Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic flow chart illustrating main steps of a method for evaluating earthquake-resistant safety risk of a power grid facility according to an embodiment of the invention. As shown in fig. 1, the method for evaluating earthquake-resistant safety risk of power grid facilities in the embodiment of the present invention mainly includes the following steps:
s101, analyzing the seismic intensity of the position of the power grid facility during the earthquake;
s102, calculating safety coefficients of all power grid facilities in an earthquake influence range based on the earthquake intensity of the positions of the power grid facilities;
s103, risk assessment is carried out on all power grid facilities in the earthquake influence range based on the safety coefficients of all power grid facilities in the earthquake influence range.
In this embodiment, the seismic data sources required in the above process mainly include: on-site monitoring equipment, seismic network data and manual data. The system integrates and classifies the data. According to the time intensity and the like, the same earthquake event monitored by different monitoring devices can be combined.
In order to rapidly analyze the seismic intensity influence and display the seismic intensity influence on the system interface, in this embodiment, the step S101 may be implemented based on the following manner:
analyzing the earthquake influence range based on the earthquake motion peak acceleration of the observation points around the earthquake center;
selecting a reference point in the earthquake influence range, and calculating earthquake motion peak acceleration of the reference point;
on the basis of the seismic peak acceleration of the reference point, adopting a Krigin interpolation mode to interpolate values in the seismic influence range to render the seismic peak acceleration of different positions in the area;
and acquiring the seismic intensity corresponding to the seismic peak acceleration of the position of the power grid facility in the seismic influence range.
If the earthquake motion peak acceleration of the observation point is 0, the position of the observation point does not belong to the earthquake influence range, otherwise, the position of the observation point belongs to the earthquake influence range.
In one embodiment, for attenuation rules of various physical parameters in the seismic motion propagation process, a recommended attenuation model is provided in engineering site seismic safety evaluation (GB 17741-2005), that is, a calculation formula of seismic motion peak acceleration of observation points around the earthquake center is as follows:
lgA＝C1+C2M+C3M2+(C4+C5M)lg[R+C6 exp(C7M)]
in the above formula, A is the seismic peak acceleration of the observation point, C1、C2、C3、C4、C5、C6And C7All the parameters are regression parameters, M is earthquake intensity of the epicenter, R is a distance parameter between the epicenter and the observation point, the horizontal projection distance from the observation point to the epicenter is often adopted as an R value in the early attenuation model for statistical regression, but the simplification of the epicenter position to a point on a horizontal projection plane can cause larger fitting residual error due to complex earthquake causes, and in recent researches, the influence of factors such as earthquake focus depth, earthquake-induced fracture surface length and the like on the earthquake dynamic attenuation law is gradually emphasized.
Wherein, C6 exp(C7M) is a near field saturation factor used to introduce an increase in magnitude into the expression resulting in an increase in near field saturation range of seismic motion, typically determined in advance based on the source depth. C3M2The large earthquake saturation factor is used for introducing the increase of the earthquake motion saturation range under the large earthquake action in the expression. C2M is used to explain the acceleration enhancement phenomenon caused by the high frequency component of the strong seismic recording wave in the shallow source near-field earthquake.
The above formula contains 7 regression parameters in total, and the result of direct statistical regression still cannot meet the accuracy requirement of free surface motion evaluation, so that further assumptions and simplified models need to be provided. One commonly used method is to decouple the magnitude correlation factor and the distance parameter correlation factor in the model and then perform statistical regression step by step.
For a specific earthquake, the influence of the magnitude correlation factor on the attenuation model is small, so that the distance parameter correlation factor is subjected to statistical regression calculation, and the attenuation formula can be simplified as follows:
lgA＝C8+C9lg(R+C10)
wherein, C10＝C6 exp(C7M) in C for obtaining multiple earthquakes10Then, linear regression is carried out to obtain a coefficient C6And C7。
In one embodiment, the safety factor of all grid facilities within the seismic influence range is calculated as follows:
in the above formula, S is the safety coefficient of all power grid facilities in the earthquake influence range, FiEvaluation weight for ith grid facility, CiAnd H is the shock resistance coordination index of the power grid facility, and n is the total number of the power grid facilities in the earthquake influence range.
Wherein, when the shock resistance of each power grid facility is comparatively average, the H value is 1, and when the dispersion is great, the H value is less than 1. The specific value can be determined empirically according to the actual evaluation result, and if the difference between the minimum value and the mean value is greater than 30, the value is 0.6
In one embodiment, the type and structure of the power facility is substantially uniform, and is largely divided into two categories, i.e., in-station equipment and structures and ancillary facilities, as shown in fig. 2.
In earthquake damage assessment, each type of substation power facility is partitioned and classified. After corresponding physical and geometric simplification of each kind of electric power facility, the model shapes of different substations corresponding to the same kind of electric power facility are considered to be the same, and only the model shapes are different in size and material parameters. On the basis, each type of electric power facility is realized by utilizing a parameter programming modeling mode, and the modeling and calculation can be quickly carried out as long as corresponding size and material parameters are input, so that the earthquake damage assessment and visualization are completed.
The earthquake safety assessment of the substation comprises all elements within the range of the substation which affect the recovery function of the substation after the earthquake. During evaluation, factors with similar seismic damage characteristics are classified into one class, and seismic safety evaluation is performed on each class during evaluation. And giving different weights to the influence of each category on the overall earthquake resistance of the transformer substation, and evaluating the overall earthquake resistance of the transformer substation in a weighting mode. The weight coefficients of the substation earthquake safety risk assessment-assessment sub-items are shown in table 1.
