[0002] With the development of high-voltage direct current transmission technology, many direct current transmission projects have been built. Since the station status of the converter station needs to be sent to multiple dispatchers, most of the telecontrol program parameter configurations are determined at the beginning of the station construction. If the dispatcher needs to send certain status later, it is necessary to send people to the station to modify or add telecontrol program configuration parameters to meet the new requirements.

[0003] The dispatcher proposes certain status parameters of the specific converter station to be sent up, and the control and protection manufacturer sends employees to add and modify the parameters. This method has the following defects: (1) Manual addition and modification of parameters may result in errors; (2) The parameters cannot be modified in time, which is inefficient.

[0030] Provides a method for automatic configuration of remote control system parameters of DC transmission projects. Figure 1 , including the following steps:

[0031] The format for parameter configuration agreed upon between the S100 master station and the slave station.

[0032] In the telecontrol system, the master station and the substation agree to configure parameters in XML format.

[0033] The master station is a dispatching center, and the substations are various manufacturers.

[0034] The S200 slave station configures basic data based on a configuration file in a specified format.

[0035] The substation loads the configuration file, parses the initial table in XML format, and configures the basic data. The basic data includes remote signaling, remote adjustment, and remote control. The substation configures the database based on the basic data points.

[0036] S300 The master station calls the basic data configured by the slave station. The master station issues the calling instruction through the private network, and the calling instruction belongs to the specified instruction of the 104 protocol. After receiving the instruction from the master station, the slave station packages the basic data point file and sends it to the master station in the specified format.

[0037] S400 The master station processes the basic data to form an updated configuration file and sends it to the slave station.

[0038] The dispatching personnel modify the XML file of the basic data at the main station, and after the modification is completed, a secondary table is formed and sent to the substation as an updated configuration file.

[0039] The S500 slave station performs verification. After passing the verification, it parses and updates the configuration file and updates the basic configuration data. Verification is performed through the verification code in the protocol. If the verification fails, an error message is fed back to the master station.

The master station calls the substation to configure the basic data; the master station processes the basic data to form an updated configuration file and sends it to the substation; the substation performs verification, and after passing the verification, it disconnects the communication with the master station, parses the updated configuration file and updates the configuration basic data, and resumes communication with the master station after the configuration is completed.

[0042] Furthermore, the master station is a dispatching center, and the substation is a manufacturer.

[0043] Furthermore, the configuration file format is XML format.

[0044] Furthermore, after passing the verification, the method further includes: disconnecting the communication with the master station, and resuming the communication with the master station after the configuration is completed.

[0045] Furthermore, the verification includes verification through a verification code in the protocol, and if the verification fails, error information is fed back to the main station.
