Description
Technical field
The present invention relates to electric power system power distribution field of terminal technology, particularly a kind of method of the plug and play distribution terminal information realization automatic mapping based on CID file.
Background technology
Distribution terminal is multi-point and wide-ranging, all adopts IEC60870-5-101/104 communication protocol to communicate with distribution main station system at present.These general communication stipulations solve only the problem of transfer of data, do not solve the problem of data " what is "; Data are according to type packing transmission such as measured value, state value, controlled quentity controlled variables, there is data implication to fail to understand, onrelevant between data, need between distribution terminal and distribution main website manually to join a little, and specified data implication, need to carry out complexity, consuming time artificial to point process at the scene during debugging between distribution terminal and distribution main website.Meanwhile, distribution terminal initial information point table is general and distribution main website is inconsistent, needs to carry out a table configuration effort when engineering construction, and the configuration of some table is all adopt producer's user-defined format and special configuration tool software, cannot unify between each producer.The large-scale application of these problems affect power distribution automations is implemented.
From 2004 so far, IEC61850 has had the application experience of more than 10 year, have accumulated a large amount of engineer applied experiences in automation of transformation substations field.It adopts self-described mode to solve Interoperability in electric substation automation system between different manufacturers IED.
Do not have application to distribution network IEC61850 technical specification to issue temporarily at present, but IEC61850 related work group WG10 and WG17 is formulating IEC61850 application guide technological document IEC61850-90-6 in distribution automation system.Can predict, a developing direction in power distribution automation future is exactly use for reference the application experience of IEC61850 in transformer station, in conjunction with the demand of power distribution automation, the application of expansion IEC61850 in distribution, solve the Interoperability between different manufacturers distribution terminal, between distribution terminal and distribution main website, reduce distribution terminal project installation, debugging and maintenance technology threshold simultaneously, realize distribution terminal plug and play, improve the efficiency of the practice of power distribution automation.
At present under the advocating of Chinese DianKeYuan, organized a discussion the distribution IEC61850 standard of sing on web service, its technical scheme adopted is IEC104+WebService, i.e. real-time three distant data IEC104 stipulations transmission, off-line data (comprising model file, historical data etc.) the IEC61850 communication service mapping of standard realizes to WebService, but its be moving party to, concrete solution is not provided for the problems referred to above.
Technical term is explained:
(1) ICD:IED capabilities description file, describes the ability of IED device, uses template definition logical node, data and service, is provided by distribution terminal.
(2) CID: configuration describing document, instantiation ICD file.
(3) short address: sAddr attribute is for distributing short address to DO attribute, and short address can be used for attribute as intelligent electronic device internal indicator.
(4) WebService: the interface being description one group operation, these operations can be conducted interviews on network by the XML message of standard, and it also meets OSI7 layer protocol.Main definitions application program realizes interoperability on internet.Mainly in order to enable a kind of interface that between original each isolated website, information intercoms mutually and shares and propose.WebService to use on internet unified, open standard, as HTTP, XML, SOAP (Simple Object Access Protocol), WSDL etc., so WebService can use in the environment (Windows, Linux) of any these standards of support.
(5) IEC_60870_5_104: a kind of data structure, in CID file, for describing IEC104 information, its model XMLSchema is described below:
<xs:complexTypename＝"tIEC_60870_5_104">
<xs:attributename＝"casdu"type＝"xs:unsignedInt"use＝"optional"/>
<xs:attributename＝"ioa"type＝"xs:unsignedInt"use＝"optional"/>
<xs:attributename＝"ti"type＝"xs:unsignedInt"use＝"optional"/>
</xs:complexType>。
Summary of the invention
For the problems referred to above, the CID file that the object of the present invention is to provide a kind of employing to meet IEC61850 standard just can realize unified configuration and automatically realize the method for distribution terminal information to distribution master information automatic mapping.
The present invention solves the technical scheme that its problem adopts:
Based on a method for the plug and play distribution terminal information realization automatic mapping of CID file, it is characterized in that, comprise the following steps:
(1) CID file generated step
Distribution terminal is according to three remote sensing information point tables of device, according to short address sAddr and IEC_60870_5_104 information format, generate the self-described configuration ICD file of distribution terminal reference format, again by IEC61850 system configuration utility, according to the planning of power distribution automation, instantiation generation is carried out to ICD file, and the CID file download generated to distribution terminal, is kept at distribution main website simultaneously;
(2) distribution terminal information MAP step
Distribution terminal powers on, reading downloads to the CID file of distribution terminal and carries out file verification, the DOI element in CID file is searched after verification is normal, and " short address " information in DOI element and " IEC_60870_5_104 " information are extracted and is saved in corresponding data structure, travel through the full detail point in CID file and be kept in internal memory, then according to the order of remote signalling, remote measurement, remote control, full detail having been converted to the tabular information of upper IEC104 point;
(3) distribution master information mapping step
Distribution main website resolves and file verification the CID file be saved on it, information reference is extracted after verification is normal, IEC104 information point table is gone out according to " IEC_60870_5_104 " information analysis, go out corresponding name of the information by " dU " element extraction, and generate distribution main website data display list database;
(4) information automatic mapping step
Distribution main website and distribution terminal are by IEC104 agreement swap data, realize the real-time Transmission of three remote sensing informations, distribution main website according to the address resolution of IEC104 information object go out response data and automatically corresponding with display list database, automatically complete the information MAP of distribution terminal and distribution main website.
The invention has the beneficial effects as follows:
The present invention is in distribution terminal reference format self-described CID file, by short address sAddr and IEC_60870_5_104 information element, the inner three distant (remote signalling of distribution terminal are described out, remote measurement, remote control) information point table with to upper IEC104 tri-remote sensing information point table corresponding relation, distribution terminal according to rule parsing go out internal information with to upper IEC104 information MAP table, distribution main website is according to CID file and go out IEC104 information point table and corresponding namelist according to rule parsing, distribution main website and distribution terminal are by IEC104 agreement swap data, then distribution main website is corresponding to name of the information IEC104 information object address resolution real time data, automatically information MAP is completed.When power distribution automation engineering construction, adopt the CID file meeting IEC61850 standard, just unified configuration can be realized, automatically the mapping of distribution terminal information to distribution master information is realized, remove the human configuration of on-the-spot complicated, time-consuming, fallibility and information to a job, the efficiency of the practice of raising power distribution automation greatly.
