Introductory Chapter: Power System Stability

Abstract

Among the various available energy systems, electrical energy is the most popular form, because it can be transported easily at high efficiency and reasonable cost from one place to the other. Electrical machine is a device that converts mechanical energy to electrical energy or vice versa. In the earlier case, the machine is known as a generator, while in the latter case, it is called a motor. The action of magnetic field is used in both machines for the conversion of energy from one form to the other. A power system is a network of components that is well designed and structured to efficiently transmit and distribute electrical energy produced by generators to locations where they are utilized. Generators, motors and other utility loads are connected by a power system.
