Description
Technical field
The invention belongs to intelligent substation technical fields, more particularly to a kind of intelligent power transformation without global synchronization system
Station level bus network system.
Background technique
According to the description and requirement of 61850 substation communication network of IEC and system standard, intelligent substation comprehensive automation
The equipment of change system presses process layer, three layers of wall, station level layered arrangement according to its function.In the long term, substation network
Structure will divide three phases gradually to improve, i.e., ad hoc mode, process layer mode bus, process bus and station level bus merge
That is " station level bus " mode.
In intelligent substation network, core content is that the equipment such as wall protection supervisory equipment are needed to access device
Same interval or each phase voltage electric current across interval realize synchronous acquisition and processing, as route protection, main transformer protection, bus are protected
Shield is required to the sampling data synchronization of each input, and the synchronization of sampled data also seems for primary equipment fault identification and processing
It is particularly important.Due to being limited by sampled value networking simultaneous techniques maturity and stability, in current engineer application, adopt more
With station level MMS network, SV sampled value network, GOOSE network layering separate configurations scheme, sampled value transmission mostly uses a little pair
The mode that point is directly adopted, the scheme that GOOSE mostly uses point-to-point straight jump and network tripping to control and deposit；Wherein, it is based on global synchronization
Sampled value networking transmission and process layer bus schemes have a small amount of pilot application, not yet a large amount of engineering applications.
It is currently based on intelligent substation unification of three nets networking transmission plan such as Fig. 1 of global synchronization system, interior offer mark of standing
Punctual clock is outer synchronization system, receives GPS/ big-dipper satellite clock synchronization, is stood interior by global synchronization system, with optical fiber B code or IEEE
The clock synchronizations modes such as 1588, into station, the equipment such as sampled value sending device (combining unit) and protection supervisory equipment provide uniform pulse
Signal.Realize that the synchronization of data acquisition is synchronous with output based on uniform pulse signal between each sampled value output equipment, sampled value connects
Receiving unit is based on uniform pulse signal and carries out sampling reduction to sample values, by judging that the whether identical realization of packet number is adopted
The synchronization of sample value.Fig. 1 is substation's unification of three nets networking structure schematic diagram based on global synchronization system of the prior art.
Under the sampled value networking transmission mode based on outer synchronization system, sampled value output equipment sends message by unified arteries and veins
Rush the control of signal.When uniform pulse signal arrives, output equipment can be sent respective sampling value message in synchronization
Onto the network switch；Since single-channel sampling Value Data message flow is generally higher than 3Mb/s, sampled value output equipment interval compared with
When more, the transient data flow on interchanger single port is huge, easily leads to data forwarding and is lined up and generates biggish exchange
Machine Forwarding Delay, and Forwarding Delay length, by the random variations due of port flow, sampling data synchronization problem is more prominent, shadow
The stable operation of acoustic system.In addition, the sampling value synchronization reliability of system is by the reliable of globally unique outer synchronization system clock
Property determine, after outer synchronization system loses satellite clock synchronization, the accumulated error that synchronization system is generated using high stability crystal oscillator work, to adopting
The sample-synchronous of sample value output equipment and accuracy also have an impact.In addition, when outer synchronization system links disconnection or failure,
Entire sampling value synchronization system will be unable to work normally, and then influence the safe and stable operation of entire integrated system.
It is based on the measurable sampled value networking transmission plan of sampling value message transmission delay there are also a kind of at present, the program uses
Customized delay can test cross change planes, combining unit issue sampling value message enter interchanger when and message transfer friendship
When changing planes, unified timestamp (markers) is stamped in sampling value message, protection supervisory equipment passes in and out interchanger by message
Timestamp difference, sampling value message can be calculated by forwarding the delay Δ T of process on interchanger, so as to recall
It obtains the correct time that each interval sampling value message issues, and then obtains across the interval sampling data after synchronizing by interpolation.It should
Scheme uses nonstandard industrial switch: automatic identification sampling value message simultaneously only carries out sampled value to play timestamp processing；And
It destroys the integrality of IEC61850-9 sampling value message: in original sampling value message and not including timestamp information, the party
What case thought timestamp information is added in two reserved words of the message, so that the international standard nonstandardized technique, the mark of scheme
Quasi-ization degree obviously regresses, and versatility is not strong.
Therefore, the existing intelligence that networking is distinguished with station level network, sampled value network, GOOSE network in intelligent substation
Energy substation project application mode, needs secondary device quantity and external interface large number of, the network structure and optical fiber of system
Link configuration is complicated, and interior resource of standing can not be shared, and equipment development and engineering construction higher cost, transformation and enlarging are not easy.It is based on
The sampling value synchronization system of outer synchronization system relies on globally unique outer synchronized clock system, and operation stability is relatively poor.And
The message consistency of 61850 standard of IEC is destroyed based on the measurable sampling value synchronization scheme that is delayed, and is used customized
Nonstandardized technique industrial switch, the versatility and standardization level of scheme receive apparent restriction.These shortcomings,
The development of intelligent substation technology seriously is constrained, does not give full play of the technical advantage of 61850 international technical standards of IEC, nothing
Method meets the needs of future substation technology development.
