Has major problems
At present, historical data are mainly derived from each system through manual work in the establishment of a distribution network planning problem library of a power supply station, and the support degree of basic data is insufficient and the utilization efficiency of the data is low in comprehensive analysis. Comparison of implementation effects of different schemes in a planning stage requires a large amount of manual calculation, and especially simulation verification of load cutting of multi-circuit lines, the convertible power supply capacity of a communication line, the number of automatic segmented households, the number of households during construction power failure and the like cannot be quickly carried out by means of data such as the existing load and the number of households of the system, so that the optimal working quality of the multi-scheme is influenced. The item decision is made by simply relying on experience to sequence the item priorities, so that the investment effects of different item combinations are difficult to measure and calculate during decision making, and the efficient utilization of funds is not facilitated. The evaluation after the project implementation also lacks clear and fine data statistical indexes to carry out project effect analysis, and mostly only relies on the whole index comparison of a power grid in a long period range, so that the planning and organization level of the distribution network project are difficult to be accurately and scientifically evaluated.
The lack of a planning result display platform presents the planning results of a project library in the face of the challenges of current power grid development and information-based construction, and the power grid planning lacks an effective visual display platform to display the planning results of the project library at present, and cannot effectively support accurate planning, project audit and accurate investment of a distribution network.
