The technical scheme of the application is described in detail in detail with reference to specific embodiment：

1 configuration file SCD analytic methods

Intelligent substation SCD configuration files include header, substation, communication, ied and The parts of template five.Wherein header describes the information of FileVersion, author etc；Substation describes transformer station The structure of primary system；Described in communication parts transformer station station level mms networks, process layer goose networks with And the messaging parameter of the related secondary device of process layer sv networks, by parsing the contents of the section, can obtain every primary network station The access point ConnectedAP and its mailing address of associate device, the IP address of equipment station level interface or process layer interface MAC Address, APPID and vlan information.

In the IED parts of SCD file, all smart machines for participating in communication, such as protection device, observing and controlling in station are described Device, combining unit, intelligent terminal etc..There are network access point, such as station level network access point under the server fields of IED S1, process layer GOOSE network accessing points G1, process layer SV accessing points M1.It is fixed under the S1 accessing points in the LLNO of each logical device The data set that justice device sends to clients such as monitoring or scheduling systems.Under the G1 accessing points in the LLN0 of each logical device, Define the GOOSE data sets (if having) that device is externally issued；Under the M1 accessing points in the LLN0 of each logical device, dress is defined Put the SV data sets (if having) of external issue.

After SCD is parsed, each IED attribute and its link with other associate devices, empty loop information collection are obtained, As the foundation that software simulation IED runs.

2IED communication simulations

Here the correctness in empty loop being test equipment the emulation purpose of smart machine IED, therefore need not be related to The functional characteristic of equipment, such as protection act logic, and it is primarily upon communications portion.

The emulation of IED follows IEC61850 Communication Protocol Models, and the communication standard slave unit model, abstract communication service connect The aspect such as mouth, data structure and attribute, particular communication service mapping comes specification substation communication network and system.IED models are needed Completely to embody production, encapsulation, transmission, the overall process of parsing of information.

IED emulation can be divided into combining unit, intelligent terminal, protection device, measure and control device, monitoring system according to device type Deng；According to communication message type, SV emulation, GOOSE emulation and MMS emulation can be divided into.

For different type equipment, such as observing and controlling, protection are required for emulating GOOSE and MMS；Combining unit needs to emulate SV And GOOSE.Therefore facility center management is not introduced here, and is divided into the part of SV, GOOSE, MMS tri- according to type of message and is situated between Continue emulation mode.

2.1 SV are emulated

SV sampling value messages are generated according to certain rule by combining unit, and combining unit is electronic mutual inductor and guarantor The key equipment of the secondary device interfaces such as shield, observing and controlling and record ripple, it receives and processes three-phase current and three-phase voltage signal simultaneously, After by multiple signals synchronization, used to secondary device according to IEC61850-9-2 standard outputs.

The sample frequency of SV messages is 4000Hz in actual transformer station, i.e., 80 points of being sampled per cycle, message sends interval It is 250us (250us ± 10us).Here because only needing to verify the correctness in empty loop, therefore between simulation frequency and time Every without requirement.

SV messages use osi model in transmission over networks, but only use four layers in seven layers of OSI network model, Application layer, expression layer, data link layer and physical layer, transport layer and Internet are sky.Application layer defines protocol Data Unit PDU, by after expression layer coding, not using ICP/IP protocol, but map directly to data link layer and physical layer.It is this to reflect The purpose for penetrating mode is to avoid communication stack from causing transmission delay, so as to ensure message transmissions, the rapidity for the treatment of.

SV simulation processes are：According to the MAC Address of SV, APPID, number of channels, the data object of passage, data in SCD Type etc. is configured, and organizes 9-2 messages, and send to data/address bus according to certain intervals.The form for emulating message is as shown in Figure 2.

The explanation of critical field in message：

MAC Address：Multicast address；01-0C-CD-04 starts；Unique mark,

Ethernet type：SV is 0x88BA,

APPID：Two after unique mark, generally destination address,

Synchronous mark：Put 1 explanation sampled value be it is synchronous,

Maintenance mark：The position 1 when throwing maintenance state,

Sampling channel time delay：The constant time lag of combining unit output is collected from transformer,

Number of active lanes：Defined by configuration file.

2.2 GOOSE are emulated

Use data set total in transformer station process with GOOSE that " publish/subscribe " mode carries out common data exchange It is used for breaker tripping and closing order and the quick transmission of status information on route, it works in ethernet link layer, directly serving in should With devices such as layer protection and observing and controlling.

