| In recent years, the relevant state departments have carried out to improve the urban and rural distribution network, the relevant experts and scholars of our country also focus on the power supply and distribution in the reliability of the research. Nationwide annexed to a lot of substation and quickly into the work of the state, for some of the old substation is reformed, making it more adapted to the needs of the modernization of the distribution, the efforts, our distribution network overall quality has been greatly improved. But with the accelerating pace of China’s economic construction, the rapid development of social economy for the production and life with power quality put forward higher requirements, the transmission and distribution networks still faces very great pressure. Therefore, the problem of power supply reliability has become the current problem we must study, enhance the reliability of power supply, to ensure the production and life of the electricity order, help to improve the social productivity and people’s living standards.This paper carries on the investigation in the Ordos area of all power supply bureau distribution network on the basis, analyzes the reliability level of the regional distribution network, summarizes the main factors of restricting the power supply reliability of Power Supply Bureau of Ordos, find out the main problems existing in the power supply system of the Ordos from the reduction in the power of production and life impact and reduce planned and unplanned outage times, reasonable to reduce the outage time, effectively reduce the power range of and for the specific problem, find out improve Erdos Power Supply Reliability of distribution network in the technical level and management level solution. The content is divided into five parts. The first part is the introduction, describes the background and origin of the concept and the reliability of distribution system, expounds the necessity of improving the power supply reliability of power grid at the same time, introduces the research status for the reliability of power supply and domestic and foreign advanced theories and experience; the second part introduces the related theory, introduces the basic concepts of power supply reliability the distribution network, assess the factors affecting the reliability of power supply and power supply reliability index; the third part is the part of the problem raised to Erdos Power Supply Bureau of power supply and power supply reliability data were collected and analyzed, on the basis of analysis of the true level of power supply reliability rate of Erdos Power Supply Bureau, to find out the reliability of power supply and the developed countries in the aspects of data the gap between the gap, according to the power supply reliability rate to find out the main reason of the relatively low; the fourth part is the solution The part of the problem is that the data of the power supply reliability in all areas of the Ordos power supply bureau is collected and analyzed. At the same time, analysis of the status of the classification of the reliability of the power supply bureau in Ordos, to find out the weak nodes. Aiming at improving the reliability of power supply in Erdos Power Supply Bureau effective measures, making power related departments and power companies can improve economic efficiency, and improve the social benefit. The fifth part is the conclusion part. |
