Substation auxiliary monitoring system main functions

Substation auxiliary monitoring system main functions include: monitoring the normal operation of important equipment in substations; accidents and emergencies with the monitoring center of the audio and video communications; and some auxiliary monitoring and control functions related to substation production and operation. The scope of coverage includes: fire monitoring; environmental monitoring (temperature, humidity, flooding, wind speed, rainfall, etc.); remote query and linkage control of the operating status of the power support (air conditioning, fan, lighting system) at the station end; networked access control system Control station personnel access, infrared radiation, electronic enclosures and other perimeter to prevent access, to ensure the effective protection of substation construction and equipment safety.

The typical linkage function is as follows:

Linkage with the fire protection system: When the fire alarm occurs on the site, link the live video and lighting control, and accurately understand the situation on the spot;

Environmental monitoring and linkage: monitoring the environmental conditions of substations, including temperature, humidity, flooding, and other information, and linkage of air-conditioning, dehumidifiers, fans and other equipment;

The access control system records and manages personnel entering and leaving the station;

Wind speed, rainfall meteorological sensors and water leakage cables collect on-site meteorological information in real time. When certain conditions are met, risk warnings are performed.

Indoor and outdoor lighting lighting remote control, auxiliary video surveillance system night camera effect;

Through the linkage of cameras and lights, the operation status of indoor and outdoor venues and important equipments in substations are monitored;

In the event of emergencies, the two-way audio and video surveillance exchange between the substation and the monitoring center.

Walls, gates, etc., through cameras, infrared probes, electronic fences and other equipment to prevent illegal entry;

Install alarm probes in building windows and doors, such as door magnetic, infrared, and glass break detectors;

Linkage with sound and light alarm devices;

Based on the construction of substation video surveillance systems in the early stage, a substation (substation)-regional master interconnection architecture was formed.
