Description

Local protection intelligent management unit testing method and device

Technical Field

The present invention relates to the technical field of testing a local protection intelligent management unit, and in particular to a testing method and device for a local protection intelligent management unit.

Background technique

The local protection intelligent management unit (hereinafter referred to as the "intelligent management unit") is an important device in the local protection system. Its function is to intelligently manage the local protection device, integrate the information of each sub-machine of the component protection, and realize the information interaction between the station control layer equipment and the local protection through the proxy service. The network structure diagram of the intelligent management unit in the substation is shown in Figure 1.

The three networks of SV/GOOSE/MMS in the station are integrated into a protection network. The intelligent management unit is connected to the protection network to obtain protection data, and at the same time connects to the station control layer MMS network to transmit protection data to other station control layer devices.

The networking mode of local protection at the station end is different from the ordinary protection of the smart substation. Ordinary protection is directly connected to the station control layer MMS dual network at the station end, and the station control layer equipment directly obtains protection information from the station control layer network (as shown in the networking mode of the measurement and control equipment in Figure 1). The local protection forms a protection dedicated network and is connected to the intelligent management unit. The intelligent management unit is connected to the protection dedicated network to obtain protection data, and at the same time connects to the station control layer MMS network to transmit the protection data to other station control layer devices. That is, the intelligent management unit is connected between the local protection dedicated network and the station control layer MMS network, playing a connecting role.

The functions of the intelligent management unit are divided into basic functions and advanced functions. The basic functions include the realization of centralized interface display, operation management, backup management, information storage, fault information management, and remote functions of the local protection devices in the substation. The advanced functions include automatic generation of main wiring diagrams, relay protection operation inspections, load tests, and automatic configuration of the process layer. For local unprotected installation of relay protection devices, intelligent management units must be configured, but there is currently a lack of technology for testing intelligent management units.

In a specific embodiment of the present invention, the function of the intelligent management unit in the local protection simplified network is shown in Figure 3. Since the local protection is the 61850 server, and the monitoring and telecontrol are the 61850 clients, the intelligent management unit is the 61850 client M61850_C downward, communicating with each local protection; and is the 61850 server M61850_S upward, communicating with the monitoring and telecontrol.

According to the functions and characteristics of the intelligent management unit, the intelligent management unit testing system (hereinafter referred to as the testing system) of the present invention using the local protection intelligent management unit testing method can automatically test the functions of the local protection intelligent management unit.

The test system of the present invention can simulate monitoring, telecontrol, and multiple protection devices to communicate with the intelligent management unit under test, send stimulus messages according to certain test rules, and then judge the action behavior of the intelligent management unit, so as to detect whether the function of the intelligent management unit is correct. As shown in Figure 4.

The test system consists of three parts: human-machine interface (HMI), 61850 client simulation module (T61850_C) and 61850 server simulation module (T61850_S). These three parts are independent of each other and do not affect each other. They communicate and work together through custom communication protocols.

The test system is connected across the station control layer network and the local protection dedicated network. The T61850_C module simulates the communication between the monitoring and telecontrol system and the M61850_S part of the intelligent management unit. The T61850_S module simulates the communication between the local protection device and the M61850_C part of the intelligent management unit. The HMI uniformly dispatches the T61850_C module and the T61850_S module, accepts the control instructions of the testers, and realizes advanced functions such as the generation of test cases and the determination of test results.

The test system mainly consists of the following parts as shown in Figure 5, where the optional models of each part are marked in brackets:

1. Human-computer interaction and display part: touch display screen to realize HMI human-computer interaction and interface display;

2. Data storage part: It is composed of SD memory card, DDR memory and EEPROM memory, which realizes the storage function of external data such as SCD files and internal data such as test system software programs, configuration files, etc.

3. Input and output interface part: USB interface, to realize the import of external data such as SCD files, and the output of test results such as test reports.

4. CPU part: CPU chip, runs the Linux operating system and serves as the operating platform for the test system software.

5. Communication interface: including the station control layer Ethernet interface and the protection private network Ethernet interface, which is the data exchange interface with the intelligent management unit of the measured object. Among them, the FPGA chip is added to the CPU chip and the Ethernet chip, the purpose is to process a large amount of communication data in real time, and to accurately guarantee the timing of communication messages, while reducing the burden of the CPU when performing complex algorithm calculations.

Specific test process example:

1. The test system reads the SCD file from the HMI, generates a data table of all test signal points in the internal database, and stores them according to remote control, telemetry and telesignaling. The data table is shown in Table 1.

Table 1

2. Select the signal point to be tested and start automatic testing.

3. The test system starts the following two services according to the IED information in the SCD file: First, let T61850_S virtualize all the local protection IPs that need to be simulated, and start the corresponding 61850 service, waiting for the connection of M61850_C of the intelligent management unit; second, let the T61850_C client service start to connect to M61850_S of the intelligent management unit.

