Detailed ways

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Embodiments of the configuration method of the localized modular device suitable for the third-generation smart substation:

When the localized modular device leaves the factory, make the maximum configuration file of each type of localized modular device, complete the connection of all virtual terminals of this type of localized modular device to receive the measurement and control device, and connect the corresponding type of localized modular device The maximized configuration file is downloaded into the localized modular unit.

In this embodiment, the communication rules between the localized modular device and the two sets of measurement and control devices (measurement and control A network and measurement and control network B) in the HSR ring network are formulated, and the communication rules include that the localized modular device sends GOOSE and SV information Communication rules, and communication rules for localized module devices to receive GOOSE information. These rules manifest as the following control flow.

The configuration method of the localized modular device suitable for the third-generation smart substation, the corresponding flowchart is shown in Figure 2, including the following steps:

(1) Obtain the setting data n of the localization module device; obtain the initial value information of the sending data set in the configuration file; obtain the initial value information of the receiving data set in the configuration file.

The configuration file here is the maximized configuration file preset by the localized modular device. Of course, the configuration file may also be a certain sub-file of the maximum configuration file under the condition that all the required information can be obtained. Specifically, the initial value information of the data set sent in the configuration file includes: the device name IEDNAME and the logical device LD of the data set sent by GOOSE, the MAC address and APPID address of the data set sent by GOOSE, the device name IEDNAME and the logical device of the data set sent by SV LD, and the MAC address and APPID address of the data set sent by the SV. The initial value information of the data set received in the configuration file includes: the logical device LD of the data set received by GOOSE, the MAC address and APPID address of the data set received by GOOSE.

Wherein, in this embodiment, the initial MAC address of the data set sent by GOOSE is 01-0C-CD-01-00-01, the initial address of APPID of the data set sent by GOOSE is 0x0001; the initial address of the MAC sent by the SV data set is 01 -0C-CD-04-00-01, the initial APPID address of the data set sent by the SV is 0x4001.

The setting data n is the data displayed by the LED digital tube of the localized modular device. The setting data n of each localized modular device is not allowed to be repeated. When the LED digital tube display data of the localized module device is set to n, only the data set with the LD suffix of n in the information released by the measurement and control device is received, and the MAC address of the received data set is 01-0C-CD-01-00- (80+n), APPID is 0x00(80+n) information. As shown in Figure 2, in order to avoid program errors, the judgment process of the setting data n can also be added. When n>0, continue the following steps;

(2) When the localized module device is powered on, according to the setting data n, modify the device name IEDNAME and logical device LD in the sending data set, and modify the MAC address and APPID address of the GOOSE sending data set, and send the SV The MAC address and APPID address of the data set are also modified; when the localized module device is powered on, the logical device LD in the receiving data set is modified according to the set data n, and the MAC address and APPID address of the receiving data set are modified. .

As shown in Figure 2, the modification process of the sending data set and the receiving data set specifically includes:

When the localized module device is powered on, the configuration program (process layer interface program) processes the GOOSE sending data set: according to the initial value information of the GOOSE sending data set and the setting data n in the obtained configuration file, the GOOSE sending data set is Add the suffix setting data n to the initial value of the device name IEDNAME and the logical device LD; modify the last digit of the initial value of the APPID address of the GOOSE sending data set to the setting data n; modify the last digit of the MAC address of the GOOSE sending data set is the setting data n. After the data set sent by GOOSE is processed, the processed data is sent to the ring network.

According to the above modification method, in this implementation, the MAC initial address 01-0C-CD-01-00-01 of the GOOSE sending data set is modified to 01-0C-CD-01-00-0n, and the GOOSE sending data set The initial address of APPID 0x0001 is modified to 0x000n.

When the localized module device is powered on, the configuration program (process layer interface program) processes the SV sending data set: according to the initial value information of the SV sending data set and the setting data n in the obtained configuration file, the SV sending data set is Add the suffix setting data n to the initial value of the device name IEDNAME and the logical device LD; modify the last digit of the initial value of the APPID address of the SV sending data set to the setting data n; modify the last digit of the MAC address of the SV sending data set is the setting data n. After the SV sending data set is processed, the processed data is sent to the ring network.

According to the above modification method, in this embodiment, the initial MAC address 01-0C-CD-04-00-01 of the SV sending data set is modified to 01-0C-CD-04-00-0n, and the SV sending data set The APPID initial address 0x4001 is modified to 0x400n.

According to the suffix of the device name IEDNAME of the GOOSE data set of the measurement and control device received by the localized module device, it is judged whether the measurement and control network A publishes the information or the measurement and control network B publishes the information. For example, in this implementation, when the localization module device receives the device name IEDNAME of the measurement and control device GOOSE data set with a suffix of 01, it publishes information for the measurement and control network A; when the localization module device receives the device name of the measurement and control device GOOSE data set When the suffix of IEDNAME is 02, information is released for the measurement and control network B.

When the localized module device is powered on, the configuration program (process layer interface program) processes the GOOSE receiving data set: according to the obtained initial value information and setting data n of the GOOSESUB receiving data set, the GOOSESUB receiving data set is set to the logic device LD in the GOOSESUB receiving data set. Add the setting data n to the initial value; add the setting data n to the initial value of the APPID address of the GOOSESUB receiving data set; add the setting data n to the last byte of the MAC address of the GOOSESUB receiving data set. After the received data set is processed, it is matched with the GOOSE data received by the optical fiber port. That is, during the receiving process, it is judged whether the data received from the optical fiber port matches the data format of the received data set. .

As shown in Figure 2, when publishing information for the measurement and control network A, modify the MAC initial address 01-0C-CD-01-00-80 of the GOOSE receiving data set of the measurement and control network A to 01-0C-CD-01- 00-(80+n), modify the initial APPID address 0x0080 of the GOOSE receiving data set of the receiving measurement and control network A to 0x00(80+n). When publishing information for the measurement and control network B, modify the initial MAC address 01-0C-CD-01-01-80 of the GOOSE receiving data set receiving the measurement and control network B to 01-0C-CD-01-01-(80+n ), modify the APPID initial address 0x0180 of the GOOSE receiving data set of the receiving measurement and control network B to 0x01(80+n).

In the above modification of the device name IEDNAME, the logical device LD, the APPID address, and the MAC address, the last digit can be directly modified to the setting data n or the setting data n can be added to the last byte. For example, if the last two digits are 01, it will directly become 0n. In this case, n does not exceed 15; for 00 or 80, add setting data n to the last byte, and n can exceed 15. Of course, the modification mode is flexible, and those skilled in the art can freely formulate the modification mode according to the setting data n.

It should be noted that, in step (1), the setting data n of the localization module device, the initial value information of the sent data set in the configuration file, and the sequence of the initial value information of the received data set in the configuration file are obtained, and step (2) ) in the order of modification of the sending data set and the receiving data set, does not require strict timing, and can be adjusted according to needs.

Through the above steps (1) and (2), the entire contents of the communication data conversion of the localized modular devices are completed, and the interaction of remote control and telemetry information between each localized modular device and the measurement and control device is realized. After the localized modular device is transported to the substation site, it is only necessary to set the setting data n of the localized modular device. After the adjustment is completed, the localized modular device is powered off and restarted. The configuration method of the localized module device of the generation of intelligent substation can realize the data exchange between the localized module device and the measurement and control device through the HSR ring network, and meets the requirements of the IEC61850 specification, without the need for on-site download of configuration files and debugging, reducing the need for The workload of on-site commissioning personnel and operation and maintenance personnel has improved the efficiency of substation construction.
