With the continuous improvement of the degree of social informatization, the number of equipment used for remote control, telemetry, remote adjustment and other aspects in the distribution room is increasing day by day, and its environmental equipment is also increasing, and the environmental equipment in the distribution room (such as indoor air conditioning, dehumidifier, fire protection system, security system, water leakage detection system, etc.) must always provide a normal operating environment for the power equipment in the distribution room, therefore, it is particularly important to establish a comprehensive power environment monitoring system for the transformation of the distribution room.
According to the long-term operation environment requirements of the main indoor equipment of the State Grid Corporation of China 10 35kV and the relevant management regulations of substation operation, the environmental requirements of the distribution room in the substation include:
The existing conventional power distribution room that has been built is not equipped with a comprehensive power environment monitoring system in the distribution room, the environmental parameters in the distribution room do not consider the data acquisition and monitoring, and the environmental control in the distribution room adopts manual control mode, and the operation personnel control the distribution room environment in place by manually controlling the air-conditioning operation mode, fan start and stop, shutter switch and other ways in the distribution room according to the external environmental conditions, and can not realize automatic control and monitoring.
In view of the current situation of the operating environment of the distribution room, it is necessary to configure a set of HT500 comprehensive monitoring device for the distribution room in the distribution room, which includes an environmental data acquisition unit, an environmental control (temperature and humidity) unit, a lighting control unit, a fire alarm and fire protection system interface and an integrated intelligent control and management platform, so as to collect, process and upload the temperature, humidity, water immersion, SF6 concentration and other environmental information in the distribution room in real time, and realize the environmental status, air conditioning, fan and lighting and other auxiliary facilities in the distribution room. Monitoring, according to various environmental conditions and operating environment requirements, the linkage of auxiliary equipment in the station is realized through the integrated environmental management platform, and the environmental intelligent control of the substation station is completed.
Overview
1) Global operation: Real-time refresh of fault status.
2) Display of important environmental indicators (temperature and humidity, SF6 concentration, water level) and warning of exceeding standards.
3) Alarm events are refreshed in real time and jump query is supported.
Environmental monitoring
1) Sensors (temperature and humidity sensor, SF6 gas detector, water level sensor) data are refreshed in real time.
2) Normal abnormal status display.
3) Threshold setting and sensor configuration of environmental quantity.
Device control
1) Equipment (air conditioner, fan, water pump, dehumidifier, light) operation stop status display.
2) Manual control of equipment (air conditioner, fan, water pump, dehumidifier, light) on and off.
3) Automatic control of environmental volume linkage equipment (air conditioner, fan, water pump, dehumidifier, light).
Access control
1) Authorization, access control status inquiry, door opening control.
2) Records and exception records are queried.
3) Open the door linkage capture and video.
Fire alarm
Monitor indoor fires, send out alarm information in time, control fire hazards in the early stage, and reduce possible losses.
Monitoring
1) Image surveillance, cruising, occlusion detection, etc.
2) Support gimbal control function and support playback.
3) Linkage with access control, anti-theft, fire and other warning information.
Security precautions
1) Intrusion alarm, monitoring doors, windows and other parts, with first-class monitoring equipment, to prevent illegal entry and destruction of equipment and facilities in the power distribution room.
2) Invasion linkage**.
3) Support manual, automatic, arming, and disarming.
After the completion of the intelligent environmental monitoring system of the power distribution room, the operation and maintenance monitoring and emergency response capabilities will be significantly improved.
1) Holographic monitoring to achieve lean operation and maintenance of power grid equipment
Through the unified monitoring of temperature, humidity, SF6, oxygen, ozone, water level, lighting control, air conditioning control, access control, and cameras in the distribution room, the holographic grasp of the operation status and health level of power grid equipment can realize the lean operation and maintenance of power grid equipment.
2) Multi-level linkage to strengthen the safety protection of the power distribution room
Through access control monitoring, infrared double identification and camera linkage, record foreign intruders, start the sound and light alarm device, remind the monitoring personnel to stop in time, and strengthen the security protection of the distribution station room.
3) Visual command to improve the ability to respond to sudden failures
Through the first monitoring, in the power distribution room sudden failure, the first time to understand the on-site situation, command the on-site fault handling, improve the emergency response ability of sudden failure.
4) Remote inspection to reduce the cost of operation and maintenance personnel
Remote inspections replace daily on-site inspections to reduce O&M and time costs, and reduce the workload of O&M personnel.
