This book discusses the development of novel protective relaying algorithms using Mathematical Morphology, a nonlinear signal processing technique derived from set theory and geometry.

Professor Q.H. Wu is the chair of Electrical Engineering at The University of Liverpool, UK. He obtained an MSc(Eng) in Electrical Engineering from Huazhong University of Science and Technology (HUST), China and a PhD in Electrical Engineering from The Queen's University of Belfast (QUB). Before joining The University of Liverpool Professor Wu worked at both QUB and Loughborough University, UK. In 1994 he was awarded the Donald Julius Groen Prize for the best paper published in the Journal of Systems and Control Engineering, Institution of Mechanical Engineers. Professor Wu's research interests include systems modelling, adaptive control, mathematical morphology, evolutionary computation, multi-agent systems and their applications for power system operation and control. Z. Lu received an MSc(Eng) in Electrical Engineering from Huazhong University of Science and Technology, China. He obtained a PhD degree from The University of Liverpool and is currently a postdoctoral research associate with the Department of Electrical Engineering and Electronics at the university. His research areas include power system protection, mathematical morphology and evolutionary computation. T.Y. Ji has received a BA in English and an MSc(Eng) in Signal and Information Processing from Xi'an Jiaotong University, China. She is currently studying for a PhD at the Department of Electrical Engineering and Electronics, The University of Liverpool, UK. Her research areas include mathematical morphology, signal processing and evolutionary computation.