In intelligent substation, GOOSE communicates between bay device and process layer intelligent cell correctness and reliability Property it is all extremely important, it is desirable to GOOSE publish/subscribes configuration must be correct.Therefore, not only need to check two in SCD models Whether secondary logical circuit line is consistent with designing institute drawing, in addition it is also necessary to carry out GOOSE communication tests, that is, simulate GOOSE and issue/order Read, whether normal issue with the GOOSE for testing each equipment, whether simulation GOOSE issues test equipment function normal etc..Here adopt The correctness that GOOSE is configured is verified with GOOSE simulation softwares.

GOOSE message emulation is needed according to the MAC Address of GOOSE in SCD, GoID, dataset, number of channels, passage Data object, data type etc. are configured, and organize message, and send to data/address bus according to certain intervals.GOOSE message frame structure As shown in Figure 3.

GOOSE message significant field is parsed：

MAC Address：Multicast address；01-0C-CD-01 starts；Unique mark,

Ethernet type：GOOSE is 0X88B8,

APPID：Important sign, it is typically identical with two after target MAC (Media Access Control) address,

GoCbRef：Goose control blocks quote path,

DataSet：Data set quotes path,

GoID：Important mark,

Test：Maintenance position；The mark for whether using,

SqNum：GOOSE conjugates the message number for sending so far for the last time,

StNum：GOOSE message displacement number of times altogether,

dataSet：Number, order, the data type of data set, wherein data item are all by the GOOSE data of configuration file Collection definition.Four types of GOOSE parameters in data set,

Boolean type：0th, 1 two states, regular tap amount signal,

Bit string type, 01,10,00,11 4 kind of state, for represent switch, disconnecting link two-position signal；01 expression point；10 tables Show conjunction；00 represents centre position；11 represent that position is invalid,

Time type, represents the utc times of data displacement,

Floating type, for transmitting the analog acquisition signal such as temperature.

2.3 MMS are emulated

MMS emulation mainly uses software to realize IEC61850 client functionalitys.IEC61850 clients refer to based on mark Certainly adopted client/server communication pattern carries out the system and equipment of function access and information exchange with bay device, such as Monitoring system, telemechanical and substation etc., client follow IEC61850-8-1, that is, be mapped to MMS standards, are carried out with bay device Communication.Bay device is server end.

IEC61850 client functionalitys mainly include communication association, report treatment, remote control, definite value operation, record ripple calling etc..

MMS emulation is exactly to develop general 61850 client, is associated with equipment, performs total greeting, receives service end master The operations such as report, file calling, definite value calling download, the remote control sent on dynamic, between true imitating substation station level equipment Communication process.

3 empty loop verifications

Empty loop verification process is carried out in the subscriber of communicating pair.Subscriber such as SV messages is protection device or survey Control device.Then protection device then starts protocol monitor and authentication module, the received sv reports of detection after SV messages are received Whether text is object that oneself is subscribed to, and whether the specific field of message meets SCD definition.

Each simulation IED includes empty loop verification module.As long as receiving message, whether just message configuration is just checked Really, whether frame format is correct etc..Some common message error types have following several：

(1) message format mistake, such as SV, GOOSE, MMS message format mistake；

(2) message is discontinuous, such as frame losing, repetition, time-out；

(3) data attribute change, such as quality factor change, synchronous mark change；

(4) SV samplings are abnormal, and such as frequency is unstable, and double A/D is inconsistent etc.：

(5) Changing Pattern of GOOSE StNum and SqNum, such as conjugates, restarts, state is empty becomes；

(6) configure inconsistent with SCD, such as data set, entry number, address, reference；

(7) ACSI service analyses, such as name resolving, data parsing, service process parsing, capture time, negative response.

By the detection of empty loop verification module, the process of simulation manual signal transmission, so as to realize empty loop-around test.

The method that the application is proposed can be applied in intelligent substation, according to the signal imitation transmission of this method exploitation System, after system reads SCD configuration files, corresponding virtual IED is generated according to the IED quantity and communication function that are configured in SCD. After test process starts, emulation testing is carried out to each IED one by one, by the verification of the communication message to the IED, check IED Between empty loop it is whether correct.Using the simulation transmission system of empty loop test method of the invention, can effectively find that SCD matches somebody with somebody The mistake in middle empty loop is put, with practical value.

The operation principle of signal imitation transmission system is as follows：(1) configuration file of redaction is read, each IED is parsed Empty terminal.(2) automatic or manual mode selects the IED for needing to be tested, generally pairwise testing.(3) wherein one is simulated Individual IED sends message, may be SV, GOOSE or MMS message, and another IED receives message, and judges whether it is that oneself is subscribed to Information and type, provide alarm if mistake, point out the mistake of configuration file appropriate section.System can be while Multipexer SV With GOOSE, the automated procedures of test are improved, improve operating efficiency, reduce the generation of human error.
