Research on the centralized monitoring and command system of cable network

The centralized monitoring and command system of cable network which is based on the urban power distribution network achieves centralized display the comprehensive information of cables, combining with the cable distribution information, the data of production management, the scheduling data of SCADA (Supervisory Control and Data Acquisition) system, the monitored cable information, the monitored environmental information of cables, the information of cable spare parts and so on. It uses GIS (Geographic Information System) of the power grid as a basic displaying platform. The data model of centralized monitoring is established, in order to dynamically track the operating status of the cable. The Drools rule engine is used to achieve concentrated early-warning and alarm of the operating conditions of cables and tunnels. The maximum and current carrying capacity of cables is obtained by the analysis and calculation of monitoring data and load scheduling data, on the basis of which the dynamic adjustment proposals of carrying capacity are given. Besides, we implement the patrol plans and task management of cable network and emergency command system of cable tunnels, and translate the traditionally extensive mode of cable operation and management into the one which is "specialized, meticulous, automated, intelligent and standardized".
