Advanced disaster prevention systems for power generation and substation facilities
In the power and energy industry, traditional power plants are still the main source of electricity worldwide. Electricity is transmitted from power plants through high-voltage grids to substations in different regions, where the voltage is converted and reduced to meet the needs of residential, industrial, and other users. EGAT, one of the top three power companies in Thailand, foresaw a massive growth in nationwide electricity demand over a decade ago. Therefore, they have placed great emphasis on power stability and safety, especially in substations, which directly impact users. Ensuring the normal operation of equipment and disaster prevention safety within substations is a crucial issue. Substations typically consist of transformers, transmission lines, switchgear, capacitors, reactors, and other related equipment. Large transformers require high and spacious indoor areas for placement and cooling, posing challenges for the installation and response time of traditional fire detectors in such spaces. Consequently, EGAT adopted the concept of "prevention over cure," integrating the "GKB Technology - Ultra-Early Active Notification" Disaster Prevention System to complement the blind spots of traditional fire detectors.

Client Needs
- Protecting important power generation equipment to avoid major fire losses.
- Integrating with the existing Honeywell disaster prevention system for multiple detections.
- Enhancing automated disaster prevention mechanisms and actively notifying personnel in the central control room.
Key Issues
- Traditional fire detectors struggle to effectively detect fires in high and spacious indoor areas.
- Large transformer facilities are placed in non-enclosed or non-dust-free environments, making it impossible to use air sampling for fire detection.
- Large transformers are critical substation facilities, requiring intensive manpower for inspection.
Solutions
- Implement the VFDS (Video Fire Detection System), simulating human eyes to observe the 3D spatial environment. Upon detecting anomalies, the system actively reports and supports traditional detectors for dual protection.
- Personnel in the central control room can monitor the transformer area through live images from the VFDS. When personnel are not in the control room, they can still receive active notifications of abnormal events.
- Provide an electronic map for quick identification of the location of anomalies.
