Problems solved by technology
[0003] At present, the daily workload of operation, maintenance and commissioning of smart substations is heavy, and the time is tight. There are uncertainties in the infrastructure construction time for new construction or reconstruction and expansion, and the situation of squeezing the time for secondary commissioning occurs from time to time. Therefore, relying on the digitization and networking of the secondary system of smart substations Starting from the two aspects of improving the correctness of the virtual circuit in the offline reconstruction and expansion of the busbar protection and strengthening the ability to check the early warning of the configuration change of the on-site protection equipment, it will undoubtedly promote the reconstruction and expansion projects of smart substations with less power outages and without power outages, and improve the efficiency and expansion of smart substations. security, positive

The invention discloses an on-site verification device for busbar protection in intelligent substation reconstruction and expansion, which includes a communication interface module, a decoding and channel matching module, a signal distribution module, a first signal buffer module, a second signal buffer module, a signal comparison module, a filter module, a human Computer interaction module and SCD file analysis module. The invention also discloses an on-site verification method for busbar protection in reconstruction and expansion of intelligent substations. The invention provides an on-site verification method for checking whether the change of busbar protection configuration affects the operation interval during the reconstruction and expansion process, which can timely check the configuration change and early warning during the busbar protection reconstruction and expansion process.
Description
technical field [0001] The invention relates to the technical field of intelligent substations, in particular to an on-site verification device for busbar protection in reconstruction and expansion of smart substations, and also relates to a method for on-site verification of busbar protection for reconstruction and expansion of smart substations. Background technique [0002] With the large-scale construction of smart substations, smart substations have gradually shifted to the stage of operation, maintenance and reconstruction. From a technical point of view, most of the reconstruction and expansion involve the change of the busbar protection configuration file. After the busbar protection configuration file is changed and downloaded, how to ensure that the normal operation of the live interval will not be affected, and to minimize on-site transmission or even no transmission, it is urgent to need corresponding technical tools or Technical method support. [0003] At pres...
