Grid planning is an important part of the planning of the power system , the data required by the grid planning grid planning on the basis of these data is complete , accurate results will directly affect the load forecasting , but also will affect the rationality of the grid planning , economic and scientific . Large amount of data for the grid planning and difficult to collect , error-prone , bad management features , research and achieve grid the planning database management system , described in detail the structure of the grid planning the structure of the database and the data table , and finally focuses on a few main module form design program . Grid planning database using Visual Basic 6.0 as a major development tools , Microsoft SQL Server2000 database as a background . The system can be very convenient data add , delete , query , refresh , calculation of work and output the corresponding excel table . This can not only prevent the loss of data error , to facilitate the management , but also saves a lot of time , and reduce a lot of manpower and resources , but also provide a more detailed and precise data to planners . Planners analysis grid operating characteristics based on these data , found that the problems of the existing power grid to facilitate the rolling annual planning , to ensure the accuracy and scientific planning . Article also study the analysis of load forecasting method and programming , so you can easily load forecasting , using a computer program instead of a hand count , simple to operate , less error-prone . Urban distribution network planning and management system using a variety of load forecasting method , there are several ways of the law of natural growth rate , large users of natural growth rate , by industry , township Zoning counties partition coefficient of elasticity , gray theory method practical applications can be combined with the actual situation of the region , to select the appropriate forecasting method . Proven that the system has good practicality . Computer technology and network technology for the power grid planning system uses C / S ( Client / Server ) structure , grid planning , information collection management online , you can improve the backward planning means and methods , ideal for large planning \planning methods .
