Application Of The Wavelet Analysis In The Fault Diagnosis Of Rotating Machines

With the rapid development of the national economy, China has invested heavily to transform to the distribution network, urban distribution network planning efforts have been a lot of new situations. Urban distribution network planning with a certain degree of complexity, urban distribution network planning is a difficult optimization problem. Geographic Information Systems GIS (Geography Information System) is a storage and processing spatial information, integration of databases, computer graphics and information systems in one high-tech, GIS-related attribute information and location to organically combine, according to actual needs, illustrated , accurate and real output to the user.GIS-based distribution network planning system provides the perfect graphic inquiry function of the distribution workers in the distribution network diagram, according to a variety of information distribution network and geographical information, for distribution network planning and engineering design, greatly improve the design efficiency. Geographical Information System platform, introduced into the distribution network planning systems, can greatly facilitate the planning of data management, while the planning process is more direct, more interactive. In this paper, analysis of GIS implementation principle as well as a network planning, demand analysis, based on detailed GIS-based distribution network planning, implementation.This article also directed at specific conditions of the analysis, decisions of the space system for auxiliary the study predicts module, a prose-style suited to our national conditions, and to programming cycle is based on parameters of the city with the network space. it is forecast to support the decisions of the site on research module for substations, to determine the position of parts made the investment and maintenance of the principles, and give a detailed a code.
