Description

Technical Field

[0001] The present invention relates to the technical field of power data analysis, and more specifically to a method, system, device and medium for intelligent analysis of substation monitoring information. Background Art

[0002] With the rapid development of social economy, the demand for electricity is growing day by day. As the key node of the power system, the number of substations is also increasing year by year. At the same time, as the core of substation operation monitoring, the number of signals that need to be monitored by the centralized control system of the substation has also increased accordingly. Under the influence of severe weather or other natural disasters, the amount of signals in the substation centralized control station often reaches an alarming scale, and these signals are usually uploaded to the monitoring system in chronological order.

[0003] However, this traditional signal uploading and monitoring method has exposed many problems in practical applications. First, due to the wide range of signal sources, signals from different sites and at different intervals are mixed with each other during the uploading process, resulting in a chaotic monitoring interface, which seriously affects the monitoring ability and signal analysis efficiency of the monitoring personnel. This not only increases the workload of the monitoring personnel, but also reduces their response speed to emergencies.

[0004] Secondly, monitoring personnel (operation and maintenance personnel) are usually only users of the equipment rather than professional maintenance personnel. They are only familiar with the equipment and are mainly limited to basic operation. When the equipment fails, due to the limitation of technical level, monitoring personnel are often unable to accurately determine the specific location of the fault and can only judge the current status of the equipment based on the signal. This not only brings inconvenience to the maintenance personnel, increases their troubleshooting and repair time, but also reduces the emergency response efficiency of the entire power system. Summary of the invention

[0052] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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 work are within the scope of protection of the present invention.

[0053] See also Figure 1 As shown, this embodiment provides a method for intelligent analysis of substation monitoring information, including the following steps:

[0054] S1: Collect the status data of primary and secondary devices in the station, parse the status data, and generate status information.

[0055] In a specific implementation, the status data of the primary and secondary devices in the station are first collected according to the preset unified data; then the status information is parsed, and multiple status information is generated according to the format of the status information. Each status information records: information reporting time, substation voltage level, substation name, equipment voltage level, equipment name, equipment number and status information elements.

[0056] As an example, the status data of primary and secondary equipment in the substation are collected through the automation equipment in the substation. The structure and elements of the status data are standardized and unified. After the collection is completed, it is transmitted to the substation control system through the dispatching data network. By connecting to the substation control system, the data is parsed to form status information one by one. The status information includes information reporting time, substation voltage level, substation name, equipment voltage level, equipment name, equipment number, and status information elements.

[0057] S2: In response to receiving the status information, start information collection; after the status information collection is completed, perform data collection processing on the status information according to different primary devices.

[0058] In a specific implementation, after receiving the first status information, the information collection process is started; after receiving any status information, if no status information is received within a preset time, the information collection process is terminated. After the status information is collected, according to the content of each status information record, the status information is firstly aggregated according to the substation name; then the status information is aggregated again according to the primary equipment name and equipment number; finally, the status is sorted according to the information reporting time in the status information.

[0059] As an example, this step implements a monitoring information collection process to achieve data collection processing. Figure 2As shown in the figure, information collection is started after receiving a certain status information, and ends after a certain delay after receiving the last status information (generally, after an accident occurs, including the time of reclosing, all information can be collected within 30 seconds). After the status information is collected, the key elements of the status information are classified in sequence. First, the information is collected according to the substation name, and then the information is collected according to the name and number of the primary equipment. In this way, all fault information of a certain primary equipment in this time period can be collected, and sorted according to the time in the status information, so as to prepare data for the next step of information analysis.

[0060] S3: Retrieve status information according to preset status information elements, and generate accident report information based on the retrieval results.

[0061] In a specific implementation, the preset status information elements include protection action information, reclosing action information, switch opening information, and switch closing information. This step searches for status information according to any one or any combination of preset status information elements, and generates accident report information based on the search results. The accident report information records: information reporting time, substation name, equipment name, and status information elements.

[0062] As an example, this step implements a monitoring information analysis process, such as Figure 3 As shown, firstly, the status information elements of the collected monitoring information are retrieved, such as protection action information, reclosing action information, switch opening information, switch closing information, etc., and the accident report information is generated through the analysis of these information, such as "XX:XX:XX, XX primary equipment of XX substation + protection action information + accident opening, reclosing action + equipment closing / opening" .

[0063] S4: extracting key fault elements from the accident report information, searching in a preset equipment fault location database based on the key fault elements, and obtaining corresponding faulty equipment information if the corresponding key fault elements can be retrieved.

[0064] The preset equipment fault location database includes: key fault elements and fault information associated with each key fault element; the fault information associated with the key elements includes abnormal consequences and predicted abnormal causes.

