Abstract

The invention discloses a multifunctional power cable fault location online monitoring system. Fault detection devices are arranged on a bus, and one fault detection device is arranged for every 28 km; the fault detection devices communicate with a fault location host wirelessly; the fault location host communicates with a backstage management server via a GPRS wireless network; and timing is carried out on the fault detection devices, the fault location host and the backstage management server via a GPS system. By adopting traveling wave and ultrasonic wave fault detection and location technologies, short circuit and grounding fault of the cable can be detected, local discharge fault can also be accurately judged, and real-time online monitoring and remote control can be realized.

Description

technical field [0001] The invention belongs to the field of smart grids, in particular to an on-line monitoring system for multifunctional power cable fault location. Background technique [0002] Under the guidance of the purpose of "developing the economy, power first", China's electric power industry is developing vigorously. The continuous expansion of power system capacity, the continuous increase of voltage levels, and the continuous construction of new transmission and distribution lines have made the power grid increasingly complex. The detection of faults and the quick action of relay protection put forward higher requirements; especially the fault detection and location of cable lines is the most complicated. Contents of the invention [0003] In order to solve the technical problems of inaccurate cable fault location and single fault detection type judgment by current devices, the present invention proposes a multifunctional power cable fault location on-line m...
