| High voltage cable and power cable tunnel is the main artery of the city center area, what play a crucial role to the security of the whole city power supply.Because of the rapid growth of equipment quantity, the operation and maintenance’s pressure of high voltage cable and power tunnel is bigger and bigger. One reason is the personnel quantity of cable operation and maintenance is limited, what is impossible to keep pace with the number of devices. In the traditional management mode, it will result in the equipment quantity and range of the single management worker increase greatly.The second reason is the cable and the cable channel’s monitoring technology is lack,or the monitoring method is single. The third reason is the various monitoring technology according to the cable or cable tunnel is running state of self-organizing system and unrelated. The same type of monitoring equipment just monitor only one or several cable and cable channel, the correlation degree is very low. All kinds of cable and tunnel status monitoring system of equipment parameters, geographic information data, power supply system, cable load data as information support. In this case, even if the the cable and channel condition monitoring techniques increased, it’s just only a monitoring information island one by one, can not play the role fully.The research based on the integration of high voltage cable network operation monitoring system architecture, research for cable temperature monitoring, tunnel of Beijing high voltage cable network operation and management of access control and video surveillance, high voltage cable and power tunnel multi-parameter monitoring front-end of on-line monitoring, monitoring system and process, and application in the Beijing high voltage cable network, the information data cable network equipment, spatial information, power supply system as a support, a cable network monitoring information isolated island together, will be a variety of cable network running status monitoring system integration should be used, to carry out a full range of monitoring work, gradually realize the condition based maintenance of cable network system, the formation of new cable operation management mode. |
