摘　　要：根据光学特性,建立抛物槽式聚光器的光学模型,分析焦距、几何聚光比、开口宽度和跟踪误差等参数对聚光特性的影响规律。在此基础上,建立光学特性优化数学模型并将粒子群优化算法和蒙特卡洛法相结合,提出给定几何聚光比和跟踪误差情形下的光学参数的优化设计方法。计算结果表明,当抛物槽边缘半角为45°时,光斑偏移量最小。Optical model was established based on optical character of trough CPV collector and the effect of focus length, geometrical concentration ratio, opening width and tracking error on optical performance were studied. Fi- nally, the optimization model was established and optimization method was presented to determine optimal collector parameters based on particle swarm optimization and Monte Carlo method. The calculation results show that the off- set of light spot has a minimum value as the boundary half angle 45°.
