In one embodiment, referring to fig. 2, fig. 2 is a schematic flow chart of an early warning method of the relay protection device. As shown in fig. 2, the method is applied to a server as an example. An early warning method of a relay protection device comprises the following steps:

step 202, when a defect of an insert of the relay protection device is detected, acquiring a current defect record of the relay protection device, wherein the current defect record comprises a current defect type and current insert information of the insert with the defect in the relay protection device.

The relay protection device is a complete set of equipment for realizing automatic measures, wherein the relay protection device can timely send out warning signals to operating operators on duty or directly send out tripping commands to a controlled breaker to terminate the development of the events when the power elements in the power system such as a generator, a circuit and the like or the power system itself breaks down to endanger the safe operation of the power system. The plug-in units refer to various components constituting the relay protection device, and the monitoring plug-in units are specific objects for monitoring the relay protection device. The plug-in information record is an information base which records the plug-in information of all relay protection devices in operation in real time. The history defect record is an information base which records the defect information of all plug-ins with defects in real time. It is to be easily understood that the present application is not particularly limited in terms of the types of records in the plug-in information record and the history defect record, and may be set according to actual needs. The plug-in information record includes a plurality of plug-in information, and the plug-in information can record information of corresponding plug-ins, and the plug-in information can record: plug-in type (power strip plug-in, plug-in board plug-in, protection board plug-in, AC board plug-in, management board plug-in, communication board plug-in, bus board plug-in, display board plug-in), plug-in batch and model, plug-in software version, plug-in initial use time, plug-in service life time limit, and the like.

Specifically, when at least one plug-in unit in the relay protection device is detected to be defective, a current defect record of the at least one plug-in unit with the defect is obtained, wherein the current defect record comprises a current defect type and current plug-in unit information of the plug-in unit with the defect.

Optionally, in the process of early warning and monitoring the relay protection device, when one of the plug-ins of one of the relay protection devices is monitored to have defects, obtaining information base plug-in information records of the plug-in information of all the relay protection devices in operation in real time, and obtaining information base history defect records of the defect information of all the plug-ins which have the defects in real time.

Step 204, according to the current defect type and the current plug-in information, inquiring a target defect record consistent with the current plug-in information and the current defect type from a historical defect record, wherein the historical defect record comprises the defect type and the plug-in information of the plug-in with the defect in the relay protection device before the current defect.

The defect type refers to the defect type of the plug-in the relay protection device. It is easy to understand that the content of the defect type is not particularly limited, and may be set according to actual needs. Optionally, the defect type of the plug-in the relay protection device is divided into a hardware defect and a software defect, wherein the hardware defect refers to that the plug-in defect is generated in a specific hardware structure of the plug-in the relay protection device, and the software defect refers to that the plug-in defect is generated in a software program of the plug-in the relay protection device. It is easy to understand that when a plug-in a relay protection device is monitored to have a defect, the defect may be one of a hardware defect or a software defect, or may be a defect having both of a hardware defect and a software defect. The plug-in identification refers to proprietary identity information for indicating that a plug-in is different from other plug-ins, and one plug-in corresponds to one plug-in identification. The target plug-in information refers to information content which is located in the plug-in information record and can reflect certain specific information of the plug-in.

Specifically, according to the defect type and the current plug-in information of the plug-in with the defect, a target defect record which is consistent with the current plug-in information and the current defect type is queried from a historical defect record, wherein the historical defect record comprises the defect types and the plug-in information of all plug-ins which have the defect in the relay protection device before the current defect.

Optionally, in the process of early warning and monitoring the relay protection devices, when one of the plug-ins of one of the relay protection devices is monitored to have defects, the computer equipment can determine the type of the defects of the plug-in to obtain the defect type of the plug-in. For example, it may be determined which defect type the card belongs to, a hardware defect, a software defect, and which defect type both a hardware defect and a software defect exist. Further, the computer equipment also determines that the plug-in is different from the exclusive identity information of other plug-ins, namely, the plug-in identification, and when the plug-in identification and the defect type corresponding to the plug-in are determined, information content corresponding to the determined plug-in identification and defect type is searched in the plug-in information record, wherein the information content is the target plug-in information searched from the plug-in information record.

And 206, if the target defect record meets the preset early warning condition, determining a plug-in to be early warned in the relay protection device from a plug-in information record according to the defect type and the plug-in information, wherein the plug-in information record comprises the plug-in information of the relay protection device.

The target defect record is a record of defect information which is consistent with the target plug-in information and appears in the history defect record, and the history defect record can acquire the defect information of each plug-in with defects in real time and store the defect information; the history defect record has a plurality of defect records recorded therein, and the defect records are text recorded with information related to the defect, for example, when the plug-in A has a defect, one defect record can be generated for the defect generated by the plug-in A, and the defect record has at least one of a batch of the plug-in A, a type of the defect generated by the plug-in A at the time and a software version of the plug-in A recorded.

Specifically, when the target defect record meets a preset early warning condition, determining a plug-in to be early warned in the relay protection device from the plug-in information record according to the current defect type and the current plug-in information, wherein the plug-in information record records plug-in information of the current relay protection device.

