Referring to fig. 1, an embodiment of the present invention provides a tervelum inspection system based on a secondary device intelligent management and control platform, so as to assist operation maintenance personnel in performing a more efficient tervelum inspection work. The tervelum inspection system comprises:

The data modeling function module of the special-dimension inspection system is mainly responsible for modeling work of a special-dimension level model, a special-dimension reference value model, a special-dimension service related expansion model, a check strategy model and a historical data model of primary equipment.

The automatic patrol function module of the tervelum system of the invention has the execution flow shown in figure 2, namely, the tervelum function reads the tervelum primary equipment list, tervelum patrol options and tervelum patrol plan, determines the equipment list needing to be checked due according to the tervelum patrol plan, performs various tervelum checks on the equipment in the list, generates tervelum patrol record and abnormal alarm after the execution is finished, and generates tervelum patrol report.

In addition to the task of the execution plan due, some of the dimension items also need to monitor some of the daily operational data of the device, providing basic data for dimension plan execution, i.e. "dimension basic tasks", including monitoring summons and analysis of the start-up recording, data collection of the longitudinal channels, etc. For a certain day, the automatic tour process flow is shown in fig. 3. After acquiring the equipment list for expiration checking of the present day, the terwei function initializes the terwei device list and the task list, executes terwei items such as constant value check, analog quantity check, soft pressing plate check, channel inspection, configuration check, historical event analysis, wave recording start report analysis, out-of-area fault analysis and the like device by device, and finally generates inspection records and terwei reports.

Further, the feature comprises a plurality of feature items, the deployment of which is shown in fig. 4, and specifically described as follows:

1) The device soft pressing plate shifts, enters the shift, gives an abnormal alarm, acts the incident, trouble information, records the wave file and obtains and analyzes through the historical inquiry.

2) The functions of soft pressing plate checking, opening amount checking, analog amount checking and homology ratio equivalent on-line acquire real-time data of the device and compare the real-time data with a reference value to judge whether the state of the device is normal or not.

3) Because the fixed value checking module is available, the fixed value checking function of the tervelar inspection preferentially acquires fixed value checking historical data in the tervelar period from the historical library, and if the fixed value checking historical data does not exist in the tervelar period, the fixed value checking is realized by triggering the fixed value checking module, and a checking result is acquired.

4) The pilot channel inspection is based on the historical data comparison of channel characteristic quantities (error code number, frame loss number, channel time delay and … …), so that a channel data recording module is required to be added to record the historical record of a channel, and a special-dimension inspection functional module analyzes whether the pilot channel is abnormal or not by reading the historical record.

5) The configuration verification of the terse directly acquires data from the history record of the configuration verification module, and if the data cannot be acquired, the configuration verification module is not triggered any more.

6) The out-of-zone fault analysis directly acquires data from the history of the intelligent alarm module, and if the data cannot be acquired, the intelligent alarm module is not triggered any more.

7) And (3) starting wave recording analysis: the method is implemented in a terveline inspection function module, and the starting wave recording file is required to be monitored and summoned, and is analyzed and a starting report is generated.

The interface of the manual patrol function module of the tervelum patrol system is shown in fig. 5, and primary equipment needing patrol can be selected in the interface, and the tervelum patrol function is triggered.

And selecting a primary device to be patrolled on the left side, clicking a button 'start patrol' above the middle to start to execute the special patrol, and clicking a 'cancel patrol' button to cancel patrol in the patrol process.

The "patrol status" column in the upper middle table displays the patrol progress, double-clicks one device, issues the patrol result of the device to be displayed, and supports the viewing of detailed information.

The right side of the interface displays the result of the tour, clicks the 'view' button in the form, and displays a detailed tour report of one tour. And supporting the record of the patrol result and the export of the patrol report. The results of the automatic tour and the manual tour are recorded in tables 1 to 9, respectively, by category.

The configuration management module of the tervelum inspection system is mainly responsible for flexibly and efficiently configuring tervelum primary equipment parameters, tervelum reference value parameters, homology comparison parameters, tervelum plan parameters, tervelum parameters and other parameters.

Further, as shown in fig. 6, a schematic diagram of a configuration interface of a tervelamer primary device is shown, and the layout design concept of the interface is as follows:

1) The tree on the left gives the model tree of the substation and its primary equipment. And selecting the whole network, the region and the transformer substations, and displaying the deployment condition of the transformer substation terwei according to the transformer substations (including non terwei stations) governed by the left selection object in the upper right table.

2) The upper right table switches records (substations), and the lower right table shows the primary devices and their terse levels of the newly selected substations.

3) The lower right table primary device may be modified to modify the substation tertbie level (meeting the tertbie level definition requirements).

4) After the primary device feature level is determined, the actual corresponding secondary device feature level is also determined.

5) It should be noted that some secondary devices may be associated with multiple primary devices (e.g., 3/2 wire breaker protection, bus tie breaker protection, protection for multiple sections of bus bars simultaneously, etc.), repeated recording should be allowed during computation, and missing secondary devices are avoided.

