Conventional anti-misoperation systems can achieve remote and local operation misoperation prevention checks, but lack double verification functions for sequence control operations from different sources, making it difficult to ensure the safety and reliability of sequence control operations.
The anti-misoperation system lacks the status of exit clamps, bus coupler clamps, and other clamps, so secondary equipment cannot participate in anti-misoperation logic checks. This poses a risk of primary equipment operating without protection, with low inspection efficiency and a high risk of human error.
During the transition from cold standby to operation in sequence control, there is a lack of status collection for grounding wires that have interlocking logic with the isolating switch. This prevents real-time misoperation logic judgment and poses a risk of energizing the system while the grounding wire is still connected.
The current unlock key can unlock all anti-misoperation locks on-site. Once operators obtain the unlock key and go to the wrong bay, it easily leads to equipment misoperation and accidents.
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.

The intelligent energy O&M control system is primarily designed for supply-side energy users, including photovoltaic stations, wind turbines, energy storage stations, charging stations, integrated energy stations, and multi-energy integration stations. It facilitates intelligent O&M and monitoring across these scenarios, enabling intelligent energy O&M on the regional energy production and supply side.
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 one-click sequence control system for substations 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.
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.
