摘　　要：依据太阳辐射实测数据,在分析全天太阳辐射特性的基础上,提出了基于日升、日落及太阳辐照度峰值的三点法太阳辐射实用模型。问题的关键在于如何确定太阳辐照度峰值,针对此提出两种解决方案,即基于国际通用辐射模型峰值的置信权重拟合和在实际允许误差范围内取邻近日拟合数据。理论分析和仿真结果表明,太阳辐照度理论预测值与实测值较吻合,可满足工程和科学研究的需要。According to the characteristic analysis of solar radiation data, a novel practical solar radiation model utilizing sunrise, sunset and radiation peak points （three-point-method）was proposed. Two solutions were put forward to deal with the radiation peak issue. One was based on the confidence weight evaluation of internationally popular radiation models and the other mainly took fitting data of near days into account with some permissible error. Both theoretic analysis and simulation results show that predicted data is close consistent with measured data, which is accurate enough for engineering applications.
