With the construction and promotion of the "new generation of centralized control stations" and "intelligent one-click sequential control" by the State Grid Company, sequential control operations have significantly improved operational efficiency. However, they have also introduced new challenges. Since operators are not on-site, they cannot determine whether the secondary protection of the operation target is fully engaged. Substations currently lack mature technical measures for preventing misoperations during secondary operations (such as the engagement and disengagement of soft and hard pressure plates). In most cases, these operations still rely on "human prevention.” The existing anti-misoperation systems are no longer adequate to meet the new requirements for preventing misoperations in sequential control operations. Building on the existing anti-misoperation functions at the station end, this system extends secondary anti-misoperation capabilities. When operating primary equipment, it adds secondary equipment operation status judgment to the existing anti-misoperation criteria. When operating secondary equipment, it judges the operation status of primary equipment and implements anti-misoperation interlocking between secondary equipment. This achieves comprehensive coverage of anti-misoperation interlocking functions, fully meeting the requirements of “full sequential control”, “full anti-misoperation”, and “full process” operations.
