DESIGN OF SYSTEM OF CONCENTRATOR PHOTOVOLTATIC PLANTS

摘要

FIELD: power engineering.;SUBSTANCE: system of concentrator photovoltatic plants comprises Sun-tracking concentrator photovoltaic plants arranged in the form of a rectangular lattice with a distance X_ns between neighbouring concentrator photovoltaic plants in direction from the north to the south and the distance X_we between neighbouring concentrator photovoltaic plants in direction from the west to the east, at the same time distances X_ns and X_we satisfy the following ratios simultaneously: X_ns ≥ (a² +b²)^1/2, m; X_ns ≥ 0.0105 · φ + 1.42, m; X_we = B · S_lp / X_ns, m; where a - length of a light-perceiving surface of a concentrator photovoltaic plant, m; b - width of a light-perceiving surface of a concentrator photovoltaic plant, m; φ - geographic latitude of the place, °; B=0.0026·φ²-0.0584·φ+4.047 - non-dimensional coefficient for detection of the earth area required for placement of 1 m² of the light-perceiving surface of the concentrator photovoltaic plant; S_ne - area of the light-perceiving surface of the concentrator photovoltaic plant, m²; and the earth area S_se for placement of the system of concentrator photovoltaic plants meets the following ratio: S_se=N·B·S_lp, m²; where: N - number of concentrator photovoltaic plants, pcs.;EFFECT: system makes it possible to provide for maximum efficiency of conversion of arriving radiation into power with permissible losses of energy as a result of shading, and minimum area of earth surface required for placement of a system of concentrator photoelectric plants.;6 cl, 8 dwg
