Description

Technical Field

[0001] The invention belongs to the technical field of power system automation, and in particular relates to a substation monitoring information automatic acceptance system and method. Background Art

[0002] At present, most substations are managed in unattended mode, and a large amount of substation monitoring information needs to be connected to the dispatching master station. Since the monitoring information reflects the operating status of the substation equipment, accurate monitoring information is the guarantee for the safe operation of the power grid. Therefore, during the substation acceptance process, monitoring information acceptance is an important part of the substation acceptance.

[0003] Traditional monitoring information acceptance is done manually one by one. First, the monitoring information acceptance is completed within the station. The primary and secondary equipment debugging personnel then trigger the information upload. Then the monitoring acceptance personnel on the master station side and the on-site debugging personnel conduct information verification and acceptance. In this mode, all work requires full manual participation, especially when verifying with multiple master stations. The same work needs to be repeated several times, and the acceptance efficiency is low.

[0004] Therefore, in order to solve the above problems, it is necessary to develop an automatic acceptance system and method for substation monitoring information. Summary of the invention

[0008] Furthermore, when the master station data verification module verifies the three tables of telesignaling, telemetering and remote control at the master station, the telesignaling information table mainly verifies the point number, information description, voltage level, alarm type and whether it is an optical sign, while the telemetering information table and the remote control information table only verify the point number and information description.
