Transformer area voltage fault monitoring method and intelligent Internet-of-things agent device

Abstract

The invention relates to the technical field of edge computing, particularly provides a voltage fault monitoring method of a transformer area and an intelligent Internet-of-things agent device, and aims to solve a technical problem that the voltage of a line at the side of a power distribution transformer area is out of limit. The method comprises the following steps of acquiring detection data of each monitoring terminal in a transformer area through a local data acquisition interface; on the basis of the detection data of each monitoring terminal in the transformer area and the downloaded transformer area photovoltaic energy storage voltage out-of-limit control application program, whether a voltage out-of-limit fault occurs in photovoltaic energy storage in the transformer area being diagnosed; and if yes, stabilizing the photovoltaic energy storage voltage of the transformer area by using the downloaded transformer area photovoltaic energy storage voltage out-of-limit control application program, otherwise, continuously carrying out voltage out-of-limit fault diagnosis on the photovoltaic energy storage in the transformer area. According to the method, through distributed photovoltaic and energy storage optimization control adjustment, voltage out-of-limit of the line at the power distribution area side is prevented, and requirements of the power quality of the power grid in the area and the power generation income of the user are met while the photovoltaic power generation power of the user is not reduced.

Description

technical field [0001] The invention relates to the field of edge computing, in particular to a method for monitoring voltage faults in a station area and an intelligent agent device for the Internet of Things. Background technique [0002] After a large number of distributed photovoltaic power generation is connected to the grid, the development of the entire power distribution system will become an active network, which will cause changes in the system power flow and voltage distribution, especially if the voltage rises beyond the limit, and may cause the power flow to be delivered; and because the photovoltaic power supply The output is greatly affected by the weather, which may cause voltage fluctuations and flicker in the power distribution system. At the same time, the use of large-scale photovoltaic inverters will cause a large amount of power harmonic pollution, which will bring economic losses to power users in the distribution network. , while endangering the safe ...
