Centralized control stations only have single-source topology verification, lacking verification measures from different sources and dimensions, which fails to meet the safety requirements for main station sequence control/remote control operations.
Centralized control stations lack status information on anti-misoperation equipment such as grounding wires and network gates at the station, and cannot monitor the status of tools and equipment and unlock keys.
The business systems of dispatching, PMS, centralized control, and anti-misoperation lack business collaboration, making it difficult for operational data to flow online.
The anti-misoperation systems at the stations are isolated from each other, and the data cannot be effectively utilized, failing to meet the lean management needs under the centralized control O&M model.
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.
Intelligent dispatch order constraints
Using semantic recognition and intelligent ticketing technologies, the system intelligently parses dispatch orders and establishes technical connections with disconnector operations. It adopts a dual-lock mechanism of "dispatch order verification+anti-misoperation verification" to prevent unauthorized or non-compliant operations, further enhancing the safety management and control of disconnector operations.
Multi-dimensional anti-misoperation verification
For switching, maintenance, and operational tasks in regional power grids, use double verification of remote/sequence control, network topology, logical formulas, inter-station interlocking, multi-task operation permissions, and other multi-dimensional anti-misoperation checks to ensure the safety and controllability of regional power grid operations.
Online two-ticket business
Integrating PMS, dispatch, centralized control, and anti-misoperation systems allows for synchronized ticketing and simulation verification, as well as the extraction of work ticket information. This enables a fully online, closed-loop management process for the two-ticket system in substation operation and inspection.
Centralized anti-misoperation management
The centralized control main station manages all anti-misoperation data from station terminals, achieving unified management of anti-misoperation data, centralized monitoring of communication status, intelligent alarm generation, centralized monitoring of anti-misoperation information, statistical analysis of anti-misoperation assets, and auxiliary decision-making for production information, thus improving the level of anti-misoperation management under the centralized control O&M model.
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.
