Research on Do-Not-Disturb Technology for Substation Reconstruction and Expansion Based on Panoramic Model

Proposing a do-not-disturb method for substation monitoring system reconstruction and expansion based on panoramic model data. During the initial construction of the substation, the panoramic model data of the entire substation is drawn according to the long-term scale, including the line bays to be expanded. Soft pressure plate signals are added to each bay model of the entire substation to determine whether they participate in logical operations. The monitoring backend draws and transmits the database, graphic images, sequence control tickets, five prevention interlocking, reports, and forwarding tables at once based on the panoramic integrated model data, and performs panoramic interlocking logic configuration for cross bay measurement and protection equipment; The monitoring backend calculates the input or output status of the soft pressure plate based on the bay model logic to determine whether to set the current bay data to a valid state. The measurement and protection equipment calculates the input or output status of the soft pressure plate based on the cross bay and ontology bay logic to determine whether the corresponding interlocking signal of the bay is participating in the logical operation normally. Through the above methods, the operational risk of the Substation expansion work is reduced and the expansion workload is reduced.
