GIS mapping helps BSES locate power cables

BSES in Delhi, India is all ready to complete the GIS mapping of its power distribution network. Once GIS is in place, the discom will have accurate details on the locations of all its cables. BSES will receive satellite images of its distribution network from INSAT-1C, which will then be validated with the information gathered by the BSES surveyors with the help of a software.

What this means for consumers is, the duration of power cuts due to local faults will be reduced considerably once the complaint is lodged. Through PLCC (Power Line Carrier Communication), the discom’s staff will be able to receive communication signals via the electrical cables and easily identify the transformer causing the problem. The technology will also help prevent overburdening and burning out of transformers. GIS will also help implementation of an energy audit and help identify distribution of losses transformer-wise. The accuracy of losses registered will also be greatly enhanced. The GIS system will be integrated with the outage management system and also help the discom plan technical operations besides enabling load flow analysis, short circuit studies and effective management of the distribution network.

So far, BSES has mapped 16 of the total 21 districts covering over 16 lakh consumers. All 21 districts have been mapped up to the distribution centre levels. It hopes to complete the process in the rest of the districts in another five months. Streetlight poles will also be mapped under the system. Streetlights in Chandni Chowk, Darya Ganj, Shankar Road, Paharganj, Jhilmil and Nandnagri have already been mapped.