FIG. 7 is a schematic diagram of a specific dimension reference value configuration interface, and the design concept of the interface layout is as follows:

1) The tree is provided on the left side, the primary device needing to configure the reference value can be selected (the option can be provided to decide whether the non-special station and the non-special device need to be displayed or not), and the reference value configuration is performed on the right side.

2) The upper right table gives the secondary devices associated with the selected primary devices on the tree, note that deduplication is required (the selected primary devices are associated with the same secondary device), select a row (table selection, not checkup selection), and the lower right table gives the reference value corresponding to the secondary device.

3) The standard value can be generated by calling the fixed value, the analog quantity, the soft pressing plate and the entering quantity, and the batch calling of the secondary equipment quantity value is realized by checking a check box of the upper table and a calling quantity value button above the table and is stored as the standard value.

4) For the constant value list value, the reference value can also be generated by importing the constant value list (the constant value list can be imported in batches at the pop-up interface).

5) Direct editing of the reference value (editing of the new value field) in the lower right table is supported.

Fig. 8 is a schematic diagram of a local interface of analog quantity homologous comparison configuration, and the design concept of the interface layout is as follows:

1) The left Bian Shu selects a primary device, the upper right left table will show a configured homology value list, the upper right is an associated secondary device list of the primary device, the lower right is a data point list of a certain secondary device selected by the upper right, and the lower left right is a source data point to be compared corresponding to the homology value selected by the upper left right.

2) The manual newly-built homologous comparison configuration process comprises the following steps: the upper left table on the right adds a homology value record, which means that a certain electric quantity can be measured by a plurality of protections; and selecting a secondary device on the right upper side, displaying the information point of the secondary device on the right lower side, and adding a point to be compared to the homology value (adding a record in the right lower left table) when selecting a certain information point.

3) The number of the homologous value points is large, and the manual configuration workload is large point by point, so that the automatic generation of the homologous value points by a certain strategy is also considered. To this end, an "auto create Main protection analog Point" button is provided, and clicking on this button will generate a homology alignment configuration for all the Main protection of the present primary device (i.e., compare the main homology information in the Main protection). The generation logic is as follows: and (3) matching is automatically carried out according to the name and the type (Ia, ib, ic and the like) of the protection analog quantity point, a homologous quantity value is generated if matching is carried out, and meanwhile, the protection information point is added to a data source of the homologous quantity value. The automatically generated points default to three-phase current and three-phase voltage, and the three-phase current and three-phase voltage on the three sides of high, medium and low are distinguished for the main transformer.

As shown in FIG. 9, which is an exploded view of the task, since the task is typically reported in units of primary devices, stations, the task of the same substation, primary device, is preferably focused to a smaller time period for completion, e.g., the task of a single station is completed within 1 day. For tasks that are not completed for some reason (e.g., device communication is interrupted, the master station has other tasks), it is desirable to complete as soon as possible if the condition is met. The invention considers that the substation and the primary equipment are taken as units to make a special dimension plan for the secondary equipment of all the special dimension stations, and the configuration interface is shown in figure 10.

There are two ways to generate a te-dimensional plan:

1) One-key full-network automatic generation

(a) According to the feature level, the device patrol is evenly distributed to each day in the period, and the starting time of the patrol every day is automatically set. The minimum period is 1 month, the period can be used as a patrol period in a season and on a specified day, the realization is simple, and the task allocation is not considered in the period of 29-31 days in the month and the season.

(b) Each level is automatically set one pass according to a respective default period.

2) Custom configuration

The object(s) are manually selected, the period (default given by the tervey level), the start date, the day start time (day, time division), the specified date plus the period multiple is the tour date of these devices, and the period can be month, season, specified days.

And when the one-key automatic configuration plan for the tervels is carried out, the allocation is carried out by taking stations as units. The custom configuration is distributed in units of primary devices, and multiple devices under the termaine primary device are not allowed to be split into different tour plans.

FIG. 11 is a diagram of a configuration of parameters for a dimension, the interface design concept is as follows:

1) Tour plan configuration: the method comprises the following steps of patrol periods of each level of terylen, default starting time of daily patrol, and maximum number of devices to be patrol daily.

2) Tour item configuration: which functional items are patrolled by default.

3) Analog quantity patrol configuration: and configuring various thresholds of the analog quantity inspection function.

4) And (3) opening amount inspection configuration: whether to perform the open-ended homology comparison (comparison with OCS).

5) And (3) a longitudinal communication channel patrol configuration: including various threshold configurations for dedicated channels, multiplexed channels.

Compared with the prior art, the embodiment of the invention has the beneficial effects that the operation maintenance means of the relay protection and self-installation device can be enriched and optimized to a great extent, and special maintenance items are added for the key relay protection and self-installation device so as to realize more efficient and fine equipment operation and maintenance.
