Description
Technical field
The invention belongs to intelligent substation technical field, more particularly to a kind of intelligent power transformation without global synchronization system
Station level bus network system.
Background technology
Description according to IEC 61850 substation communication network and system standard and requirement, intelligent substation comprehensive automation
The equipment of change system presses process layer, wall, three layers of layered arrangement of station level according to its function.In the long term, substation network
A point three phases is progressively improved by structure, i.e. ad hoc mode, process layer mode bus, process bus and station level bus merges
I.e. " level of standing bus " mode.
In intelligent substation network, core content is that the equipment such as wall protection supervisory equipment need to access device
Same interval or each phase voltage electric current across interval realize synchronous acquisition and process, as route protection, main transformer protection, bus are protected
Protecting the sampling data synchronization being required to each input, the synchronization of sampled data also seems for primary equipment Fault Identification and process
Particularly important.Owing to being limited by sampled value networking simultaneous techniques maturity and stability, in current engineer applied, adopt more
By station level MMS network, SV sampled value network, the scheme of GOOSE network layering separate configurations, it is a little right that sampled value transmission uses more
The mode that point is directly adopted, GOOSE uses point-to-point straight jump and network tripping operation control the scheme deposited；Wherein, based on global synchronization
Sampled value networking transmission and process layer bus schemes have a small amount of pilot to apply, not yet a large amount of through engineering approaches application.
It is currently based on intelligent substation unification of three nets networking transmission plan such as Fig. 1 of global synchronization system, mark is provided in standing
The i.e. outer synchronization system of punctual clock, when accepting GPS/ big-dipper satellite pair, passes through global synchronization system, with optical fiber B code or IEEE in standing
Mode during 1588 grade pair, in station, sampled value sends the equipment such as equipment (combining unit) and protection supervisory equipment and provides uniform pulse
Signal.Realize synchronization and the output synchronization of data acquisition between each sampled value output equipment based on uniform pulse signal, sampled value connects
Receiving unit carries out sampling reduction based on uniform pulse signal to sample values, by judging that the whether identical realization of packet number is adopted
The synchronization of sample value.Fig. 1 is the transformer station's unification of three nets networking structure schematic diagram based on global synchronization system of 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, respective sampling value message can be sent by output equipment at synchronization
On the network switch；It owing to single-channel sampling Value Data message flow is generally higher than 3Mb/s, is spaced relatively at sampled value output equipment
When many, the transient data flow on switch single port is huge, is easily caused data and forwards queuing to produce bigger exchange
Machine Forwarding Delay, and Forwarding Delay length is by the random variations due of port flow, sampling data synchronization sex chromosome mosaicism is more prominent, shadow
The stable operation of acoustic system.In addition, reliable by globally unique outer synchronization system clock of the sampling value synchronization reliability of system
Property determine, when outer synchronization system loses satellite pair after, synchronization system utilizes the accumulated error that high stability crystal oscillator work produces, to adopting
The sample-synchronous of sample value output equipment and the degree of accuracy also have an impact.In addition, when outer synchronization systematic connection disconnection or fault,
Whole sampling value synchronization system will be unable to normally work, and then affects the safe and stable operation of whole integrated system.
Also having a kind of based on sampling value message transmission delay measurable sampled value networking transmission plan at present, the program uses
Self-defining time delay can test cross be changed planes, when sampling value message that combining unit sends enters switch and message transfers friendship
When changing planes, all stamping unified timestamp (markers) in sampling value message, protection supervisory equipment passes in and out switch by message
The difference of timestamp, sampling value message can be calculated on switch, forward the time delay Δ T of process, such that it is able to backtracking
Draw the correct time that each interval sampling value message sends, and then draw across the interval sampling data after synchronization by interpolation.Should
Scheme have employed nonstandard industrial switch：Automatically identify sampling value message and only carry out to sampled value playing timestamp process；And
Destroy the integrality of IEC61850-9 sampling value message：Original sampling value message does not comprise timestamp information, the party
In two reserved words that timestamp information is added this message that case is thought so that this international standard nonstandardized technique, the mark of scheme
Quasi-ization degree substantially regresses, and versatility is not strong.
Therefore, existing with station level network, sampled value network, the intelligence of GOOSE network difference networking in intelligent substation
Energy substation project application mode, needs secondary device quantity and external interface large number of, the network structure of system and optical fiber
Link configuration is complicated, and in standing, resource cannot be shared, and equipment development and engineering construction are relatively costly, and transformation and enlarging are difficult to.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
Destroy the message uniformity of IEC 61850 standard based on time delay measurable sampling value synchronization scheme, and have employed self-defined
The industrial switch of nonstandardized technique, the versatility of scheme and standardization level receive significantly restriction.These weak points,
Seriously constrain the development of intelligent substation technology, do not give full play of the technical advantage of IEC 61850 international technical standards, nothing
Method meets the needs of future substation technology development.
