According to the geometry and optical characteristics of trough concentrator, a new method for calculating the focal fluence distribution of trough solar concentrator using Origin software is proposed. Taking the plane focal line of the parabolic trough condenser as an example, the steps of the calculation method are introduced in detail. The calculated results are compared with the measured ones. The agreement between the two is in good agreement, which proves the feasibility and correctness of the calculation method. The function of the calculation method is relatively simple and clear, without programming, less calculation and fast calculation speed, and is suitable for any faceted groove concentrator and linear receiver, which can provide reference for the optimization design of trough solar concentrating system .
