摘要：在研究传统的太阳能烟囱模型的基础上，用风力发电机的塔筒代替太阳能烟囱，在塔筒底部增设集热棚，内部安装涡轮发电机进行研究，分析其可行性和各个环节的影响因素，以及它的发展前景。在给定的环境条件下，忽略空气在流动过程中的摩擦损失和散热，研究并计算出了每个能量转化过程的能量转化效率。算出在集热棚直径为200m，风机塔筒的直径为4m，高度为80m时，整个系统的能量转化率约为0.3%，涡轮机的最大可能输出功率为95.6kW。随后重点研究分析了太阳辐射强度、集热棚直径、塔筒高度等因素对涡轮机输出功率的影响。这种耦合发电系统与风力发电机本身的发电系统相结合，可以有效利用空间资源，在发电方面可以进行季节互补，适用于我国西部偏远地区的供电。23504

A New Type of System Combine Wind Power with Solar Thermal Power Generation
Abstract: On the basic study of the model of solar chimney, replace the chimney by the tower of wind driven generator, then set a collector on the bottom of the tower, analyze the feasibility and all the influence factor of every step as well as its development prospect. In the given environmental conditions, research and calculate the energy exchange efficiency of every energy conversion process neglect the frictional loss and the heat dissipation in the process of flow. Work out the whole energy exchange efficiency of all the energy conversion process is 0.3%, and the maximum possible power output of the turbine is 95.6kW when the diameter of collector is 200m, the diameter of the tower of the wind driven generator is 4m and the height of the tower is 80m. Afterwards, focused research and analyses the affection to the power output of the turbine of the factors such as the intensity of solar radiation, the diameter of collector and the height of the tower and so all. This type of electrical power generating system combined with the wind driven generator can effectively utilize the space resources，and it can be complementary to season In terms of power generation, it is suitable for the power supply of the remote areas of west China.
