Abstract

The embodiment of the invention discloses a method, device and equipment for determining a line transferable power supply rate and a storage medium. The method comprises the following steps: acquiringa medium-voltage line single line diagram of a distribution network system; analyzing a contact line of a line in the medium-voltage line single-line diagram; and analyzing the power supply transfercapability of the contact line, and determining the power supply transfer rate of the line according to the power supply transfer capability of the contact line. According to the embodiment of the invention, the single line diagram of the medium-voltage line is divided into different contact lines by reading the single line diagram of the medium-voltage line, and the power supply transfer capability of each contact line is calculated, so that the power supply transfer rate of the whole line is determined. Automatic calculation of the line power supply transfer capability and the rotatable power supply rate is realized, and the determination efficiency of the power supply transfer capability is improved.

Description

technical field [0001] Embodiments of the present invention relate to power analysis technology, and in particular to a method, device, equipment and storage medium for determining a transferable power supply rate of a line. Background technique [0002] With the acceleration of social and economic development, the power grid is also facing the great challenge of rapid load growth brought about by urban development. Power grid planners need to grasp the load level and transferable power supply capacity of power lines in a timely and accurate manner, so as to guide the preparation of new and reconstructed project plans for distribution networks. [0003] At present, the analysis of the transferable power supply capacity of medium-voltage lines is carried out manually. The peak load time current is manually added, and the contact relationship is simply used to judge whether it can be transferred. It takes 20 minutes to calculate the transferable power supply capacity of each ...
