Research Network Planning Shaoxing Paojiang Medium Voltage Distribution

With the rapid development of our economy, science and technology progress, at the same time, people more and more dependent on electric power, electric power market are often in short supply. But our power grid construction lags behind, such as the grid technology, grid structure relative to developed countries, is incomparable. Especially in the higher electricity requirement of Shaoxing, Zhejiang province, power grid planning research, especially in the area of medium voltage distribution network, the problem is particularly prominent. In order to solve the above problems, to strengthen the construction of the power grid is imminent.District distribution network planning, strengthening of Shaoxing, Zhejiang province, on the basis of the Shaoxing high-voltage power grid planning, combined with robe river new city development needs, the future load based on the existing distribution network, to do a good job of long-term power grid planning, is the electric power enterprises is very important to a job.This topic mainly studies Paojiang new area development of urban distribution network planning, from the time is divided into near future planning, medium-term planning and planning; From the space is divided into regional planning and zoning.Recent planning focus on present situation of power grid reliability assessment and equipment evaluation, find out the weak links. Medium-term planning and the main purpose of the vision is to determine the network frame, reserved site, channels, and corridors, for the recent planning target. The main contents include:1. according to the robe river new city development planning and the social development strategic target, to determine the development goals of the planning, the basic principle of general principles and construction transformation;2. analyze the robe river new city distribution network, points out the existing problems and guide in the near future planning and construction;3. determine the robe river new city middle load;4. the goal of medium voltage distribution network, determine the robe river new city development and the general principle;5. determine the medium-term and vision rack, under the condition of considering uncertainties in load forecasting and the development of load, the network frame of change and adapt to the way, which specific guidance distribution network construction; Calculation theory, the principle of voltage drop and reliability technology line loss.suggestions indicators, to ensure the safety of planning network frame.6. robe river new city medium voltage distribution network the budget of the investment;7. the robe river new city suggestion for medium voltage distribution network.
