61850 standards systems of IEC:
IEC61850 standards are widely used in intelligent substation, and standards system and application specification gradually refine. 61850 standards of IEC have unified the information model inside substation, the specification communication interface of whole station all devices.Standard defines Supervisory control of substation automated system is made of the three-layer network framework of station level, wall, process layer, it is proposed that SCL information The technologies such as model and description, Abstract Common Service Interface (ACSI), particular communication service mapping (SCSM), realize equipment room The scalability of interoperability and whole station function.
IEC61850 standards are by the unified Modeling thought of object-oriented by the performance data of smart machine and system according to patrolling Volume equipment, logical node, data object, data attribute mode tissue and structure are come with tree structure, form various SCL moulds Type.
Define ICD file structures for device IED in IEC 61850, standard include channel information, logical device, The formats such as logical node, data object, data attribute.
SCL uses XMLSchema document type definition SCL file structures in IEC 61850-6, with SCL.xsd in standard As master file, other 7 Schema files, the correctness for verifying IED configuration file formats and number are quoted and contained It is believed that the validity of breath.
IEC61850 uses standardized Communication Service Interface technology to realize the interoperability of equipment room.It is controlled at station Layer network uses IEC 61850/MMS Standardization Communication services, realizes access observing and controlling, protection, PMU, fault oscillograph, one The equipment such as secondary device status monitoring and subsystem.In station level or process-level network, standardized using IEC61850/GOOSE logical The real-time packet that telecommunications services are used between equipment quickly transmits, and realizes the connection locking between network tripping and equipment.In process layer Network transmits communication service using the standardized sampled values of IEC 61850-9-2, realizes the network transmission of sampled measurement.
Sampled value transmission standard system:
The information capacity of substation greatly improved in the Digital Transmission pattern electrically sampled, simplifies the information of substation Shared and equipment room interoperability.Currently, sampled value transmission mode includes mainly IEC60044- in the engineering construction of intelligent substation The modes such as 8FT3 point-to-point transmission, IEC61850-9-2 point-to-point transmission and IEC61850-9-2 networkings transmission, IEC60044- 8FT3 uses serial data transmission mode.IEC61850-9-2 agreements are according to sample values mould as defined in IEC61850-7-2 The particular communication service mapping that transmission sampled value is communicated between the process layer and wall of type and correlation ACSI service definitions, is supported Change to data set and the direct access to data object;Frame format can be defined flexibly, and support mode of unicast, to ASCI moulds The support of type is also more complete.IEC61850-9-2 includes point-to-point transmission mode and networking transmission mode.Point-to-point mode is suitable For monospace or to data synchronism occasion of less demanding, networking mode is suitble to be spaced more data transmission applications.
Manufacture message specification MMS:
The people's distinguishing features of IEC6150 technically be exactly just used the purpose of manufacture message specification MMS, MMS be for Specification industrial circle has the communication behavior of the intelligence sensor of communication capacity, intelligent electronic device, intelligent control device, makes The equipment networking for coming from different manufacturers provides a convenient, it is easy to accomplish information mutual communication and resource-sharing, as long as meeting MMS marks The accurate equipment that can realize identical function can be carried out equipment replacement.The communication of substation level and wall is using abstract logical Telecommunications services interface ACSI is mapped to MMS.
SCD file parses:
SCD file is described by XML file format, has DOM for the mainstream analytic technique of XML file (Document Object Model, DOM Document Object Model) analytic method and the SAX (letters of Simple API for XML, XML Single API models) analytic method.Both interface specifications emphasize particularly on different fields, mutual length, using all than wide.DOM modes are handles Entire XML document is converted to dom tree and has been placed in memory, and application program can access any in XML document at any time A part of data, therefore, when document comparison is big or structure is more complicated, the demand to memory is with regard to relatively high.SAX be it is a kind of by Row scanned document parses while scanning, and access speed is fast, efficient, but does not support random access.It considers herein SCD file scale will not be too huge, and the method for having selected DOM is solved plus Xpath (XML Path Language) technology Analysis.Xpath is the path language based on object model DOM, can use convenient and efficient some specific node of lookup of Xpath, or Search all nodes with some condition coupling.Xpath technologies are effectively utilized, complicated recursive operation can be skipped, are improved The operational efficiency of program.
The protection definite value of tested protective relaying device can be obtained by parsing SCD file;
SCD Context resolution program circuits:
The first step loads SCD file and forms dom tree, and fills element, and PCDATA, CDATA block are extended.Pass through simultaneously XPath technical limit spacings key element and attribute, for example IED list xpath_node_set IED_list are obtained by XPath =doc.select_nodes ("/SCL/IED "), then traverse xpaht_node_set containers extract each IED title, The parameters such as type;
Second step establishes the Hash table of data template, is searched for subsequent data, greatly improves search speed.
Third walks, and obtains the messaging parameter of control block.Xpath_node_set ConnectedAP_list= doc.select_nodes("/SCL/Communication/SubNetwork/Con nectedAP");Obtain all GSE, MAC-Address, VLAN-ID, APPID messaging parameter of SMV;
4th step, the messaging parameter according to GSE, SMV searches corresponding data collection in IED nodes and corresponding channel is retouched It states, channel leaf node;
5th step obtains GOOSE, SMV and subscribes to.The virtual terminator subscribed into Inputs node acquisition device;
6th step searches the incidence relation of device according to the relationship subscribed to and issued.
Promote the key of resolution speed:It can be related to very more repetition lookups and program during 4th step most Time-consuming place, in order to improve resolution speed, we will use hash algorithm here, this is also the pass for capableing of fast resolving herein Where key." hash " is done in Hash, general translation, and it is " Hash " also to have direct transliteration, and exactly the input of random length (is called It is preliminary mapping, pre-image), by hashing algorithm, it is transformed into the output of regular length, which is exactly hashed value.This turn It is a kind of compression mapping to change, it is, the space of hashed value is generally much less than the space inputted, different inputs may hash At identical output, and it can not possibly uniquely determine input value from hashed value.It is exactly briefly a kind of by random length Function of the message compression to the eap-message digest of a certain regular length.Hash be mainly used in information security field Encryption Algorithm and It quickly searches, it is converted to the information of some different lengths 128 mixed and disorderly codings, these encoded radios are called HASH values It may also be said that Hash is exactly the mapping relations found between a kind of data content and data storage address.What hash algorithm was realized Mode has very much, realizes hash algorithm using Fibonacci (Fibonacci) hashing herein, its basic principle such as Fig. 2 It is shown.
It is clear that a array, each member of array includes a pointer, is directed toward the head of a chained list on the left side, certainly this A chained list may be sky, it is also possible to which there are many element.We are according to some features of element in Elemental partition to different chained lists It goes, and according to these features, finds correct chained list, then find out this element from chained list.
The second step of this paper establishes three Hash tables, respectively below by (/SCL/DataTypeTemplates) LNodeType nodes establish Hash table with its id fields, and DOType nodes establish Hash table, DAType sections with its id fields Point with its id fields establish Hash table in this way we by FCDA node checks when, so that it may with quickly find very much need The data wanted.
Performance test:We pass through this under Intel (R) Core (TM) i5-4210U@1.70GHz1.8GHz processors Test result is as follows for the SCD file resolution speed of kind mode:The SCD file resolution speed of 40M 1 second, the SCD file parsing of 70M Speed 2 seconds, the SCD file of 175M 4 seconds, after file is big, the bottleneck of speed is exactly the process that device file forms DOM, Resolution speed in this manner has reached industry-leading level, and engineering efficiency greatly improved.
