Abstract

According to the power transmission section generation method, the device, the storage medium and the computer equipment, provided by the application, the equipment set influenced by the change and the active power of each equipment are determined by detecting the change of the grid structure of the power grid in real time, so that the power transmission section range needing to be adjusted is accurately locked. And then determining at least one pre-constructed power transmission section based on the equipment set, and further calculating the limit value and the control value of each pre-constructed power transmission section after the medium adjustment index and the effective time of each pre-constructed power transmission section are determined. So as to ensure that the section definition is accurately matched with the current operation mode and avoid the monitoring failure problem. And generating and checking the transmission section data file based on the determined data, and transmitting the transmission section data file to a safe area when the checking is passed. The process replaces the traditional manual configuration by automatic closed-loop processing, so that the risk of manual update lag and misoperation is eliminated, and the accuracy of section calculation is ensured by standardized data auditing.
