The invention discloses a distribution network maintenance
single line diagram power failure range intelligent identification method based on an OCS
system, and the method comprises the steps: obtaining
single line diagram equipment information, automatically generating a
single line diagram, and carrying out the power failure range identification, and the step of obtaining the single line diagram equipment information, automatically generating the single line diagram comprises the following steps: initializing, obtaining an equipment
structure relation, and storing a topological relation. Initializing a
graph model, identifying
trunk lines, setting node coordinates,
processing cross and overlap, and generating an interactive single line graph; the power failure range identification comprises the following steps: establishing a switch
temporal database, performing real-time or regular analysis, simulating an equipment disconnection state, determining a power failure area range, collecting and preprocessing data, performing real-time monitoring and fault detection, and predicting the power failure range. According to the method for intelligently identifying the power failure range through the distribution network maintenance single line diagram based on the OCS, the efficiency and accuracy of power distribution network maintenance work are remarkably improved through intelligent and automatic means, and a powerful guarantee is provided for safe and stable operation of a power
system.
