Research On Grid Accurate Planning Of Distribution Network Of Central Area Of Shi Jiazhuang

Distribution network is the most close to the masses of people's production and life, and face to the users directly, which is an important infrastructure to service the people's livelihood. In recent years, the increasing distribution network construction investment is used to improve the development level of the city distribution network. Therefore, the research on the urban distribution network accurate planning is of great significance.According to the distribution network planning and design technical guideline of state grid corporation, and drawing lessons from the international consulting results of distribution network, and introducing the advanced grid concept of distribution network planning, and combining the practical situation of distribution network, and adhering to build a new mode of distribution function, and setting up the new planning management, and building the concept of quality and efficient planning and design team, in order to improve power supply reliability as the goal, to strengthen the construction of a network frame and improve the level of equipment, to plan power distribution automation construction as a whole, gradually to solve the whole distribution network development lags behind, and the user power supply service level is not high question, in this paper, the thought of the development target differentiation, and design modulation, and equipment series standardization is proposed to build the reasonable structure, advanced technology, flexible, reliable, economic and efficient modern intelligent distribution network.Firstly, the present situation, development situation, existing problems of distribution network is introduced for subsequent chapters which research on the distribution network planning.Secondly, the "grid" accurate planning of distribution network is researched. According to the "bottom-up" approach, on the basis of land demand, according to classification of the local rules of different land properties and development depth of field, combining with the typical load forecasting model, carry out systematic load forecasting. According to the differentiated planning standard, the 10 k V net rack is research by different region, communications, power distribution automation system, protection configuration, etc, is considered and extend to the 110 k V power grid and pipeline layout planning.Finally, analyzing the existing problems in the distribution network planning and management deeply, the modern intelligent distribution network planning concept is proposed on the basis of the link-up municipal/network and the coordinated development of cities and counties grid, and the method of "Grid" accurate distribution network planning is used to establish the planning management mechanism of three dimensional system including the goals, organization, policies to proceed the distribution network planning.
