Detailed description of the invention
For further setting forth the effect of technological means that the present invention takes and acquirement, below in conjunction with accompanying drawing and preferred embodiment, to technical scheme, carry out clear and complete description.
Refer to Fig. 1, for the schematic flow sheet of the generation method of transformer station of the present invention SCD model file.The generation method of transformer station of the present invention SCD model file, comprises the following steps:
S101 obtains directory information and the data message of each IED of transformer station;
As one of them embodiment, the oneself of the available MMS based on IEC61850 (ManufacturingMessagingSpecification is called for short MMS) server states characteristic and obtains directory information and the data message of each IED of transformer station.Described directory information includes catalog structure information, and described data message includes data attribute information, data initial value information and data set composition information.
Described directory information and data message and IEC61850 model specification are contrasted by S102, obtain the data needed for IED corresponding part in SCD model file;
As one of them embodiment, needed for described SCD model file, the data of various piece include common data class, logical node class, IED example information and network access point information.According to IEC61850-7-3 and IEC61850-7-4, the bibliographic structure of IED, data attribute, data initial value are analyzed, obtain the various piece data needed for SCD model, mainly include used common data class and logical node class, IED example information, network access point information.
The step obtaining in SCD model file the data needed for IED corresponding part includes:
Step 1: propose all of logical node example information from the catalog structure information of IED, contrasts its name with logical node class in IEC61850-7-4, decomposites logical node class name and such Instance Name of compatibility;Citing: comprise the logical nodes such as LLN0, SIML1, SIML2, SPDC1 in the directory information of certain IED, we can find the logical node classes such as LLN0, SIML, SPDC of correspondence in IEC61850-7-4, so that it is determined that logical node class name, measured SIML logical node class and Instance Name " 1 " thereof can be analyzed from SIML1, prefix is empty, by that analogy;
Step 2: propose the data attribute example of all of data class example and the inside thereof from the bibliographic structure of IED and data attribute;
Step 3: the data instance name inside logical node class that data class Instance Name step 2 obtained and step 1 obtain contrasts, obtains the common data class (being called for short CDC) to use;Citing: as having one by name " Mod " and data object example that functional restraint is " ST " below SIML1 logical node, and inside " SIML " logical node class of standard, also pre-defined one by name " Mod " and data object example that functional restraint is " ST ", but also defining data class corresponding to this data class example is single-point state class (being called for short SPS), thus may determine that the CDC of the data of SIML1 " Mod " correspondence is " SPS ", by that analogy;
If there being the growth data that " SIML " logical node class of standard does not comprise below SIML1 logical node, so can first judge the scope of CDC according to functional restraint, contrast one by one obtain concrete CDC again through the data attribute of this growth data and the CDC within the scope of this;
Step 4: contrast one by one according to the data attribute example inside the data class example that the DAType of the data attribute of the defined CDC of IEC618507-3 and various standard is obtained with step 2, finds common data Attribute class (being called for short DAType) and bType that matching degree is the highest;
Determined the DAType of the data attribute of standard by known CDC, for off-gauge data attribute, adopt the DAType obtaining off-gauge data attribute with the known DAType method compared one by one.As the Mod data below SIML1 logical node example have a data attribute extended, exInfo1 by name, functional restraint is " EX ", and not comprising the known exInfo1 of $ from name is a simple data, therefore can directly determine the bType of these data;And for example another attribute exInfo2 mag f by name, functional restraint is " MX ", its data type is float32, all DAType in conjunction with exInfo2 $ mag $ f Searching I EC618507-3 the best can determine that " exInfo2 " be type is the SDO of " MV ", the bType of " mag " is " struct ", and DAType corresponding for mag is the analogue value;
Step 5: the information obtained according to the data initial value information integrating step 1,2,3 and 4 of IED determines SDI, DOI and the DAI configuration information of model;
Step 6: determine that buffer memory report-control block, non-caching report-control block, log control block, GOOSE control the definition information of block and the title of associated data set respectively according to BR, RP, LG, GO of comprising in IED data message and initial value information thereof;
Step 7: determine that definite value group controls the definition information of block according to the SGCB information in IED data message;
Step 8: form information according to IED data set and determine the content of data set;
In above step, the execution sequence of step 1 and step 2 can exchange, step 5,6,7 and 8 execution sequence can exchange.
Data needed for IED corresponding part in described SCD model file are write SCD formatted file by S103.
As one of them embodiment, according to the SCL of IEC61850 rule, the data of the data needed for IED corresponding part in described SCD model file and the other parts obtained of gathering and editing are converted into the SCD model file of standard.
Common data class and logical node class, IED example information, network access point information are converted into the SCD file of standard by the SCL rule according to IEC61850.SCD model information is except the data message including IED, also include network configuration information and the primary equipment configuration information at full station, network configuration information includes the configuration parameter of each layer of network of main website and distributed apparatus, such as MAC Address, IP address, session address, transmitting-receiving time-out, maximum message size, maximum number of connections order etc., these information can pass through function extraction from the current network profile of main website of gathering and editing of SCD model creation program.
Compared with general technology, the generation method of transformer station of the present invention SCD model file, transformer station's SCD model file can be automatically generated by online mode, it is possible to create SCD model file exactly, and without manual intervention.Accurately realize SCD model file content synchronization with transformer substation system practical situation, rapidly adapt to the change that substation network system occurs.
