Strong wind early warning modeling method and strong wind early warning modeling system based on power grid GIS (geographic information system)

Abstract

The invention discloses a strong wind early warning modeling method and a strong wind early warning modeling system based on a power grid GIS (geographic information system). The strong wind early warning modeling method comprises the following steps of respectively establishing a strong wind weather chart layer and a power grid equipment chart layer in a platform of the power grid GIS; overlapping the power grid equipment chart layer and a monitored strong wind weather chart layer; establishing risk power grid equipment data in a strong wind influence scope; establishing association between the strong wind influence scope and the power grid equipment; producing different levels of early warning signals according to current real-time wind speed and wind resistant strength information of facilities of a power grid; generating power grid strong wind disaster early warning information; issuing the early warning information; and showing the generated power grid strong wind disaster early warning information by using the power grid GIS equipment chart layer. A professional power grid strong wind early warning model is established, precise monitoring, forecasting and early warning on the facilities and running of the power grid are implemented, a destructive effect on a disaster is reduced effectively, a pointed wind resistant measure standard can be formed, and loss of the power grid is reduced.

Description

Technical field [0001] The invention relates to the field of weather early warning of power grid GIS, in particular to a gale early warning modeling method and system based on power grid GIS. Background technique [0002] In the past, power grid equipment and weather early warning technology for safe operation did not have a professional early warning model for gales. High winds are one of the weather factors that have the greatest impact on grid GIS equipment and operation. Every spring and summer, grid equipment will be attacked by strong winds. Each strong wind will cause considerable damage to the local power grid. Establish a strong wind based on grid GIS The early warning model, assessing the damage caused by strong winds, making early warnings in advance, and reducing the harm of strong winds to the power grid is an important measure to improve the safety of power grid equipment. [0003] At present, there is no special gale disaster model for power grid facilities, and it ...

AI Technical Summary

Problems solved by technology

[0003] At present, there is no special strong wind disaster model for power grid facilities, and it is often necessary to spend a lot of manpower and material resources on regular or irregular maintenance of power grid equipment to prevent the impact of strong wind disasters on power grid equipment

For sudden gale disasters, timely early warning cannot be achieved, and the impact of various meteorological disasters on power grid equipment cannot be accurately and comprehensively monitored, let alone effective and effective preventive measures for gale disasters in a timely manner to minimize disaster losses
