This paper deals with the application of artificial neural network to the transient stability assessment of a power system. The backpropagation technique is used to train the neural networks. The use of artificial neural network for computing critical clearing time and transient energy margin for a machine infinite bus system has been illustrated. In our enthusiastic investigations we found the ideas here proposed for a single machine will be the pioneer for extension of the same to the assessment of multi machine stability.

A magnetic bearing is a bearing that supports a load using magnetic levitation. Magnetic bearings accept moving parts without physical contact. For example, they are able to levitate a rotating shaft and allow relative movement with very low friction and without mechanical wear. Magnetic bearings withstand the highest speeds of all types of bearings and do not have a maximum relative speed. Passive magnetic bearings use permanent magnets and, therefore, do not require any input power, but are difficult to design beca ....etc

bridge bearing and stability ppt

Abstract

The designers of bridges must assure themselves that bridge bearings can transmit the high horizontal loads of current designs. The proportion of horizontal to vertical load is increasing due to the current trend toward continuous, joint free, redundant structures. From the 10 20% level of some years ago, horizontal forces are now found at and above the corresponding vertical loads. These horizontal forces require that bearing stability be investigated. Two levels of stability criteria, for normal c ....etc

Air bearings (also known as aerostatical or aerodynamical bearings) are bearings that use a thin film of pressurized air to provide an exceedingly low friction load-bearing interface between surfaces. The two surfaces do not touch. As they are contact-free, air bearings avoid the traditional bearing-related problems of friction, wear, particulates, and lubricant handling, and offer distinct advantages in precision positioning, such as lacking backlash and static friction, as well as in high-speed applications. ....etc
