Description
Measurement and Analysis of Overvoltages in Power Systems
Jianming Li, Professor, State Grid Corporation, China
A combination of theory and application, this book features practical tests and analytical techniques comprehensively with engineering practicality as its focus. Based on years of research and industry experience, the author introduces many scientific research methods such as overvoltage simulation studies, dynamic simulation experiment platform development and application, and overvoltage pattern recognition. Readers will get a good grounding in the various sources of overvoltages in power systems, methods in on-line measurements as well as explanations of overvoltage formation mechanisms and monitoring analysis methods.
*Systematically examines sources, online measurements, analytical techniques, and simulations of overvoltages, with an emphasis on engineering practicality
*Presents practical engineering examples analyzing overvoltages and improving system operation, based on field experiments and data analysis
*Features overvoltage simulations and waveform analysis in transmission systems
Measurement and Analysis of Overvoltages in Power Systems is intended as an all-in-one guide for engineers and researchers in power systems engineering. It can be used as a reference text for graduate students and lecturers of electrical engineering.
