Abstract

Reliable and sufficiently detailed data is required to facilitate decision making in all activities and distribution system management. Controlling costs improve efficiency and reducing down time has become essential for a utility in order to be successful in the highly competitive environment of today where private utilities / distribution companies are coming into distribution. With the huge connected networks, number of spur lines and alternative feeds from sources the creation, updating and management of distribution data is a Herculean task the data of distribution systems is maintained through hand-drawn maps with facilities data printed in text form on them and available with the JE/linesman in charge of the feeder. These maps are rarely updated. The use of advanced information technology tools for maintaining a coherent database thus becomes very essential.

Geographic Information system is a system of mapping of complete electrical network including low voltage system and customer supply points with latitude and longitudes overload on satellite imaging and/or survey of Indian maps. Layers of information are contained in these map representations .the first layer corresponds to the distribution network coverage. The second layer corresponds to the land background containing roads landmarks, buildings, rivers, and railway crossings etc. The next layer could contain information of the equipment viz poles conductors transformers etc. Most of the electrical network /equipment have a geographical location and the full benefit of any network improvement can be had only if the work is carried out in the geographical context. Event while doing something as relatively simple as adding a new service connection, it is vital to know that users of the system are not affected by this addition. gis in conjunction with system analysis tools helps to do just that.
