Computer-aided analysis of distribution system: Design and implementation

Modeling and analysis of electrical distribution systems are not sophisticated at the present time worldwide. Recent developments in modeling techniques and computational algorithms have made a detailed analysis of a large scaled distribution system possible. Very many problems in the distribution area now can be studied by computer simulation. Since the new modeling techniques employ more parameters for each system component, and also the scale of the distribution system is usually very large, the data involved in a distribution system analysis will be tremendous. The old engineering approach to system analysis is no longer adequate. This dissertation provides a new approach to distribution system analysis. The issues in the design and implementation of such a system are also addressed.;This dissertation also developed a cable constants program to provide the data needed in system analysis. The program will supersede the transmission line constants program generally used by the utility, since underground cables are included. The cable constants program and other application programs are integrated into a distribution system analysis workstation by using current computer technology, so that the whole analysis process can be automatic. The users would be required to have little knowledge of the modeling and computational techniques. The proposed framework provides the overall structure for the development of the modern computer simulation package.
