEEE, a Fellow of ISA, a member of the National Academy of Engineering, a registered Professional Engineer in New York State. He was a US representative on CIGRE Study Committees 38 and 39. He was awarded the IEEE Charles Concordia Award in 2003.
