[0002] With the rapid development of power system automation technology, as an important link of power transmission and distribution, the automation degree of substations is continuously improved. Substation automation equipment (such as relay protection devices, automatic switch equipment, monitoring systems, etc.) plays an important role in ensuring the safe and stable operation of the power system. However, due to the complex operating environment of substation equipment, the equipment is in a high-voltage and heavy-load working state for a long time, and the health status of these automation equipment directly affects the safety and reliability of the power system.

[0003] At present, the health monitoring and evaluation of substation automation equipment mainly relies on traditional equipment state monitoring methods. For example, the existing system mostly adopts real-time monitoring method of single physical quantity (such as temperature, current, voltage, etc.). Although the abnormal state of the equipment can be detected, most of these monitoring methods can only reflect the local health status of the equipment, and it is difficult to comprehensively evaluate the overall health level of the equipment. Moreover, the health evaluation of many substation equipment relies on manual inspection and regular maintenance. Although this method can find some obvious fault problems, due to the time interval of inspection and the limitation of manual judgment, potential equipment failure problems are easily missed, and real-time monitoring and prediction cannot be achieved. In summary, the existing health monitoring and evaluation method of substation automation equipment has certain limitations, and cannot effectively solve the problems of comprehensive evaluation and real-time warning of equipment state.

[0004] Therefore, an intelligent system integrating multi-dimensional monitoring parameters is urgently needed, which can comprehensively evaluate the health status of the equipment, and then assist in formulating real-time and accurate operation and maintenance strategies for substation automation equipment.

[0039] In this embodiment, the acquisition module 102 includes a data integration unit and a data management unit.

[0040] The data integration unit is configured to automatically synchronize the secondary index data corresponding to the basic information evaluation indexes, the operation state evaluation indexes, the operation risk evaluation indexes, and the operation and maintenance support evaluation indexes of the substation automation equipment from a multi-source system, wherein the multi-source system is a system related to the data of the substation automation equipment.

[0041] The data management unit is configured to integrate and process the secondary index data corresponding to the basic information evaluation indexes, the operation state evaluation indexes, the operation risk evaluation indexes, and the operation and maintenance support evaluation indexes to form a standard specification data table.

[0042] In this embodiment, the data processing module 103 includes a device basic information evaluation unit, an operation state evaluation unit, an operation risk evaluation unit, and an operation and maintenance support evaluation unit.

[0043] The device basic information evaluation unit is configured to monitor the data of the account information, the model information, and the configuration information in real time, and then analyze the account accuracy, the model compliance, and the configuration rationality to determine the state quantity of the account information, the model information, and the configuration information.

[0044] The operation state evaluation unit is configured to monitor the data of the self-checking alarm information, the self-checking measurement information, the remote control operation information, and the operation parameter information in real time, and then analyze the self-checking alarm frequency, the value out-of-limit frequency, the remote control operation success rate, and the operation parameter accuracy to determine the state quantity of the self-checking alarm information, the self-checking measurement information, the remote control operation information, and the operation parameter information.

[0045] The operation risk evaluation unit is configured to monitor data of the operation life information and the defect information in real time, to calculate an operation life coefficient of the substation automation equipment, and to analyze family defects and non-family defects existing in the substation automation equipment, so as to determine state values of the operation life information and the defect information.

[0046] The operation and maintenance support evaluation unit is configured to monitor data of the version management information, the operation and maintenance information, and the technical service information in real time, to analyze whether the software version and the over-inspection version of the substation automation equipment are consistent, and to analyze the compliance of the operation and maintenance information and the rationality of the technical service information, so as to determine state values of the version management information, the operation and maintenance information, and the technical service information.

[0047] Specifically, for the equipment basic information evaluation unit, it can be understood that an initial state value (for example, 25 points) of the account information is set in advance, the account information is monitored in real time, the accuracy and completeness of the account information are determined, and if the account information is incorrect or incomplete, one point is deducted for each item, and then the state value corresponding to the account information is determined; an initial state value (for example, 15 points) of the model information is set in advance, the model information is monitored in real time, the Schema syntax, consistency, repeated definition, and standardization of the model information are checked, and if there is a problem in the Schema syntax, consistency, repeated definition, or standardization, points are deducted respectively, and then the state value corresponding to the model information is determined; an initial state value (for example, 60 points) of the configuration information is set in advance, the configuration information is monitored in real time, and if the configuration of the operating system, the database, the application software function, or the hardware module does not meet the current equipment operation requirement, points are deducted for each item found, and then the state value of the configuration information is determined.