Optionally, when the number of target defect records is greater than the number of preset defect records, the relay protection device can be considered to monitor the defects of the plug-in unit for multiple times at the historical moment. At this time, an early warning is required for an operation plug-in the relay protection device, in which the defect may occur. Therefore, at the moment, according to the target plug-in information corresponding to the detected plug-in with the defect, the plug-in the relay protection device which corresponds to the target plug-in information and is in the running working state is determined in the plug-in information record and used as the plug-in to be subjected to early warning processing.

The preset defect record number refers to the preset record number of defect information which is found in the history defect record according to the target plug-in information and is found in the plug-in corresponding to the target plug-in information. It is easy to understand that the number of preset defect records is a preset fixed value, and the number of preset defect records in which defect information that has occurred in a plug-in corresponding to the target plug-in information is searched in a history defect record according to the target plug-in information is not specifically limited, and can be set according to actual needs. The number of target defect records refers to the number of defect information records which are actually found in the history defect records according to the target plug-in information and are consistent with the target plug-in information. The operation plug-in to be pre-warned is a plug-in which meets the pre-warning condition and is in an operation working state. The method comprises the steps that the number of target defect records is larger than the number of preset defect records, and the target defect records and target plug-in information are matched.

And step 208, determining an early warning measure based on the defect type, and carrying out early warning treatment on the plug-in to be early warned based on the early warning measure.

The early warning measures are specific measures adopted in early warning processing of operation plug-ins to be early warned in the relay protection device determined according to target plug-in information corresponding to the defective monitoring plug-ins and plug-in information records. It is easy to understand that the pre-warning measures adopted in the pre-warning process are not particularly limited, and can be set according to actual needs. Optionally, in the present application, the early warning measures are determined according to the defect type of the monitoring plug-in, and different defect types correspond to different early warning measures.

Specifically, based on the defect type of the plug-in unit with the defect, the early warning measures are determined, and the plug-in unit which is determined to be subjected to early warning is subjected to early warning treatment according to the determined early warning measures.

Optionally, determining, in the plug-in information record, a plug-in an operating state in the relay protection device corresponding to the target plug-in information according to the target plug-in information corresponding to the detected plug-in with the defect, and taking the plug-in as a plug-in to be subjected to early warning processing. Further, according to the defect type corresponding to the defective monitoring plug-in, determining an early warning measure adopted by the defective monitoring plug-in, and finally, carrying out early warning treatment on the plug-in which is in the running working state in the relay protection device corresponding to the target plug-in information.

In one embodiment, under the condition that the current defect type is a hardware defect, inquiring a hardware defect record consistent with the plug-in type, the plug-in batch and the hardware defect from a historical defect record according to the plug-in type and the plug-in batch in the current plug-in information; and under the condition that the defect type is a software defect, inquiring a software defect record consistent with the software version, the plug-in type and the software defect from a history defect record according to the software version and the plug-in type in the plug-in information.

Firstly distinguishing according to whether the defect type of the monitored plug-in is a hardware defect or a software defect, and inquiring a hardware defect record consistent with the plug-in type, the plug-in batch and the hardware defect from a historical defect record according to the plug-in type and the plug-in batch in the plug-in information of the current time if the defect type of the plug-in with the defect is the hardware defect; if the defect type of the plug-in with the defect at this time is a software defect, inquiring a software defect record consistent with the software version, the plug-in type and the software defect from a history defect record according to the software version and the plug-in type in the plug-in information at this time.

The defect types of the plug-in are specifically divided into hardware defects and software defects, and different plug-in information is determined according to the difference of the hardware defects and the software defects. The monitored defects can be covered not only on the defects of each specific plug-in structure in the relay protection device, but also on the defects of software programs applied by the specific plug-in structures, so that the defect early warning is more comprehensive and finer.

In one embodiment, if the hardware defect record meets a preset early warning condition, determining an insert to be early warned from the insert information record, wherein the insert to be early warned is an insert consistent with the insert type and the insert batch in the insert information; and if the software defect record meets the preset early warning condition under the condition that the defect type is a software defect, determining an insert to be early warned from the insert information record, wherein the insert to be early warned is an insert consistent with the software version and the insert type in the insert information.

Specifically, when the number of the hardware defect records or the software defect records is greater than the number of the preset defect records, the relay protection device can be considered to have the defects of the plug-in unit with the defect at the time of history. At this time, early warning is required for the plug-in unit in the relay protection device, which may have the defect. Therefore, according to the current plug-in information corresponding to the plug-in with the defect, the plug-in the working state in the relay protection device corresponding to the current plug-in information is determined in the plug-in information record and used as the plug-in to be subjected to early warning processing.

Because different searching ranges can be determined according to two different defect types of the hardware defect and the software defect, and further other plug-ins which are in a working state and are consistent with the plug-in with the defect are searched in the plug-in information record, the early warning of the plug-in is more refined.

In one embodiment, in the case that the defect type of the monitoring plug-in is a software defect, the software program to be upgraded is determined based on the plug-in type and the software version of the monitoring plug-in. And under the condition that the upgrading can be supported in the plug-in spare information, upgrading the software program of the plug-in running state consistent with the plug-in type and the software version of the plug-in, and under the condition that the upgrading cannot be supported in the plug-in spare information, performing early warning processing on the plug-in spare.

