Description
Technical Field
The invention belongs to the technical field of power system automation, and particularly relates to a GOOSE data sending method and device, and a configuration method and device.
Background
At present, the logic locking function of a measurement and control device in the field of power system automation is a commonly applied basic function, and the logic locking condition usually needs to judge information of other intervals besides the information of the interval. The other interval information is obtained by interacting GOOSE information between the measurement and control devices, as shown in fig. 1.
The measurement and control device GOOSE generally adopts a fixed preset mode to send a data set, namely: and configuring a GOOSE sending data set in advance during program development, establishing an association relation between the data set and data of the device, and writing data into the sending buffer area when the corresponding data changes.
There are two ways to fix the preset mode.
One is to pre-configure GOOSE transmit data sets as required. Because the mode is according to the engineering requirement, redundant information does not exist, and the safety and the stability of the system are higher. However, because the logic locking condition is related to the primary system main connection form, the regional requirement, the information acquisition mode, the device configuration mode, and other factors, the difference of these factors inevitably causes the change of the logic locking condition, and further causes the change of GOOSE interactive data between devices, and the preset GOOSE transmission data cannot satisfy all different engineering conditions, and the program is often modified to increase the GOOSE transmission data in the engineering implementation. The method has the advantages of long engineering debugging period, low working efficiency and difficult guarantee of reliability.
Another is to adopt a general method to preset GOOSE sending data set in order to meet most engineering requirements. The mode considers the situation according to the maximization and fixes the whole network transmission when the GOOSE transmission information is preset, and can adapt to various engineering application conditions. However, GOOSE sends more data, and only a part of GOOSE data or even all GOOSE data is needed in practical application. Therefore, a large amount of redundant GOOSE sending information exists in the monitoring system network, the network bandwidth is occupied, and adverse effects are brought to the safe and stable operation of the system.
In summary, there is a contradiction in the fixed preset mode, otherwise different engineering requirements cannot be met, otherwise the GOOSE sends data with more redundant information, which results in unstable system.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and examples, but the embodiments of the present invention are not limited thereto.
According to the GOOSE data sending method and the configuration method, a traditional mode of pre-solidifying the GOOSE sending data set is not used, a dynamically defined configuration method is adopted, in a specific practical project, required data are selected from all the sent MMS data sets according to the configuration condition of the logic locking condition, and the data are deployed into the GOOSE sending data set of the station control layer according to types, so that the GOOSE sending data are dynamically deployed according to the project requirements. The flow chart of the method is shown in fig. 4, and specifically includes:
firstly, several GOOSE sending data sets preset as empty by the measurement and control device according to different data types, and no member is added in the data sets, as shown in fig. 2.
Then, the SCD file is analyzed to obtain the MMS data set which is just sent to the monitoring system and the engineering logic locking condition.

After the completion of these operations, CID configuration files are generated, thereby realizing the configuration of GOOSE data transmission.
On the basis of completing the above configuration, the following method is adopted to transmit GOOSE data.
And after the GOOSE sends the data set to realize engineering configuration, downloading the generated CID configuration file into the device. And the CID configuration file represents the modification of the GOOSE data set, and the gateway sends GOOSE information to the network according to the configuration file.
After the CID configuration file is downloaded to the device, when the device runs, the program analyzes the GOOSE sending data set information in the CID file, and creates and memorizes a corresponding association relation table between the member information in the GOOSE sending data set and the MMS data.
