Problems solved by technology

[0002] In order to ensure the reliability of power supply, most of the 10kV distribution network lines are in contact with one or more lines, and there are multiple power points. In the process of parallel power replacement and power outage replacement, operators such as power transformation and distribution are required to cooperate , if the commander is not familiar with the operation mode of the power grid at that time, it is easy to cause accidental power outage, wrong power transmission or low-voltage loop closure. Features, the existing operating system is still blank in terms of 10kV distribution network operation, the operation manager can only command the distribution network line operation according to the drawings and records, the subjective factors are serious, and there is a great security risk. This is also a 10kV voltage level power grid accident The number is much higher than the main reason for the number of voltage level accidents above 10kV

Embodiment Construction

[0020] A 10kV distribution network line pre-operation method, comprising the following steps:

[0021] Store the primary wiring diagram of the grid and several devices in the grid in the component database.

[0022] Based on the selected device, look up the device and the wires connected to the device in the component database.

[0023] Judging the charging state of the device and the line connected to the device, if the charging state is the same, search for other devices connected to the line in the component database, and then go to the previous step; otherwise, stop searching and obtain pre-operation control picture.

[0024] In the pre-operation control diagram, the equipment and lines with the same electrification status shall be displayed in the same color.

[0025] The present invention includes two functions of equipment electrification state judgment and equipment operation prompt and displacement. Through the interactive judgment between the pre-operation control ...

Abstract

The invention discloses a 10-kV grid distribution line pre-operating method and system. According to the grid distribution line pre-operating method and system, the states of interconnection switches, disconnectors, individual line user wire inlet switches, transformer substations, and power lines and lead-out wires of switching stations on a 10-kV grid distribution line can be accurately reflected, line connecting modes can be shown visually in the mode of diagrams, and the states of neighboring switches and disconnectors to be operated can be determined through programs. The 10-kV grid distribution line pre-operating method and system can simulate the situations of operations to be performed to play a role of ensuring correctness, avoid accidental power cut, accidental power supply or accidental loop closing, guarantee the operational security of the 10-kV grid distribution line and improve the power supply reliability.

Description

technical field [0001] The invention relates to the field of power distribution network, in particular to a 10kV distribution network line pre-operation method and system.