[0048] In addition, it should be noted that the account information specifically refers to equipment basic account and asset information, including physical ID, asset number, manufacturer, equipment name, equipment model, software version, detection agency, and report number information; the model information includes substation SCD, ICD, CID, SPCD, SPD, CCD, RCD, and other model file version numbers, model contents, and verification results; and the configuration information includes operating system, application software function, hardware module, database, and other information, which slightly differs according to different substation automation equipment, and will not be described in detail here.

[0049] Specifically, for the above running state evaluation unit, the initial state value of the self-checking alarm information (for example, 35 points) can be understood as being set in advance, the self-checking alarm information is monitored in real time, the frequency of device alarms in the preset evaluation period is judged, the preset points are deducted for single alarm, and the points are multiplied or accumulated for multiple alarms, and then the state value corresponding to the self-checking alarm information is determined; the initial state value of the self-checking measurement information (for example, 25 points) is set in advance, the self-checking measurement information is monitored in real time, the frequency of value limit is judged in the preset evaluation period, the preset points are deducted for single value limit, and the points are multiplied or accumulated for multiple value limits, and then the state value corresponding to the self-checking measurement information is determined; the initial state value of the remote control operation information (for example, 25 points) is set in advance, the remote control operation information is monitored in real time, the success rate of remote control operation in the preset evaluation period is judged, the preset points are deducted for single remote measurement failure, and the points are multiplied or accumulated for multiple remote measurement failures, and then the state value corresponding to the remote control operation information is determined; the initial state value of the running parameter information (for example, 15 points) is set in advance, the running parameter information is monitored in real time, the accuracy and integrity of the running parameter information are judged, and 1 point is deducted for each incorrect or incomplete running parameter information, and then the state value corresponding to the running parameter information is determined.

[0050] Specifically, the above running risk evaluation unit can be understood as follows: the initial state value of the running life information (for example, 35 points) is set in advance, then the actual running life B of the substation automation equipment is determined based on the real-time monitored running life information; based on the known recommended running life A of the substation automation equipment and the actual running life B of the substation automation equipment, the running life coefficient C of the substation automation equipment is calculated through the equipment running life calculation formula, and then the running life coefficient C and the initial state value of the running life information are multiplied to determine the state value corresponding to the running life information, wherein the equipment running life calculation formula is:

[0051] The above running risk evaluation unit also sets the initial state value of the defect information (for example, 65 points) in advance, then inputs the real-time monitored defect information into the defect recognition model, and the defect recognition model recognizes the defect type, wherein the defect type includes familial defects and non-familial defects, and the defect recognition model is optimized by historical defect data in advance. Then, the number of existing familial defects and non-familial defects is obtained, a preset point is deducted for single familial defect, and the points are multiplied or accumulated for multiple familial defects, and then the state value corresponding to the defect information is determined.

[0052] Specifically, the operation and maintenance support evaluation unit can be understood as follows: an initial state value (for example, 30 points) of version management information is set in advance, then based on the real-time monitored version management information, the check code of each software program in the substation automation equipment is determined; based on the check code of each software program in the substation automation equipment and the pre-stored reference information of each software program in the substation automation equipment, it is determined whether the software version of the substation automation equipment and the inspection version are consistent, and if consistent, full marks are given, and if inconsistent, no marks are given.

[0053] The operation and maintenance support evaluation unit also sets an initial state value (for example, 40 points) of operation and maintenance information in advance, then real-time operation and maintenance information is used to determine the timeliness of defect handling, maintenance management execution, inspection regulation execution, and commissioning and decommissioning execution within a preset evaluation period, and then determine the state value corresponding to the operation and maintenance information; an initial state value (for example, 40 points) of technical service information is also set in advance, then real-time technical service information is used to determine the equipment on-site operation, ease of use, emergency defect response, after-sales service level, technical support, and system integration capability within a preset evaluation period, and then determine the state value corresponding to the technical service information.

