The scheme needs to configure a special tester client, and the client needs to write complex software for realizing the test function.
Generally, at present, a physical closed-loop network is generally required to be formed in the IEC61850 consistency automatic test, or a closed-loop network is formed by simulating GOOSE/SMV signals through a test client, so that not only is the requirement on hardware for auxiliary test higher, but also the software design is more complex, and the engineering implementation is not facilitated.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings and examples, but the embodiments of the present invention are not limited thereto.
The second IEC61850 version defines Common Service Tracking (CST), which inherits the attribute of CST and adds its own proprietary attribute to form a Service Tracking class.
The intelligent substation IEC61850 consistency test method disclosed by the invention has the flow as shown in FIG. 1, and the method utilizes the service tracking class to construct a service tracking model, completes logic closed-loop automatic test by cooperating with service tracking based on an IEC61850 protocol MMS, monitors service operation during service operation and verifies the service operation result, thereby realizing automatic test of protocol consistency of the intelligent substation.
The method is described in detail below.
Firstly, a service tracking model is established according to the service tracking class. The service tracking model includes information about a certain service, such as the object of a service operation, the value of the object of the operation, the service result, the cause of an error, and the like. The step of establishing the service tracking model comprises the following steps:
1) defining a service tracking model;
2) configuring a service tracking model into a data set dedicated to service tracking;
3) a report control block or log control block is configured to control the set of data dedicated to service tracking.
Next, a service tracking model is added to an equipment model configuration file (ICD) of the device under test.
Then, the ICD file is imported by using a system configuration tool, and an SCD file is generated.
And finally, the IEC61850 client analyzes the SCD file, extracts a service list needing to be verified, subscribes a report or log of a service tracking data set according to the service list, and performs service operation on the equipment one by one in an MMS mode. And the IEC61850 client judges the test result according to the service operation result of the tested equipment. The results of the service operations are actively uploaded to the IEC61850 client by the reporting service or stored in a log for the IEC61850 client to query.
In addition, the service tracking model can be expanded according to requirements on the basis of meeting the IEC61850 protocol definition; moreover, the service tracking model can be configured to a data set special for service tracking, and can also be stored in different data sets, so that the application range is wide, and the expandability is strong.
Moreover, the IEC61850 client does not need a special client, and the intelligent substation monitoring or remote motivation can be used as a test client.
According to the difference of data objects, the service that the service tracking class logical node (LTRK) can track is divided into three classes: control type service tracking, including all control-related services such as Select, Operate, Cancel and the like; control block type service tracking, including GetBARCALLVALUES, SetBARCALLUALUES and other services related to the control block; the public class service tracking comprises all other services such as Association, GetFile, GetServerDirectory and the like.
The following description will be given by taking control class service tracking as an example, as shown in fig. 2.
First, a service tracking model is added to the ICD file of the device under test. The specific establishment of the model is illustrated by taking integer control (INC) as an example, as follows:
1) define DOType for CTS, id int32CTS, as shown in FIG. 3.
2) The control service tracking model is instantiated in the remote control corresponding LN, with int32CTS quoted in ATCC, as follows:
3) the service tracking model information is configured into a data set special for service tracking, and the data set is named as Setting _ SR, and the following steps are carried out:
4) adding a report control block or log control block dedicated to service trace, the report control block being rcb _ service _ track, whose attribute datSet value is configured as the data set Setting _ SR defined above, for controlling the service trace data set Setting _ SR, as follows:
then, the ICD file is imported by using a system configuration tool, and an SCD file is generated.
And finally, the IEC61850 client program analyzes the SCD file and is connected with the equipment. The IEC61850 client subscribes to the report control block rcb _ service _ track.
As shown in table 1, the IEC61850 client sends control services to the device under test according to the service list, as shown in the first column of the following table, the service operation result is included in the rcb _ service _ track upload report, as shown in the second column of the following table, the client compares the service list with the service operation result, and the comparison result is shown in the third column of the following table.
TABLE 1
Other service test and verification methods are similar to the test and verification method of the integral remote control, and the flow is basically consistent. And the client side performs operation verification on each service one by one according to the SCD configuration file.
The invention also provides an IEC61850 consistency test system of the intelligent substation, which comprises an IEC61850 client and a system configuration tool; the system configuration tool is used for generating an SCD file according to the imported ICD file; the IEC61850 client is used for analyzing the SCD file, extracting a service list needing test verification, and performing service operation on the tested equipment in an MMS mode; the IEC61850 client extracts a service operation result according to the returned report or log of the service tracking data set and judges the consistency of the service operation result; the ICD file generation process comprises the following steps: and establishing a service tracking model according to the service tracking class, configuring a service tracking data set and generating an ICD file.
The core of the system is to realize the method for testing the IEC61850 consistency of the intelligent substation, and the description of the method is clear enough, so the system is not described any more.
While the present invention has been described in detail with reference to the preferred embodiments, it should be understood that the above description should not be taken as limiting the invention.
