Abstract

The invention discloses an autonomous acquisition and intelligent control method for monitoring data of a DC power system. The method is characterized by comprising a step of collecting all remote signaling and remote measurement including AC voltage, charger voltage, charger current, bus voltage , load current, battery pack current, single battery voltage, single battery internal resistance and the operating status, branch switch status, feeder insulation status and abnormal alarm information of all DC equipment, a step of allowing a monitoring station to perform remote storage battery capacity verification test on a transmission station, wherein a charger is in a floating charge conversion, a step of achieving battery pack dynamic network reconstruction and voltage balance maintenance ona storage battery, and a step of providing server service and terminal software service for a remote monitoring system monitoring terminal. According to the invention, the remote discharge test, theremote bus state switching and other control operations are truly achieved, and a dynamic DC system simulation diagram is cooperated to visually display the main operating parameters of the DC systemand the working state of a feeder.

Description

technical field [0001] The invention relates to the technical field of battery management and control, in particular to a method for autonomous collection and intelligent management and control of monitoring data of a DC power supply system. Background technique [0002] According to the requirements of remote DC power system equipment status evaluation and analysis, currently, the scheme of power equipment status evaluation includes evaluation methods based on standard guidelines and scoring system, equipment fault diagnosis expert system based on limited data, self-learning diagnosis based on remote expert intervention system, and an expert system for equipment status evaluation based on multi-dimensional data and traditional machine learning. Traditional machine learning methods for equipment fault diagnosis are usually based on limited sample training to build a predictable relationship between input and output. Among them, the input volume and output volume are determi...
