With the large-scale grid integration of green energy, the power grid operating environment is undergoing structural transformation, posing significant challenges to the steady-state balance of traditional substations. Against this backdrop, Dingxin Smart Technology has introduced the DX-BTS100 Substation Online Monitoring Series. This integrated solution combines substation video and environmental monitoring systems, intelligent comprehensive auxiliary monitoring systems, and infrared temperature measurement systems to establish a comprehensive, intelligent, and multi-dimensional substation safety protection framework. It enables three-dimensional reconstruction of substation operational states and facilitates intelligent takeover of monitoring functions.
I. Limitations of Traditional Substation Inspection Methods
1. Traditional inspection methods heavily rely on manual on-site verification at regular intervals, meaning that sudden defects such as momentary overheating or flashovers occurring between inspections are difficult to detect promptly.
2. Inspection personnel must work in close proximity to high-voltage energized areas, posing significant risks. Additionally, manual temperature measurements using handheld devices are highly susceptible to weather conditions, viewing angles, and individual experience. This leads to potential subjective biases or missed readings in data recording, making it difficult to achieve pixel-level comprehensive and precise measurements.
3. Inspection results are predominantly recorded on paper or stored as fragmented electronic documents, lacking continuous digital trend analysis. Furthermore, as the number of substations increases, manual inspections face management bottlenecks such as soaring labor costs and inefficient repetitive tasks.
II. Substation Online Monitoring Series
1. Substation Video and Environmental Monitoring System
The substation video and environmental monitoring system utilizes high-definition video imaging, environmental sensing, and intelligent analysis to enable remote equipment status monitoring, environmental anomaly alerts, and automated operations and maintenance management, providing comprehensive safeguards for the stable operation of power systems.
The system is equipped with day-and-night surveillance cameras that accurately capture the visual status of equipment such as transformers and circuit breakers, enabling remote verification of switch operations, instrument readings, and battery performance. It also integrates motion detection, video tracking, and zone monitoring capabilities to automatically identify abnormal activities. For environmental monitoring, the system continuously collects critical metrics like temperature, humidity, wind speed, and water ingress to ensure equipment operates within standard parameters. It supports remote camera control and voice intercom, preventing operational conflicts and enhancing emergency response efficiency. Furthermore, the system features multi-level alerts: hardware/software failures and environmental anomalies trigger real-time reporting with audible/visual warnings and SMS notifications. Critical areas undergo 24/7 recording with a 30-day storage cycle for incident review. It integrates access control monitoring and station guard functions to reinforce entrance/exit security. Remote parameter adjustments via master station commands significantly reduce on-site maintenance needs, driving substation operations toward unmanned, intelligent transformation while markedly enhancing power system safety and response efficiency.
2. Intelligent Integrated Auxiliary Monitoring System for Substations
The Intelligent Integrated Auxiliary Monitoring System for Substations combines environmental monitoring, video patrols, smart control, and security protection. By deploying sensors for temperature, humidity, water leakage, smoke detection, and arc flash, alongside AI cameras featuring facial recognition, auto-tracking, and Smart event detection, it enables real-time perception of substation operational status and synchronized data playback. The system leverages built-in high-current relays to enable remote or automatic interlock control of equipment like fans and water pumps. On the security front, it integrates technologies such as electronic fencing and dual-sensor infrared detection to establish a multi-layered defense. Combined with a facial recognition access control system, this enhances real-time management capabilities and access security for unmanned substations.
3. Substation Infrared Temperature Measurement System
The system employs infrared thermal radiation conversion technology, utilizing high-precision detectors to capture infrared energy emitted by electrical equipment. An optical scanning mechanism focuses the thermal distribution pattern onto photosensitive components, which are then processed into visual thermal images through optoelectronic signal conversion. Employing non-contact real-time monitoring, the system dynamically analyzes pixel-level temperature data to accurately identify and pinpoint overheating hazards without disrupting equipment operation.
In practical applications, Dingxin Smart Technology's substation online monitoring series has been widely deployed across the State Grid. Leveraging intelligent monitoring and precise early warning capabilities, it has significantly enhanced operational efficiency. This product line not only provides robust data support for grid decision-making but has also become a cornerstone in ensuring the safe and stable operation of the power grid.
