The invention is described in further detail below with reference to the accompanying drawings:
referring to fig. 1, in an embodiment of the present invention, a data communication detection method for an intelligent substation is provided, which can fully satisfy data communication detection of an autonomous controllable new-generation intelligent substation, and meanwhile, the method has the characteristics of simplicity, strong usability, strong operability, and the like, and is suitable for the fields of factory detection, product detection, field debugging, and the like of the autonomous controllable new-generation intelligent substation.
Specifically, the intelligent substation data communication detection method comprises the following steps:
s1: and acquiring test data and test parameters, generating an SCD (System configuration document) file of the intelligent substation according to the test parameters, and deploying the SCD file to a station-level computer of the intelligent substation.
Specifically, the test data and the test parameters may be obtained from a preset test sample library and a test parameter library. The test sample library is used for storing test data required by the test, wherein the test data can comprise one or more of a time-data sequence, report control block selection, remote control mode selection and journal control block selection. Specifically, the test sample library is provided with a plurality of test data models, and test data can be generated according to the test data models and stored in the test sample library for calling in a subsequent test process.
The test parameter library is used for storing parameters required by the test, the test parameters can include one or more of SV (periodic sampling value) message parameters, subscription and release network parameters of GOOSE messages (substation events facing general objects), channel parameters, sending period parameters, receiving period parameters, data change parameters of MMS (manufacturing message Specification) report control blocks, period trigger parameters, data update parameters, parameter configuration of total calls, parameter configuration of remote control modes, parameter configuration of log control blocks and configuration of data attributes in data sets, and the test parameter configuration is realized by selecting the test parameters.
The specific method for generating the SCD file of the intelligent substation according to the test parameters comprises the following steps: acquiring information model data of the intelligent substation, an ICD file of the intelligent substation and an SSD file of the intelligent substation; integrating an ICD file and an SSD file of the intelligent substation according to the information model data of the intelligent substation to obtain an initial SCD file of the intelligent substation; and configuring an initial SCD file of the intelligent substation according to the test parameters to obtain the SCD file of the intelligent substation.
Specifically, referring to fig. 2, the initial SCD file of the intelligent substation is obtained by combining an ICD file (intelligent electronic device description file) of the intelligent substation, an SSD file (system specification file) of the intelligent substation, and model data in an information model database of the intelligent substation. In one possible embodiment, a human-machine interface is provided to control the above-mentioned combining process, enable the invocation and combination of data, and enable IED configuration, the generation of CID files (instance configuration files), and the configuration of IED devices (intelligent electronic devices) to an intelligent substation.
S2: the method comprises the steps of obtaining the layers of devices to be tested of the intelligent substation, determining the excitation mode of test data according to the layers of the devices to be tested, and sending the test data to the devices to be tested in the excitation mode according to test parameters.
Referring to fig. 3, the specific method for determining the excitation mode of the test data according to the hierarchy of the device to be tested includes: when the hierarchy of the equipment to be tested is a process layer, the excitation mode of the test data is to adopt remote control or remote signaling hard node state control output excitation; when the hierarchy of the device to be tested is the spacer layer, the excitation mode of the test data is to start remote signaling excitation by adopting a GOOSE message; and when the to-be-tested equipment is in the station control layer, starting remote signaling excitation by adopting an MMS report.
Specifically, because the data input and output formats of each layer of the process layer, the bay layer and the station control layer of the intelligent substation are different, the test excitation modes adopted during the test are also different. For equipment in a process layer, remote control or remote signaling hard node state control output excitation is adopted, namely, a state quantity remote signaling output mode is adopted for excitation; for the equipment of the spacer layer, starting remote signaling excitation by adopting a GOOSE message, namely outputting excitation through the GOOSE message; for the equipment of the station control layer, remote signaling excitation is started by adopting an MMS report, namely, excitation is output through the MMS report. The process layer generally comprises a merging unit and an intelligent terminal, the spacer layer generally comprises a measurement and control device and a protection device, and the station control layer generally comprises a data server, a monitoring host, a data communication gateway machine and a comprehensive application server.

