2. And selecting a signal point to be tested, and starting automatic test.
3. The testing system starts the following two services according to the IED information in the SCD file: firstly, enabling T61850_S to virtualize all local protection IP needing simulation, starting corresponding 61850 service, and waiting for M61850_C connection of an intelligent management unit; and secondly, enabling the T61850_C client to serve and connecting M61850_S of the intelligent management unit.
4. After the test system is successfully connected with M61850_C and M61850_S of the intelligent management unit, automatic test can be performed, and the test is divided into a remote control test, a remote measurement test and a remote signaling test. The following are examples.
Remote control test:
1. The HMI fetches a certain remote control signal in the database, for example, the fetch signal is: "remote control 5051 breaker" and set its value to 1 (close), then "ref+ value" of this signal, namely: the two messages of 'CB 5051CTRL/CSWI1$CO $Pos and 1' are sent to T61850_C, and the T61850_C forms an mms client message data frame according to the 'Ref+ value' information and then sent to the station control layer network. ( And (3) injection: the test flow is described herein only to simplify the selection and confirmation steps in the actual remote control process )
2. After receiving the mms client message data frame on the station control layer network, the M61850_S module of the intelligent management unit sends out the message data frame from the M61850_C module to the local protection private network after analysis, storage and conversion in the intelligent management unit.
3. After receiving the signal sent by the intelligent management unit from the local protection private network, the T61850_S end of the test system analyzes the signal into data of a Ref+ value, and then sends the data to the HMI.
4. The HMI compares the received Ref+ value with the Ref+ value of the signal extracted in the step 1, and the consistency is correct, otherwise, the HMI is wrong.
5. Setting the value of the extraction signal to 0 (opening), and repeating the steps 1-4.
Telemetry test:
1. the HMI fetches a certain telemetry signal in the database, for example, the fetch signal is: "5051 breaker a phase current" and set its value to 0.55A, then "ref+ value" of this signal, namely: the information of PB5051APROT/MMXU1$MX $A $ phsA and 0.55 is sent to T61850_S, and the T61850_S forms an mms server side message data frame according to the Ref+ value information and then sends the message data frame to an on-site protection private network.
2. After receiving the mms server message data frames on the local protection private network, the M61850_C module of the intelligent management unit sends out the mms server message data frames from the M61850_S module to the station control layer network after analysis, storage and conversion in the intelligent management unit.
3. After receiving the signal sent by the intelligent management unit from the station control layer network, the T61850_C end of the test system analyzes the signal into data of a Ref+ value, and then sends the data to the HMI.
4. The HMI compares the received Ref+ value with the Ref+ value of the extracted signal, if the received Ref+ value is consistent with the received Ref+ value, the received Ref+ value is correct, and if the received Ref+ value is not consistent with the extracted signal, the received Ref+ value is incorrect.
Remote signaling test:
1. The HMI extracts a certain remote signaling signal in the database, for example, the extracted signal is: "split-phase trip position TWJa", and set its value to 1 (combined position), then "ref+ value" of this signal, that is: the two information of PB5051A/PROT/GGIO17$ST & Ind1 and 1 are sent to T61850_S, and the T61850_S forms an mms server side message data frame according to the Ref+ value information and then sends the mms server side message data frame to an on-site protection private network.
2. After receiving the mms server message data frames on the local protection private network, the M61850_C module of the intelligent management unit sends out the mms server message data frames from the M61850_S module to the station control layer network after analysis, storage and conversion in the intelligent management unit.
3. After receiving the signal sent by the intelligent management unit from the station control layer network, the T61850_C end of the test system analyzes the signal into data of a Ref+ value, and then sends the data to the HMI.
4. The HMI compares the received Ref+ value with the Ref+ value of the extracted signal, if the received Ref+ value is consistent with the received Ref+ value, the received Ref+ value is correct, and if the received Ref+ value is not consistent with the extracted signal, the received Ref+ value is incorrect.
5. Setting the value of the extraction signal to 0 (minute), and repeating steps 1 to 4.
In addition, as the in-situ protection technology is rapidly developed, a network structure diagram of the intelligent management unit as shown in fig. 6 is also presented. The intelligent management unit is not connected with the station control layer network, but directly transmitted to the remote overhaul main station through IEC 103 protocol. Although this mode is different from fig. 1, the test technology of the intelligent management unit is basically the same as the test technology and the test flow of the intelligent management unit except that the up communication protocol is different (61850 protocol in fig. 1 and 103 protocol in fig. 6), so the test method and the test system of the invention are also suitable for the test of the intelligent management unit with the network structure.
The HMI end, the T61850_C end and the T61850_S end of the test system are completely decoupled, the mutual influence is avoided, and different test cases only need to be edited in the HMI, and are irrelevant to the T61850_C end and the T61850_S end. The test system can automatically complete the functional test of the intelligent management unit.
In addition, DL/T860 is a communication standard between the device of the station control layer and the device of the spacer layer in the transformer substation, and when it is applied to the communication between the intelligent management unit and the remote master station, it needs to be properly expanded according to the communication characteristics of the proxy mode. The method comprises the steps that communication between substation secondary equipment and a remote master station is achieved through an intelligent management unit, all physical IEDs in the substation are mapped into virtual IEDs of the intelligent management unit, a data model of the virtual IEDs is consistent with that of the physical IEDs, and all the virtual IEDs achieve data access service with a remote master station client side through the same IP address. The intelligent management unit proxy communication mode is shown in fig. 7.
