ABSTRACT
Considering that almost all power generation and most of power demand relate to electric machines, their transient and dynamics affect the performance and stability of the power system. Previous chapters discussed the steady-state operation and behavior of AC and DC machines. This chapter discusses how disturbances or sudden changes (e.g., faults, sudden load changes or shifts, or sudden changes in network configurations or in supply voltages) can cause these machines to behave quite differently. During such transient periods, it often becomes very important to have a knowledge of machine behavior. This chapter provides a brief review of both the electrical transient behavior and the mechanical transient behavior (dynamic response) of AC and DC machines.
