The terms used herein are only for the purpose of describing the embodiments of the present disclosure and are not intended to limit the present disclosure.

[0043] The embodiments of the present disclosure are further described below in conjunction with the accompanying drawings.

[0044] Reference Figure 1 As shown, Figure 1 An optional flow chart of a reliability test method for flood control design of a city substation provided in an embodiment of the present disclosure, the reliability test method for flood control design of a city substation includes but is not limited to steps 101 to 105, and each step is introduced in turn below.

[0045] Step 101: Obtain actual rainstorm and flood process monitoring data.

[0046] Specifically, a rainstorm flood is a flood caused by heavy rainfall, which causes a rapid increase in the amount of water in rivers and a sharp rise in water levels. It is the most common and most threatening flood. It can be simply understood that a rainstorm flood refers to a flood caused by heavy rain.

[0047] Step 102: Analyze the flood control design reliability of the substation network using the measured rainstorm and flood process monitoring data to obtain a first flood control design reliability analysis result of the substation network under the measured rainstorm and flood process monitoring data.

[0048] Specifically, the flood control design reliability of the substation network is analyzed using the measured rainstorm and flood process monitoring data, and the first flood control design reliability analysis result of the substation network under the measured rainstorm and flood process monitoring data is obtained. The analysis of the flood control design reliability of the substation network based on the measured rainstorm and flood process monitoring data that have occurred in the city conforms to the actual situation of the substation network in the city, can improve the accuracy of the first flood control design reliability analysis result of the substation network, and improve the accuracy of the final flood control design reliability test result of the substation network.

[0049] Step 103: Select typical rainstorm and flood process monitoring data from the measured rainstorm and flood process monitoring data, use the typical rainstorm and flood process monitoring data to analyze the flood control design reliability of the substation network, and obtain the second flood control design reliability analysis result of the substation network under the typical rainstorm and flood process monitoring data.

[0050] Specifically, typical rainstorm and flood refer to measured rainstorm and flood that are representative and more likely to occur. Typical rainstorm and flood process monitoring data are selected from the measured rainstorm and flood process monitoring data, and the flood control design reliability of the substation network is analyzed using the typical rainstorm and flood process monitoring data to obtain the second flood control design reliability analysis results of the substation network under the typical rainstorm and flood process monitoring data. The flood control design reliability of the substation network is analyzed based on the typical rainstorm and flood process monitoring data that have occurred in the city, which conforms to the current changing environment of extreme rainstorms and floods and the rapid changes in the underlying surface of the city, and can improve the accuracy of the second flood control design reliability analysis results of the substation network, and improve the accuracy of the final flood control design reliability test results of the substation network.

[0051] In some embodiments, typical rainstorm and flood process monitoring data are selected from the measured rainstorm and flood process monitoring data, including: calculating the frequency of measured rainstorm and floods based on the measured rainstorm and flood process monitoring data, and sorting the frequency of measured rainstorm and floods from high to low, and taking the measured rainstorm and flood process monitoring data whose frequency of measured rainstorm and floods is before a preset ranking as typical rainstorm and flood process monitoring data.

[0052] It can be understood that by calculating the frequency of measured rainstorms and floods, sorting the frequencies of measured rainstorms and floods from high to low, and selecting the measured rainstorm and flood process monitoring data corresponding to the measured rainstorms and floods with high frequencies as the typical rainstorm and flood process monitoring data, the measured rainstorms and floods with higher frequencies are more representative and more likely to occur in the future, which can more accurately predict the possible rainstorm and flood events in the future, and improve the accuracy of the reliability analysis results of the second flood control design of the substation network. The measured rainstorm and flood process monitoring data corresponding to the measured rainstorm and floods with higher frequencies are more in line with the extreme rainstorms and floods and the rapid changes in the urban underlying surface under the current changing environment, and improve the accuracy of the reliability analysis results of the second flood control design of the substation network.

[0053] In some embodiments, the frequency of measured rainstorms and floods is calculated based on measured rainstorm and flood process monitoring data, including: obtaining the rainstorm and flood level and type of each measured rainstorm and flood from each measured rainstorm and flood process monitoring data, calculating the number of occurrences of the rainstorm and flood level and type of the measured rainstorm and flood within the recurrence period, counting the total number of occurrences of the rainstorm and flood levels and types of all measured rainstorm and floods within the recurrence period, calculating the proportion of the number of occurrences of the rainstorm and flood level and type of the measured rainstorm and flood within the recurrence period in the total number of occurrences, and obtaining the frequency of the measured rainstorm and flood.

