Abstract
At present, the system wiring method and construction in the photovoltaic power plant area are arbitrary and many design schemes reflect the designers' own habit. In addition, the economic benefit of different cable laying routes and method is not considered in the design stage. To solve these problems, the connection type, length proportion and cable specification of the primary system in the photovoltaic power plant area are scientifically optimized or selected and the expectation formulas of economic indicators for a variety of photovoltaic power stations are proposed on the basis of theoretical analysis; the mathematical and statistical calculation and enumeration method assisted with computer software are employed to obtain the recommended value of wiring lengths of various cables in this paper. Oriented to the three indicators in connection with cables, i.e. minimum installation cost, maximum total system revenue and minimum Levelized Cost of Energy (LCOE), and taking the selection specification, value and construction cost of cables as the input conditions, these expectation formulas can automatically generate the CAD wiring diagram and cable inventory according to the finally summarized computer operation logic diagram under the conditions where the corresponding computer software is obtained presumably, so that the technical data such as final output design drawing and cable inventory will be the most economic design scheme as expected by the formulas. Furthermore, in the process of theoretical analysis, some variables and principles present in the formulas are reasoned, calculated and demonstrated in a scientific way and the theoretical basis herein is improved accordingly. Introduction of theoretical formulas can guide the computer software developers to write programs for the schemes herein and finally work out cabling design software oriented for optimization of economic benefit for photovoltaic power plant areas.
