Description

Technical Field

[0001] This invention relates to the field of dynamic real-time monitoring technology for power grid systems, specifically a real-time dynamic monitoring and anomaly response system for the operating status of a power grid. Background Technology

[0002] With the continuous development and intelligent upgrading of power grid systems, the operating environment of power systems is becoming increasingly complex. The safety, stability, and reliability of distribution rooms and related facilities have become one of the core issues in power grid operation and management. In traditional power grid monitoring systems, many important environmental parameters, such as temperature, humidity, power quality, and gas leaks, rely on manual inspections and periodic checks, making real-time monitoring and dynamic response impossible. Because power grid facilities may be subject to various interferences during operation, such as environmental factors and power quality fluctuations, safety hazards such as equipment failures, fires, and gas leaks may occur, directly affecting the safe and stable operation of the power grid.

[0003] While existing power grid monitoring technologies have made progress in some areas, they generally suffer from insufficient data acquisition, monitoring accuracy, anomaly response capabilities, and system integration. In particular, when facing potential risks such as temperature and humidity changes in substations, SF6 gas leaks, and power quality fluctuations, existing systems often fail to handle and respond promptly and effectively, leading to reduced safety and reliability of power grid operation. No solutions have yet been proposed to address these technical problems. Summary of the Invention

[0004] To address the problems in related technologies, this invention proposes a real-time dynamic monitoring and anomaly response system for power grid operation status, overcoming the aforementioned technical issues in existing technologies. The purpose of this invention is to monitor key parameters such as temperature and humidity in the distribution room, SF6 gas leakage, and power quality in real time, ensuring that power grid equipment remains in a safe and stable state during operation, promptly detecting potential faults, and simultaneously monitoring fire early warning signals such as smoke and aerosols. It also enables rapid response through automatic control functions such as ventilation and aerosol fire suppression to prevent fires. The data gateway cleans and detects anomalies in the collected raw data, enabling timely identification and handling of potential issues. In case of abnormal situations, this system avoids incorrect judgments and responses due to data quality issues, improves the overall accuracy and stability of the system, optimizes data transmission processes, and enables data to be transmitted quickly and accurately from the field to the system platform. This reduces delays and errors in information transmission, improves the timeliness of remote monitoring and response, centrally stores reported data, and allows for in-depth data analysis and visualization. This helps maintenance personnel intuitively understand the power grid's operating status, improves fault diagnosis and decision support capabilities, and effectively reduces the workload of manual inspections and responses by comprehensively monitoring the power grid's operating status, detecting abnormal situations in real time, and responding quickly. This improves the efficiency and intelligence level of power grid operation.

[0038] Environmental monitoring module 100 is used to collect temperature and humidity data of the power distribution room in real time and monitor SF6 gas leakage.

[0039] Power quality monitoring module 200 is used to collect data from instruments in the power distribution room and monitor the operating status of power grid equipment.

[0040] The fire alarm control module 300 integrates smoke detection, ventilation, aerosol fire suppression, audible and visual alarms, and SMS notifications.

[0041] Data gateway 400 is used for data cleaning, anomaly detection and processing, and sending data to system platform 500;

[0042] System Platform 500 is used for centralized storage, in-depth analysis, and visualization of reported data.

[0043] The video monitoring module 600 connects to an NVR recorder and various cameras via wired or wireless means to monitor the power distribution station, transmit video data in real time, and supports PTZ control and screen magnification.

[0044] The environmental monitoring module 100, power quality monitoring module 200, fire alarm control module 300, and video monitoring module 600 are connected to the data gateway 400 through a communication network.

If the monitoring data is abnormal, the system will automatically start the relevant equipment for adjustment or alarm.

[0051] In this embodiment, the temperature and humidity sensor monitors the temperature and humidity in the power distribution room. When the temperature is below the minimum value, the air conditioner is remotely controlled to heat the room. When the temperature is above the maximum value, the air conditioner is remotely controlled to cool down the room. When the temperature returns to normal, the air conditioner is turned off.

Once the threshold is exceeded, the audible and visual alarm will sound, and staff will be notified promptly via SMS or telephone for handling. Staff can remotely control the aerosol fire extinguisher with a dual-control switch to extinguish the fire, connecting the alarm device and the fire extinguishing device. In case of fire, short circuit, or other abnormal situations, the circuit breaker can be remotely controlled to disconnect the line, thus protecting the line.
