Background Art

With the expansion of the scale of the digital transformer substation building, how to check each device manufacturers provide the model file is correct is a need to immediately solve, a large amount of work. Now the way to adopt is the focus of the substation equipment, through use of the moving way to model verification, not only large workload, and the efficiency is low, once started to build on a large scale the digitized transformer substation, this way has no practical application value. Verification using mode by moving the protection of the integrity of the document and correctness of the model has the following limitations:

1. Debugging site problems. A substation to the number of secondary equipment for less novelrotary 80 surface, more nearly 200 surface, with these novelrotary background, the system equipment such as the substation, about to be occupied more than 500 sq m to the indoor space. This side the large local, if debugging a two station are still possible, if the number of transformer substation, may have a problem.

2. Debugging time. Test of total station is generally 2 months. The corresponding manufacturers and debugging units to fit needs to be sent. If the transformer substation, could not cause the human.

3. Debugging workload. Due to the debugging 2 months, needs to be in the room the condition of the field to simulate the transformer substation, the workload almost equivalent to the workload of the spot.

4. Debugging the problem of cost. For a long time, a large amount of workload, multi-device, multi-human debugging the debugging costs with a large amount. These costs to the user, manufacturers cause enormous economic pressure.

Content of the invention

The aim of the invention is to solve the above-mentioned problem, provides a substation configuration description file based on the digitized transformer station information simulation system, through the network, computer simulation the protection information output, the correctness of the detection model; can be the maximum reduction of the cost of the die test; can greatly improve the speed and reliability of the verification of the model.

The technical proposal of this invention: the invention discloses a substation configuration description file based on the digital transformer substation analog system of information, including:

Model file to introduce into the module, the substation of the configuration file of the merger;

Database module, is connected with the model file import module, receives the model file to introduce into the module after the merger of the output of the transformer substation configuration file;

Information control module, is connected to the database module, the database module from acquiring the action information, and according to the simulated needs to generate instruction;

Emulation protection module, is connected with the database module and the information control module, is read in from the database module into the module through the model data of the document, generates a corresponding virtual protection apparatus, and receives the information control module generating instruction, containing action, alarm information.

According to the invention on the basis of the substation configuration description document of the digital transformer substation information of one embodiment of the analog system, the substation configuration file includes a transformer substation in order to describe the situation of secondary equipment configuration substation configuration description file.

According to the invention on the basis of the substation configuration description document of the digital transformer substation information simulation of one embodiment of the system, the model file to introduce into the module verifies the correctness of the substation configuration description file, through the decomposition of substation configuration description file, the substation configuration description document in accordance with the protection device of a value information comprising protection device, protective equipment alarm information, action information protection device, protective device analog information and protection device of the data information of the switching information.

According to the invention on the basis of the substation configuration description document of the digital transformer substation information simulation of one embodiment of the system, the information control module on the basis of the more data information for manual or automatic analog, according to the test needs to generate in order to drive this emulation protection module to give true protection equipment may send the information of the instruction.

According to the invention on the basis of the substation configuration description document of the digital transformer substation information of one embodiment of the analog system, the emulation protection module reading a substation configuration description file, map generation analog protection model structure, receiving the information instruction of the control module, to return to the corresponding information to the information control module.

The invention compared with the prior art have the following beneficial effects: the technical scheme of the present invention is composed of a model file to introduce into the module, the database module, information control module and the emulation protection module, the substation configuration description file based on the digital transformer substation analog system of information real simulation information output protection device, transformer substation for the inspection of a model structure of the protection device provides a practicable, efficient method.

Mode of execution

The embodiment of Figure and with the further description of this invention.

Figure 1 show the substation configuration the invention is based on the description document of the digital transformer substation analog system of information of the structure of the embodiment. Please refer to fig. 1, this embodiment of the substation configuration description file based on the digitized transformer station information simulation system comprising: model file import module 1, the database module 2, information control module 3 and the simulation protection module 4.

The connecting relationship between them is: model file to introduce into the module 1 is connected with the output end of the database module 2 of the input end, the database module 2 are respectively connected with the output end of the information control module 3 and simulation protection module of the input end of the 4 input, information control module 3 simulation protection module is connected with the output end of 4 the input end.

Model file import module 1 of the substation configuration file will be re-finishing and merging, store in a database, for other module. Here the configuration file includes transformer substation configuration description file (SCD file,   Description   Configuration Substation), the SCD file description of secondary equipment configuration, SCD not only for monitoring background of the document, but also for the protection of information management system using the substation. SCD file contains the protective device, the detailed information of an oscilloscope and other equipment described, the protection device also includes the constant value, an analog quantity, value, protection action, alarm protection, protection information such as recording paper. SCD document is intelligent device structure to describe various devices (CID,   IED   Description Configured) a processor of the file. Model file to introduce into the module 1 is responsible for verifying the correctness of the SCD file, document through the decomposition of SCD, SCD document in accordance with the protection device will be decomposed into a protection value information of the equipment, protective equipment alarm information, action information protection device, protective device analog information and protection equipment data information to a switching value information and the like. Model file import module 1 operating mechanism as shown in Figure 4.

Database module 2 receiving model file to introduce into the module 1 of the output of the document after the merger of SCD, for storage purposes.

Information control module 3 from the database module 2 in the information acquisition operation, and according to the simulated needs to generate instruction. Information control module 3 according to the model file to introduce into the module 1 of the decomposed data information for manual or automatic analog, according to the test needs to the simulation protection module 4 transmits a command, in order to drive the artificial protection module 4 may be a real protection device issued the information.
