The control method of the two-axis tracking configuration polar coordinate system PV

The method of controlling the structure of a two-axis tracking PV polar coordinate system, belonging to the technical field of solar power generation, characterized in that it is a control method of the structure is: (1) setting an initial value; (2) Calculate n, δ; (3 ) calculated ωsr, ωss, tss, tsr; (4) calculating tz, tz≥tsr, is executed (5), otherwise, return (4); (5) overcast, the return (5), otherwise, performing (6); (6) touch the limit switch, that the structure is stopped, otherwise, the process (7); (7) [gamma] s is calculated, the adjustment αs, γs, performing (8); (8) Comparative R2, R2 ', R2 ", R2" ', R2 = R2' = R2 "= R2" ', is maintained αs, γs, performing (13), otherwise, the process (9); (9) R2 ≠ R2' ≠ R2 "≠ R2 ' ", is sequentially adjusted αs, γs, performing (13), otherwise, performing (10); (10) R2 = R2' ≠ R2" = R2 " ', is adjusted aS, performing (13), no, performing (11); (11) R2 = R2 "≠ R2 '= R2"', is combined S adjustment [gamma] s, execution (13), otherwise, performing (12); (12) Looking Rmin of, successively adjust αs, γs performing (13); (13) Δt ended is performed (14), otherwise return (13); (14) tz≥tss, that the structure is stopped; NO, execution (5).
