In this embodiment, communication rules between the in-place module device and the two measurement and control devices (measurement and control network a and measurement and control network B) in the HSR ring network are formulated, and the communication rules include GOOSE and SV information communication rules sent by the in-place module device and GOOSE information communication rules received by the in-place module device. These rules are expressed as the following control flow.
The configuration method of the on-site module device suitable for the third-generation intelligent substation is shown in a corresponding flow chart in fig. 2, and comprises the following steps:
(1) Acquiring setting data n of the on-site module device; acquiring initial value information of a sending data set in a configuration file; and acquiring initial value information of the received data set in the configuration file.
The configuration file is a maximum configuration file preset by the localized module device, and of course, the configuration file may also be a certain subfile of the maximum configuration file under the condition that it is ensured that all information to be acquired can be acquired. Specifically, the sending of the initial value information of the data set in the configuration file includes: GOOSE sends the device name IEDNAME and logical device LD of the data set, GOOSE sends the MAC address and APPID address of the data set, SV sends the device name IEDNAME and logical device LD of the data set, and SV sends the MAC address and APPID address of the data set. The initial value information of the received data set in the configuration file comprises: GOOSE receives logical device LD of data set, GOOSE receives MAC address and APPID address of data set.

The setting data n is display data of an LED nixie tube of the in-place module device, the setting data n of each in-place module device is not allowed to be repeated, and the setting data n is obtained in a setting mode on site. When the display data of the LED nixie tube of the on-site module device is set to be n, only a data set with n suffix of the LD in the information issued by the measurement and control device is received, and the information with the MAC address of the data set of 01-0C-CD-01-00- (80 + n) and the APPID of 0x00 (80 + n) is received. As shown in FIG. 2, to avoid program error, a judgment process of setting data n can be added, when n is greater than 0, the following steps are continued, and when n is less than 0, an error is initialized and the operation lamp is turned off.
(2) When the on-site module device is started, modifying the device name IEDNAME and the logic device LD in the sending data set according to the setting data n, modifying the MAC address and the APPID address of the GOOSE sending data set, and modifying the MAC address and the APPID address of the SV sending data set; when the on-site module device is started, the logic device LD in the received data set is modified according to the setting data n, and the MAC address and the APPID address of the received data set are modified.
As shown in fig. 2, the modification process of the sending data set and the receiving data set specifically includes:
when the in-place module device is started, the configuration program (process layer interface program) processes the GOOSE sending data set: adding suffix setting data n to the initial value of the device name IEDNAME and the logic device LD of the GOOSE sending data set according to the initial value information and the setting data n of the GOOSE sending data set in the acquired configuration file; modifying the last bit of the initial value of the APPID address of the GOOSE sending data set into setting data n; and modifying the last bit of the MAC address of the GOOSE sending data set into setting data n. And after the GOOSE sending data set is processed, sending the processed data to the ring network.
According to the modification mode, in the implementation, the MAC initial address 01-0C-CD-01-00-01 of the GOOSE transmit data set is modified to 01-0C-CD-01-00-0n, and the APPID initial address 0x0001 of the GOOSE transmit data set is modified to 0x000n.
When the in-place module device is started, a configuration program (a process layer interface program) processes SV sending data sets: adding suffix setting data n to the initial value of the device name IEDNAME and the logic device LD in the SV sending data set according to the initial value information and the setting data n of the SV sending data set in the acquired configuration file; modifying the last bit of the initial value of the APPID address of the SV sending data set into setting data n; the last bit of the MAC address of the data set sent at SV is modified to a tuning data n. And after the SV sending data set is processed, sending the processed data to the ring network.
According to the modification mode, in the embodiment, the MAC initial address 01-0C-CD-04-00-01 of the SV sending data set is modified into 01-0C-CD-04-00-0n, and the APPID initial address 0x4001 of the SV sending data set is modified into 0x400n.
And judging whether the measurement and control network A issues information or the measurement and control network B issues information according to the suffix of the device name IEDNAME of the GOOSE data set received by the on-site module device. For example, in this embodiment, when the device name IEDNAME suffix of the GOOSE dataset of the on-site module device receiving the measurement and control device is 01, the information is issued for the measurement and control a network; when the IEDNAME suffix of the device name of the GOOSE data set received by the on-site module device is 02, the information is issued for the measurement and control B network.
When the in-place module device is started, the configuration program (process layer interface program) processes the GOOSE received data set: adding the setting data n to the initial value of the LD in the GOOSESUB received data set according to the obtained initial value information of the GOOSESUB received data set and the setting data n; adding setting data n to an initial value of an APPID address of a GOOSESUB receiving data set; and adding setting data n to the last byte of the MAC address of the received data set by GOOSESUB. After the received data set is processed, the received data set is matched with the GOOSE data received and monitored by the optical fiber port, namely in the receiving process, whether the data format of the data received from the optical fiber port is matched with that of the received data set is judged, if the data format is matched, the data is received, and if the data format is not matched, an error is reported.
As shown in fig. 2, when information is issued for the measurement and control a network, the MAC initial address 01-0C-CD-01-00-80 of the GOOSE received data set for receiving the measurement and control a network is modified to 01-0C-CD-01-00- (80 + n), and the APPID initial address 0x0080 of the GOOSE received data set for receiving the measurement and control a network is modified to 0x00 (80 + n). When information is issued to the measurement and control B network, the MAC initial address 01-0C-CD-01-01-80 of the GOOSE receiving data set of the measurement and control B network is modified to be 01-0C-CD-01-01- (80 + n), and the APPID initial address 0x0180 of the GOOSE receiving data set of the measurement and control B network is modified to be 0x01 (80 + n).
In the above modification of the device name IEDNAME and the logic device LD and the APPID address, MAC address, the last bit may be directly modified to the tuning data n or the tuning data n may be added to the last byte. For example, if the last two bits are 01, then it is directly changed to 0n, in which case n does not exceed 15; for 00 or 80, adding the tuning data n on the last byte can exceed 15. Of course, the modification mode is flexible, and a person skilled in the art can freely make the modification mode according to the tuning data n.
It should be noted that, the sequence of the setting data n of the localized module device, the initial value information of the sending data set in the configuration file, and the initial value information of the receiving data set in the configuration file, which are obtained in step (1), and the sequence of the modification of the sending data set and the receiving data set in step (2) do not require strict time sequence, and the sequence can be adjusted as required.
