Embodiment 1

[0047] This embodiment provides a visualized power grid system, including: a substation data subsystem, a geographic data subsystem, and a fault identification subsystem.

[0048] The substation data subsystem is used to establish a visual information map of the substation based on the model of the substation in the power grid and the three-dimensional real photo of the substation, so as to provide substation information and real-time operation data of the substation. The substation visualization information map can display substation information and real-time operation data of the substation on the display screen.

[0049]The process of establishing the visual information map of the substation is as follows: taking the 220KV substation as an example, according to the model of the substation, an expandable model library and virtual scene are established, and at the same time combined with the real photos of the substation, the real photos are professional SLR The panoramic cam...

Embodiment 2

[0057] This embodiment provides a fault identification method for a visualized power grid system, so as to find faults and deal with faults as soon as possible. The method includes:

[0058] S201: Collect real-time operation data of substations in the power grid;

[0059] Through the fault identification subsystem, the real-time operation data of the substation in the power grid is collected, and the data includes information such as frequency, generator power, line power and bus voltage.

[0060] S202: Determine whether the substation is faulty, and if the substation is faulty, determine the location of the fault;

[0061] The process of judging whether a substation is faulty is specifically: comparing the real-time data of the substation with a preset value, and when the real-time data is greater than the preset value, the substation is faulty. Taking the main transformer overrun fault as an example, after collecting the real-time data of the main transformer, compare the r...

Abstract

The invention provides a visual grid system and a fault identification method thereof. A visual information graph of a transformer substation and a visual geographic information graph of a grid are built, the position of the faulted transformer substation and the position of a faulted device are marked on the visual geographic information graph of the grid and the visual information graph of the transformer substation respectively when the transformer substation is faulted, so that a dispatcher can rapidly and directly obtain information of the positions of the faulted transformer substation and the faulted device, faults are rapidly isolated and recovered, and fault loss is decreased.

Description

technical field [0001] The invention relates to the technical field of power systems, and more specifically, to a visualized power grid system and a fault identification method thereof. Background technique [0002] The traditional SCADA (Supervisory Control And Data Acquisition, data acquisition and monitoring control system) / EMS (Energy Management System, energy management system) system is a modern power integrated automation system based on computer technology, mainly used in regional power grids And the provincial and municipal power grid dispatching centers provide various real-time information of the power grid for the power grid dispatching managers, including information such as frequency, generator power, line power and bus voltage, and carry out dispatching decision-making management and control of the power grid to ensure the power grid Safe operation, improve the quality of power grid and improve the economy of power grid operation. [0003] Because the traditi...
