[0040] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] Power fault recording is a waveform record that records the changes of multiple variables in the transient process of the power system over time. The recording file of power fault recording is an important data for research and analysis of power grid characteristics.

[0042] The traditional method of processing power data is to generate a recording file based on the collected power data information. The recording file specifies the name, sampling rate, number of points, and data information of each recording curve set. However, some important information that is beneficial to recording analysis, such as the displacement data in the curve, is a problem that users are very concerned about. However, the existing recording files do not reflect this information, and the recording analysis software needs to be manually calculated by the user after reading the recording file. Therefore, the existing power data processing method will affect the efficiency of data analysis.

[0043] Based on this, it is necessary to provide a power data processing method, device, equipment and storage medium for the above-mentioned technical problems. In the power data processing method, by obtaining curve data corresponding to the target power fault recording curve, the curve data includes power data values ​​measured at multiple sampling times, which are used to fit the target power fault recording curve. Then, for each sampling time in the curve data, based on the target detection strategy, the change of the power data value corresponding to the sampling time compared with the power data value corresponding to the target sampling time is detected. The target sampling time is the sampling time before the sampling time or the sampling time after the sampling time. According to the change of the power data value corresponding to each sampling time, the turning sampling time and the power data value corresponding to the turning sampling time are determined from the curve data, and the starting sampling time, turning sampling time, ending sampling time, and the power data values ​​corresponding to the starting sampling time, turning sampling time and ending sampling time in the curve data are stored for analysis of the target power fault recording curve. The power data processing method provided in the embodiment of the present application can automatically detect the change in the power data value corresponding to the sampling moment compared with the power data value at the previous sampling moment or the sampling moment after the sampling moment, and can automatically determine the turning sampling moment and the power data value corresponding to the turning sampling moment, and store the determined turning data. When it is necessary to analyze a certain power fault recording curve, there is no need to manually search for these turning data, thereby improving the analysis efficiency of the power data.

[0044] It should be noted that the application test method provided in the embodiment of the present application can be executed by a power data processing device, which can be implemented as part or all of a computer device through software, hardware, or a combination of software and hardware. In the following method embodiments, the execution subject is a server as an example for explanation.

[0045] Optionally, the computer device may be, but is not limited to, various personal computers, laptop computers, and tablet computers, or the computer device may be a server, which may be implemented as an independent server or a server cluster consisting of multiple servers.

[0046] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0047] Please refer to Figure 1 , which shows a flow chart of a method for processing power data provided by an embodiment of the present application, and the method for processing power data can be applied to the computer device mentioned above. Figure 1 As shown, the method for processing power data may include the following steps:

[0048] Step 101: Obtain curve data corresponding to a target power fault recording curve.

[0049] The curve data includes power data values ​​measured at multiple sampling moments, and the curve data is used to fit the target power fault recording curve.

[0050] Among them, the power fault recording records the waveform records formed by the changes of multiple variables in the transient process of the power system over time, and requires a common format for the transient data exchange of the power system to be stored. In this storage format, a set of files can store multiple recording curves, and the file consists of a cfg file and a dat file with the same main file name, among which the cfg file is used to describe the basic information such as the recording curve name, switch quantity / analog quantity, unit, etc., and the dat file is used to store curve data, among which the curve data includes the actual sampling points of the recording and the power data values ​​corresponding to the sampling points.

[0051] Step 102: for each sampling moment in the curve data, based on the target detection strategy, detect the change of the power data value corresponding to the sampling moment compared with the power data value corresponding to the target sampling moment.

[0052] Among them, the target sampling moment is the adjacent sampling moment of the sampling moment, that is, for each sampling moment in the curve data, based on the target detection strategy, the change of the power data value corresponding to the sampling moment compared with the previous sampling moment and / or the next sampling moment is detected.

[0053] Step 103: According to the change of the power data value corresponding to each sampling time, determine the turning sampling time and the power data value corresponding to the turning sampling time from the curve data.

[0054] Among them, the turning sampling moment and the power data value corresponding to the turning sampling moment are key data for analyzing the power fault recording curve.

[0055] By comparing the detected power data value corresponding to the sampling moment with the power data value corresponding to the target sampling moment, the turning sampling moment in the curve data and the power data value corresponding to the turning sampling moment can be determined from the curve data.

