Power wireless sensor network design method based on edge calculation

Abstract

The invention discloses a power wireless sensor network design method based on edge calculation. According to the invention, an intelligent distribution transformer terminal, a branch data monitoringterminal and a branch data monitoring unit are utilized to establish a power wireless sensor network in a low-voltage transformer area, electrical quantities such as current, voltage, power and electric quantity of a power distribution room and a meter box are acquired, and communication topology, segmented line loss and segmented impedance of the low-voltage power distribution network are obtained through an edge calculation algorithm. According to the invention, problems such as line loss abnormity can be positioned to the transformer area and subdivided to each branch outgoing line or meterbox, so that the problems of low voltage and line loss of the transformer area can be effectively solved and managed; software and hardware foundations and data support are laid for lean management and low-voltage governance work development of the low-voltage distribution area, manpower and material resources are saved, the power supply reliability is improved, user complaints are reduced, powersupply service quality is improved, and finally the purpose of orderly power utilization of the area is achieved.

Description

technical field [0001] The invention relates to the field of power distribution automation systems, in particular to a design method for a power wireless sensor network based on edge computing. Background technique [0002] In order to solve the problem that the status of low-voltage distribution lines and equipment cannot be effectively monitored, power failures at all levels such as station district / branch / meter box / household meter cannot be effectively reported, and problems such as three-phase unbalance, phase failure, and abnormal line loss can only be located in the station. It cannot be subdivided into each branch outlet or meter box, the switch status at all levels cannot be monitored, and the anomalies and faults of low-voltage lines / equipment cannot be accurately located. The concept of intelligent station area is proposed. At present, in the process of promoting the intelligent station area, how to carry out the lean management and low-voltage governance of the lo...