[0054] It is understandable that the level and type of rainstorm floods can directly reflect the intensity and characteristics of rainfall, and comprehensive consideration of the level and type of rainstorm floods can more accurately predict possible rainstorm flood events in the future. The frequency of measured rainstorm floods is calculated based on the level and type of rainstorm floods of the measured rainstorm floods. The calculated frequency of measured rainstorm floods is more representative for accurately predicting possible rainstorm flood events in the future, and can improve the accuracy of the reliability analysis results of the second flood control design of the substation network.

[0055] Step 104: Integrate the adverse factors in the typical rainstorm and flood process monitoring data to form comprehensive rainstorm process monitoring data, use the comprehensive rainstorm process monitoring data to analyze the flood control design reliability of the substation network, and obtain the third flood control design reliability analysis result of the substation network under the comprehensive rainstorm process monitoring data.

[0056] In some embodiments, unfavorable factors in typical rainstorm flood process monitoring data include long duration of the rainstorm, high rainfall intensity of the rainstorm, and large total precipitation of the rainstorm.

[0057] It can be understood that the adverse factors of the monitoring data of various typical rainstorm and flood processes that have occurred in the city are integrated to form the comprehensive rainstorm process monitoring data that has occurred in the basin and may occur in the future. Based on this comprehensive rainstorm process monitoring data, the flood control design reliability of the substation network is analyzed, and the possible climate change in the future is taken into account, which improves the accuracy of the third flood control design reliability analysis results of the substation network, and improves the accuracy of the final flood control design reliability test results of the substation network.

[0058] In some embodiments, the flood prevention design reliability of the substation network includes whether the substation fails due to flooding, the order of substation failure due to flooding, the number of substations in the substation network that fail due to flooding, and the scale of substation failure. Figure 2 As shown, Figure 2 An optional flow chart for analyzing the flood control design reliability of a substation network provided in an embodiment of the present disclosure uses measured rainstorm and flood process monitoring data or typical rainstorm and flood process monitoring data or comprehensive rainstorm process monitoring data to analyze the flood control design reliability of a substation network, including but not limited to the following steps 201 to 204.

[0059] Step 201: Obtain the topological relationship of the substation network.

[0060] Step 202: Analyze and determine whether each substation in the substation network is flooded and ineffective based on the measured rainstorm and flood process monitoring data or the typical rainstorm and flood process monitoring data or the comprehensive rainstorm process monitoring data.

[0061] Step 203: Determine the order of substation flooding failure according to the topological relationship of the substation network and the water inflow direction of the river system in the basin.

[0062] Step 204: Analyze the number of substations that are flooded and failed in the substation network and the scale of substation failures in different time periods according to the topological relationship of the substation network.

[0063] Specifically, based on the measured rainstorm and flood process monitoring data or typical rainstorm and flood process monitoring data or comprehensive rainstorm process monitoring data, analyze and determine whether each substation in the substation network is flooded and failed. After determining whether each substation is flooded and failed, determine the order of substation flooding and failure based on whether each substation is flooded and failed, combined with the topological relationship of the substation network and the direction of water inflow of the river system in the basin. Based on whether each substation is flooded and failed, combined with the topological relationship of the substation network, analyze the number of substations that are flooded and failed in the substation network and the scale of substation failures in different time periods.

[0064] It can be understood that, firstly, based on the measured rainstorm and flood process monitoring data or the typical rainstorm and flood process monitoring data or the comprehensive rainstorm process monitoring data, it is analyzed and determined whether each substation in the substation network is flooded and failed, and then the flood control design reliability of the substation network is further analyzed, thus realizing the transition from the flood control design reliability analysis of a single substation site to the flood control design reliability analysis of the substation network. The analysis is more comprehensive, and the final flood control design reliability test results of the substation network are more accurate.

[0065] In some embodiments, reference Figure 3 As shown, Figure 3 The embodiments of the present disclosure provide Figure 2 An optional flowchart of step 202, based on measured rainstorm and flood process monitoring data or typical rainstorm and flood process monitoring data or comprehensive rainstorm process monitoring data, analyzes and determines whether each substation in the substation network is flooded and failed, including but not limited to the following steps 301 to 304.

[0066] Step 301: Acquire urban terrain and street view data, urban drainage network data, urban river and river terrain data, substation floor elevation data, and substation cable joint elevation data.

[0067] Step 302: For each substation in the substation network, determine the substation flood control standard according to the substation level.

