Augmentation of Power Distribution Plant

Abstract

Power-flow or load-flow studies are very helpful for the designing and the future expansion of power systems. Also it is very helpful for getting the best output for the operation of existing systems. It is also having to find out the set of voltages: magnitude and angle, network impedances that creates the load flows they are known as the exact at the system terminals. So, this theory is useful to augmentation of power distribution network of Petronet LNG plant. It is planned to expand terminal capacity from existing 10 MMTPA to 15 MMTPA (Phase-3A) and further up to 17.5 MMTPA (Phase-3B). There are two option for augmentation of power distribution system. Addition of two nos. of transformers are needed to supply further power requirement. Study for augmentation of two no. of grid transformers of 40 MVA 220/11kV or 220/33kV of suitable rating as pr load details provided by PLL. Selection and percentage impedance and calculation to be selected so that fault level of the existing system does not increase. Rating to be selected for transformer is 40 MVA, 220kV. The secondary voltage selection will be the recommendation based on study.