[0065] As an example, this step implements a device fault location process based on monitoring information, such as Figure 4As shown in the figure, we must first establish an equipment fault location database. When locating equipment faults, we first correspond the key elements of various types of monitoring information to the corresponding equipment faults, then search the state information elements of the collected monitoring information, identify the key elements, and compare them with the equipment fault location database to find the corresponding equipment fault information and push the fault information to the system front end for reference by the monitoring personnel.

[0066] S5: Based on the primary equipment in the accident report information, retrieve the load information and line contact information related to the primary equipment in the substation centralized control system, and generate a line contact plan according to the load information and line contact information.

[0067] In a specific implementation, first determine the name of the relevant primary equipment based on the substation name and equipment name in the accident report information; then query the relevant load information and line contact information in the substation centralized control system based on the primary equipment name; at this time, generate a contact line of the primary equipment based on the load information and line contact information, and judge whether the link line can bear the contact load of the primary equipment. If so, use the contact line as the link contact plan; if not, replace the contact line of the primary equipment, and continue to judge until a link contact plan is generated.

[0068] As an example, this step implements a monitoring information emergency plan auxiliary formulation process, such as Figure 5 As shown, on the basis of information collection, the load information and line contact information related to the primary equipment of the substation centralized control system are retrieved, and according to the load size, a suitable contact plan is provided to the dispatcher to assist the dispatcher in handling equipment failure tripping, improve the efficiency of accident handling, and restore power supply in time.

[0069] Based on the above-mentioned intelligent analysis method for substation monitoring information, the present invention also discloses an intelligent analysis method for substation monitoring information, taking the 10kV switch interval tripping as an example, by collecting and analyzing the signal, and assisting in the formulation of an emergency plan. Taking the 220kV line interval signal as an example, this method immediately analyzes the cause of the equipment failure and the possible consequences according to the specific information of the signal, and lists them in order according to the probability of the cause, for reference by monitoring personnel and dispatching personnel on duty, providing a basis for the maintenance personnel to prepare tools and spare parts, and improving the efficiency of equipment abnormality handling.

[0070] The specific steps of this method are as follows:

[0071] Step 1: Obtain the monitoring information uploaded daily. As shown in Table 1, the signals from different stations and different intervals are mixed with each other, and the number is huge, which seriously affects the monitoring ability and signal analysis efficiency of the monitoring personnel.

[0072] Table 1: Monitoring information record table

[0073]

[0074]

[0075] Step 2: Taking the 10kV switch interval trip signal as an example, first automatically collect this signal (in a certain period of time, generally when a trip accident occurs, the interval signal duration is less than 30 seconds and all uploads can be completed) and place it in a signal collection table similar to the format shown in Table 2 below. Through the collection of signals, the monitoring personnel can see the signal of a certain interval at a glance, and can quickly identify the substation where the accident occurred, the equipment name, time, whether the overlap is successful, and whether there is any impact on power supply. The signal analysis efficiency of the monitoring personnel is significantly improved.

[0076] Table 2: Signal collection table

[0077]

[0078] Step 3: After the monitoring information is collected, the following analysis results can be obtained through automatic analysis of the signal, as shown in Table 3. Through the analysis results, the monitoring personnel can save the time of analyzing the signal by themselves and report to the dispatcher immediately, thereby improving the emergency handling efficiency of the dispatcher.

[0079] Table 3: Monitoring information analysis results

[0080]

[0081]

[0082] Step 4: After the monitoring information is collected, the cause of the equipment failure is immediately analyzed based on the specific information of the signal. Taking the 220kV line interval signal as an example, as shown in Table 4 below, through abnormal signal analysis, the cause of the abnormal signal and the possible consequences can be immediately analyzed, and listed in order of probability of the cause, for reference by monitoring personnel and dispatching personnel on duty, providing a basis for maintenance personnel to prepare tools and spare parts, and improving the efficiency of equipment abnormality handling.

[0083] Table 4: 220kV line bay fault signal analysis and positioning table

[0084]

[0085]

[0086] Step 5: Taking the tripping of a 10kV line as an example, as shown in Table 5 below, after the monitoring system determines that a certain 10kV line interval has tripped, it will identify the fault location, isolate the faulty line, and immediately provide emergency treatment measures based on the current operating mode and load conditions, such as providing other handle lines for the 10kV line.

[0088]

[0089] It can be seen that the present invention provides an intelligent analysis method for substation monitoring information, which can collect centralized control system information in real time, identify the key content of the information, realize information summarization of the same event, and perform analysis and judgment based on the information summarization. It can effectively improve the accident analysis efficiency of monitoring personnel, accurately locate the fault position of primary and secondary equipment in the substation, and provide a reference for substation operation and maintenance personnel to eliminate equipment failures. At the same time, it can provide auxiliary decision-making basis for dispatching personnel to handle accidents.
