Preliminary classification is first carried out to type of message according to MMSPDU type, type of message includes and is not limited to request, respond, connect etc.；
Then it is mapped to specific service type, service type includes and is not limited to reading and writing, directory service etc.；Finally according to
Specific service is mapped to ACSI protocol layer service by IEC61850-8-1 standard.
Step 3 judges whether there is the model information to match with ACSI protocol layer, if it is, then obtained from model
The associated description information of logical device, logical node, data set, data object etc.；There is no correlations to retouch if not or in model
Logical device, the logical node, data set, number stated information, then obtain ACSI protocol layer using IEC61850 engineering equipment model
According to the associated description information of object etc..
Step 4, according to the service of ACSI protocol layer and the description information of service object, realize the behaviour to project operation layer
Make, the deep analysis of SOE, intuitively shows the deep analysis result information of IEC61850 project operation layer.Specifically, it is abstracted logical
The SCL information model of telecommunications services interface ACSI according to the intelligent electronic device to match, in conjunction with IEC61850 engineering equipment model,
It is then that ACSI protocol layer is specific comprehensively to reflect customized and standard description information in current IED model
Service and service object be mapped to the operation, operating process and operation object of project operation layer.For example, the band value selection of ACSI
Service, object is that TEMPLATECTRL/CSWI1 $ CO $ Pos $ SBOw, ctlVal value is false, is mapped to operation layer are as follows: control
The control of 1st tunnel disconnecting switch of logical device processed point operation.
As shown in Fig. 2, being parsing result schematic diagram of the message deep analysis to IEC61850 project operation layer, right side is
MMS data packet source code obtains mobile agent server protocol layer details by wireshark protocol analysis library, from the figure, it can be seen that report
The mobile agent server protocol layer for accusing service mainly contains the letter such as VariableAccessSpecification, ListOfAccessResult
Breath, wherein the value of the primary variables in report services is contained in ListOfAccessResult, these values are standardized according to MMS
With IEC61850 Standard Map into ACSI protocol layer.As shown in the figure, ACSI protocol layer is to report ID, option field, sequence sequence
Number, entry time, dataset name, configuration version, bit string, data etc. are mapped one by one.In ACSI protocol layer, variable name
Although claiming and value being more clear than mobile agent server protocol layer entry, its content shown is still more abstract, needs more rich professional knowledge
It could understand with business experience.In project operation layer, logical device, object oriented and its value and report of service are clearly demonstrated
Reason is sent on announcement, can be summarized are as follows: data variation occurs for the first via bus AB phases line voltage of three-phase measuring device, after variation
Value is 34.09998.It is apparent that the information of project operation layer is more visual and clear, should be readily appreciated that.