[0068] Step 303: According to the measured rainstorm and flood process monitoring data or the typical rainstorm and flood process monitoring data or the comprehensive rainstorm process monitoring data, combined with the substation flood control standards, urban terrain and streetscape data, urban drainage network data, urban rivers and river terrain data, based on the inference formula method in the rainstorm runoff calculation chart, determine the design flood water level under the recurrence period.

[0069] Step 304: Compare the designed flood water level with the substation floor elevation data and the substation cable joint elevation data to determine whether each substation is flooded and fails.

[0070] Specifically, the design flood refers to the flood that is likely to occur in a local area and is planned for the design of flood control projects and meets the specified flood control design standards. The design flood is the maximum flood that flood control planning and flood control projects are expected to prevent.

[0071] It is understandable that the cable joint, as an important part of the substation, can accurately judge and determine whether each substation is submerged and failed by comparing the design flood water level with the substation cable joint elevation data. By comparing the design flood water level with the substation floor elevation data, it is determined whether each substation is submerged and failed, and then the final flood control design reliability test results of the substation network are obtained based on whether each substation is submerged and failed. The final flood control design reliability test results of the substation network are applied to the flood control design of the substation. The substation floor is raised according to the final flood control design reliability test results of the substation network. The final flood control design reliability test results of the substation network can effectively and accurately provide a basis for improving the flood control design of the substation. In addition, the design flood water level is comprehensively compared with the substation floor elevation data and the substation cable joint elevation data to determine whether each substation is submerged and failed, which improves the accuracy of the final flood control design reliability test results of the substation network.

[0072] In some embodiments, reference Figure 4 As shown, Figure 4 The embodiments of the present disclosure provide Figure 3 An optional flow chart of step 303, based on measured rainstorm and flood process monitoring data or typical rainstorm and flood process monitoring data or comprehensive rainstorm process monitoring data, combined with substation flood control standards, urban terrain and streetscape data, urban drainage network data, urban rivers and river terrain data, based on the inference formula method in the rainstorm runoff calculation chart, determines the design flood water level under the recurrence period, including but not limited to the following steps 401 to 404.

[0073] Step 401: Determine the recurrence period according to the substation flood control standard.

[0074] Step 402: Determine the rainstorm parameters based on the inference formula method in the rainstorm runoff calculation chart according to the measured rainstorm and flood process monitoring data or the typical rainstorm and flood process monitoring data or the comprehensive rainstorm process monitoring data, and calculate the designed rainstorm data according to the rainstorm parameters, recurrence period, urban terrain and streetscape data, urban drainage network data, urban river and river terrain data, and rainstorm contour map.

[0075] Step 403: Calculate the runoff and confluence using the inference formula method in the storm runoff calculation chart based on the designed storm data, urban topography and streetscape data, urban drainage network data, and urban rivers and river terrain data, and obtain the designed flood process line based on the runoff and confluence.

[0076] Step 404: extract the peak flow in the design flood process line, substitute the peak flow into the water level and flow relationship curve to calculate the design flood water level under the recurrence period.

[0077] Specifically, design rainstorm refers to the rainstorm that is planned for the design of flood control projects, meets the specified design standards, and is likely to occur locally. Design rainstorm is used to derive the design flood.

[0078] It can be understood that the design flood water level is calculated based on the measured rainstorm and flood process monitoring data or the typical rainstorm and flood process monitoring data or the comprehensive rainstorm process monitoring data, combined with the urban terrain and streetscape data, urban drainage network data, urban rivers and river terrain data. In addition to considering the rainfall intensity in the city, the design flood water level also takes into account the city’s topography and drainage conditions, which is in line with the actual situation and improves the accuracy of the calculated design flood water level.

[0079] In some embodiments, for each substation in the substation network, the substation flood control standard is determined according to the substation level, and the recurrence period is determined according to the substation flood control standard, wherein one substation corresponds to one recurrence period, and multiple different recurrence periods are obtained. According to the measured rainstorm flood process monitoring data or typical rainstorm flood process monitoring data or comprehensive rainstorm process monitoring data, the rainstorm parameters are determined based on the inference formula method in the rainstorm runoff calculation chart, and the design rainstorm data is calculated according to the rainstorm parameters, multiple different recurrence periods, urban terrain and streetscape data, urban drainage network data, urban rivers and river terrain data, and rainstorm contour map; according to the design rainstorm data, urban terrain and streetscape data, urban drainage network data, urban rivers and river terrain data, the inference formula method in the rainstorm runoff calculation chart is used to calculate the runoff and confluence, and the design flood process line is calculated according to the runoff and confluence; the peak flow in the design flood process line is extracted, and the peak flow is substituted into the water level and flow relationship curve to calculate the design flood water level under multiple different recurrence periods. By comparing the design flood water levels under multiple different return periods with the substation floor elevation data and substation cable joint elevation data, it is determined whether each substation will be flooded and fail under different return periods, and the final flood control design reliability test results of the substation network under multiple different return periods are obtained.