[0056] Step 104: Store the starting sampling time, the turning sampling time, the ending sampling time in the curve data, and the power data values ​​corresponding to the starting sampling time, the turning sampling time, and the ending sampling time.

[0057] The starting sampling time, turning sampling time, ending sampling time, and the power data values ​​corresponding to the starting sampling time, turning sampling time, and ending sampling time in the curve data are stored to facilitate the analysis of the target power fault recording curve based on these stored turning data next time.

[0058] The power data processing method provided in the embodiment of the present application obtains curve data corresponding to the target power fault recording curve, and the curve data includes power data values ​​measured at multiple sampling moments, which are used to fit the target power fault recording curve. Then, for each sampling moment in the curve data, based on the target detection strategy, the change of the power data value corresponding to the sampling moment compared with the power data value corresponding to the target sampling moment is detected. The target sampling moment is the sampling moment before the sampling moment or the sampling moment after the sampling moment. According to the change of the power data value corresponding to each sampling moment, the turning sampling moment and the power data value corresponding to the turning sampling moment are determined from the curve data, and the starting sampling moment, the turning sampling moment, the ending sampling moment, and the power data values ​​corresponding to the starting sampling moment, the turning sampling moment and the ending sampling moment in the curve data are stored for analysis of the target power fault recording curve. The power data processing method provided in the embodiment of the present application can automatically detect the change in the power data value corresponding to the sampling moment compared with the power data value at the previous sampling moment or the sampling moment after the sampling moment, and can automatically determine the turning sampling moment and the power data value corresponding to the turning sampling moment, and store the determined turning data. When it is necessary to analyze a certain power fault recording curve, there is no need to manually search for these turning data, thereby improving the analysis efficiency of the power data.

[0059] In one embodiment, if Figure 2 As shown, the technical process of detecting the change of the power data value corresponding to the sampling time compared with the power data value corresponding to the target sampling time based on the target detection strategy, the process includes the following steps:

[0060] Step 201: Obtain the curve type of the target power fault recording curve.

[0061] The curve types include a switch value type, a broken line type, and a third type other than the switch value type and the broken line type.

[0062] Among them, the switch quantity type is the switch quantity curve in the power fault recording curve, and the power data value of each sampling moment of the switch quantity curve is 0 or 1. The broken line type means that the power fault recording curve is a broken line graph. The third type refers to other curves in the power fault recording curve except the switch quantity type and the broken line type.

[0063] Step 202: Determine the target detection strategy according to the curve type.

[0064] When detecting the change in the power data value corresponding to the sampling moment compared to the power data value corresponding to the target sampling moment, the specific detection strategy is different depending on the curve type. The specific detection strategies for different types are described in detail in the following embodiments.

[0065] This embodiment sets a specific detection strategy according to the curve type when detecting the change of the power data value corresponding to the sampling time compared with the power data value corresponding to the target sampling time, which can improve the detection accuracy and detection efficiency.

[0066] In one embodiment, based on the target detection strategy, detecting the change of the power data value corresponding to the sampling time compared with the power data value corresponding to the target sampling time includes:

[0067] When the curve type is a switch value type, the power data value at the sampling time is compared with the power data value at the previous sampling time.

[0068] According to the changes in the power data values ​​corresponding to each sampling moment, the turning sampling moment and the power data value corresponding to the turning sampling moment are determined from the curve data, including: if the power data value at the sampling moment is different from the power data value at the previous sampling moment, the sampling moment is determined as the turning sampling moment, and the power data value corresponding to the sampling moment is determined as the power data value corresponding to the turning sampling moment.

[0069] Optionally, by comparing the power data value at the sampling moment with the power data value at the previous sampling moment, it is also possible to determine whether the transition sampling moment is shifted upward or downward, that is, from 0 to 1 or from 1 to 0.

[0070] In the actual detection process, when the curve type is a switching quantity type, since the power data value at each sampling moment in the switching quantity curve only includes 0 and 1, it is only necessary to compare whether the power data value at the sampling moment is the same as the power data value at the previous sampling moment. If different, the sampling moment is determined as the turning sampling moment, and the power data value corresponding to the sampling moment is determined as the power data value corresponding to the turning sampling moment.

