The safety monitoring system of existing substation has the situation that platform redundancy, dispersion, and cannot share information, in view of this problem, this paper designed an intelligent substation online secure monitoring system based on IEC61850 standard which includes perimeter security monitoring subsystem, electrical equipment online temperature monitoring subsystem, and substation security information management subsystem. The paper modeled unified information out of substation perimeter security information and equipment temperature information in accordance with IEC 61850 standard, and achieved an integration security measurement system platform. The system uses laser fence to detect and locate the intruder, IP cameras for remote monitoring and intrusion evidence collection, SAW temperature sensor for temperature measurement. It implements to monitor automatically perimeter security intrusion information and temperature information in real time, to provide a strong technical support and engineering reference for the development of intelligent substation.