[0080] Step 105: The first flood control design reliability analysis result, the second flood control design reliability analysis result, and the third flood control design reliability analysis result are integrated to obtain a final flood control design reliability test result of the substation network.

[0081] It can be seen that the measured rainstorm and flood process monitoring data are obtained; the measured rainstorm and flood process monitoring data are used to analyze the flood control design reliability of the substation network, and the first flood control design reliability analysis result of the substation network under the measured rainstorm and flood process monitoring data is obtained; typical rainstorm and flood process monitoring data are selected from the measured rainstorm and flood process monitoring data, and the flood control design reliability of the substation network is analyzed using the typical rainstorm and flood process monitoring data, and the second flood control design reliability analysis result of the substation network under the typical rainstorm and flood process monitoring data is obtained; the adverse factors in the typical rainstorm and flood process monitoring data are integrated to form comprehensive rainstorm process monitoring data, and the flood control design reliability of the substation network is analyzed using the comprehensive rainstorm process monitoring data, and the third flood control design reliability analysis result of the substation network under the comprehensive rainstorm process monitoring data is obtained; the first flood control design reliability analysis result, the second flood control design reliability analysis result, and the third flood control design reliability analysis result are integrated to obtain the final flood control design reliability test result of the substation network. The reliability of flood control design of substation network is analyzed based on the monitoring data of typical rainstorm and flood processes that have occurred in the city, which is in line with the situation of extreme rainstorm and flood and rapid change of urban underlying surface under the current changing environment, and improves the accuracy of the final flood control design reliability test results of substation network. And the adverse factors of the monitoring data of typical rainstorm and flood processes that have occurred in the city are integrated to form the comprehensive rainstorm process monitoring data that has occurred in the basin and may occur in the future. The reliability of flood control design of substation network is analyzed based on this comprehensive rainstorm process monitoring data, taking into account the possible climate change in the future, and improving the accuracy of the final flood control design reliability test results of substation network. And the final flood control design reliability test results of substation network can be applied to the flood control design of substation, which can provide a basis for improving flood control design for substation effectively and accurately.

[0082] In some embodiments, measured rainstorm and flood process monitoring data, urban terrain and street view data, urban drainage network data, urban river and river terrain data, substation floor elevation data, substation cable joint elevation data, and substation network topological relationships are obtained. The measured rainstorm and flood process monitoring data are used to analyze the flood control design reliability of the substation network, and the first flood control design reliability analysis result of the substation network under the measured rainstorm and flood process monitoring data is obtained; according to the frequency of measured rainstorm and flood, typical rainstorm and flood process monitoring data are selected from the measured rainstorm and flood process monitoring data, and the flood control design reliability of the substation network is analyzed using the typical rainstorm and flood process monitoring data, and the second flood control design reliability analysis result of the substation network under the typical rainstorm and flood process monitoring data is obtained; the unfavorable factors in the typical rainstorm and flood process monitoring data include long duration of rainstorm, high rainfall intensity of rainstorm and large total precipitation of rainstorm, and the unfavorable factors in the typical rainstorm and flood process monitoring data are integrated to form comprehensive rainstorm process monitoring data, and the flood control design reliability of the substation network is analyzed using the comprehensive rainstorm process monitoring data, and the third flood control design reliability analysis result of the substation network under the comprehensive rainstorm process monitoring data is obtained; the first flood control design reliability analysis result, the second flood control design reliability analysis result and the third flood control design reliability analysis result are integrated to obtain the final flood control design reliability test result of the substation network.

[0083] Among them, the reliability of flood control design of substation network is analyzed using measured rainstorm and flood process monitoring data or typical rainstorm and flood process monitoring data or comprehensive rainstorm process monitoring data, including: analyzing and determining whether each substation in the substation network is flooded and failed according to the measured rainstorm and flood process monitoring data or typical rainstorm and flood process monitoring data or comprehensive rainstorm process monitoring data; determining the order of substation flooding and failure according to the topological relationship of the substation network and the direction of water inflow of the basin water system; analyzing the number of substations flooded and failed in the substation network and the scale of substation failures in different time periods according to the topological relationship of the substation network.
