Embodiment Construction
[0035]In this example, the Sky Mirror in the Spanish PS10 Tower Solar Hot Power Station Mirror Mirror is optimized, and the overall method process isfigure 1 Indicated. The specific parameters of the power station are listed in Table 1, the mirror layout is likefigure 2 Indicated.
[0036]Table 1 Mark field parameters in the embodiment
[0037]
[0038](1) Establish a multi-objective point focus optimization model of fixed day mirror field. Set up 16 rectangularly arranged focus target points on the receiver plane, the location of the target point isimage 3 Indicated. The sampling point when calculating the energy distribution is also used in rectangular arrangement, 20, specific positions such asFigure 4 Indicated. At each scheduled moment of the mirror field, the correspondence between each surface day mirror and the target point in the mirror field can be determined that the decision variable of optimization problem can be represented as 0-1 variable z.h, a , When the focus target point o...