4. After the test system is successfully connected to the M61850_C and M61850_S of the intelligent management unit, the automatic test can be carried out. The test is divided into three categories: remote control test, telemetry test and remote signal test. The following are examples to illustrate each.

Remote control test:

1. HMI takes out a remote control signal from the database, for example, the signal is: "Remote control of 5051 circuit breaker", and sets its value to 1 (closing), and then sends the "Ref+value" of this signal, that is, "CB5051CTRL/CSWI1$CO$Pos and 1" to T61850_C. T61850_C forms the MMS client message data frame according to the "Ref+value" information, and then sends it to the station control layer network. (Note: This is just to describe the test process, simplifying the selection and confirmation steps in the actual remote control process)

2. After the M61850_S module of the intelligent management unit receives the MMS client message data frame on the station control layer network, it is analyzed, stored and converted inside the intelligent management unit and then sent from the M61850_C module to the local protection dedicated network.

3. After receiving the signal from the intelligent management unit from the local protection dedicated network, the T61850_S end of the test system parses it into "Ref+value" data and then sends it to the HMI.

4. HMI compares the received "Ref+ value" with the "Ref+ value" of the signal taken out in step 1 above. If they are consistent, it is correct, otherwise it is an error.

5. Set the removal signal value to 0 (open) and repeat steps 1 to 4.

Telemetry Test:

1. HMI takes out a telemetry signal from the database, for example, the signal is: "5051 circuit breaker A phase current", and sets its value to 0.55A, and then sends the "Ref+value" of this signal, that is, "PB5051APROT/MMXU1$MX$A$phsA and 0.55" to T61850_S. T61850_S composes the MMS server message data frame according to the "Ref+value" information, and then sends it to the local protection dedicated network.

2. After the M61850_C module of the intelligent management unit receives the MMS server message data frame on the local protection private network, it is analyzed, stored and converted inside the intelligent management unit and then sent from the M61850_S module to the station control layer network.

3. After receiving the signal from the intelligent management unit on the station control layer network, the T61850_C end of the test system parses it into "Ref+value" data and then sends it to the HMI.

4. HMI compares the received "Ref+ value" with the "Ref+ value" of the taken signal. If they are consistent, it is correct, otherwise it is an error.

Remote signal test:

1. HMI takes out a telesignal signal from the database, for example, the signal is: "phase trip position TWJa", and sets its value to 1 (closed position), and then sends the "Ref+ value" of this signal, that is, "PB5051A/PROT/GGIO17$ST&Ind1 and 1" to T61850_S. T61850_S composes the MMS server message data frame according to the "Ref+ value" information, and then sends it to the local protection dedicated network.

2. After the M61850_C module of the intelligent management unit receives the MMS server message data frame on the local protection private network, it is analyzed, stored and converted inside the intelligent management unit and then sent from the M61850_S module to the station control layer network.

3. After receiving the signal from the intelligent management unit on the station control layer network, the T61850_C end of the test system parses it into "Ref+value" data and then sends it to the HMI.

4. HMI compares the received "Ref+ value" with the "Ref+ value" of the taken signal. If they are consistent, it is correct, otherwise it is an error.

5. Set the value of the extraction signal to 0 (percentile) and repeat steps 1 to 4.

In addition, due to the rapid development of local protection technology, the network structure diagram of the intelligent management unit shown in Figure 6 has also appeared. Among them, the intelligent management unit is not connected to the station control layer network, but is directly transmitted to the remote maintenance master station through the IEC 103 protocol. Although this mode is different from Figure 1, for the test technology of the intelligent management unit, except for the different upward communication protocols (Figure 1 is 61850 protocol, Figure 6 is 103 protocol), the test technology and test process of the intelligent management unit are basically the same, so the test method and test system of the present invention are also suitable for the test of the intelligent management unit of this network structure.

The HMI end, T61850_C end and T61850_S end of the test system of the present invention are completely decoupled and do not affect each other. Different test cases only need to be edited in the HMI and are not related to the T61850_C end and T61850_S end. The test system can automatically complete the functional test of the intelligent management unit.

In addition, DL/T 860 is the communication standard between the station control layer equipment and the bay layer equipment in the substation. When it is applied to the communication between the intelligent management unit and the remote master station, it needs to be appropriately expanded according to the characteristics of the proxy mode communication. The communication between the substation secondary equipment and the remote master station is realized through the intelligent management unit, and each physical IED in the substation is mapped to the virtual IED of the intelligent management unit. The data model of the virtual IED is consistent with the physical IED, and all virtual IEDs use the same IP address to realize the data access service with the remote master station client. The intelligent management unit proxy communication mode is shown in Figure 7.

The present invention obtains the test result by communicating with the intelligent management unit and receiving the feedback signal of the intelligent management unit, thereby realizing automatic completion of the functional test of the intelligent management unit and ensuring the reliability of the operation of the intelligent management unit.
