In this embodiment of the present invention, the step 103 includes:

acquiring information of a device to be tested of the tested substation according to the SSD topological graph of the tested substation and the SCD file of the tested substation;

extracting a test item matched with the information of the device to be tested of the tested transformer substation from a preset test item library, and generating a test scheme of the tested transformer substation according to the test item according to a preset arrangement rule;

outputting fault quantity to a device to be tested corresponding to the test project according to the test project in the test scheme, and setting protection logic node state information corresponding to the device to be tested in a target logic node model;

and comparing the state information set in the target logic node model with the actual running state information of the protection logic node of the corresponding device to be tested so as to perform project test on the substation to be tested and output a test result.

Specifically, with the SSD topological graph of the tested substation, the total number of sets of devices to be tested of the tested substation is obtained in combination with the SCD file of the tested substation, and information such as the model and the functional unit of the devices to be tested is specifically obtained, so as to extract the test items matched with the devices to be tested from the preset test item library. And reasonably arranging all test items of all devices to be tested according to a preset arrangement rule, and further generating a test scheme suitable for the tested transformer substation.

In an embodiment of the present invention, the step of extracting a test item matched with the device to be tested from a preset test item library, and generating a test scheme of the substation to be tested from the test item according to a preset arrangement rule includes:

acquiring a protection logic node of the device to be tested, and extracting a test item matched with the protection logic node from a preset test item library;

and generating the test scheme of the tested transformer substation according to the extracted test items according to a preset arrangement rule.

Specifically, a device to be tested is subdivided into a plurality of protection logic nodes according to functions, each protection logic node has an independent function, and different functions correspond to different test items. And then, by acquiring the protection logic node of the device to be tested, the test items matched with the protection logic node can be extracted from a preset test item library, and all the test items are generated into the test scheme of the substation to be tested according to a preset arrangement rule.

And further, according to the test items, outputting the fault quantity to the device to be tested by a fault quantity module, and correspondingly setting the state information of the protection logic node corresponding to the device to be tested in the target logic node model. The full-automatic closed-loop detection device of the intelligent substation performs information interaction with an SV interface, a GOOSE interface and an MMS interface of the device to be tested based on the test communication network, realizes test closed-loop through SV and GOOSE services, and reads equipment logic node state information of the device to be tested through the MMS service.

And comparing the state information set in the target logic node model with the actual running state information of the corresponding protection logic node of the device to be tested, and outputting a corresponding comparison result by the device to be tested so as to complete the closed-loop test.

It should be noted that each logical node corresponds to one test item in the test item library, and each test item may include a plurality of test specials.

For example, for a line protection device having differential protection and distance protection logical nodes, a corresponding test item PDIF _ T1 is preset based on a differential protection logical node PDIF, and a corresponding item PDIS _ T1 is preset based on a distance protection logical node PDIS. In the test items, a corresponding test specific item PDIF _ T1_ D is preset for a fixed value D in the logical node. For a fixed differential protection PDIF, the differential principle is fixed, and the fixed value and the control word name are fixed, so the corresponding test item and the test item are also fixed, and the test item PDIF _ T1 is stored as the corresponding test item of the differential protection PDIF, and the test item may be expanded in consideration of the scalability of the PDIF differential protection principle, and may be distinguished by the suffix names T1, T2, and the like. For the logic node fixed value accuracy test, a sudden excitation quantity mode is adopted, and within a given error value range, a clear relay action standard exists, for example, for a PDIF differential protection action fixed value D, the error is allowed to be 5%, when the sudden excitation quantity is 0.95D, the regulation requires that the relay does not act, and when the sudden excitation quantity is 1.05D, the regulation requires that the relay reliably acts.

Analyzing the SSD topological graph of the transformer substation to be tested through the XML analysis module, reading the logic node information of the device to be tested, and searching a corresponding test item from a preset test item library according to the logic node information to form a target device test item. And extracting model information of the device to be tested from the target equipment test project, and storing the model information as a target logic node model.

