Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] Such as figure 1 As shown, the present embodiment provides a GIS-based typhoon disaster risk assessment method for power grids, including the following steps:

[0033] Step S1: Collect typhoon data, geographic data and grid data;

[0034] Step S2: Establish the risk model of hazard-causing factors, the sensitivity model of disaster-forming environment, the vulnerability model of hazard-affected bodies, and the capacity model of disaster prevention and mitigation;

[0035] The hazard model of said hazard is:

[0036] V H =W H1 ·V H1 +W H2 ·V H2 ;

[0037] The disaster-forming environmental sensitivity model is:

[0038] V E =W E1 ·V E1 +W E2 ·V E2 +W E3 ·V E3 ;

[0039] The vulnerability model of the hazard-bearing body is:

[0040] V S =W S1 ·V S1 +W S2 ·V S2 +W S3 ·V S3 ;

[0041] The disaster prevention and mitigation ...

Abstract

The invention relates to a GIS-based typhoon disaster risk assessment method for a power grid. Through analysis and assessment of risk of typhoon, topographical sensitivity, fragility of the power grid and disaster prevention and mitigation capabilities, the typhoon disaster risk assessment method for the power grid is created. On one hand, compiling of a typhoon disaster risk zoning map for the power grid can be realized, and on the other hand, systematization and integrity of disaster risk division can be perfected to provide technical support for making a countermeasure for regional disaster prevention and mitigation.

Description

technical field [0001] The invention relates to the field of power grid disaster assessment and prediction, in particular to a GIS-based typhoon disaster risk assessment method for power grids. Background technique [0002] my country's mainland coastline is more than 18,000 kilometers long, and its special geographical location determines that typhoon disasters are frequent and serious in our country. Typhoons are one of the major natural disasters that threaten the safety of coastal power grid equipment and facilities. In 2006, the typhoon "Sangmei" caused all 13 110kV substations in Wenzhou to stop, 516 lines tripped and stopped, and more than 2,000 kilometers of high and low voltage lines were damaged. During the "Sudiro" typhoon in 2015, 2,801 lines (24.8%) of Fujian's 10kV public distribution network were damaged or out of service, and 68,789 distribution transformers were damaged or out of service (21.5%). Such severe weather seriously damages the interests of the p...
