| To ensure the needs of rapid economic development, development of power grid to the reasonable layout, appropriate in advance, in order to meet the needs of regional economic development and residential electricity demand, but because of the unbalanced development of regional industry adjustment, the power grid construction and practical difficulties, bureau of the Ministry of the regional power grid structure and layout are difficult to meet the growing use of electricity demand. The contradiction between electricity supply and demand is prominent, the safe operation of pressure, power quality is not stable, the access mode is complex, low reliability, accident treatment more difficult problems gradually emerged, on the one hand, with the country in recent years, power projects continue to invest in the construction of the power of the power shortage problem has been easing, another local card neck because of space truss structure reasons still exist, the peak occurs, the power supply reliability and power quality need to be improved.For an in-depth study and analysis of planning and development needs, improve the network structure, this will be the region as the research object, combined with the local history data of power consumption and economic growth in recent years, carry out a comprehensive analysis of power grid structure in the area of each voltage level, find out the main existing problems. Combined with the recent focus on local economic development planning and regional development, industrial, commercial, residential and other large pieces of analysis and forecast the electricity demand of society as a whole in the future 5-10 years in the region. According to the forecast results, focus on the development and improvement of local power grid need to wait a few aspects of the comprehensive consideration of electricity, the voltage level of the site, the line project construction principle, construction sequence of grid structure improvement and investment of construction funds and the project, provide a reference for the regional power grid structure improvement and development. |
