Industry Background

Solution Overview

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.

方案优势

Comprehensive status awareness

Comprehensive status awareness

By using magnetic sensing technology, DC electric field sensing technology, and RFID IoT technology, the system not only achieves "dual confirmation" for primary equipment such as circuit breakers and isolators (grounding switches) but also collects the status of secondary equipment such as control panels, switches, and handles, providing full state awareness for substations.

Full remote control of equipment

Full remote control of equipment

Based on the one-click sequence control of primary equipment, the system applies micro-motor control technology and intelligent sensing technology to secondary equipment such as bus tie power supplies, reclosing control panels, and voltage-parallel handles, achieving full remote control of secondary equipment, such as switches and handles, as part of the one-click sequence control process.

Comprehensive anti-misoperation verification

Comprehensive anti-misoperation verification

Expanding from primary to secondary anti-misoperation verification, the system establishes a comprehensive anti-misoperation logic, covering primary-to-primary, primary-to-secondary, secondary-to-secondary, and secondary-to-primary verification. During the one-click sequence control simulation and step-by-step execution, the system performs real-time anti-misoperation logic verification for the coordination of primary and secondary equipment, significantly enhancing the safety of one-click sequence control operations.

Comprehensive operation coverage

Comprehensive operation coverage

Currently, the sequence control operations of State Grid and China Southern Power Grid primarily achieve switching between operational, hot standby, and cold standby states. This system, through comprehensive monitoring of secondary equipment status and remote control with dual confirmation of grounding disconnectors, can achieve one-click sequence control switching among operational, hot standby, cold standby, and maintenance states, further enhancing the O&M efficiency.

Disconnector Double-Confirmation Solution for Substations

Disconnector Double-Confirmation Solution for Substations

The magnetic induction double-confirmation device mainly consists of a magnetic induction sensor and a receiving device. The magnetic induction sensor uses a non-contact induction principle to detect the status of the disconnector and transmit the status information to the receiving device. The receiving device is installed in the control cabinet, terminal box, or independent cabinet, achieving logical calculation and status output of the disconnector status signal. The magnetic induction double-confirmation device features safe and reliable non-contact detection, easy installation, and suitability for various equipment types and operating environments. It accurately identifies the open/close status of disconnectors, providing a more secure and reliable technical guarantee for one-click sequence control.
