The computer key does not communicate with the anti-misoperation host in real-time, lacking real-time anti-misoperation verification; the status of grounding wires is not collected in real-time, posing a risk of incomplete removal.
The state of some air switches and hard pressboards is manually inspected, which is inefficient and unreliable; secondary equipment is not linked to primary equipment for anti-misoperation, lacking joint anti-misoperation measures for primary and secondary equipment, posing risks of missed or incorrect operations.
The absence of mandatory interlocking for secondary safety measures poses risks of accidental activation or contact; the unlocking for maintenance transmission (testing) is not linked to task-specific technical requirements, creating potential for misoperation.
Permissions, data, and functions across anti-misoperation systems, lock control systems, and other systems are not effectively integrated, lacking data sharing and business collaboration.
With "safety and efficiency" as the goal, and "business collaboration" and "data integration" as the core, based on the requirements of one-click sequence control, intelligent substations, and centralized control station construction, the system adheres to the new-generation architecture of substation secondary products that are autonomously controllable and compliant with information security standards. It relies on new technologies such as "big data, cloud computing, IoT, AI, and intelligence" and introduces innovative applications such as intelligent sensing, intelligent ticketing, intelligent verification, and intelligent maintenance. This expands anti-misoperation control from primary equipment operations to secondary equipment operations, maintenance tasks, and O&M activities, achieving comprehensive anti-misoperation safety management and control.
Full anti-misoperation mechanism for operations
To address the deficiencies in traditional anti-misoperation practices in substations, the anti-misoperation concept must be extended from primary equipment misoperation (local operations, remote operations, and sequence control operations) prevention to include secondary equipment anti-misoperation, equipment maintenance (both primary and secondary equipment maintenance), and full anti-misoperation control for daily O&M activities (equipment inspections and routine maintenance).
Full service coverage
Based on various practical business scenarios such as substation disconnector operations, maintenance tasks, and O&M activities, the system expands comprehensive anti-misoperation applications across multiple scenarios. It achieves vertical integration between main and sub-stations for multi-business coordination, provides horizontal coverage across all security zones, and supports a modular design for full business coverage.
Entire process control
The system covers various operational tasks and work scenarios, involving primary, secondary, and auxiliary control equipment. It spans across inspection, switching, and maintenance processes, achieving full control from the source of the operation to the closed-loop management of the entire process.
Intelligent application
Based on network topology for anti-misoperation verification, the system uses expert databases and natural language processing technologies to implement intelligent ticketing, intelligent verification, and intelligent maintenance isolation. Unified anti-misoperation locks, auxiliary control locks, and isolation locks are used to achieve one-key control of O&M tasks.
With digital two-ticket processing as the business hub, the system integrates the new power system's three zones and four layers, fully covering scenarios such as disconnector operations, maintenance, and O&M tasks, enabling online two-ticket processing, mobile operations, transparent information, and intelligent support. This promotes the deep integration of digital technology with equipment management throughout all processes and stages, improving team efficiency and ensuring the safety of on-site operations, thus supporting the digital transformation of power companies.

Based on microcomputer anti-misoperation technology, the safety management and control system for substation operation and inspection targets every aspect of integrated O&M workflows, including switching, maintenance, and repair operations. Through process refinement and system applications, combined with existing innovative technologies, it establishes a platformized, networked, and intelligent substation O&M safety management and control system. This platform fully covers safety control for O&M and repair across multiple disciplines, effectively improving work efficiency, reducing operational costs, and enhancing power safety production levels.
To meet the anti-misoperation requirements of one-key sequence control in substations, relying on nearly 30 years of experience in anti-misoperation product development, the system achieves dual verification of sequence control anti-misoperation while introducing new features such as directional authorization unlocking, grounding wire status collection, and graded and zoned lock management. These improvements enhance the safety and efficiency of on-site operations.

In line with the business needs for intelligent O&M under the power grid company's "centralized control station+unmanned substation+equipment ownership" model, a safe, stable, reliable, and user-friendly anti-misoperation system is developed for main and substations by leveraging key technologies such as "PMS interconnection, remote control (sequence control) constraints, operation permission management, and information monitoring" to support the new substation O&M management model, enhancing the safety management and control level of the regional power grid.
Based on the new generation of centralized control systems and PMS, build anti-misoperation applications for centralized control stations, intelligent ticketing micro-applications, and mobile applications, linking the production control area, management information area, and internet area. This will establish a digital workflow for disconnector operations, a mobile execution model, realizing intelligent ticketing, real-time anti-misoperation throughout the process, unlocking and closing the loop in management, and unified management of operational information, which enhances the quality and efficiency of disconnector operations at centralized control stations and ensures the safety of on-site operations.
Focusing on on-site operation and inspection tasks, and adhering to the "three zones, four layers" design architecture, an intelligent ticketing and mobile operation application is built with the enterprise middle platform as the backbone. This solution enables online management of the two-ticket process, mobile operations, transparent information, and intelligent support. It promotes deep integration of digital technology with the entire process and every aspect of equipment management, enhancing team work efficiency and quality, ensuring on-site operational safety, and providing a foundation for the construction of digital teams.