In one embodiment, under the condition that the current defect type is a hardware defect, determining the number of plug-in spare parts to be replaced in plug-in spare parts information based on the plug-in type and the plug-in batch in the current plug-in information; under the condition that the number of the plug-in spare parts is larger than or equal to that of the plug-in to be pre-warned, replacing the plug-in to be pre-warned with the plug-in spare parts; and under the condition that the number of the plug-in spare parts is smaller than the number of the operation plug-in parts, carrying out early warning processing on the plug-in spare parts.

Specifically, when the defect type of the detected plug-in unit with the defect is a hardware defect, determining a specific plug-in unit type and a specific plug-in unit batch of the detected plug-in unit, determining the number of plug-in unit spare parts meeting the replacement condition in the plug-in unit spare part information and the number of plug-in units in the running working state, when the number of the plug-in unit spare parts meeting the replacement condition in the plug-in unit spare part information is greater than or equal to the number of the plug-in units in the hardware replacement required and the plug-in units in the running working state, replacing the plug-in unit spare parts meeting the replacement condition in the plug-in unit spare part information required and the plug-in units in the running working state, and when the number of the plug-in unit spare parts meeting the replacement condition in the plug-in unit spare part information is smaller than the number of the plug-in units in the plug-in unit spare part required and the hardware replacement required and the plug-in units in the running working state.

Because the plug-in spare parts meeting the replacement condition can be determined from the plug-in spare part information, the plug-in replacement is performed for the plug-in with defect risk in operation, so that the plug-in the relay protection device can be maintained and managed in batches, frequent maintenance and management of single plug-in is avoided, the maintenance and management cost is saved, and the maintenance and management of the relay protection device are more efficient.

In one embodiment, based on the early warning measures, deleting the original information record of the replaced plug-in the plug-in information record, adding the plug-in information of the replaced plug-in spare part into the plug-in information record, and finally realizing the coverage of the plug-in information.

Specifically, according to defect measures taken on the monitoring plug-in units with defects, the service lives of the replaced plug-in units originally recorded in the plug-in unit information records are updated to obtain new plug-in unit information records, and early warning and monitoring of the plug-in units in the relay protection device are continued according to the new plug-in unit information records.

Because the life cycle of the plug-in is changed after the early warning measures are taken for the plug-in with defects in the relay protection device each time, the service life of the replaced plug-in originally recorded in the plug-in information record is updated to obtain a new plug-in information record, so that the life cycle of the plug-in can be updated timely, and the life cycle management and control of the plug-in the relay protection device are more accurate.

In one embodiment, for each sub-plug-in information record in the updated plug-in information record, determining a remaining service life corresponding to each plug-in a site corresponding to the sub-plug-in information record according to the sub-plug-in information record; and according to the determined residual service life of each plug-in, determining the pre-warning date corresponding to each plug-in the site corresponding to the information record of the sub-plug-in, and carrying out pre-warning on the corresponding plug-in when the pre-warning date is reached.

In one embodiment, for each sub-plug-in information record in the updated plug-in information record, determining a respective initial use time and service life of each plug-in a site corresponding to the sub-plug-in information record according to the sub-plug-in information record; and determining the early warning date corresponding to each plug-in the site corresponding to the sub-plug-in information record according to the determined initial use time and service life corresponding to each plug-in, and carrying out early warning on the corresponding plug-in when the early warning date is reached.

Specifically, the plug-in information record is composed of sub-plug-in information records of each site, when a plug-in each site has a defect and after corresponding early warning measures are taken, the sub-information records of the site are updated, at the moment, the initial use time and the service life of each plug-in after the early warning measures are taken are determined again, the early warning date of each plug-in after the early warning measures are further obtained, and when the date reaches the early warning date, the corresponding plug-in is early warned.

Optionally, the early warning system of the relay protection device comprises a main station system and a substation system, and the main station system calls plug-in information records of the on-site relay protection device in real time through the substation system, wherein the plug-in information records comprise unique device identifiers, device models, device commissioning dates, plug-in number and plug-in information; the plug-in information includes: plug-in type (power strip plug-in, plug-in board plug-in, protection board plug-in, AC board plug-in, management board plug-in, communication board plug-in, bus board plug-in, display board plug-in), plug-in batch and model, plug-in software version, plug-in initial use time, plug-in service life time limit, and the like. The main station system calls the defect record information of the field relay protection device in real time through the sub-station system, and the defect record information of the sub-station system can be generated in two ways: the first is that the relay protection device has the functions of automatic identification and data analysis, automatically analyzes the defect problem to form a defect file, and sends an alarm signal to the master station system; and secondly, manually forming a defect file after the defect is eliminated, and triggering an alarm signal to a master station system.

Since the package information record includes sub-package information records of a plurality of sites. Therefore, when the early warning occurs, the position of the defective plug-in unit at which site is located can be quickly determined, and convenience is brought to subsequent maintenance and management.
