Embodiment Construction
[0021] Such as figure 1 As shown, a power grid line fault emergency repair scheduling simulation method includes steps:
[0022] S100: Obtain a grid structure topology map according to the grid line data.
[0023] Grid line data can be obtained based on historical experience data, for example, grid line data can be obtained from the existing grid line layout in a certain area. Of course, the power grid line data can also be obtained based on the grid line fault emergency repair scheduling simulation requirements. For example, this simulation needs to set N fault points, and the fault points are set in different locations. According to the power grid line data, the power grid structure topology diagram in this simulation can be obtained.
[0024] S200: According to the power grid structure topology diagram, set the types of switches in the power grid lines and the connection relationship between various types of switches and lines, and construct a power grid simulation line. ...

The invention provides a simulation method and system of the first-aid repair scheduling simulation of a power grid circuit fault. The simulation method comprises the following steps: according to power grid circuit data, obtaining a power grid structure topological graph; according to the power grid structure topological graph, setting switch types in the power grid circuit and a connection relationship between each type of switches and the circuit, and constructing a power grid simulation circuit; when the circuit fault on a certain position in the power grid is simulated, reading the state of the switch in the power grid simulation circuit, and generating a scheduling instruction; and according to the scheduling instruction, deploying first-aid personnel to a section switch to inspect and try to transmit a previous section of circuit, repeating the operation until the circuit in the power grid simulation circuit trips again, and determining a circuit section where faults happen. In the whole process, the power grid simulation circuit and fault simulation processing are constructed, and power grid workers can be trained to cause the power grid workers to be able to coordinate and cooperate as quickly as possible to quickly isolate faults and quickly recover power supply.
Description
technical field [0001] The invention relates to the technical field of power grids, in particular to a method and system for emergency repair dispatching simulation of grid line faults. Background technique [0002] With the improvement of people's living standards, the demand and dependence on electricity in production and life are increasing. At present, a complex and dense power transmission and distribution network has been built nationwide. For example, there are more than 1,000 10kV distribution network lines in a city-level area. After the medium-voltage full regulation and management is realized, the equipment required to supervise and command operations has doubled, and the number of distribution network line failures has also doubled. [0003] The fault handling of distribution network lines is a big problem. The suddenness, uncertainty and diversity of faults make distribution network dispatchers and power supply sub-bureaus very troublesome. In order to quickly ...
