Enhancement of Power Transfer Capability of Transmission Line using HTLS Conductor
Keywords:
HTLS, INVAR, Ampacity.Abstract
In India, ACSR and AAAC are most commonly used conductors for power transmission through overhead conductors. To meet the increased load demand either we need to construct the new UHV or EHV line or to upgrade the existing transmission line. Upgrading of transmission lines means the modifications in the existing transmission line to enable the increased current flow limits, but making a new transmission lines also have few major constraints i.e. ROW constraints (Lack of availability of land/corridors for construction of new transmission lines) and time constraints (due to short time schedule for the construction of transmission lines projects need to match with generation projects).To avoid such difficulty we need use a high performance conductor known as HTLS (High Temperature and Low Sag) conductor, which can carry approximately 2 to 2.5 times higher current that of conventional ACSR conductors of same size and it can be easily operated at higher temperature level (above 200°C) whereas the thermal limit of ACSR conductors is 85°C,hence by increasing the thermal limit the current carrying capacity can be enhanced.
