A Space Saturation Load Forecasting Method and Tool

Abstract

The invention discloses a space saturation load forecasting method and tool. On the premise of not using other plug-ins, the tool is used to process plot maps based on graphics processing software and numbering software, and objectify common plot polylines. , add custom attributes, and number the plots, so that the graphic objects correspond to the table data one by one, then select the forecast data of the plot parameters and predict the saturated load in the future, and the forecast results can be easily used in the distribution network Plan other sessions. This method uses numbers to correspond the load forecast results with the plot objects in the graphics processing software one-to-one. Later, the maximum load in a certain area can be calculated by using the inter-industry simultaneity rate, which is convenient for positioning and troubleshooting when data processing errors occur, and the forecast results are unreasonable. real-time readjustment; all plot object data is managed by the tool in a unified manner, reducing the workload and the possibility of errors; avoiding the loss of some plot information in the traditional load forecasting method.

Description

technical field [0001] The invention relates to the technical field of power system load forecasting, in particular to a method and tool for space-saturated load forecasting. Background technique [0002] Long-term space saturated load forecasting is an important part of distribution network planning, and it is an important basis for substation layout, grid layout, and station channel planning. Site and planning grid evaluation play an important role. [0003] The traditional space load prediction is to export the plot data to an Excel table by means of a series of lisp small tools, after calculating the plot load, and then distribute the load result to the CAD file in the form of a single line of text. This method has three disadvantages: there is no direct correspondence between the load prediction results in the Excel table and the plot objects in the CAD file, and it is difficult to count the total load of the plots in a certain area; the load results distributed in the...

Problems solved by technology

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a space-saturated load forecasting method and tool, aiming to solve the difficulty in statistics of a certain area caused by the lack of strict correspondence between the plot object and the data in the traditional load forecasting method The problem of the total load of the plots, the need to manually switch between different software, the problems of low intelligence and loss of attribute information, as well as the inconvenience of positioning and troubleshooting when data processing errors occur, and the difficulty of adjusting prediction results
