Abstract

The invention relates to a smart substation steady state data closed-loop testing method and a testing system thereof. A smart substation comprises a process layer, a spacing layer and a station control layer. The method includes establishing a virtual local area network (VLAN); acquiring SV sampling data and GOOSE state data of the process network through the corresponded VLAN; acquiring spacing layer network MMS measurement data through the corresponded VLAN; acquiring the station control layer remote gateway computer 104 transmission data through the corresponded VLAN; performing layer-crossed comparison and analysis on all the data. By the aid of the technical scheme, the verification problem that the smart substation internal steady state data cannot be tested in a closed-loop manner effectively is solved, and reliable and precision measurement data can be provided to a master station.

Description

Technical field: [0001] The invention relates to the field of electric power automation, and more specifically relates to a closed-loop test method for steady-state data of an intelligent substation and a test system thereof. Background technique: [0002] The substation is the source of grid data, ensuring the accuracy and reliability of the source data of the substation is the basis for ensuring grid operation monitoring and various intelligent evaluation and analysis. In traditional substations, the measurement data is directly transmitted from the measurement and control device to the telecontrol device, and then sent to the dispatching master station. Since the entire environment is in an open mode, the measurement and status information currently running in the substation lacks closed-loop testing and cannot be effectively implemented. To ensure the validity of data from collection to transmission, the status evaluation of the validity of the data is only carried out a...