[0071] In one of the embodiments, based on the target detection strategy, the change of the power data value corresponding to the sampling moment compared with the power data value corresponding to the target sampling moment is detected, including: when the curve type is a broken line type or a third type, the power data value at the sampling moment is compared with the power data value at the previous sampling moment and the power data value at the next sampling moment.

[0072] According to the change of the power data value corresponding to each sampling moment, the turning sampling moment and the power data value corresponding to the turning sampling moment are determined from the curve data, including: if the power data value at the previous sampling moment and the power data value at the next sampling moment are both greater than or less than the power data value at the sampling moment, then the sampling moment is determined as the turning sampling moment, and the power data value corresponding to the sampling moment is determined as the power data value corresponding to the turning sampling moment.

[0073] In the actual detection process, except for other power fault recording curves of switch type, the change of the power data value corresponding to the detection sampling moment compared with the power data value corresponding to the target sampling moment is to compare the power data value at the sampling moment with the power data value at the previous sampling moment and the power data value at the next sampling moment. If the power data value at the previous sampling moment and the power data value at the next sampling moment are both greater than or less than the power data value at the sampling moment, the sampling moment is determined as the turning sampling moment, and the power data value corresponding to the sampling moment is determined as the power data value corresponding to the turning sampling moment.

[0074] In one embodiment, the target power fault recording curve includes simulation information and curve data, the simulation information is stored in a first file, and the curve data is stored in a second file, and the starting sampling time, turning sampling time, ending sampling time, and the power data values ​​corresponding to the starting sampling time, turning sampling time, and ending sampling time in the curve data are stored, including: when the curve type is a switch type or a broken line type, creating a target file, storing the starting sampling time, turning sampling time, ending sampling time, and the power data values ​​corresponding to the starting sampling time, turning sampling time, and ending sampling time in the target file, and deleting the second file.

[0075] Among them, the first file is the cfg file mentioned above, and the simulation information includes: basic information such as the name of the recording curve, switch quantity / analog quantity, unit, etc. The second file is the dat file mentioned above, which is used to store curve data, including the sampling time and the power data value corresponding to the sampling time.

[0076] In the case where the curve type is a switch type or a broken line type, by creating a target file, the starting sampling time, the turning sampling time, the ending sampling time, and the power data values ​​corresponding to the starting sampling time, the turning sampling time, and the ending sampling time are stored in the target file, and the second file is deleted. Since the target fault recording curve can be generated by storing the starting sampling time, the turning sampling time, the ending sampling time, and the power data values ​​corresponding to the starting sampling time, the turning sampling time, and the ending sampling time in the case where the curve type is a switch type or a broken line type, the original curve data can be deleted. In this way, the original thousands or even hundreds of thousands of original data points of each recording curve are simplified to several to hundreds of key point information, which significantly reduces memory usage.

[0077] In one embodiment, the target power fault recording curve includes simulation information and curve data, the simulation information is stored in a first file, the curve data is stored in a second file, and the starting sampling time, turning sampling time, ending sampling time, and the power data values ​​corresponding to the starting sampling time, turning sampling time, and ending sampling time in the curve data are stored, including: when the curve type is the third type, creating a target file, storing the starting sampling time, turning sampling time, ending sampling time, and the power data values ​​corresponding to the starting sampling time, turning sampling time, and ending sampling time in the target file, and storing the target file in the first file.

[0078] In practice, for types other than switch type and turning type, the starting sampling time, turning sampling time, ending sampling time, and the power data values ​​corresponding to the starting sampling time, turning sampling time and ending sampling time in the curve data can be stored in the first file, so as to analyze the target power fault recording curve according to the stored turning sampling time and the power data values ​​corresponding to the turning sampling time.

[0079] In one of the embodiments, after storing the starting sampling moment, turning sampling moment, ending sampling moment, and the power data values ​​corresponding to the starting sampling moment, turning sampling moment, and ending sampling moment in the curve data, the method further includes: when the curve type is a switch type or a broken line type, in a preset coordinate system, generating the power data value at the starting sampling moment, the power data value at the turning sampling moment, and the power data value at the ending sampling moment, and generating a target power fault recording curve based on the changes in the power data values ​​corresponding to each sampling moment.

