Description

Technical Field

[0001] The present invention belongs to the technical field of distribution network duty log management, and in particular relates to a duty log closed-loop management system based on distribution network control OMS. Background Art

[0002] At present, the dispatching, operation and control management of power distribution lines in Shandong Province relies on the unified Shandong Power Grid Dispatching Management Application System, referred to as the OMS system. The functions of each module of the OMS system cover all aspects of distribution network control work. Among them, the dispatching duty platform is one of the main functional modules used in distribution network control and operation. Its function is to record the daily work of distribution network control in a timely and comprehensive manner and form a work log, which enables the dispatcher to fully and clearly grasp the actual status of the current distribution lines under his jurisdiction. It is an important basis for ensuring that the dispatching duty officer can correctly handle daily control work.

[0003] Due to the huge number of distribution lines within the jurisdiction, the daily workload of distribution network dispatching, control and management is very large, which is mainly reflected in the distribution network fault handling and temporary adjustment of distribution lines and equipment operation modes. The distribution network fault handling includes distribution line tripping handling, abnormality and defect handling, and grounding fault handling. Each fault type and temporary line operation mode adjustment has a corresponding log record type on the OMS system duty platform.

[0004] The handling of distribution network faults and the adjustment of the method are all implemented in a closed-loop management, which is reflected in the log record as log creation and log termination. As shown in the figure below, the fault handling is completed, and the "Terminated" box is checked in the record, indicating that the log is terminated and archived.

[0005] However, there are many factors that affect the timely closure of the distribution network control duty log. First, equipment failures cannot be handled immediately. For example, cable failures may require breaking the road surface for processing, which requires application to the relevant competent authorities, which takes a long time; another example is the failure of the capacitor body in the station. There are no spare parts, which need to be ordered and transported from the manufacturer, which may take months. Second, the line management unit did not report the cause of the line tripping failure in time, resulting in incomplete log records. In addition to human factors, the failure of the user's property equipment requires the user to cooperate in finding the fault. The user needs to find a test team with relevant qualifications to confirm the cause of the fault, which may take several days). Third, the time span of some mode adjustments is large. For example, during the peak summer period, it may be necessary to adjust the operation mode of some lines until the end of summer, which spans about a month. Fourth, when the duty work is busy, it may not be possible to record the duty log in detail, and there are omissions. Although the operation closure has actually been completed, it has not been recorded in the work log in time, resulting in the inability to end the record.

[0006] The duty logs of distribution network control are not closed in time, which lasts for a long time, affecting the dispatcher's actual control over the distribution network, which is not conducive to improving the management level of distribution network dispatching and cannot truly achieve lean dispatching. Due to the large number of distribution lines and equipment under the jurisdiction of the team, the cumulative number of duty logs that have not been closed in time has reached three digits. If they rely on manual verification and regular sorting one by one, the workload is huge. Summary of the invention

[0007] The technical problem to be solved by the present invention is: to overcome the shortcomings of the prior art and provide a duty log closed-loop management system based on the distribution network control OMS. The present invention can realize the organization and early warning of duty logs, reduce the workload of dispatchers, promote timely closure of dispatch logs, and help to improve the dispatch duty work.

[0008] The technical solution adopted by the present invention to solve the problems existing in the prior art is:

[0009] A duty log closed-loop management system based on the distribution network control OMS is characterized in that it includes a management system and an OMS system, and the management system includes an information connection module, a classification module, an early warning module, and a notification module;

[0010] The specific steps are:

[0011] S1. Import the duty log information in the OMS system into the management system;

[0012] S2. Extract and identify the duty log, screen the unfinished records, import the relevant information for secondary classification and screening, and process the unfinished records into three categories: tripping problems, abnormalities and defects, and temporary operation mode adjustment problems;

[0013] S3. Extract relevant characteristic information points from the logs of tripping problems, abnormal and defect problems, and temporary operation mode adjustment problems, generate a summary problem report, and generate a time record entry system for time monitoring and early warning;

[0014] S4. Send the problem summary report to the relevant person in charge.

[0015] Preferably, the management system receives information through the OMS connection module in the information connection module, specifically, is connected to the OMS system through the power grid topology structure.

[0016] Preferably, the screening of unterminated records specifically includes matching keywords with a QMS algorithm to search for end time and fault cause information. If the end time and fault cause information are empty, the data information is secondary classified.

[0017] Preferably, the secondary classification is specifically to extract the event type using the KMP algorithm, and to divide the data into three categories: tripping problems, abnormality and defect problems, and temporary operation mode adjustment problems according to the specific information registered for the event type.

[0018] The tripping problem class extracts the occurrence time, end time, fault cause, processing record and subsequent processing process information through the KMP algorithm, extracts the empty information items, and generates a problem report;

[0019] The abnormal and defect problem class uses the KMP algorithm to extract the occurrence time, end time and subsequent processing process information, and uses the N-1 algorithm to analyze the subsequent processing process information to obtain key information, find the power transmission operation content, and generate a problem report for the situation where there is no end time information and no subsequent processing process information and no power transmission operation;

[0020] The temporary operation mode adjustment problem class extracts the occurrence time, subsequent processing process and content through the KMP algorithm and analyzes it through the N-1 algorithm to extract key information, import the line information of the information connection module, compare the original line and the processed line information, and generate a problem report if there are differences between the original line and the processed line.

