Problems solved by technology

However, there is currently no effective technical means to monitor the operating status of cables in operation, and there is no effective real-time detection means and early warning mechanism for faults; and for safety reasons, cables in operation often work under extremely conservative carrying capacity. capacity is wasted
However, there is a great risk in blindly increasing the maximum operating current value of the cable, and the dispatching department of the power grid company dare not try it lightly

Abstract

The invention relates to a management method of intelligent cable state online measurement and control. The management method comprises the following steps that S1, cable temperature data are obtained, state monitoring and control in real time are conducted, and an original temperature database is established; S2, ampacity adjustable and controlling logic is started off, the utilization rate of ampacity is analyzed, and dynamic capacity increasing is obtained; S3, the cable fault location analysis is conducted and an early warning is carried out; and S4 a life cycle of a cable is analyzed anda conclusion is obtained. The invention has the advantages that cable fault early warning, testing, location and navigation are obtained, dynamic capacity control is operated, full life cycle aging states are evaluated, and management and maintenance guidance functions are operated by a cable system.

Description

technical field [0001] The invention relates to an online monitoring and control management method for the state of an intelligent cable. Background technique [0002] With its many advantages, XLPE power cables have been widely laid in the domestic power grid system, and there will be a further growth trend in the future. However, there is currently no effective technical means to monitor the operating status of cables in operation, and there is no effective real-time detection means and early warning mechanism for faults; and for safety reasons, cables in operation often work under extremely conservative current carrying capacity. Capacity is greatly wasted. However, there are great risks in blindly increasing the maximum operating current value of the cable, and the dispatching department of the power grid company dare not try it lightly. The invention proposes an intelligent cable measurement and control system for real-time monitoring of the operation status of cable ...
