Three-Terminal Transmission Line Protection By Considering Effect of Infeed Current
https://orcid.org/http://orcid.org/0000-0002-4985-1960
The intermediate connection between load and generation unit is cost-effective as it does not require an extra substation and associated equipment. Renewable energy sources are the best choice for employing an intermediate connection to load and generation units. The design of such three-terminal transmission line having an infeed current behind the tap point demanded careful settings of the relay. In this work, the distance protection scheme on the 132 kV transmission line is investigated to consider the effect of infeed current from renewable energy sources. In the research, it found that the traditional three-step distance protection settings encountered serious issues of under-reach. The proposed method provides primary protection and backup protection to a multi-terminal transmission line without tap information. Pre-calculated data using PMU such as infeed current, the compensated constant, and positive, negative, and zero sequence components of electrical quantity are used by the local distance relay. The simulation results on the three-terminal line system and modified IEEE 9 bus system show that the algorithm is faster, more accurate, more cost-effective, and more reliable than the existing zones of the protection method.
