Based on the embodiments of the present invention, all other embodiments obtained by persons skilled in the art without any inventive work shall fall within the protection scope of the present invention, and the principle and features of the present invention shall be described below with reference to the accompanying drawings.
The terms "comprises" and "comprising," when used in this specification and claims, and in the accompanying drawings and figures, are intended to cover non-exclusive inclusions, such that a process, method or system, or apparatus that comprises a list of steps or elements is not limited to the listed steps or elements.
Referring to fig. 1, fig. 1 is a schematic flow chart of a platen visualization online checking method in a secondary safety measure according to an embodiment of the present invention, including:
s101, analyzing the SCD file of the configuration of the whole station, and automatically generating associated IED information, quoting information and transformer substation interval information after instantiating all channels;
the method comprises the steps of sequentially analyzing the SCD file, sequentially and respectively analyzing parts such as 'Header', 'status', 'Communication', 'IED', 'DataTypetemplates', and the like, processing the parts, instantiating all channels, automatically generating associated IED information, automatically generating reference information, automatically generating transformer Substation interval information, and converting the generated information into a configuration file of a current device.
S102, defining virtual terminal tables of various IEDs at different levels, and determining the corresponding relation between a virtual circuit and a soft pressing plate;
according to the standardized design specifications of line protection and auxiliary devices, the standardized design specifications of transformers, high-voltage shunt reactors and bus protection and auxiliary devices and the like, SV input virtual terminal tables, GOOSE input virtual terminal tables and GOOSE output virtual terminal tables of various IEDs at different levels can be defined, and the virtual terminal tables can be used as the alignment criteria of the soft pressing plates and the virtual circuits.
Generally, one SV link needs to correspond to one SV receiving soft pressing plate, and the virtual terminal table describes the pairing relation between SV input virtual terminal signal names and the soft pressing plates.
For example, in the case of a 3/2 breaker wiring protection device, part of SV is input into a virtual terminal table as follows:
table 1 SV input virtual terminal table
Specifically, according to the corresponding relationship in the virtual terminal table, the corresponding virtual terminal table can be searched and the name of the soft pressing plate can be determined by the signal name of the SV output link, and the corresponding soft pressing plate can be found in the data set. When the corresponding soft pressing plate cannot be found through the output link signal, a user-defined soft pressing plate can be set.
When any keyword of the intelligent terminal, the merging unit and the intelligent integration is contained in the description of the sending equipment, the GOOSE sending soft pressing plate is not set. And for other link signals, setting the soft pressing plate according to the virtual terminal table information in the standard.
For example, taking 3/2 breaker wiring protection device as an example, the partial GOOSE output virtual terminal table is as follows:
table 2 GOOSE output virtual terminal table
The operation process is as follows:
finding out signals of which all reference paths meet the requirement of PTRC and Tr, and classifying according to suffix node suffixes of the logical nodes;
finding soft pressing plates matched with PTRC and TrStrp in the data set, wherein the soft pressing plates with the suffixes of the same logic nodes are the soft pressing plates of the GOOSE output signals;
if any keyword of the intelligent terminal, the merging unit and the intelligent integration is contained in the description of the receiving equipment, the GOOSE receiving soft pressing plate is not set. When the soft pressing plates are matched, the corresponding signals are searched according to the signal name keywords, and then the corresponding soft pressing plates are searched according to the soft pressing plate keywords. If both the signal and the soft pressing plate can be found, the soft pressing plate is the receiving soft pressing plate of the GOOSE input signal. For bus protection and transformer protection equipment, when the signal description contains a 'failure' keyword, if a corresponding soft pressing plate is not found in a keyword matching mode, adding a soft pressing plate which is automatically received by GOOSE.

