[0056] Figure 2 This is a flow chart of the algorithm for improving the power supply reliability of the distribution network according to the present invention. DETAILED DESCRIPTION

[0057] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0058] In order to solve the problem that the existing distribution network cannot monitor and understand the power supply status of the distribution network in a timely manner during operation, and cannot perform timely intelligent management and control based on the real-time power supply status of the distribution network, resulting in low power supply reliability and poor power supply effect of the distribution network, please refer to Figure 1-Figure 2 , this embodiment provides the following technical solutions:

[0059] A method for improving power supply reliability of a distribution network comprises the following steps:

[0060] S1: Collecting power supply current data, power supply voltage data, and power supply frequency data of the distribution network in operation, and determining real-time power supply data of the distribution network in operation based on the collected power supply current data, power supply voltage data, and power supply frequency data;

[0061] In this embodiment, the power supply current data, power supply voltage data, and power supply frequency data of the power distribution network in operation are collected, and the following operations are performed:

[0062] A current sensor is installed on the running distribution network, and the power supply current data of the distribution network in the running state is obtained based on the current sensor;

[0063] It should be noted that the current sensor is a detection device that can sense the information of the measured current and can convert the sensed information into an electrical signal or other required form of information output that meets certain standard requirements according to a certain rule to meet the requirements of information transmission, processing, storage, display, recording and control. Therefore, the current sensor can be used to collect the power supply current data of the distribution network in operation in real time, which is convenient for subsequent processing and analysis of the power supply current data.

[0064] A voltage sensor is installed on the running distribution network, and the power supply voltage data of the distribution network in the running state is obtained based on the voltage sensor;

[0065] It should be noted that a voltage sensor is a sensor that can sense the measured voltage and convert it into a usable output signal. In various automatic detection and control systems, it is often necessary to track and collect high-speed changing AC and DC voltage signals and perform spectrum analysis on more complex voltage waveforms. Therefore, the voltage sensor can be used to collect the power supply voltage data of the distribution network in real time during operation, which facilitates the subsequent processing and analysis of the power supply voltage data.

[0066] The frequency sensor is installed on the running distribution network, and the power supply frequency data of the distribution network in the running state is obtained based on the frequency sensor.

[0067] It should be noted that frequency sensors generally refer to frequency switching sensors. Frequency switching sensors are instruments that convert input frequency into linearly output DC current and voltage and isolate analog signals. They are input components for analog quantity acquisition required in power systems, remote control, and automation control systems. They can accurately measure various frequencies such as low frequency, industrial frequency, and high frequency. Therefore, frequency sensors can be used to collect power supply frequency data of the distribution network in operation in real time, which facilitates subsequent processing and analysis of the power supply frequency data.

[0068] S2: Acquire real-time power supply data of the distribution network in operation, perform data retrieval, data conversion, feature extraction, and data calculation on the real-time power supply data, and determine the power supply characterization data of the distribution network in operation;

[0069] In this embodiment, data retrieval, data conversion, feature extraction, and data calculation are performed on the real-time power supply data, and the following operations are performed:

[0071] Based on the sequential retrieval method, the real-time power supply data is retrieved one by one;

[0072] Filter out the real-time power supply data that is not valuable for improving the power supply reliability of the distribution network;

[0073] Determine the portion of the real-time power supply data that is valuable for improving the reliability of power supply in the distribution network;

[0074] It should be noted that the real-time power supply data collected when the distribution network is in operation contains duplicate or missing data. For example, the real-time power supply data collected when the distribution network is in operation includes A, B, C, D, and E, where A is duplicate data and B is missing data. Therefore, by searching the real-time power supply data one by one, the duplicate data A and the missing data B in the real-time power supply data A, B, C, D, and E can be filtered out, which can improve the accuracy and efficiency of subsequent data processing.

[0075] Obtain real-time power supply data that is valuable for improving the reliability of distribution network power supply;

[0076] Performing data conversion on the real-time power supply data to standardize the format of the real-time power supply data and determining the real-time power supply data in a standardized format;

[0077] It should be noted that the real-time power supply data after retrieval contains different data formats. Therefore, it is necessary to convert the format of the real-time power supply data to standardize the format of the real-time power supply data to facilitate subsequent processing and analysis of the real-time power supply data.

[0078] Acquire real-time power supply data in a standardized format, extract features from the real-time power supply data, and determine the power supply feature data of the distribution network in operation;

[0079] It should be noted that by extracting the features of the real-time power supply data, the power supply feature data of the distribution network in operation can be determined, which is convenient for the subsequent calculation of the power supply feature data.

[0080] Obtain power supply characteristic data of the distribution network in an operating state, perform data calculation on the power supply characteristic data, and determine the power supply characterization data of the distribution network in an operating state.

[0081] It should be noted that by performing data calculation on the power supply characteristic data, the power supply characterization data of the distribution network in the operating state is determined, which facilitates subsequent analysis of the power supply characterization data.

[0082] S3: Obtain power supply characterization data of the distribution network in operation, perform comparative analysis on the power supply characterization data based on pre-set power supply standard data, and determine a power supply comparative analysis result of the distribution network in operation;

[0083] In this embodiment, based on the pre-set power supply standard data, the power supply characterization data is compared and analyzed, and the following operations are performed:

[0084] Obtain power supply characterization data of the distribution network in operation;

[0085] Based on the power supply characterization data, power supply standard data matching the power supply characterization data is indexed from a plurality of pre-set power supply standard data;

[0086] Obtaining the indexed power supply standard data that matches the power supply characterization data, and retrieving the indexed power supply standard data;

[0087] Based on the pre-set power supply standard data, the power supply characterization data is compared and analyzed to determine the power supply comparison analysis results of the distribution network under the operating state;

[0088] Among them, if the power supply characterization data is within the power supply standard data range, the power supply comparison analysis result of the distribution network in the operating state is that the power supply of the distribution network is in a normal state;

[0089] Among them, if the power supply characterization data is not within the power supply standard data range, the power supply comparison analysis result of the distribution network in the operating state is that the power supply of the distribution network is in an abnormal state.

[0090] It should be noted that when comparing and analyzing the power supply characterization data, the power supply comparison analysis results are shown in Table 1:

[0093] Therefore, based on the pre-set power supply standard data, the power supply characterization data is compared and analyzed to determine the power supply comparison analysis results of the distribution network in operation, which is convenient for the subsequent formulation of the distribution network power supply control method in operation.

[0094] In this embodiment, based on the power supply characterization data, power supply standard data matching the power supply characterization data is indexed from a plurality of pre-set power supply standard data, including:

[0099] In the case where the indexed power supply standard data does not match the power supply real-time data, the indexed power supply standard data is not the power supply standard data used for comparative analysis of the power supply characterization data.

[0101] Continue to index the next power supply standard data in sequence from the pre-set multiple power supply standard data, and compare and analyze the next power supply standard data indexed in sequence with the real-time power supply data until the next power supply standard data indexed in sequence matches the real-time power supply data. The next power supply standard data indexed in sequence is the power supply standard data used for comparison and analysis of the power supply characterization data.
