Title:
BUS/LINE GROUNDING LINE SELECTION ALTERNATE REMOVAL METHOD BASED ON SCADA DATA
Document Type and Number:
WIPO Patent Application WO/2023/060705
Kind Code:
A1
Abstract:
Disclosed in the present invention is a bus/line grounding line selection alternate removal method based on SCADA data. The method comprises: S1, SCADA collecting various pieces of data in real time; S2, the SCADA periodically calculating whether there is a bus/line grounded; S3, if there is a bus/line grounded, performing fault location and pushing a grounding alarm signal; S4, calculating influence factors that cause a grounding possibility, so as to form a grounding switch-out sequence table; S5, according to the grounding switching-out sequence table, sequentially performing remote control switching-off on circuit breakers which correspond to the influence factors, and determining whether a grounding fault is eliminated until the grounding fault is eliminated; and S6, if the grounding fault has been eliminated, repeating steps S2 to S5. The present invention is different from a small-current grounding line selection apparatus of a substation, and real-time monitoring of the bus/line grounding situation of substations is realized from a dispatching side by using telecontrol remote transmission data received by a dispatching end and real-time collected data of various substations in an SCADA system, thereby providing decision-making assistance for production maintenance and electric power dispatching.
