Abstract

This study introduces a cutting-edge solution to improve safety in substations through a real-time anti-maloperation system utilizing the IEC 61850 framework. Conventional anti-maloperation systems, largely microcomputer-based, face challenges including offline operational limits and cumbersome setup procedures, which compromise their efficiency and real-time functionality. This research explores these issues and demonstrates how the IEC 61850 standard, particularly its GOOSE messaging, can overcome these hurdles. Our analysis of the proposed real-time system showcases its superiority in functionality and technical advantages compared to existing solutions. We provide a comprehensive examination of its design, locking mechanisms, and deployment tactics, offering solutions to the drawbacks of traditional systems. By incorporating IEC 61850 and GOOSE messaging, the system enhances operational efficiency and ensures continuous monitoring and control, drastically improving the reliability and efficiency of substation anti-maloperation strategies. This novel methodology represents a significant leap forward in substation automation and safety management, offering a forward-looking perspective on safeguarding substation operations.
