Abstract

The invention discloses a transformer substation waterlogging early-warning method and an early-warning system. The method comprises the steps of through calculating an idle space which is not occupied by a fixed object at different spatial heights in a transformer substation, establishing a relation function among a transformer substation water accumulating amount, the idle area and the spatial height; evaluating the highest water discharging capability of a transformer substation water discharging pipe network according to a water discharging pipe physical parameter in the transformer substation; according to a predicated water amount, the highest water discharging capability of the transformer substation water discharging pipe network and the water discharging capability of an emergencywater discharging facility, calculating the accumulated water discharging amount accumulated in the unit time of the transformer substation and the water level; and performing early-warning of transformer substation waterlogging according to the calculated transformer substation water accumulation amount and the water level. The method according to the invention can realize early-warning for transformer substation waterlogging, effectively guiding waterlogging preventing operation of the transformer substation, and reducing influence of a heavy rainfall disaster to a power grid enterprise anda total society.

Description

technical field [0001] The invention relates to a three-dimensional model-based early warning method for substation waterlogging, which belongs to the field of disaster prevention and reduction in electric power systems. Background technique [0002] In recent years, heavy rainfall events have continued to increase, and many cities in China have suffered from waterlogging disasters to varying degrees. Waterlogging has become one of the important disasters that threaten the safety of power grids. Substation shutdown accidents caused by waterlogging have caused huge economic losses and serious damages. social influence. [0003] Waterlogging in substations is mainly caused by two aspects: one is the backflow of external accumulated water. The reason for this kind of phenomenon is mainly due to the poor drainage of the city as a whole. At present, waterproof doors, sewer isolation and other measures in substation waterlogging prevention measures are mainly to deal with this pr...
