Problems solved by technology

This is reflected in two aspects: First, the power grid failure is almost in a state of reporting by phone or manual detection. For example, if a certain line is powered off or equipment fails to work, the user must call to notify the power failure, or maintenance workers When a device failure is found, or the monitoring room finds that the line cannot operate normally, it is known that a failure has occurred, and the detection of the failure is in a passive state
Under normal circumstances, there will be a long period of time from the occurrence of the fault to the discovery of the accident, which will cause some unnecessary losses. If there is a large-scale power supply disorder or even a power outage, it will be impossible to respond quickly
Second, the equipment location and topology of the power grid network basically depend on human memory or construction drawings. Although with the popularization of computers, the location of power grid equipment and construction drawings are stored in computers, they only show the construction of the power grid and cannot Automatic fault detection
Obviously, the existing power grid fault detection method can no longer meet the needs of the current power grid and the rapid development of my country's economic construction.

Embodiment Construction

[0018] Accompanying drawing has provided a specific embodiment of the present invention.

[0019] In this method, all electrical equipment in the power grid is included in an automatic detection network, and the automatic detection network adopts a GIS geographic information system.

[0020] Analyzing the structure of the current urban distribution network, there are two types of overhead lines and cable lines. They have both common points and differences. The grids are closed-loop design and open-loop operation, which is radial. The overhead line has a tree structure and is divided into multiple feeder segments bounded by the segment switch / tie switch. Each feeder segment can be regarded as a subtree. The inside of the feeder segment is uncontrollable, only the switches on the boundary Controlled, install a fault detector at the switch. There are many branches of overhead lines, and one feeder may have multiple tie switches. The so-called tree structure means: in a certain ...

Abstract

The invention discloses an automatic detection method of an electric network failure, relating to the field of automatic control of computers. All sets of electric equipment in an electric network are recorded into a geographic information system (GIS) according to corresponding data of points and lines by the structural characteristic of a current urban electric network. Pole towers are set as point equipment; the middle of each two sets of point equipment is provided with line equipment; the point equipment is fixed on both ends of the line equipment; detection is carried out in a point-line-point-line-point mode by using one set of point equipment or line equipment as a starting point and a current direction as a reference; and connectivity analysis detection is carried out on downstream equipment of a power supply according to the voltage level of total power supply, comprising analysis detection of a power supply range, listing operation and disconnecting link operation. The method can be used for quickly detecting the failure of electric network equipment, connecting real-time monitoring equipment on the system, quickly and visually simulating an effect caused by a current accident state on a computer and providing treating proposals, and is convenient for managers to treat the failure of the whole electric network.

Description

technical field [0001] The invention relates to the field of computer automatic control, in particular to a method for automatic detection of grid faults. Background technique [0002] At present, the detection of power grid faults in cities in our country is still in a very backward state. This is reflected in two aspects: First, the power grid failure is almost in a state of reporting by phone or manual detection. For example, if a certain line is powered off or equipment fails to work, the user must call to notify the power failure, or maintenance workers When equipment failure is found, or the monitoring room finds that the line cannot operate normally, it is known that a failure has occurred, and the detection of the failure is in a passive state. Under normal circumstances, there will be a long period of time from the occurrence of the fault to the discovery of the accident, which will cause some unnecessary losses. If there is a large-scale power supply disorder or e...
