Currently, the mechanical interlock of primary equipment cannot achieve interlocking between devices in different bays, and electrical interlocking is insufficient to prevent misoperations such as entering the wrong bay or attaching a grounding wire to live equipment.
There is a lack of simulation rehearsal technical measures, failing to meet the standard requirement that "before disconnector operations, a verifying simulation rehearsal must be conducted, and the operation should only proceed after no errors are found."
The equipment lacks control over exclusive operation permissions. When multiple teams are performing cross-operations, there is a safety risk of simultaneous operations on the same equipment at the station control level, bay level, and equipment level.
Traditional pin tumbler and pentagon-style interlocking locks are easily duplicated, and the lock cylinder's resistance to prying and theft is low, allowing technical tools to easily unlock them.
The microcomputer anti-misoperation interlocking system consists of hardware and software. Hardware includes computers, computer keys, anti-misoperation locks, and accessories, while software includes anti-misoperation system software, graphic software, multi-tasking operation software, and communication interfaces. The system features equipment status alignment, simulated operations, anti-misoperation interlocking, and operation ticket management. It uses computer keys for on-site unlocking and data reception/transmission, and various locks for on-site equipment locking, preventing electrical equipment misoperation and ensuring safe, controllable disconnector operations.
Comprehensive anti-misoperation interlocking
It provides comprehensive anti-misoperation interlocking functions, meeting the anti-misoperation check and mandatory interlocking needs of various electrical equipment types, complex wiring configurations, and flexible operational methods.
Anti-misoperation simulation rehearsal
Before operations, the system performs anti-misoperation rule validation through simulation rehearsal, ensuring the operation complies with electrical system safety regulations and equipment operation requirements.
Unique operation right
At any time, only one person is granted operation permissions for any equipment, preventing misoperation accidents caused by overlapping operation permissions.
High-safety lock
Blade lock design supports hierarchical and zonal control, meeting high-safety requirements.
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.
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.
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.
JOYO advanced minicomputer-based anti-misoperation integrated operation system has evolved through three generations of substation microcomputer anti-misoperation technology, accumulating experience from over 40,000 substations. By introducing innovative design concepts and leading key technologies, it serves such functions as simulated operation, anti-misoperation interlocking, and operation ticket management. The system utilizes a computer key to unlock on-site equipment, receive, and transmit data, while various locks are used to interlock on-site equipment, preventing electrical misoperations and ensuring safe and controllable disconnector operations.
The substation maintenance safety management and control system enhances the locking and control functions for substation maintenance, and adds mandatory interlocking for secondary safety measures, maintenance topology verification, pre-test directed authorization, and online equipment status verification. It also integrates the maintenance workflow with existing anti-misoperation devices/systems to establish a comprehensive safety management system for the entire maintenance process, including safety measure deployment, operation control of safety measure devices, maintenance equipment drive operation, safety measure removal, and equipment status comparison, improving the production safety level of substation maintenance.
The intelligent 3D anti-misoperation system ensures safety management and control during disconnector operations, equipment maintenance, and routine inspections by utilizing 3D visualization of the work site, real-time personnel positioning, trajectory tracking, violation detection, and real-time voice alarms for risks. This system effectively prevents unsafe and non-standard operations, such as exceeding work boundaries, entering live bays by mistake, or misoperation of equipment, which provides strict control over personnel trajectories, work areas, and operational behaviors.