And the test platform fault quantity module carries out SV sampling data communication with the device to be tested through a test communication network, outputs corresponding test fault quantity to the device to be tested according to preset test items, simultaneously assigns corresponding equipment logic nodes in the target logic node model, and stores the obtained logic node target information in the target logic node model. In the specific implementation process, by means of SV service, the fault amount of a test item is output at the time of T0, and state assignment is carried out on related data in a target logic node model. For example, an action constant value test with the test content of the differential protection PDIF being 0.95D is performed, and while 0.95D fault quantity is output, the 'False' assignment is performed on the PDIF.OP in the target logic node model; and (3) carrying out a differential protection action constant value test with the test content of 1.05D, and carrying out 'True' assignment on the PDIF.OP in the target logic node model.

Meanwhile, the GOOSE information module performs GOOSE information interaction with the device to be tested through the test network, and records the protection action time T1 in the GOOSE message in the GOOSE information module. In addition, the test platform also obtains the device action event report through the MMS service of the station control layer interface, and stores the relevant information in the report in the device logic node state information.

And finally, respectively reading corresponding action time data of the device to be tested in the state information of the target logic node model and the state information of the equipment logic node, and carrying out consistency comparison, wherein if the data are consistent, the action protection result is correct, and otherwise, the action result is incorrect. For example, the test platform finds the protection action event report "brcbtriplnfo" at the time T1 according to the protection action time, reads "pdif.op" in the corresponding data set from the protection action event report, compares the "pdif.op" with the "pdif.op" in the target logical node model, verifies whether the test result meets the standard expectation, generates the test result, and generates or prints the test result into a test report in a standard format.

In the embodiment of the invention, the SCD file of the tested transformer substation is compared with the equipment type data template file to judge whether the SCD file configuration information of the tested transformer substation is correct or not; when the SCD file configuration information of the tested transformer substation is judged to be correct, analyzing the SCD file of the tested transformer substation and generating an SSD topological graph of the tested transformer substation; and acquiring a test item from a preset test item library based on the SSD topological graph of the tested transformer substation, generating a test scheme of the tested transformer substation, carrying out item test, and outputting a test result. Therefore, test items can be automatically generated according to the system structure and the equipment configuration information of the transformer substation, and the device to be tested of the transformer substation can be automatically subjected to item testing, so that the visual level of closed-loop testing of the transformer substation is improved, and the working intensity of transformer substation workers is reduced.

And searching external connection points of the line interval and each side interval of the main transformer, and marking as bus connection points such as Mn. The wiring pattern of the line spacing and the main high/medium/low voltage side spacing is determined according to the following principle: the number of the circuit breakers is 3, and the number of the bus connecting points is 2, wherein the bus connecting points are 3/2 circuit breaker wiring intervals; the circuit breaker is provided with 1 circuit breaker, and the bus connection points are 2 bus connection intervals; the circuit breaker is provided with 1 circuit breaker, and the 1 bus connection point is a single bus wiring interval; the others are abnormal conditions. And determining the wiring mode of each voltage grade according to the number of bus connecting points, the line interval and the wiring mode of each side interval of the main transformer, and finding the paired parallel buses for the double-bus wiring.

And 203, generating interval topological feature codes according to the interval information, and acquiring an interval wiring diagram template matched with the interval topological feature codes from a preset interval equipment diagram template library to generate an interval wiring diagram.

Specifically, the interval information at least includes types of each device in the interval and a topological connection relationship thereof, and then an interval topological feature code is generated according to the interval information. For example, traversing each device in the interval from the bus connection point, and identifying the node type by a single letter, such as ' O ' for the bus connection point, ' L ' for the line "IFL ', ' K ' for the breaker" CBR ", etc.; traversing each node from a root node, numbering the nodes according to the sequence, combining the node type identification and the numbering into a topological characteristic character string, and placing the same-level nodes in the same-level brackets, for example: "O2- { G3- { D4, P5, V6}, D7 }".

Generating interval topological characteristic codes by the interval topological characteristic character strings, searching whether corresponding templates exist in a preset interval equipment graph template library or not according to the interval topological characteristic codes, if not, generating interval wiring diagram templates and storing the interval wiring diagram templates in the preset interval equipment graph template library, and if so, generating corresponding interval wiring diagrams according to the adaptive interval wiring diagram templates. This step is performed for each interval until a wiring diagram for all intervals is generated.
