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.
Sequence control anti-misoperation
An intelligent anti-misoperation host is set up to provide independent anti-misoperation verification for sequence control operations performed by the monitoring host (sequence control host), meeting the "dual verification" requirements for one-key sequence control operations, ensuring the safety and reliability of the process.
Local anti-misoperation
To meet the anti-misoperation requirements of local operations, local anti-misoperation units, anti-misoperation computer keys, and anti-misoperation locks are set up. Used for anti-misoperation control during the transition from sequence control to manual mode, as well as for conventional local disconnector operations.
Secondary anti-misoperation
Performs anti-misoperation verification for both primary and secondary equipment operations, while automatically verifying the operation modes against standard procedures.
Directional unlocking
Based on the principles of graded usage and directional authorization, the system uses layered visual selection to unlock devices. QR codes are used to apply for and authorize unlocking information across regions, strictly limiting the scope of unlocking operations. This effectively prevents unauthorized expansion of the unlocking range, thus enhancing the safety of on-site unlocking operations.
Traditional disconnector operations face challenges such as complex procedures, low operational efficiency, and high risks of misoperation, making them unable to meet the demands of lean substation management and the digitalization of power grids. The JOYO-A1 substation one-click sequence control system is built on integrated substation monitoring and intelligent anti-misoperation technologies, combining magnetic sensing, micro-motor control, and secondary anti-misoperation technologies. It creates a new generation of one-click sequence control system with "comprehensive state awareness, full remote control of equipment, comprehensive anti-misoperation verification, and full coverage of operations," providing intelligent, efficient, and safe substation operation solutions for customers in the power grid, power plants, and petrochemical industries.

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 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.
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.
Voltage detection interlocking is a simple and practical intelligent management and control solution proposed according to the requirements of distribution network operation management and control and the characteristics of distribution network equipment. By using high-voltage voltage detection devices with anti-misoperation interfaces in conjunction with grounding switch equipment, the system enforces mandatory voltage detection before operating grounding switch equipment, addressing misoperation issues such as "live grounding disconnector closing," "power-on with grounding," and "entering live dangerous areas" during distribution network equipment operations.
The distribution network operation safety management and control system focuses on risk prevention and control in operational safety, targeting the management and supervision of distribution network O&M and disconnector operations. The system adopts a cloud-based architecture and deployment, relying on the "cloud platform" to achieve real-time online dynamic perception, operation control, and digital mobile operations for the entire process of distribution network on-site work, addressing safety issues during field operations and improving the quality and efficiency of maintenance personnel management.
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 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.
