Study And Practice On Voltage Upgrade Of Distribution Network In Dalateqi

Study and practice on voltage upgrade of distribution network is the important constituent which develops national economy and the society in the power supply region. Simultaneously also is important foundation of one electric power enterprising own long term development plan.In view of Physical circumstance of the Dalateqi, the paper chooses voltage upgrade of distribution network of Dalateqi, as the research object and analyzes the actuality distribution network of Dalateqi. On the basis of the application of the 20kV voltage level at home and abroad,combined with line loss rate, the voltage drop in the pressure lines, covering the comparison between the economic indicators index,demonstrated the necessity of the optimization of the sequence of voltage levels in planning and construction.The second is the load from the status and growth trends Dalateqi Banner proceed on the 20kV overhead lines, cables, boxes become selected, column change, switch design and selection of a detailed analysis and appraisal. Also studied the 20kV neutral grounding and boost reconstruction strategies and principles, and circuit construction of the project conducted a detailed analysis. Finally, from the direction of future development of distribution network starting on the construction of distribution network automation Dalate Banner goals, overall structure, the overall system of technical features and master the basic principles of construction of a concrete analysis of argument.This paper forecasted electrical load of power and the trend of distribution network of Dalateqi, in this foundation, study on voltage upgrade of distribution network, Proposed the relevant principles as voltage distribution network to upgrade has to be followed, finally concluded that the relevant recommendations. Through this article to the plan of voltage upgrade, Dalateqi electrical network each aspect all has strengthens, will be able to receive the very good social benefit and the economic efficiency, will be the Dalateqi next economic development and the society develops establishes the solid foundation.
