Method for planning fire-extinguishing emergency route of transformer substation

Abstract

The invention provides a method for planning a fire-extinguishing emergency route of a transformer substation. The method comprises the following steps: (S1) acquiring a three-dimensional live-actionsimulation model of the transformer substation, identifying high-voltage equipment in the transformer substation in the three-dimensional live-action simulation model, and identifying transformer substation roads in the three-dimensional live-action simulation model; (S2) setting constraints for restricting the passage aiming at each high-voltage equipment in the three-dimensional live-action simulation model according to the voltage grades and safety distances of the high-voltage equipment; (S3) calculating the passage width and height of each part of each transformer substation road according to the three-dimensional live-action simulation model and the constraints; (S4) identifying combustion source sites in the three-dimensional live-action simulation model; and (S5) acquiring the width and height of present fire-extinguishing equipment, and lifting channels from the entrance of the transformer substation to the combustion source sites. According to the method, a transformer substation model and the high-voltage equipment of the transformer substation are combined through the three-dimensional live-action simulation model, and the emergency route of the transformer substation is planned, so that the effective fire-extinguishing route is provided for fire companies.

Description

technical field [0001] The invention relates to the technical field of substation fire control, in particular to a method for planning a substation fire safety route. Background technique [0002] As the hub of the power grid, the substation plays a very important role in the power system. The substation is an important part of the stable operation of the power system. The building structure in the substation is complex and there are many equipments. When the equipment is in operation, it carries dangerous voltage. Some high-voltage equipment also has an electric field range. When a fire broke out in a substation, when the fire brigade entered the scene to fight the fire, the fire brigade was not familiar with the site conditions of the power station and could not accurately judge the safe path. Large-scale fire extinguishing equipment could not reach the fire source and could only carry out fire fighting at a distance. [0003] Existing substations are generally equipped w...

Problems solved by technology

When a fire broke out in a substation, when the fire brigade entered the scene to fight the fire, the fire brigade was not familiar with the site conditions of the power station and could not accurately judge the safe path. Large-scale fire extinguishing equipment could not reach the fire source and could only carry out fire fighting at a distance.

[0003] Existing substations are generally equipped with a video monitoring system, which can observe the actual situation on site through video, but generally only a few important areas are equipped with cameras, monitoring has dead ends, and the electric field range of high-voltage equipment is not given. At that time, large fire extinguishing equipment did not dare to enter the site casually
