Branch box outgoing wire model and outgoing wire number automatic selection method, device and memory

Abstract

The invention discloses a branch box outgoing wire model and outgoing wire number automatic selection method, device and memory. The branch box outgoing wire model automatic selection method comprisesthe steps of determining a capacity allocation coefficient of incoming lines of each meter box according to the total number of users connected to each meter box; calculating the incoming line current of each meter box according to the total active power of each meter box and the capacity allocation coefficient of the corresponding meter box incoming lines; and selecting the incoming cable model,which is the branch box outgoing wire model, of each meter box according to the incoming current of each meter box,. The branch box outgoing wire number automatic selection method comprises the stepsof calculating the actual outgoing wire number of the branch box according to the remaining outgoing wire current of a low-voltage feeder cabinet, the incoming line current of the branch box and theoutgoing wire current of the branch box; and determining the branch box outgoing wire number to be selected according to the actual outgoing wire number of the branch box. The method, device and memory of the invention can substantially raise the working efficiency of distribution network design and reduce requirements for the profession competence of employees.

Description

technical field [0001] The invention relates to an automatic selection method, device and memory for the type and number of outgoing lines of a branch box, belonging to the technical field of distribution networks. Background technique [0002] The main process of distribution network design is 1. Design data acceptance 2. Load distribution 3. Engineering drawing 4. Estimated materials and other stages. In actual work, due to the drawing habits of architectural institutes and electric power design institutes in various places, the writing habits of power supply plan reply sheets of power supply companies in various places, and the uneven quality of developers, the drawing formats and load plan templates in various places are different. The difference makes the data docking process a process with high learning costs, and seriously slows down the design progress of the distribution network design. Contents of the invention [0003] The purpose of the present invention is to...