The specific method for receiving the feedback message of the device to be tested to the test data is as follows: and receiving a feedback message of the device to be tested to the test data in a bypass mode of the mirror image of the port of the switch.
Specifically, for different devices to be tested, the output data formats of the devices to be tested are different, and in order to adapt to these output modes, and since the outputs of the devices to be tested are all digital signals, in this embodiment, the outputs of the devices to be tested are obtained in a bypass mode of an image of an interface of the switch, that is, the feedback signals of the devices to be tested to the test data, and then the feedback messages of the devices to be tested to the test data are extracted from the feedback signals, and particularly for connection-oriented signals, the following steps are performed: MMS, 104, etc., such a bypass mirror message is an efficient way.
After obtaining a feedback message of the device to be tested for the test data, in order to ensure that the data sent and received in the test process can be matched, a specific process of analyzing the configuration of the message parameters by importing the SCD file is as follows: analyzing a feedback message of the device to be tested to the test data through the SCD file; time encapsulation and data message separation in the feedback message are carried out through analysis, then unpacking analysis is carried out according to different types of messages, and the calibration time in the feedback message is analyzed to obtain an analysis result.
In a possible implementation manner, when receiving a feedback packet of the device to be tested for the test data, the feedback packet of each output port of the device to be tested for the test data is received, and time calibration facing the output port is performed on each feedback packet.
Specifically, because the device to be tested includes a plurality of layers, the remote signaling test adopts the following mode: the source end inputs a multi-port interception mode, namely, only the input end of the device to be tested applies test excitation, but message interception is carried out on each output port of the whole device to be tested, and meanwhile, port-oriented time calibration is carried out on intercepted messages so as to determine the time of the messages reaching each port. The time calibration in the test can be absolute time (time calibration by a standard clock source) or relative time (time calibration by a test system).
And then, obtaining a data communication detection result of the intelligent substation according to the message analysis result and the test data. Specifically, according to the message analysis result and the test data, the correctness and the delay characteristic of the whole test are analyzed in combination with the calibration time, and the data communication detection result of the intelligent substation is obtained. For example: when the correctness and the delay characteristic of the whole test meet the preset requirements, the data communication detection of the intelligent substation is passed; otherwise, the intelligent substation data communication detection is not passed.
In a possible implementation mode, 10 times of telecommand displacement data are compiled according to a whole second time sequence and stored in a test sample case base as test data, and then the intelligent substation data communication detection method is adopted for testing. In the testing process, the testing data is selected from the testing sample library, the level of the intelligent substation to-be-tested equipment is obtained, the excitation mode of the testing data is determined according to the level of the to-be-tested equipment, the testing data is applied to the input port of the to-be-tested equipment in the excitation mode, then the output of the to-be-tested equipment is received, the message is analyzed, information such as remote signaling state, change times and change time is recorded, and the information is compared with the testing data to obtain a testing result, if: if the 10 times of displacement information are consistent, the test result is qualified, and if the displacement information is inconsistent, the test result is unqualified. By the testing mode, the testing of the remote signaling correctness and the testing of the remote signaling delay time can be completed, and the remote signaling trigger interval of the testing data can be changed into 1ms, so that the testing of the SOE resolution can be realized.
In summary, according to the data communication detection method for the intelligent substation, the SCD file of the intelligent substation is generated according to the test parameters and is deployed to the station level computer of the intelligent substation, different test parameters can be designed according to different requirements based on configurability of the test parameters, data communication detection of the intelligent substation with different requirements is realized, and then correctness and delay characteristics of data communication of the intelligent substation in different operation modes are detected. And the configuration of the SCD file can fully meet the data communication detection requirement of the autonomous controllable new-generation intelligent substation designed aiming at a specific network architecture and an information model, and meanwhile, the excitation mode of test data is determined according to the level of the equipment to be detected, so that the detection of the equipment to be detected at different levels is realized.
