A station terminal sensing system and method

Abstract

The invention discloses a sensing system at the end of a station area, comprising: a meter box intelligent terminal, which is used to monitor the user terminal, determine the cause of the meter box power outage and identify the user load type, and send the power outage cause and the user load type to The main station; the intelligent terminal of the station area, which is installed on the side of the transformer outlet cabinet, and is used to monitor the intelligent terminal of the meter box and the station area, and determine the fault information of the station area, and send the fault information to the main station; and the main station , for receiving the power outage reason and user load type sent by the intelligent terminal of the meter box, and receiving the fault information sent by the intelligent terminal of the station area. The present invention adopts two layers of intelligent terminal equipment to collect fine-grained power consumption characteristic data, and realizes functions such as automatic identification of station area topology, station area fault location and responsibility definition, and non-intrusive load identification of users through feature identification and big data algorithms. Improve the management level and user experience of low-voltage station areas.

Description

technical field [0001] The invention relates to the field of smart grid and smart electricity utilization, in particular to a station terminal sensing system and method. Background technique [0002] With the development of smart grids, the growth rate of residents' electricity consumption is accelerating, and there are now problems such as a large number of residential electricity users, complex electricity consumption behaviors, difficult fault location, and low level of grid monitoring, including the following aspects: [0003] (1) The level of active perception of faults in residential station areas is low, and the troubleshooting time is long. The technical level of power outage fault handling in residential areas is still in the passive repair stage, and there are still problems such as inaccurate positioning and low level of accident responsibility identification; (2) The state perception level of the power grid in the station area is low, and the coverage of power qu...

AI Technical Summary

Problems solved by technology

The technical level of power outage fault handling in residential areas is still in the passive repair stage, and there are still problems such as inaccurate positioning and low level of accident responsibility identification; (2) The state perception level of the power grid in the station area is low, and the coverage of power quality monitoring equipment is limited. Poor real-time performance, insufficient ability to collect and analyze power quality data at the end of the grid (incoming lines of residential users), common problems such as unbalanced three-phase, high load rate, low voltage, excessive reactive power, etc., and lack of intelligent data analysis ; (3) Residential users have a low level of perception of power consumption status, and the existing technology has not deeply explored the value of fine-grained power consumption behavior data, and has not realized the identification of user power consumption load