[0080] When the curve type is a switch type, generating a target fault recording curve according to the power data value at the start sampling time, the power data value at the turning sampling time, and the power data value at the end sampling time includes:

[0081] In a preset coordinate system, the starting data point, turning data point and ending data point are generated according to the starting sampling time and the power data value at the starting sampling time, the turning sampling time and the power data value at the turning sampling time, and the ending sampling time and the power data value at the ending sampling time, respectively. And according to whether the turning data point is shifted upward or downward, the starting data point, each turning data point and the ending data point are connected to generate the target fault recording curve. Since thousands or even hundreds of thousands of original data points of each fault recording curve are simplified to several to hundreds of key point information, the target fault recording curve can be generated according to the simplified hundreds of key point information to improve the generation efficiency of the target fault recording curve.

[0082] In one embodiment, a method for processing power data is also provided. Figure 3 As shown, the processing method includes the following steps:

[0083] Step 301: Obtain the curve type of the target power fault recording curve.

[0084] Step 302: Determine the target detection strategy according to the curve type.

[0085] Step 303: Obtain curve data corresponding to the target power fault recording curve.

[0086] Step 304: for each sampling moment in the curve data, when the curve type is a switch value type, compare the power data value at the sampling moment with the power data value at the previous sampling moment.

[0087] Step 305: If the power data value at the sampling moment is different from the power data value at the previous sampling moment, the sampling moment is determined as the turning sampling moment, and the power data value corresponding to the sampling moment is determined as the power data value corresponding to the turning sampling moment.

[0088] Step 306: for each sampling moment in the curve data, when the curve type is a broken line type or the third type, respectively compare the power data value at the sampling moment with the power data value at the previous sampling moment and with the power data value at the next sampling moment.

[0089] Step 307: If the power data value at the previous sampling moment and the power data value at the next sampling moment are both greater than or less than the power data value at the sampling moment, the sampling moment is determined as the turning sampling moment, and the power data value corresponding to the sampling moment is determined as the power data value corresponding to the turning sampling moment.

[0090] Step 308: When the curve type is a switch type or a broken line type, create a target file, store the start sampling time, the turning sampling time, the end sampling time, and the power data values ​​corresponding to the start sampling time, the turning sampling time and the end sampling time in the target file, and delete the second file.

[0091] Step 309: When the curve type is the third type, create a target file, store the start sampling time, the turning sampling time, the end sampling time, and the power data values ​​corresponding to the start sampling time, the turning sampling time and the end sampling time in the target file, and store the target file in the first file.

[0092] Step 310: When the curve type is a switch type or a broken line type, in a preset coordinate system, generate the power data value at the start sampling time, the power data value at the turning sampling time, and the power data value at the end sampling time, and generate the target power fault recording curve according to the change of the power data value corresponding to each sampling time.

[0093] The embodiments of the present application provide a power data processing method, apparatus, equipment and storage medium. In the power data processing method, curve data corresponding to a target power fault recording curve is obtained, and the curve data includes power data values ​​measured at multiple sampling moments, which are used to fit the target power fault recording curve. Then, for each sampling moment in the curve data, based on a target detection strategy, a change in the power data value corresponding to the sampling moment compared with the power data value corresponding to the target sampling moment is detected. The target sampling moment is a sampling moment before the sampling moment or a sampling moment after the sampling moment. According to the change in the power data values ​​corresponding to each sampling moment, a turning sampling moment and a power data value corresponding to the turning sampling moment are determined from the curve data, and the starting sampling moment, the turning sampling moment, the ending sampling moment, and the power data values ​​corresponding to the starting sampling moment, the turning sampling moment and the ending sampling moment in the curve data are stored for analysis of the target power fault recording curve. The power data processing method provided in the embodiment of the present application can automatically detect the change in the power data value corresponding to the sampling moment compared with the power data value at the previous sampling moment or the sampling moment after the sampling moment, and can automatically determine the turning sampling moment and the power data value corresponding to the turning sampling moment, and store the determined turning data. When it is necessary to analyze a certain power fault recording curve, there is no need to manually search for these turning data, thereby improving the analysis efficiency of the power data.
