Measurement and Analysis of Overvoltages
in Power Systems
With the rapid development of computer technology and power electronic technology,
the methods of measuring and analyzing overvoltages in power systems have changed
significantly.
In this book, by adopting digital simulation and entity dynamic simulation and by using a substantial amount of field-measured data, overvoltage parameters
are extracted and overvoltage patterns recognized.
The new concepts and methods of
overvoltage measurement in this book can be used to instruct companies and organizations about monitoring, recording and analyzing overvoltages so as to ensure secured
operation of the power system.
The book consists of eight chapters: Chapter 1 briefly introduces the overvoltage
mechanism; Chapter 2 relates to the acquisition system of overvoltage monitoring
devices; Chapter 3 deals with the transmission and recording system of overvoltage
monitoring devices; Chapter 4 studies the transient response of lightning waves;
Chapter 5 is concerned with typical field tests and waveform analysis for the UHVDC
transmission system; Chapter 6 is mainly about digital simulation; Chapter 7 relates
to entity dynamic simulation for overvoltages on transmission lines; and Chapter 8
provides details on overvoltage pattern recognition.
I am the chief editor of the book,
but experiments involved in this book, together with compilation and proofreading
were conducted cooperatively by Chen Shaoqing, Zhang Yu, He Xiangyu, Xu Wen,
Qin Dahai, Ren Xiaohua, Bi Yanqiu, Jiang Yuhan, Xie Shijun, Li Shuqi, Ouyang Renle,
Li Guoyi, Huang Yidan, Zhang Luo, Liu Yuqing, Chen Xin, Li Hewei, Zhou Yue, Yang
Hailong and Luo Yiqiao.
My heartfelt appreciation also goes to Professor Zeng Rong from Tsinghua University,
Professor Yang Qing from Chongqing University and Senior Engineer Cao Yongxing
from Sichuan Electric Power Research Institute, State Grid Corporation of China.
All of
them have provided a considerable amount of valuable advice related to the manuscript.
Errors and deficiencies may be found in the book due to my limited ability. Advice and
criticism are welcome
