Collecting Power Lines Research of Large-Scale Photovoltaic Power Station

For the large-scale photovoltaic power station, the voltage grade accessing the system is generally over 66kV. Because of large area groupware arrangement and high cost collecting power lines, it is difficult to make a choice between the voltage grade of 10kV and that of 35kV. Through setting up one 200MW photovoltaic power station model, analyzing and comparing the investment and losses of setting up collecting power lines of the two kinds of voltage grades concretely, this paper obtained the excellent plan to provide references for the design of photovoltaic power stations.
