Load flow analysis of Industrial plant

Abstract

The Power-system analysis is mainly performed to predict or enhance the performance of an existing systems
or system is being plan. Design of the industrial power system is slightly different from radial power systems. It is
performed to fulfill different objectives of industrial plant namely safety, reliable service, high-power quality, and low
capital and operating costs. To plan the industrial power system, different kind of power system analysis are required
such as low flow analysis, short circuit analysis, relay coordination, motor starting analysis, power factor corrections,
stability analysis etc. In this paper, the load flow analysis of 6.6 kV industrial plants is presented using Electrical
Transient Analysis Program -7.5.5(ETAP). Load flow is conducted using NR Method. The plant is supplied from the in
plant generation (2*16.5 MW Existing and 11.8 MW-newly installed). The external grid supply is used for black start of
TG’s.17.5 MW of existing load become 24 MW after expansion. So this study is done for check feasibility of load and
generation surplus and operating philosophy selection.
