Research on the seismic damage assessment for substation and emergency resource allocation
In order to improve the timeliness of post-earthquake disaster damage assessment,generate emergency resource allocation plans high-efficiently,assist emergency command and decision-making,and improve the efficiency of power emergency response,this paper builds damage assessment models for 110 kV and 220 kV substation based on the vulnerability theory;A quantitative analysis model of earthquake-induced landslide risk is established based on NewMark theory;An emergency resource allocation method considering the impact of secondary landslide disaster is proposed.The earthquake disaster simulation and case analysis were carried out for a regional power grid,and the damage probability of three substations under the earthquake scenarios of magnitude 6,7 and 8 was quantitatively evaluated.The results show that the probability of damage to each substation under different earthquake damage ranges from 7%to 26%,and the magnitude and epicenter distance are the main factors affecting the degree of substation damage;The probability of earthquake-induced landslides and the risk value of roads are given,and the optimal planning of emergency resource allocation path under the magnitude 7 earthquake scenario is given by comprehensively considering the location of emergency personnel,warehouses and the risk value of roads near the power grid in the region.The research in this paper can provide assistance and support for post-earthquake resource allocation and command decision-making.
