Design and analysis of power evacuation system for solar power-plant

Abstract

Six solar power plants on a canal are considered. 2.88-4.32 MW power is generated at each of the canal solar power plant at 3.3kV and power from all the six solar power plants is evacuated at the main receiving substation among them. The power is generated at 3.3kV voltage level and collected at 11kV at the main receiving substation. Further the received power at 11kV is stepped up to 66kV using switch yard and then dumped into the state grid. The process of collecting the power and dumping it into the desired load center is known as power evacuation. Cable is taken of 11kV and substation will be of 11/66kV. The power flow simulation for this non-conventional energy power plant is done using ETAP software. The simulation is done in order to find the power generation losses, power availability, reliability, tentative cost and efficiency.
