Background technology
《Guo Wang companies prevent 16 measures of transformer station's full cut-off》Clearly propose that " design protection of intelligent substation should adhere to
Relay protection " four property " principle, when should avoid the equipment faults such as combining unit, intelligent terminal, interchanger, while lose many sets protecting
Shield." protect in intelligent substation AC sampling to be realized by combining unit, combining unit as process layer nucleus equipment, its
The safe and stable operation of the Stability and dependability direct relation intelligent station of operation, especially a combining unit are protected to multiple
Transmission sampled value, once break down multiple protection exceptions may be caused to act.The intelligent station bus PT of current each manufacturer production
Combining unit cannot realize that different intelligent station substitutes the reason for using and is：
（1）It is different that the bus PT of each manufacturer production merges ICD files（ICD files refer to IED capabilities description files, should
File describes basic data model and the service of equipment offer）, the array format of its data output is not quite similar, such as double A/D
Channel sample, bus PT combining unit three-phase bus voltage can be according to the different arrangement lattice such as A-A, B-B, C-C or A-B-C, A-B-C
Formula is exported；
（2）The integrated manufacturer of different intelligent transformer substation system differs, and interior main transformer 110kV sides of standing, 110kV circuits, mother merge single
Equipment manufacturer is also not necessarily identical for unit and 110kV bus protections, observing and controlling, SV network switch etc., therefore, each intelligent station 110,000
Volt bus PT combining unit device SV, GOOSE configuration files are different.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art part, and providing one kind can temporarily access runtime,
Abnormal combining unit is substituted, for 110 kilovolts of main transformer protections, route protection, bus differential protection, record ripple, observing and controlling, meterings are provided in station
The bus secondary voltage of stabilization, portable mobile, can be used to substitute the abnormal 110 kilovolts of buses of intelligent substation of different generations
110 kilovolts of mobile bus PT combining units of the intelligent substation that PT combining units are used.
A kind of 110 kilovolts of mobile bus PT combining units of intelligent substation, include bus PT combining units and storage
Unit, it sets multiple ICD data models in conventional bus PT combining units, and each data model is carried out by selection key
Selection, in multiple different 110 kilovolts of bus PT combining units SV, GOOSE of intelligent substation of built-in storage unit memory storage
Configuration file, described SV, GOOSE configuration file is generated by different intelligent transformer station SCD integrated configurations instrument, and SV, GOOSE match somebody with somebody
Calling for file is put to be completed using selection key.
When I sections of bus PT combining unit device is extremely out of service in 110 kilovolts of I mother's bus equipment Intelligent control cabinets,
Accessing mobile bus PT combining units carries out loop replacement, specific as follows：
（a）Mobile bus PT combining unit input circuit wiring, by prefabricated cable by 110kV I, II section bus protection
Measurement, metering, opening voltage access mobile bus PT combining unit analog inputs loop；
（b）Mobile bus PT combining unit output loop wiring, by main transformer 110kV sides combining unit 1,110kV circuits, mother
Combining unit and each fiber optic cable interface transposing of 110kV bus protections, process layer SV network switch merge to mobile bus PT
The corresponding port of unit, now mobile bus PT combining units access system substitute and have dropped out the bus combining unit of operation
Device 1, for 110 kilovolts of main transformer protections in transformer station, route protection, bus differential protection, record ripple, observing and controlling, that metering provides bus is secondary
Voltage, ensures 110 kilovolts of system reliability services.
The explanation that several English are write a Chinese character in simplified form above：（1）IED is the abbreviation of intelligent electronic device.Refer to comprising one or more
Processor, is subjected to the data from external source, or sends data, or the device being controlled to outside, and such as numeral is protected
Shield, controller etc..
（2）SCD：Whole station CONFIG.SYS, this document is described between the exemplary configuration and messaging parameter, IED of all IED
Communication configuration and transforming plant primary system architecture, by the system integration, manufacturer completes.
（3）ICD：IED capabilities description files, system integration manufacturer is supplied to by device manufacturer, and this document describes IED offers
Master data model and service.
（4）CID：IED exemplary configuration files, CID files each device has one, by device manufacturer according in SCD file
This IED relevant configurations are generated.
（5）SV：That is sampled value, it is based on publish/subscribe mechanism, exchanges the correlation model of the sampled value that sampled data is concentrated
Object and service, and the mapping that these model objects and service are arrived between ISO/IEC 8802-3 frames.
（6）GOOSE：It is a kind of transformer substation case towards general object.It is mainly used in realizing being set in multiple smart electronicses
Information transmission between standby (IED), the multi-signal such as including transmission breaker tripping and closing, connection locking（Order）, it is general with high-transmission success
