Description

Power Facility Image Providing Method and System with SCADA Event Information

The present invention relates to a method and system for providing images of power equipment using SCADA event information, which provides real-time image information to workers when event information received from SCADA meets filtering conditions.

Most of the recently constructed unmanned substations are remotely monitored and controlled at the dispatch branch, and an automation system is operated to monitor and control the site at the unmanned substation.

In other words, the recent substation automation system has a function to manage power quality from simple power monitoring and control functions in the past, a function to diagnose the online status of facilities and predict life span, manage facilities from disasters, and protect substations from intruders. By adding a security disaster prevention function to protect, it is developing into an advanced active intelligent system rather than a passive or simple system.

Accordingly, when an abnormality occurs in various process management systems, it can be automatically reported to the relevant authorities or related persons, and emergency relief is automatically processed using remote communication in the event of a fire, equipment failure, or motor operation problem. Efforts to reduce manpower waste, such as having to have full-time workers on standby for the management of the device, by automatically notifying the management center, etc. are emerging.

However, since most control facilities have a large number of sensors and motors installed according to the trend of unmanned and automated, it is essential to observe their operation status and respond promptly, so a full-time worker must be assigned. Therefore, in the event that a full-time worker at the site needs to take immediate action in the event of various abnormalities, but is not aware of this situation, or the distance between the motor and the on-site control panel is large, the actual rotation speed of the motor or abnormal operation noise during startup can be directly detected. There is a difficulty that cannot be heard.

In Korea, SCADA (Supervisory Control And Data Acquisition) technology is used to operate unmanned substations. However, as the SCADA facility is a major information and communication infrastructure, it is stipulated by the law that a physically separated network such as a CCTV network should be used. The unmanned substation monitoring information system checks whether there is an actual fire or not. That is, the two systems are operated separately.

In these general environments, a system that automatically provides unmanned substation image information to a manager (worker) is required for quick and accurate situation determination.