[0021] Preferably, the notification module sends the problem report to the master control personnel port after processing all log information.

[0022] Preferably, the early warning information module specifically records the occurrence time of tripping problems, abnormalities and defects, and temporary operating mode adjustment issues, and compares them with the processing limit time set in the background. When the time reaches the processing limit time and is close to the threshold, the problem report is sent to the general control personnel port again and a warning mark is made.

[0023] Preferably, the information connection module includes an OMS connection module and an information storage module, and the information storage includes all log information and distribution line information.

[0024] Compared with the prior art, the present invention has the following beneficial effects: the present invention can quickly find out the unfinished logs by exporting the OMS system log report, form a closed-loop management of the duty log, and can perform time monitoring, and timely issue early warnings for work logs approaching the deadline for resolution, thereby reducing the workload of dispatchers and helping to improve the coordination of duty work. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] Figure 1 This is a flow chart of the closed-loop management system of the duty log based on the distribution network control OMS of the present invention.

[0027] Figure 2 This is a structural diagram of the duty log closed-loop management system based on the distribution network control OMS of the present invention. DETAILED DESCRIPTION

[0028] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0029] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] An embodiment of a duty log closed-loop management system based on the distribution network control OMS of the present invention is further described in detail below with reference to the accompanying drawings, but it is not intended to limit the present invention.

[0031] The specific operation steps of the duty log closed-loop management system based on the distribution network control OMS are as follows:

[0032] S1. Import the duty log information in the OMS system into the management system;

[0033] S2. Extract and identify the duty log, screen the unfinished records, import the relevant information for secondary classification and screening, and process the unfinished records into three categories: tripping problems, abnormalities and defects, and temporary operation mode adjustment problems;

[0034] S3. Extract relevant characteristic information points from the logs of tripping problems, abnormal and defect problems, and temporary operation mode adjustment problems, generate a summary problem report, and generate a time record entry system for time monitoring and early warning;

[0035] S4. Send the problem summary report to the relevant person in charge.

[0036] The duty log closed-loop management system based on the distribution network control OMS includes a management system and an OMS system. The management system includes an information connection module, a classification module, an early warning module and a notification module.

[0037] The information connection module is further divided into the OMS connection module and the information storage module. The OMS connection module is connected to the OMS system through the power grid topology structure to realize the information interaction between the management system and the OMS system. The information storage module is divided into two parts, one part is all the log information and other contents imported through the OMS system, and the other part is the information input from the outside, such as distribution line information, on-duty personnel information, distribution system management details, etc. While realizing the functions of this embodiment, sufficient excuses are reserved to facilitate subsequent functional expansion.

[0038] The specific function of the classification module is to classify the duty information twice. The first classification is to classify and sort the completed and unfinished parts of the duty information. The specific steps are to use the QMS algorithm to match the keywords, find the end time and fault cause information, and the end time and fault cause information are empty, which is an unfinished duty log. The unfinished duty data information is classified twice, and the KMP algorithm is used to extract the event type. According to the specific information registered by the event type, the data is divided into three categories: tripping problems, abnormalities and defects, and temporary operation mode adjustment problems.

[0039] For the above three types of problems, the corresponding feature points are extracted for information reading, specifically:

[0040] The tripping problem class extracts the occurrence time, end time, fault cause, processing record and subsequent processing process information through the KMP algorithm. If there is blank information in the end time, fault cause, processing record or subsequent processing process information, the blank information features are extracted to generate a problem report.

[0041] The abnormal and defect problem class uses the KMP algorithm to extract the occurrence time, end time and subsequent processing process information, and uses the N-1 algorithm to analyze the subsequent processing process information to obtain key information and find the power supply operation content. If the end time information is blank or there is no power supply operation in the subsequent processing process information, a problem report is generated.

[0042] The temporary operation mode adjustment problem class extracts the occurrence time, subsequent processing process and content through the KMP algorithm and analyzes it through the N-1 algorithm to extract key information, import the line information of the information connection module, compare the original line and the processed line information, and generate a problem report if there is a difference between the original line and the processed line.

[0043] After the notification module completes processing of all log information, it sends the problem report to the master control personnel port. After receiving the problem report, the master control personnel will feedback the unfinished duty log to the relevant responsible department to urge the duty log to be completed as soon as possible, which simplifies the work content of the master control personnel, improves their work efficiency, and makes the pending matters clearer.

[0044] The present invention is also provided with an early warning module, which specifically records the occurrence time of tripping problems, abnormal and defect problems, and temporary operation mode adjustment questions, and compares them with the processing limit time set by the background. When the time reaches the processing limit time close to the threshold, the problem report is sent to the master control personnel port again and an early warning mark is made. It can ensure that the unfinished logs can be completed within the expected time, avoiding the unfinished logs being forgotten and the work being unfinished.

[0045] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
