Visualization apparatus for the single line diagram of distribution systems with easy monitoring of switchgear condition and power failure section

摘要

The present invention relates to a power distribution system based on a single line diagram that expresses a connection relationship between a central control room at a remote site and a power distribution line through a topology analysis unit (100), a tree structure unit (200) and a tree rearrangement unit (300) In the visualization apparatus, a close or open state of each of the switches is provided in real time from a FRTU (Feeder Remote Terminal Unit, 2) provided in each of a plurality of switches (G, 1) An open / close state collecting unit 400 for collecting open / close states; A static section collecting section 500 for collecting a static section of the distribution line caused by opening of the switch 1; A display unit for dynamically visualizing the states and the electrostatic interval data of each of the switches collected through the switch state collecting unit 400 and the static charge collecting unit 500 so that the power distribution system operator can easily identify them, (600), and further includes an open / close verifier (700) for verifying the status of each of the open / close devices separately from the FRTU for collecting the open or closed states of the open / close devices and displaying the open / The present invention relates to a power line visualization apparatus based on a single line drawing which is easy to monitor the state of a switch and an electrostatic section which are distinguished from each other by a state of switching on / The operator of the power distribution system of the present invention can easily identify the state of the switchgear and the power failure section and rely on the terminal device (FRTU) By further comprising a verification means separate from the means for sensing the state of the switch, there is an effect to verify easily the node status of the on state and the disconnection of the switch also in the distribution lines, and induced to perform a fault occurs recover quickly.
