Intelligent Lock Management Enhances Power Grid Security
AT500-E Intelligent Lock Management System for 500kV Yong'an Station, Pingguo Station, Chongzuo Station, and Yulin Series Compensation Station of China Southern Power Grid Project
Client
China Southern Power Grid Co., Ltd. Extra High Voltage Transmission Company (EHVTC)
Project Name
AT500-E Intelligent Lock Management System for 500kV Yong'an Station, Pingguo Station, Chongzuo Station, and Yulin Series Compensation Station
Scale
4 substations, 2,700 locks (padlocks, anti-theft door locks, cabinet locks, escape locks, handle locks, and cylindrical locks)
Challenge
The Extra High Voltage Transmission Company (EHVTC) is a subsidiary of China Southern Power Grid, responsible for the main power transmission framework of the Western Electricity to Eastern China. It covers five provinces and regions — Guangdong, Guangxi, Yunnan, Guizhou, and Hainan — making significant contributions to the healthy, rapid, and sustainable development of these regions. With the rapid growth of its business, the company faces the following challenges in daily operation and maintenance:
Inadequate Lock Management: The large number and variety of locks make unlocking time-consuming, affecting operational efficiency. Universal keys can lead to accidental operations, and civilian-grade locks are prone to corrosion outdoors and cannot record unlocking operations.
Inadequate Key Management: The vast number of keys makes them difficult to locate, carry, and prone to loss. Borrowing records are mostly handwritten and hard to preserve long-term. In unattended substations, keys can be easily lost or duplicated, posing significant security risks.
Solution
To address these challenges, EHVTC introduced our AT500-E Intelligent Key and Lock Management System, which features the following capabilities:
Authorized Unlocking: Only authorized personnel can unlock within specified times and areas, ensuring operational safety.
Intelligent Lockout: The system automatically rejects unauthorized operations, preventing accidental actions.
Management Traceability: All unlocking operations are recorded for easy post-event tracing and accountability.
Outcome
Increased Efficiency: A single intelligent key replaces all mechanical keys, significantly reducing unlocking time and enhancing operational efficiency by 50%.
Enhanced Safety: Authorization-based unlocking ensures that unauthorized access is denied. The system records all operations, preventing safety risks caused by accidental entry or operations, reducing safety incidents by 30%.
Effective Management: All unlocking activities are documented, and access behaviors are fully controlled, eliminating security hazards caused by poor key management, resulting in a 40% reduction in key management-related issues.
