面向建筑屋顶分布式风能及风光互补能源利用的技术需求，提出并研究了一种新型风光互补系统的空间支撑框架。该框架通过配置导流板同时具有集风、稳流的作用，可显著增强小型垂直轴风力机的发电效率。首先采用理论分析方法，对空间支撑框架的集风效果及发电效率进行了分析。在此基础上，采用数值模拟的方法，分析了在不同风攻角下导流板间距、宽度对支撑框架内部气流速度、湍流动能的影响，并给出了优化参数。最后，采用风洞试验，对空间支撑框架作用下的小型风机发电性能进行了试验研究。研究表明，该空间支撑框架能够显著提高进入集风装置的气流速度，并降低内部空间湍流动能。当支撑框架配置间距D＝0.53 m，宽度W＝0.12 m的导流板时，可使风速增加约1.21倍，发电机功率提高约1.77倍。

The technological demand for distributed wind energy and wind-solar complementary energy utilization on building roofs was addressed. A new type of spatial support frame for wind-solar complementary systems was proposed. The power generation efficiency of small vertical axis wind turbines was enhanced by using flow deflectors with combined wind collection and flow stabilization functions. The wind collection effect and power generation efficiency of the framework were analyzed through theoretical methods. Numerical simulations were conducted to study the impact of flow deflector distancing and width on internal airflow velocity and turbulent kinetic energy at different wind attack angles. Optimization parameters were identified. Wind tunnel experiments were performed to investigate the power generation performance of small wind turbines with the spatial support framework. The results show that the framework significantly increases the airflow velocity entering the wind collection device and reduces turbulent kinetic energy in the internal space. When the flow deflectors have a distance of 0.53 m and a width of 0.12 m, the wind speed increases by 1.21 times and the generator power increases by about 1.77 times.
