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.
Through whole process
With two-ticket processing as the main construction line, the system integrates the new power system's three zones and four layers, connecting systems such as PMS, dispatching, centralized control, and anti-misoperation, achieving end-to-end two-ticket operation, simplifying business processes, improving operational modes, and enhancing operational safety.
Mobile operations
Focusing on the needs of front-line personnel, the system integrates business processes, mobile applications, and terminal interconnectivity to achieve online, mobile, and transparent production operations, enhancing on-site operational capabilities and safety management and control.
Intelligent business
The system enhances the innovation of two-ticket business applications by introducing technologies such as semantic recognition, machine learning, expert knowledge databases, and topology analysis to achieve intelligent parsing, intelligent ticketing, and intelligent verification, optimizing the user experience and improving work quality and efficiency.
Unified data maintenance
Supported by the enterprise middle platform, the system promotes unified data models for both the I-area anti-misoperation system and the IV-area two-ticket application, reducing data maintenance workload and meeting the need for data integration and sharing.
To address the business needs of intelligent O&M under the "centralized control station+unattended substation+equipment owner system" model of power grid companies, the system utilizes key technologies such as "PMS interconnection, remote control (sequence control) constraints, operation rights management, and information monitoring" to address issues such as low efficiency of ticket preparation at the centralized control main station, lack of safety constraints in remote/sequence control operations, incomplete control information, and insufficient business coordination between systems. This supports the new substation O&M management model and enhances the safety management and control level of regional power grids.
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.
