Electric power three-phase balance strategy method for regulating and controlling Internet of Things based on intelligent network of electric devices

Abstract

The invention provides an electric power three-phase balance strategy method for regulating and controlling the Internet of Things based on an intelligent network of electric devices. The strategy comprises the steps that firstly, power utilization information such as power, current and voltage of each intelligent electric device is acquired; the phase of intelligent adjustable and controllable equipment is judged through the similarity between the power utilization voltage curve and the transformer voltage curve of a transformer area, so that the topological structure of a power system is obtained, the real-time three-phase imbalance characteristic of the power system is analyzed, and power utilization characteristic curves of the adjustable and controllable equipment in various working modes are constructed offline; and finally, according to the user instruction requirements of the adjustable and controllable equipment, an artificial intelligence algorithm is adopted to optimize thereal-time work instruction of the adjustable and controllable electric equipment. The three-phase imbalance degree of a local power grid is reduced. The method can be applied to multiple application scenes such as intelligent parks, intelligent buildings and intelligent power grids. The line loss is reduced on the premise that the user requirements are met, and the operation benefits and safety ofthe power grid are improved.

Description

technical field [0001] The invention belongs to the technical fields of smart grid and artificial intelligence, and in particular relates to a three-phase power balance strategy method based on an intelligent network of electric equipment for regulating and controlling the Internet of Things. Background technique [0002] my country's low-voltage distribution network generally adopts a three-phase four-wire connection method. Since the user side is mostly a single-phase load, and the power consumption is highly random, three-phase imbalances are prone to occur in the station area. Three-phase imbalance will not only cause problems such as reduced transformer usable capacity, shortened asset life, and increased line loss, but will also cause power quality degradation and lower customer satisfaction. At present, the following solutions are generally adopted for the three-phase unbalance problem at home and abroad: (1) Install a reactive power compensation device on the low-vol...
