“…Normally, the DTS system is used for temperature monitoring and estimation of real-time ratings of transmission cables [1][2][3][4]. However, it is not suitable for underground distribution cables because a distribution cable network is more complex than a transmission cable.…”

Abstract:With power systems switching to smart grids, real-time and on-line monitoring technologies for underground distribution power cables have become a priority. Most distribution components have been developed with self-diagnostic sensors to realize self-healing, one of the smart grid functions in a distribution network. Nonetheless, implementing a real-time and on-line monitoring system for underground distribution cables has been difficult because of high cost and low sensitivity. Nowadays, optical fiber composite power cables (OFCPCs) are being considered for communication and power delivery to cope with the increasing communication load in a distribution network. Therefore, the application of distributed temperature sensing (DTS) technology on OFCPCs used as underground distribution lines is studied for the real-time and on-line monitoring of the underground distribution power cables. Faults can be reduced and operating ampacity of the underground distribution system can be increased. This paper presents the development and improvement of an intelligent cable monitoring system for the underground distribution power system, using DTS technology and OFCPCs as the underground distribution lines in the field.

“…By this, the load can be controlled that way that the GIL is applied with the maximum possible overloads. Similar systems for HV cables are known as "Real Time Thermal Rating" systems [7,8,9].…”

“…For instance, local soil moisture and soil temperature, insolation, wind speed or humidity can be measured locally and the relevant data can be transferred to the control centre via RTU. At the centre the data serve as input data for the thermal rating system The thermal rating system works similarly but yet different to the RTTR system described in [7]. Similarly temperatures and currents (by CTs) of the lines are measured and fed into the software.…”

Gas Insulated Transmission Lines are designed for underground bulk power transmission. They may be used to overcome potential bottlenecks in EHV transmission grids. They are designed for high ampacities and have high overload capabilities. By exploiting the latter, a load scheduling in the grid becomes easier. To do so the thermal status of the GIL has to be known. A temperature measurement system was developed and tested which allows an online measurement of the conductor temperatures during operation, enabling scheduling and handling of overloads.
