The system relies on issuing and receiving orders by phone, with no technical linkage between dispatch orders, operation tickets, and operation execution.
Manual ticketing or modification of typical tickets is used, resulting in low efficiency and a high error rate.
The process mainly relies on manual review, lacking real-time status-based misoperation prevention logic verification measures. This results in low review efficiency and a higher risk of errors.
Remote sequence control/remote control operations and on-site operations lack unified management, leading to risks such as skipping steps or performing unnecessary actions, which result in non-compliance with operation tickets.
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.
Through whole process
The new generation of centralized control systems, the centralized anti-misoperation main station, and the power grid resource business middle platform enables the integration of the production control area, information management area, and internet area are integrated, which enables the full digital workflow of substation disconnector operations.
Full-process anti-misoperation
Utilize technical measures such as order parsing and binding, intelligent ticket generation, real-time anti-misoperation verification, and real-time online monitoring to strengthen risk control throughout the switching process, including order reception, ticketing, review, execution, and feedback, ensuring the safety of disconnector operations.
Intelligent promotion
By leveraging AI and deep learning topology analysis technologies, combined with full equipment schematic models and real-time status, the system enables dispatch order parsing, intelligent ticket generation, and graphical ticketing, which significantly improves ticketing efficiency.
Data integration and sharing
The system integrates schematic models and logical rules for primary equipment, secondary equipment, grounding stakes, and network gates between main and substations. This unifies misoperation prevention data and enables same-source maintenance, reducing the workload for maintenance and verification.
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.
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.

Based on microcomputer anti-misoperation technology, the safety management and control solution 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 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.
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.
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.
