The invention is described in further detail below with reference to the attached drawing figures:
referring to fig. 1, in an embodiment of the invention, a method for detecting data communication of an intelligent substation is provided, which can fully satisfy the data communication detection of an autonomous controllable new-generation intelligent substation, and has the characteristics of simple method, 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 the test data and the test parameters, generating an SCD file (system configuration 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 obtained test data and test parameters may be obtained from a preset test sample library and test parameter library. The test sample library is used for storing test data required by a test, wherein the test data can comprise one or more of time-data sequences, report control block selection, remote control mode selection and log 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 the subsequent test process.
The test parameter library is used for storing parameters required by a test, wherein the test parameters can comprise one or more of SV (periodic sampling value) message parameters, network parameters of subscription and release of GOOSE messages (general object oriented substation events), channel parameters, sending periodic parameters, receiving periodic parameters, data modification parameters of MMS (manufacturing message specification) report control blocks, periodic trigger parameters, data updating parameters, parameter configuration of a general call, parameter configuration of a remote control mode, parameter configuration of a log control block and configuration of data attributes in a data set, 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 an intelligent substation, an ICD file of the intelligent substation and an SSD file of the intelligent substation; according to the information model data of the intelligent substation, integrating an ICD file and an SSD file 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, an 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 implementation, a human-machine interface is provided to control the above-described combining process, enable invocation and combining of data, and enable IED configuration, CID file (instance configuration file) generation and configuration to IED devices (intelligent electronic devices) of the intelligent substation.
S2: and acquiring the hierarchy of the equipment to be tested of the intelligent substation, determining an excitation mode of the test data according to the hierarchy of the equipment to be tested, and transmitting the test data to the equipment to be tested according to the test parameters in the excitation mode.
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 is as follows: 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 layer of the equipment to be tested is a spacer layer, the excitation mode of the test data is to start remote signaling excitation by adopting a GOOSE message; when the hierarchy of the equipment to be tested is a station control layer, the excitation mode of the test data is to start remote signaling excitation by adopting MMS report.
Specifically, because the formats of each layer of data input and output of the process layer, the spacer layer and the station control layer of the intelligent substation are different, the test excitation mode adopted during the test is also required to be different. For the equipment of the 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 equipment of a spacer layer, a GOOSE message is adopted to start remote signaling excitation, namely, excitation is output through the GOOSE message; for the equipment of the station control layer, the MMS report is adopted to start remote signaling incentive, namely the incentive is output through the MMS report. The process layer generally comprises a merging unit and an intelligent terminal, the spacer layer generally comprises measurement and control equipment and protection equipment, and the station control layer generally comprises a data server, a monitoring host, a data communication network shutdown and a comprehensive application server.

The specific method for receiving the feedback message of the equipment to be tested to the test data comprises the following steps: and receiving a feedback message of the equipment to be tested on the test data in a bypass mode of the port mirror image of the switch.
Specifically, for different devices to be tested, the output data formats are different, in order to adapt to the output modes, and because all the output data of the devices to be tested are digital signals, in this embodiment, the output of the devices to be tested is obtained through a bypass mode of the switch port mirror image, that is, the feedback signal of the devices to be tested to the test data, and further, the feedback message of the devices to be tested to the test data is extracted from the feedback signal, especially for the connection-oriented signals, such as: MMS and 104, etc., such bypass mirror messages are an efficient way.
After obtaining a feedback message of the device to be tested on the test data, in order to ensure that the data sent and received in the test process can be matched, the specific process of analyzing the configuration analysis of the message parameters by importing the SCD file is as follows: analyzing a feedback message of the equipment to be tested to the test data through the SCD file; and (3) splitting time encapsulation and data messages in the feedback messages through analysis, and then unpacking and analyzing according to different types of messages, and analyzing the calibrated time in the feedback messages to obtain an analysis result.
In one possible implementation manner, when receiving feedback messages of the device to be tested on the test data, receiving feedback messages of each output port of the device to be tested on the test data, and performing time calibration for each feedback message facing to the output port.
Specifically, since the device to be tested includes multiple layers, the remote signaling test adopts the following modes: the method comprises the steps that a source end inputs a multi-port interception mode, namely test excitation is only applied to an input end of equipment to be tested, message interception is conducted on each output port of the whole equipment to be tested, meanwhile, port-oriented time calibration is conducted on intercepted messages, and therefore time when the messages reach each port is determined. The time scale under test may be absolute time (calibrated by a standard clock source) or relative time (calibrated by a test system).
And then, according to the message analysis result and the test data, obtaining the data communication detection result of the intelligent substation. Specifically, according to the message analysis result and the test data, the accuracy and the time 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 time delay characteristic of the whole test meet the preset requirements, the intelligent substation data communication detection is passed; otherwise, the intelligent substation data communication detection is not passed.
In one possible implementation mode, 10 times of remote signaling deflection data are compiled according to the whole second time sequence, stored as test data into a test sample library, and then tested by adopting the intelligent substation data communication detection method. In the testing process, selecting the test data from a test sample library, acquiring the level of the equipment to be tested of the intelligent substation, determining the excitation mode of the test data according to the level of the equipment to be tested, applying the test data to an input port of the equipment to be tested in the excitation mode, then receiving the output of the equipment to be tested, analyzing a message, recording the information such as remote signaling state, change times and change time, and comparing the message with the test data to obtain a test result, such as: and if the 10-time deflection information is consistent, the test result is qualified, and if the 10-time deflection information is inconsistent, the test result is unqualified. Through the testing mode, the testing of remote signaling correctness and the testing of remote signaling delay time can be completed, the remote signaling triggering interval of the testing data can be changed into 1ms, and the testing of SOE resolution can be realized.
In summary, according to the intelligent substation data communication detection method, 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 the configurability of the test parameters, the intelligent substation data communication detection of different requirements can be realized, and the accuracy and the time delay characteristic of the intelligent substation data communication under different operation modes are further detected. And the autonomous controllable new-generation intelligent substation designed aiming at a specific network architecture and an information model can fully meet the data communication detection requirement of the autonomous controllable new-generation intelligent substation through the configuration of SCD files, and meanwhile, the excitation modes of test data are determined according to the layers of the equipment to be tested, so that the detection of the equipment to be tested in different layers is realized.