(4) For a dualized merging unit, when performing field verification, defect elimination and other work on a single device, the relevant primary device can continue to operate, but should exit the line protection, bus protection and the like associated with the merging unit.
(5) When the single set of configured merging units is verified and eliminated, the related primary equipment which runs at the interval is required to be out of service.
(6) Under the condition that primary equipment is out of service, if the on-site verification, defect elimination and other work of the merging unit are carried out, the SV soft pressing plate on the line protection of the interval and the SV soft pressing plate corresponding to the interval on the bus protection need to be withdrawn.
(7) For the dual-configuration intelligent terminal, when the single equipment works in field verification, defect elimination and the like, the related primary equipment can continue to operate, but the related protection reclosing function, the tripping and closing pressing plate of the intelligent terminal and the related devices which are possibly influenced are quitted according to the requirements.
(8) When a single set of configured intelligent terminals are subjected to field verification, defect elimination and other work, the running related primary equipment needs to be stopped, and meanwhile, the related devices which are possibly affected are quitted according to the needs.
(9) Before the protection device is operated to set the maintenance hard pressure plate, the protection device is changed into a signal state, and the soft pressure plate of the secondary circuit of the operation protection device such as the bus differential protection related to the protection device is withdrawn, such as the corresponding starting failure soft pressure plate.
(10) Under the condition that primary equipment is not in service, the interval protection device is changed into a signal or is stopped before the interval merging unit is put into service to arrange a maintenance hard pressing plate. Particularly, for the bus merging unit, under the condition that the bus is not in service, the bus merging unit is processed according to the abnormal condition of the bus voltage, and the merging unit can be put into service to overhaul the pressing plate after the bus voltage is switched.
(11) Under the condition that primary equipment is not in service, before the interval intelligent terminal is put into the maintenance hard pressing plate, the circuit breaker tripping and closing hard pressing plate of the intelligent terminal is withdrawn; exiting the reclosing function of the interval protection device; after the isolated isolation switch is forced to be closed on the bus protection corresponding to the intelligent terminal, the intelligent terminal can be put into the maintenance pressing plate.
The above 11 items are system summaries of relay protection safety measure principles, wherein the 1 st to 3 items are a general principle, the 4 th to 6 items are a safety measure principle when a merging unit is overhauled, the 7 th to 8 items are a safety measure principle when an intelligent terminal is overhauled, and the 9 th to 11 items are a safety measure principle of a relay protection device 'maintenance hard pressing plate'.

for example, (1) when the primary equipment is out of service, if the secondary equipment needs to be exited, the operation should be performed according to the following process:
i, quitting an SV soft pressing plate at the interval in the related operation protection device or putting the SV soft pressing plate at the interval;
II, exiting the GOOSE receiving soft pressure plate (such as starting failure) of the interval in the related operation protection device;
III, withdrawing the GOOSE sending soft pressing plate (such as a tripping pressing plate, a closing pressing plate and a starting failure pressing plate) of the protection of the interval;
IV, withdrawing the hard pressing plate at the outlet of the intelligent terminal at the interval;
v, putting the intelligent terminal, the merging unit and the protection device in the interval to be maintained and a hard pressing plate.
(2) When the secondary equipment is in a re-service state, the secondary equipment is put into operation, and the plate pressing operation is carried out according to the following process:
i, quitting an SV soft pressing plate at the interval in the related operation protection device or putting the SV soft pressing plate at the interval;
II, withdrawing the intelligent terminal, the merging unit and the protection device of the interval, and arranging a maintenance hard pressing plate;
III, putting the intelligent terminal outlet hard pressing plate at the interval;

and VI, throwing the SV soft pressing plate or the SV soft pressing plate into the related operation protection device at intervals.
Furthermore, when equipment breaks down, the fault needs to be isolated timely to ensure normal and safe operation of other equipment. And setting a corresponding isolation principle to obtain a secondary safety measure expert intelligent diagnosis library based on the difference of fault isolation ranges when the transformer substation equipment fails. The secondary safety measure expert intelligent diagnosis library can generate pressing plate switching strategies aiming at different maintenance faults, and different pressing plate switching strategies are adopted for maintenance in different fault types based on the corresponding relation between the virtual circuit and the soft pressing plate.
Illustratively, taking the example of the change of the 220kV master into different modes, the method includes:
national grid 92 mode: merging unit faults, protecting, merging, maintaining, exiting a GOOSE outlet, and operating a terminal; the protection unit fails, the GOOSE outlet is withdrawn, the combination and the terminal can continue to operate, and the terminal joint debugging is withdrawn after the defects are processed; the intelligent terminal is failed, the terminal is arranged for maintenance, an exit hard pressing plate is combined and protected to operate, a GOOSE exit is withdrawn, and after the defects are treated, the protection joint debugging is withdrawn;
and (3) associating shutdown modes: merging unit faults, protecting, merging, maintaining, exiting a GOOSE outlet, and operating a terminal; protecting any fault of the terminal, protecting the terminal, maintaining the terminal, pressing a hard pressing plate at an exit, and merging the operation; (merging unit failure, loss of protection, and accompanying and stopping protection due to joint debugging requirement; protection unit failure, possibly having the condition that a pressing plate cannot be operated and a terminal needs accompanying and stopping; terminal failure, loss of protection, and accompanying and stopping protection due to joint debugging requirement.)