[0054] It should be emphasized that the state value of any secondary index cannot be negative, the minimum is 0, and the maximum does not exceed the initial state value.

[0055] In this embodiment, based on the preset weight corresponding to each secondary index and the state value corresponding to each secondary index, the score corresponding to each primary index is determined. Taking the basic information evaluation index as an example, the initial state values of the account information, model information, and configuration information are preset to be 25, 15, and 60, and the state values obtained by the account information, model information, and configuration information are 15, 12, and 50. At this time, the score corresponding to the basic information evaluation index can be directly considered as the sum of 15, 12, and 50, that is, 77; or the initial state values of the account information, model information, and configuration information are set to 100, 100, and 100, and the corresponding weights are 0.25, 0.15, and 0.60, respectively. The state values obtained by the account information, model information, and configuration information are 60, 80, and 84. The weight corresponding to each secondary index and the state value corresponding to each secondary index are multiplied and accumulated, that is, 77. Similarly, details are not repeated.

[0056] In addition, if there is a secondary index that is not applicable to evaluate the substation automation equipment, the weights of the remaining secondary indexes applicable to evaluate the substation automation equipment are recalculated;

[0057] Based on the re-converted weights of the remaining applicable evaluation substation automation equipment secondary indicators and the state values corresponding to the applicable evaluation substation automation equipment secondary indicators, the score corresponding to each primary indicator is determined.

[0058] Similarly, if there is a primary indicator that is not applicable to evaluate the substation automation equipment, the weights of the remaining applicable evaluation substation automation equipment primary indicators are re-converted;

[0059] Based on the re-converted weights of the remaining applicable evaluation substation automation equipment primary indicators and the scores corresponding to the applicable evaluation substation automation equipment primary indicators, the health degree score of the substation automation equipment is determined.

[0060] In this embodiment, the health degree score adopts an interval system to determine the health state of the substation automation equipment, which is specifically divided into four levels: normal state, attention state, abnormal state, and serious state. Among them, 60 and below is the serious state, 61-70 is the abnormal state, 71-85 is the attention state, and 86-100 is the normal state. Subsequently, different maintenance strategies can be implemented for different states, such as a) when the equipment state evaluation is normal, no maintenance or regular maintenance according to the specified period can be carried out; b) when the equipment state evaluation is attention, the equipment inspection frequency should be increased and the equipment maintenance period should be shortened, and through appearance inspection, online monitoring, etc., the equipment operation state should be closely monitored; c) when the equipment state evaluation is abnormal, component inspection, maintenance and replacement should be carried out to restore it to normal state; d) when the equipment state evaluation is serious, overall replacement, inspection and testing should be carried out.

[0061] In summary, in the embodiments of the present application, an evaluation index system of substation automation equipment including primary indicators and secondary indicators is constructed, and related data is acquired for analysis and processing. Then, based on the pre-set weights corresponding to each primary indicator and each secondary indicator, the health degree score of the substation automation equipment is determined, and the health state of the substation automation equipment is determined. Based on this, the health state of the substation automation equipment can be comprehensively evaluated, and then real-time and accurate substation automation equipment operation and maintenance strategies can be formulated subsequently.

[0065] In step S202, the second-level index data corresponding to the basic information evaluation index, the operation state evaluation index, the operation risk evaluation index and the operation and maintenance support evaluation index are obtained and integrated.

[0066] In step S203, the second-level index data corresponding to the basic information evaluation index, the operation state evaluation index, the operation risk evaluation index and the operation and maintenance support evaluation index are analyzed and processed to determine a state value corresponding to each second-level index.

[0067] In step S204, a score corresponding to each first-level index is determined based on a preset weight corresponding to each second-level index and the state value corresponding to each second-level index, and a health degree score of the substation automation equipment is determined based on a preset weight corresponding to each first-level index and the score corresponding to each first-level index.
