Shaft voltage has become a serious problem in large power plants. This book assigns the potential sources of shaft voltage and its effects on bearings. The shaft voltages and bearing currents are due to the common mode voltage component of the output voltage from the static excitation system. The main objective of this book is to develop a gas turbine generator excitation-shaft-to-bearing model and simulate the model to investigate the shaft voltage and bearing current occurrence in a power station. To address the shaft voltage by using grounding brushes is proposed, the simulation of the...
